Method, device and computing device for document editing

[0001] This application claims priority to the Chinese patent application No. 202411336371.7, filed on September 24, 2024, with the State Intellectual Property Office of China, and entitled “Method, device and computing device for document editing”, the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of cloud computing, and more particularly, to a method, device and computing device for document editing. BACKGROUND

[0003] With the rapid development of computer application software, online documents such as web documents provide the function of simultaneous online editing for multiple users. Users can access the online document stored on the server through their respective terminal devices and perform corresponding editing operations on the online document. The server will update the online document in synchronization according to the editing operations performed by the users on the respective terminal devices to support multiple users to simultaneously edit the online document online.

[0004] In the related technical solution, multiple users establish a long connection between the terminal devices used by each user and the server, and send their respective operations on the document to the server through the long connection. The server then forwards the operations on the document to the terminal devices used by other users through the long connection, thereby realizing real-time synchronization of the document between the terminal devices and the server. In the related technology, a long connection is established between the terminal device and the server, and the power consumption of the terminal device is relatively large.

[0005] Therefore, how to reduce the power consumption of the terminal device has become a technical problem to be solved. SUMMARY

[0006] The present application provides a method for document editing, which can reduce the power consumption of the terminal device.

[0007] In a first aspect, a method for document editing is provided, which includes: a first terminal device obtaining a target document stored in a server from the server; the first terminal device generating a first editing operation on the target document and caching the first editing operation locally; the server determining that there is another terminal device editing the target document stored in the server, and sending a first notification message to the first terminal device; the first terminal device receiving the first notification message and synchronizing the first editing operation cached locally to the server according to the first notification message; and the server receiving the first editing operation and updating the target document stored on the server according to the first editing operation.

[0008] In the technical solution, the first terminal device generates the first editing operation on the target document, and the first editing operation is buffered locally without real-time collaboration between the terminal device and the server. When another terminal device edits the target document stored in the server, the first editing operation buffered locally is synchronized to the server. In this way, a long connection between the terminal device and the server is not required, thereby reducing power consumption of the terminal device and network traffic between the terminal device and the server.

[0009] With reference to the first aspect, in some implementations of the first aspect, the first terminal device establishes a short connection with the server, and the first terminal device acquires the target document stored in the server through the short connection.

[0012] In the technical solution, if the first terminal device acquires the target document stored in the server through the long connection, and no other terminal device edits the target document stored in the server, the first terminal device can disconnect the long connection, thereby reducing power consumption of the terminal device and network traffic between the terminal device and the server.

In this way, the number of network requests of the terminal device to the server can be reduced, and the server pressure can be reduced without sending a request to the server after each editing operation on the target document. The content of the target document stored in the server can be updated regularly, and the content of the target document stored in the server can be prevented from being too old.

[0068] For ease of description, the concepts involved in the embodiments of this application will be explained below.

[0069] 1. Short connection

[0070] A short connection refers to a brief connection established between a client and a server, which is closed immediately after a single communication session. In short connections, the client and server need to establish a connection, transmit data, and close the connection each time; there is no persistent connection.

[0071] As an example, short connections are primarily implemented using protocols such as the Hypertext Transfer Protocol (HTTP), and the connection is closed after each request-response cycle.

[0072] The aforementioned short connections are primarily suitable for non-real-time communication scenarios, such as file transfers and request-response applications. In these scenarios, short connections have shorter connection times and lower communication frequencies, thus avoiding prolonged consumption of server resources. Each communication is independent, saving resources. However, frequent connection and disconnection of short connections can impact communication efficiency and increase system overhead.

[0073] 2. Long connection

[0074] A persistent connection refers to a long-lasting connection maintained between a client and a server. Once established, this connection allows for extended communication. With a persistent connection, the client and server can send and receive data at any time without needing to re-establish and close the connection each time.

[0075] As an example, long connections are mainly implemented through protocols such as transmission control protocol (TCP) or WebSocket. In the TCP protocol, a long connection can be implemented by keeping a connection state after connection establishment, while in the WebSocket protocol, a more advanced real-time communication capability is provided.

[0076] The above long connection is mainly applicable to real-time application scenarios that require frequent communication, for example, real-time chat applications, real-time games, etc. In these scenarios, the client and the server need to maintain long-time and persistent communication in order to transmit data and state information in real time. Using a long connection can reduce the overhead of establishing a new connection, improve communication efficiency and stability. However, a long connection occupies certain resources due to a persistent connection maintained between the client and the server.

[0077] 3. Push service

[0078] The push service is a message push platform provided by a mobile phone manufacturer or a third-party supplier, which establishes a message push channel from the cloud to the terminal, and generally supports notification bar messages and transparent messages. The transparent message is a message processed by an application on the terminal device, and the terminal device does not directly display the transparent message pushed by the cloud, but transmits the data to the corresponding application on the terminal device, which analyzes the content and triggers relevant actions.

[0079] With the rapid development of computer application software, online documents such as web documents provide simultaneous online editing functions for multiple users. Users can access online documents stored on a server through their respective terminal devices and perform corresponding editing operations on the online documents. The server will update the online documents in synchronization according to the editing operations performed by the users on the respective terminal devices to support multiple users to simultaneously edit the online documents online.

[0080] In related technical solutions, multiple users establish long connections between their respective terminal devices and the server, and send their respective operations on the document to the server through the long connection, thereby realizing real-time synchronization of the document between the respective terminal devices and the server. In the related technology, since a long connection is established between the terminal device and the server, a persistent connection is maintained between the terminal device and the server due to the long connection. On the one hand, the power consumption of the terminal device is large, and on the other hand, the terminal device and the server will frequently receive and send through the long connection, resulting in a large consumption of network traffic.

[0081] Therefore, the embodiment of the present application provides a document editing method, which can not only reduce the power consumption of the terminal device, but also reduce the consumption of network traffic between the terminal device and the server.

[0082] For ease of description, the application scenario applicable to the present application is described in detail below in combination with FIG. 1-FIG. 2.

[0083] As an example, FIG. 1 is a schematic block diagram of an application scenario applicable to the embodiment of the present application. As shown in FIG. 1, the scenario can include at least one terminal device 110, a server 120. The at least one terminal device 110 is connected with the server 120 through a network.

[0084] The server 120 stores a document. When a certain user accesses the document stored in the server 120 through the terminal device 110 used by the user, other users can also access the document stored in the server 120 through the terminal devices 110 used by the users. When multiple users access the document through the terminal devices 110 used by the users, the document can be edited simultaneously. The server 120 can edit and update the document according to the content edited by each terminal device 110, and synchronize the updated document to each terminal device 110, so that each user can see the latest edited document through the terminal device 110 used by the user.

[0085] As an example, the at least one terminal device 110 is installed with a browser or an application (APP). A certain user accesses the document from the server 120 through the browser or the APP in the terminal device 110 used by the user, performs an editing operation on the document, and synchronizes the change of the content of the document between the server 120. Meanwhile, the server 120 can also synchronize the operation of the certain user on the document to other terminal devices 110 using the document.

[0086] As an example, the server 120 provides a collaboration service and a data service. A certain user accesses the collaboration service through the browser or the APP in the terminal device 110 used by the user to obtain the document from the server 120. The server 120 can also synchronize the operation of the certain user on the document to other terminal devices 110 using the document through the collaboration service.

[0087] As an example, the server 120 also provides a data service. The collaboration service in the server 120 can also persist the full change process data of the operation of the at least one terminal device 110 on the document to the data service.

[0088] The type of the terminal device 110 is not limited in the embodiments of this application. For example, the terminal device 110 can include, but is not limited to, at least one of the following: a personal computer, a notebook computer, a smart phone, and a tablet computer.

[0089] The type of the server 120 is not limited in the embodiments of this application. For example, the server 120 can be a single server in a cloud data center, or can also be a server cluster composed of multiple servers in a cloud data center.

[0090] FIG. 2 is a schematic block diagram of a cloud scenario suitable for the embodiments of this application. As shown in FIG. 2, the cloud scenario can include a cloud management platform 210, an Internet 220, and a client 230.

[0091] As shown in FIG. 2, the cloud management platform 210 is configured to manage an infrastructure that provides multiple cloud services. The infrastructure includes multiple cloud data centers, each of which includes multiple servers, and each of the servers includes cloud service resources and provides corresponding cloud services for users.

[0092] The cloud management platform 210 can be located in a cloud data center, which can provide an access interface (such as an interface or an application program interface (API)). The user can remotely access the access interface to register a cloud account and a password in the cloud management platform 210 by operating the client 230, and log in to the cloud management platform 210. After the cloud management platform 210 authenticates the cloud account and the password successfully, the user can further select and purchase a virtual machine with a specific specification (processor, memory, and disk) by paying a fee in the cloud management platform 210. After the payment and purchase are successful, the cloud management platform 210 provides a remote login account and password of the purchased virtual machine, and the client 230 can remotely log in to the virtual machine to install and run the user's application in the virtual machine. Therefore, the user can create, manage, log in to, and operate the virtual machine in the cloud data center through the cloud management platform 210. The virtual machine can also be referred to as a cloud server (elastic compute service, ECS) or an elastic instance (different cloud service providers have different names).

[0093] It should be understood that the user of the cloud service can be an individual, an enterprise, a school, a hospital, an administrative organ, etc.

[0094] The functions of the cloud management platform 210 include, but are not limited to, a user console, a computing management service, a network management service, a storage management service, an authentication service, and an image management service. The user console provides an interface or an API for user interaction, the computing management service is used to manage servers running virtual machines and containers and bare metal servers, the network management service is used to manage network services (such as gateways, firewalls, etc.), the storage management service is used to manage storage services (such as data bucket services), the authentication service is used to manage user account passwords, and the image management service is used to manage virtual machine images. The user uses the client 230 to log in to the cloud management platform 210 through the Internet 220 to manage the rented cloud services.

[0095] FIG. 3 is a schematic flowchart of a method for document editing according to an embodiment of the present application. As shown in FIG. 3, the method can include steps 310-350, which are described in detail as follows.

[0096] Step 310: The first terminal device acquires a target document stored in a server.

[0097] In the embodiment of the present application, the user can acquire the target document stored in the server through the first terminal device.

[0098] The user can acquire the target document stored in the server through a browser on the first terminal device, or can acquire the target document stored in the server through an application (APP) on the first terminal device, which is not limited in the present application.

[0099] There are various implementation manners for the first terminal device to acquire the target document stored in the server, which are not limited in the embodiment of the present application, and several possible implementation manners are listed as follows.

[0100] In one possible implementation manner, the first terminal device establishes a short connection with the server, and acquires the target document stored in the server through the short connection.

[0101] In another possible implementation manner, the first terminal device establishes a long connection with the server, and acquires the target document stored in the server through the long connection.

[0102] Step 320: The first terminal device generates a first editing operation on the target document, and caches the first editing operation locally.

[0103] In the embodiment of the present application, the first terminal device generates the first editing operation on the target document, and caches the first editing operation locally. That is, after the first terminal device generates the first editing operation on the target document, the first editing operation is not synchronized to the server in real time, but is cached locally.

[0104] As an example, the first editing operation includes a position where an object editing the target document is located and content of editing the object.

[0105] As an example, the object editing the target document can include, but is not limited to, a picture in the target document, a text in the target document, etc. The content of editing can include, but is not limited to, dragging a picture in the target document, changing a size of a picture in the target document, modifying a font of a text in the target document, modifying a color of a text in the target document, modifying a size of a text in the target document, etc.

[0106] Step 330: The server sends a first notification message to the first terminal device if there is another terminal device editing the target document stored in the server.

[0107] In the embodiment, the server can determine whether there is another terminal device editing the target document stored in the server after the first terminal device obtains the stored target document from the server.

[0108] In Example 1, if the server determines that there is another terminal device editing the target document stored in the server, the server sends a first notification message to the first terminal device, and the first notification message is used to notify the first terminal device that there is another terminal device editing the target document stored in the server.

[0109] In Example 2, if the server determines that there is another terminal device editing the target document stored in the server, the server sends a second notification message to the first terminal device, and the second notification message is used to notify the first terminal device that there is no other terminal device editing the target document stored in the server.

[0110] In the above Example 2, if the first terminal device obtains the target document stored in the server through a long connection, before the first terminal device generates the first editing operation of the target document, the first terminal device disconnects the long connection with the server according to the second notification message received by the first terminal device, so as to save the power consumption of the first terminal device.

[0111] Step 340: The first terminal device receives the first notification message and synchronizes the locally cached first editing operation to the server according to the first notification message.

[0112] In the embodiment, if the first terminal device receives the first notification message sent by the server, the first terminal device can determine that there is another terminal device editing the target document stored in the server according to the first notification message, and the first terminal device sends the locally cached first editing operation to the server according to the first notification message.

[0113] In a possible implementation, the first terminal device can re-establish a long connection with the server, and synchronize the first editing operation to the server through the long connection.

[0114] In another possible implementation, the first terminal device can establish a short connection with the server, and synchronize the first editing operation to the server through the short connection. For example, the short connection with the server can be established according to a set time period.

[0115] For example, the time period can be set according to the number of other terminal devices currently obtaining the stored target document from the server. For example, the more the number of other terminal devices currently obtaining the stored target document from the server, the shorter the time period. For another example, the less the number of other terminal devices currently obtaining the stored target document from the server, the longer the time period.

[0116] Step 350: The server receives the first editing operation, and updates the target document stored on the server according to the first editing operation.

[0117] In the embodiment of the application, after the server receives the first editing operation sent by the first terminal device, the server updates the target document stored on the server according to the first editing operation.

[0118] In a possible implementation, the server combines all editing operations on the terminal device side to update the target document stored on the server, thereby obtaining the updated target document.

[0119] For example, the first editing operation includes the position of the object edited in the target document and the content of the editing of the object. After the cloud server receives the first editing operation, the cloud server can edit the target document stored on the cloud server according to the edited position and the edited content included in the first editing operation, thereby realizing the synchronization of the target document between the first terminal device and the cloud server.

[0120] Optionally, in the case that the first terminal device exits the editing of the target document, if the second editing operation of the target document by the first terminal device is locally cached, the first terminal device establishes a short connection with the server, and sends the second editing operation to the server through the short connection. After the server receives the second editing operation, the server updates the target document stored on the server according to the second editing operation.

[0121] In the technical solution, the first terminal device generates the first editing operation on the target document, and the first editing operation is buffered locally without real-time collaboration between the terminal device and the cloud server. In the case that another terminal device edits the target document stored in the server, the first editing operation buffered locally is synchronized to the server. In this way, long-term long connection is not required between the terminal device and the cloud server, thereby reducing power consumption of the terminal device and consumption of network traffic between the terminal device and the server.

[0122] The different implementation processes of the method for editing a document shown in FIG. 3 will be described in detail below with reference to FIGS. 4-5. It should be understood that the examples of FIGS. 4-5 are only used to help those skilled in the art understand the embodiments of the present application, and the embodiments of the present application are not limited to the specific values or specific scenarios shown in the examples of FIGS. 4-5. Those skilled in the art can obviously make various equivalent modifications or changes according to the examples given below in FIGS. 4-5, and such modifications and changes also fall within the scope of the embodiments of the present application.

[0123] FIG. 4 is a schematic flowchart of another method for editing a document according to an embodiment of the present application. As shown in FIG. 4, the method can include steps 410-470, which will be described in detail below.

[0124] In step 410, the user 1 sends a request message for attempting to establish a long connection to the cloud server through the APP 1 on the terminal device 1.

[0125] In the embodiments of the present application, the user 1 can send a request message for attempting to establish a long connection to the cloud server through the APP 1 on the terminal device 1, so as to obtain the target document stored on the cloud server through the long connection between the APP 1 and the cloud server.

[0126] As an example, the cloud server is provided with a collaboration service, and the request message sent by the user 1 to the cloud server through the APP 1 is used to request to attempt to establish a long connection with the collaboration service on the cloud server.

[0127] The request message can include identification information of the APP.

[0128] In step 415, the cloud server sends a response message that does not require the establishment of a long connection to the APP 1 on the terminal device 1.

[0129] In the embodiment, after receiving the request message for attempting to establish a long connection sent by APP1 on the terminal device 1, the cloud server can send a response message for notifying APP1 that it is not necessary to establish a long connection with APP1 to APP1 according to the following information: 1, judging that the request message is sent by APP according to the identification information of APP in the request message; 2, no other user accesses the target document currently except user 1.

[0130] Step 420: APP1 and the cloud server establish a short connection, and the target document is acquired.

[0131] In the embodiment, after receiving the response message for not establishing a long connection sent by the cloud server, APP1 can establish a short connection with the cloud server, and acquire the target document stored on the cloud server through the short connection.

[0132] As an example, APP1 can send a request message for acquiring the target document to the cloud server through the short connection established above, the cloud server can send the target document stored by it to APP1 after receiving the request message, and user 1 can view the target document displayed on APP1 through the display interface of the terminal device 1.

[0133] Step 425: User 1 performs an editing operation on the target document through APP1, and stores the edited target document locally.

[0134] In the embodiment, after acquiring the target document, user 1 can perform an editing operation on the target document through APP1, and store the edited target document locally.

[0135] Step 430: User 2 establishes a long connection with the cloud server, and acquires the target document from the cloud server through the long connection.

[0136] In the embodiment, if user 2 wants to acquire the target document from the cloud server, the user 2 can send a request message for establishing a long connection to the cloud server through APP or browser 1 on the terminal device 2. After the cloud server establishes a long connection with the APP or browser of user 2, user 2 acquires the target document from the cloud server through the APP or browser.

[0137] In order to facilitate description, the following takes an example of user 2 establishing a long connection with the cloud server through browser 1.

[0138] Step 435: User 2 realizes synchronization of the target document through the long connection between browser 1 and the cloud server.

[0139] As an example, after the user 2 obtains the target document from the cloud server through the browser 1, the user 2 can edit the target document locally and send the edited result to the cloud server, so as to synchronize the target document between the browser 1 and the cloud server.

[0140] For example, the user 2 sends the editing operation information to the cloud server through the browser 1, the editing operation information including the position of the object edited in the target document and the content of the editing. After the cloud server receives the editing operation information, the cloud server can edit the target document stored thereon according to the editing position and the editing content included in the editing operation information, so as to synchronize the target document between the APP 2 and the cloud server.

[0141] As an example, the object edited in the target document can include but is not limited to a picture in the target document, a text in the target document, etc. The editing content can include but is not limited to dragging a picture in the target document, changing the size of a picture in the target document, modifying the font of a text in the target document, modifying the color of a text in the target document, modifying the size of a text in the target document, etc.

[0142] Step 440: The cloud server sends a PUSH transparent message to the APP 1.

[0143] As an example, after the cloud server establishes a long connection with the browser 1 used by the user 2, the cloud server sends a PUSH transparent message to the APP 1 used by the user 1, the PUSH transparent message being used to indicate that the APP 1 has other users online to access the target document in addition to the user 1.

[0144] Step 445: The APP 1 actively establishes a long connection with the cloud server according to the PUSH transparent message.

[0145] In the embodiment of the application, the APP 1 receives the PUSH transparent message sent by the cloud server, and can actively establish a long connection with the cloud server based on the PUSH transparent message.

[0146] Step 450: The user 1 synchronizes the target document through the long connection between the APP 1 and the cloud server.

[0147] As an example, the user 1 can obtain the target document from the cloud server through the long connection established between the APP 1 and the cloud server. After the user 1 obtains the target document through the APP 1, the user 1 can edit the target document locally and send the edited result to the cloud server, so as to synchronize the target document between the APP 1 and the cloud server.

[0148] For example, user 1 sends an editing operation information to the cloud server through APP 1, the editing operation information including an editing position and editing content of the target document. After receiving the editing operation information, the cloud server can edit the target document stored thereon according to the editing position and editing content included in the editing operation information, thereby realizing synchronization of the target document between APP 1 and the cloud server.

[0149] In the embodiment of the present application, the cloud server can also send the editing operation (including the editing position and editing content) of the target document by user 1 through APP 1 to browser 1, so as to synchronize the target document edited by user 1 between browser 1 and the cloud server.

[0150] Thereafter, the editing operation of the target document by user 1 through APP 1 and the editing operation of the target document by user 2 through browser 1 are all sent to the cloud server through the respective long connections, and forwarded by the cloud server to other users including user 1 and user 2, thereby realizing synchronization of the target document between the cloud server and each user accessing the target document.

[0151] Step 455: When user 2 exits the editing of the target document, user 2 closes the long connection between browser 1 and the cloud server.

[0152] In the embodiment of the present application, when user 2 exits the editing of the target document, user 2 can close the long connection between browser 1 and the cloud server.

[0153] Step 460: The cloud server closes the long connection between itself and APP 1.

[0154] In the embodiment of the present application, when the cloud server judges that there is only one connection APP 1 after browser 1 closes the long connection with the cloud server, the cloud server can close the long connection between itself and APP 1, and keep the online state of user 1. At this time, the cloud server and APP 1 have been disconnected, and the subsequent modification of the target document by user 1 can be saved only locally.

[0155] Step 465: When user 1 exits the editing of the target document, user 1 sends a request message for clearing user state to the cloud server through APP 1.

[0156] In the embodiment of the present application, when user 1 exits the editing of the target document, user 1 can send a request message for clearing user state to the cloud server through APP 1, so as to mark the state of user 1 as offline by the cloud server.

[0157] Optionally, if user 1 still edits the target document during the disconnection of APP1 and the cloud server, APP1 can also save the edited target document locally. And APP1 can also establish a short connection with the cloud server, and send the result of this editing to the cloud server through the short connection.

[0158] Step 470: The cloud server marks user 1 as offline.

[0159] In the embodiment of the application, after receiving the request message for clearing the user state sent by APP1, the cloud server marks the state of user 1 as offline.

[0160] In the above technical solution, since most of the scenarios are single-user editing of the target document, there is no need to perform real-time collaboration between the terminal device and the cloud server for the edited document, and thus there is no need to maintain a long-term long connection between the terminal device and the cloud server, thereby reducing the power consumption of the terminal device and the consumption of network traffic between the terminal device and the server.

[0161] FIG. 5 is a schematic flowchart of another method for document editing provided by an embodiment of the application. As shown in FIG. 5, the method can include steps 510-580, which are described in detail as follows.

[0162] Step 510: User 1 establishes a long connection between APP1 on terminal device 1.

[0163] In the embodiment of the application, user 1 can send a request message for establishing a long connection to the cloud server through APP1 on terminal device 1, so as to obtain the target document stored on the cloud server through the long connection between APP1 and the cloud server. After receiving the request message for establishing a long connection sent by APP1, the cloud server establishes a long connection with APP1.

[0164] Step 515: User 1 obtains the target document from the cloud server through the long connection between APP1 and the cloud server.

[0165] In the embodiment of the application, after the cloud server establishes a long connection with APP1 of user 1, user 1 can obtain the target document from the cloud server through APP1.

[0166] It should be understood that the specific process of how APP1 obtains the target document from the cloud server is described in step 420, which will not be described here.

[0167] Step 520: The cloud server sends a notification message to APP1.

[0168] In the embodiments of the present application, the cloud server can send a notification message to APP1, and the message contains a list of all online users.

[0169] Step 525: User 1 sends a notification message to the cloud server through APP1, which indicates that the long connection is disconnected.

[0170] In the embodiments of the present application, after APP1 receives the notification message sent by the cloud server, it is determined that no other user accesses the target document according to the user list, and user 1 can send a notification message to the cloud server through APP1, which indicates that it is temporarily offline and the long connection between it and the cloud server is disconnected.

[0171] Step 530: The cloud server disconnects the long connection between it and APP1, and records that user 1 is online.

[0172] In the embodiments of the present application, after the cloud server receives the notification message sent by user 1 through APP1, which indicates that it is temporarily offline and the long connection between it and the cloud server is disconnected, it disconnects the long connection between it and APP1 and records that user 1 is online.

[0173] Step 535: User 1 edits the target document through APP1 and stores the edited target document locally.

[0174] In the embodiments of the present application, after the long connection between APP1 and the cloud server is disconnected, user 1 can edit the target document obtained by it through APP1 and store the edited target document locally.

[0175] Step 540: User 2 connects a long connection between the cloud server and the browser 1 on the terminal device 2, and obtains the target document from the cloud server through the long connection.

[0176] Step 545: User 2 realizes synchronization of the target document through the long connection between the cloud server and the browser 1 on the terminal device 2.

[0177] Step 550: The cloud server sends a PUSH transparent message to APP1.

[0178] Step 555: APP1 actively establishes a long connection with the cloud server according to the PUSH transparent message.

[0179] Step 560: User 1 realizes synchronization of the target document through the long connection between APP1 and the cloud server.

[0180] Step 565: When user 2 exits the editing of the target document, user 2 closes the long connection between the cloud server and the browser 1.

[0181] Step 570: The cloud server closes the long connection between it and APP1.

[0182] Step 575: When the user 1 exits the editing of the target document, the user 1 sends a request message for clearing the user state to the cloud server through the APP 1.

[0183] Optionally, when the user 1 has further editing on the target document before exiting the editing of the target document, a short connection is established between the APP 1 and the cloud server, and the result of the current editing is sent to the cloud server through the short connection.

[0184] Step 580: The cloud server marks that the user 1 is offline.

[0185] It should be noted that steps 540-580 are similar to steps 430-470, and details are referred to the description in steps 430-470, which will not be repeated here.

[0186] In the above technical solution, in the case of the long connection between the terminal device and the cloud server, the power consumption of the terminal device and the consumption of the network traffic between the terminal device and the server can be reduced.

[0187] Optionally, in some embodiments, the first terminal device can also realize the synchronization of the document with the server through the short connection, which will be described in detail below in combination with FIG. 6.

[0188] FIG. 6 is a schematic flowchart of another method for editing a document according to an embodiment of the present application. As shown in FIG. 6, the method can include steps 610-640, which will be described in detail below.

[0189] Step 610: The first terminal device acquires the target document stored in the server through a short connection.

[0190] As an example, the first terminal device can establish a short connection with the server, and acquire the target document stored in the server through the short connection.

[0191] For example, the user can establish a short connection with the server through the APP on the first terminal device, send a request message for acquiring the target document to the server through the short connection, and the server can send the target document stored by the server to the APP on the first terminal device after receiving the request message. The user can view the target document displayed on the APP through the display interface of the first terminal device.

[0192] Step 620: The first terminal device generates a first editing operation on the target document, and caches the first editing operation locally.

[0193] In the embodiment of the present application, before step 620, the first terminal device can set a time period for synchronizing the first editing operation to the server, for example, a first time period.

[0194] For example, the user can set the time period for synchronizing the document through the APP on the first terminal device. The time period for synchronizing the document refers to the period in which the APP on the first terminal device synchronizes the locally cached first editing operation on the target document to the server. That is, when the user edits the target document through the APP on the first terminal device, the user can perform multiple first editing operations on the target document through the APP on the first terminal device within the time period specified by the timing mechanism, and cache the multiple first editing operations locally, and then synchronize the locally cached first editing operation on the target document to the server according to the set time period.

[0195] For example, the time period can be that the locally cached first editing operation on the target document is synchronized to the cloud server once every n minutes. For example, the server is synchronized once every 30 minutes or 60 minutes.

[0196] In the above technical solution, the first editing operation on the target document can be stored locally first, and then the cached first editing operation is synchronized to the server according to a certain time period. In this way, the number of network requests of the terminal device to the server can be reduced, and the server does not need to send a request every time the target document is edited, thereby reducing the pressure on the server. In addition, the content of the target document stored in the server can be updated regularly, so that the content of the target document stored in the server is not too old.

[0197] In the embodiment of the present application, after the first terminal device obtains the target document, a timer of a first time period can be started. The user can edit the target document through the first terminal device, and the first editing operation on the target document can be stored locally before the first time period specified by the timer expires.

[0198] Step 630: The first terminal device sends the locally cached first editing operation to the server through the short connection according to the set first time period.

[0199] In a possible implementation, when the timing time of the first time period arrives, the first terminal device establishes a short connection with the server, and sends the locally cached first editing operation to the server through the short connection.

[0200] Step 640: The server receives the first editing operation, and updates the target document stored in the server according to the first editing operation.

[0201] In the embodiment of the present application, after the server receives the first editing operation sent by the first terminal device, the server updates the target document stored in the server according to the first editing operation.

[0202] Optionally, it is assumed that there are other terminal devices that need to obtain the stored target document from the server and edit the target document. For example, a second terminal device obtains the target document stored in the server from the server through a short connection, the second terminal device generates a third editing operation on the target document, and caches the third editing operation locally. According to a set second time period, the second terminal device sends the third editing operation cached locally to the server through the short connection, and after the server receives the third editing operation, the server updates the target document stored in the server according to the third editing operation.

[0203] Optionally, in the embodiment of the present application, when the user needs to exit the editing of the target document, if there is a second editing operation on the target document cached locally before the user exits the editing of the target document, the user can establish a short connection between the first terminal device and the server, and synchronize the second editing operation on the target document cached locally before the user exits the editing of the target document to the cloud server through the short connection, so as to realize the synchronization of the document between the first terminal device and the server.

[0204] In the above technical solution, the edited document does not need to be synchronized in real time between the terminal device and the server, and the synchronization of the target document between the terminal device and the server can be realized through a short connection according to a set time period, so as to further reduce the power consumption of the terminal device and the consumption of network traffic between the terminal device and the server.

[0205] The above describes the document editing method provided by the embodiment of the present application in combination with FIG. 1 to FIG. 6, and the following will describe the embodiment of the device of the present application in combination with FIG. 7 to FIG. 10.

[0217] The following describes in detail a computing device provided by an embodiment of the present application in combination with FIG. 8.

[0218] FIG. 8 is an architecture diagram of a computing device 1500 provided by an embodiment of the present application. The computing device 1500 can be a server or a computer or other device with computing capability. The computing device 1500 shown in FIG. 8 includes at least one processor 1510 and a memory 1520.

Among them, the general processor is a microprocessor and the like. For example, the processor 1510 is a central processing unit (CPU).

[0225] Optionally, each processor 1510 includes at least one processing unit 1512 and a memory control unit 1514.

[0226] Optionally, the processing unit 1512 is also called core or kernel, which is the most important component of the processor. The processing unit 1512 is manufactured by single crystal silicon with a certain production process, and all the calculations, command receiving, command storage and data processing of the processor are executed by the core. The processing units respectively independently run program instructions, and use the parallel computing capability to speed up the program running. Various processing units have fixed logic structures, for example, the processing unit includes logic units such as a first level cache, a second level cache, an execution unit, an instruction level unit and a bus interface.

[0227] In one implementation, the memory control unit 1514 is used to control the data interaction between the memory 1520 and the processing unit 1512. Specifically, the memory control unit 1514 receives a memory access request from the processing unit 1512, and controls the access to the memory based on the memory access request. As an example but not limitation, the memory control unit is a memory management unit (MMU) and the like.

[0228] In one implementation, each memory control unit 1514 addresses the memory 1520 through a system bus. And an arbiter (not shown in FIG. 8) is configured in the system bus, which is responsible for processing and coordinating the competitive access of multiple processing units 1512.

[0229] In one implementation, the processing unit 1512 and the memory control unit 1514 are communicatively connected through the internal connection line of the chip, such as the address line, so as to realize the communication between the processing unit 1512 and the memory control unit 1514.

[0230] Optionally, each processor 1510 also includes a cache 1516, which provides temporary storage of often-used data and instructions. Recent use patterns of the data can be tracked by the cache control 1518 in order to maximize the effectiveness of the cache 1516. The cache 1516 is typically more expensive per byte of storage than the main memory 1520, but is faster. Therefore, the cache 1516 acts as a bridge between the main memory 1520 and the processor 1510, allowing the processor 1510 to run faster while the more expensive cache 1516 does the work of fetching data and instructions and storing the results of access intensive workloads.

[0231] The memory 1520 can provide a space for processes in the computing device 1500 to run, for example, the memory 1520 stores computer programs (in particular, the codes of the programs) for generating the processes. After the computer programs are run by the processor to generate the processes, the processor allocates corresponding storage spaces in the memory 1520 for the processes. Further, the storage spaces further include a text segment, an initialized data segment, a bit initialized data segment, a stack segment, a heap segment, and the like. The memory 1520 stores data generated during the running of the processes, for example, intermediate data, or process data, and the like, in the storage spaces corresponding to the processes.

[0232] Optionally, the memory is also referred to as the internal memory, which is used to temporarily store the data for operation in the processor 1510, and exchange the data with the external memory such as the hard disk. As long as the computer is running, the processor 1510 will call the data needed for operation to the internal memory for operation, and the processing unit 1512 will transmit the results after the operation is completed.

[0233] By way of example, and not limitation, memory 1520 is volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory. By way of example, and not limitation, nonvolatile memory can be read-only memory (ROM), programmable ROM (PROM), erasable PROM (EPROM), electrically EPROM (EEPROM), or flash memory. Volatile memory is random access memory (RAM), which acts as external cache. By way of example, and not limitation, many forms of RAM are available, such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double-data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), and direct rambus RAM (DR RAM). The system and method described herein can be stored on or transmitted across one or more of these forms of RAM, or nonvolatile memory.
