Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of data processing technology, and in particular to an online collaborative document editing method, system, device and medium. Background Art

[0002] At present, online collaborative document editing is a common form of web front-end document editing. Through online collaboration, multiple users can edit the same document. However, most online collaborative documents currently provide methods for multiple users to edit the same document, and different users can edit and view each other's content. It does not support the function of multiple users editing the same file in the same location and saving it separately. In order to collect documents from multiple users, in most cases, users send the same template file to individual users through other third-party communication software, and the users edit the documents locally and then submit them to the same user for aggregation. Users need to frequently exchange files in different communication software, which increases communication costs and time consumption. At the same time, the versions edited by each user may be inconsistent, resulting in difficulties in integration when the final aggregation is completed. In addition, the lack of real-time collaboration function makes it impossible to see other people's modifications in real time, which reduces the efficiency and flexibility of teamwork. Finally, the workload of managing and integrating multiple versions will also increase significantly.

[0003] It can be seen that there is an urgent need for an online collaborative document editing method with high collaborative efficiency and adaptability. Summary of the invention

[0004] In view of this, the embodiments of the present disclosure provide an online collaborative document editing method, system, device and medium, which at least partially solve the problems of poor collaborative efficiency and adaptability in the prior art.

[0050] The embodiment of the present disclosure provides an online collaborative document editing method, which can be applied to a document editing process in an office scenario.

[0051] See also Figure 1 , is a flow chart of an online collaborative document editing method provided by an embodiment of the present disclosure. Figure 1 and Figure 2 As shown, the method mainly comprises the following steps:

[0052] Step 1: A first user creates a master document and saves the master document on a server, wherein the master document includes a constant content area and a variable content area;

[0053] For example, the first user can create a project plan document that contains constant content areas (such as project goals, timelines, and team member information) and variable content areas (such as task assignments, progress updates, and notes). For example, the project goal section will always remain the same, while the task assignment section can be edited later, where team members can add their own tasks and progress. This document is saved on the server so that subsequent users can access and edit it.

[0054] Step 2: The first user generates a sharing link and sends the sharing link to the target user to be operated collaboratively;

[0055] Based on the above embodiment, step 2 specifically includes:

[0056] The first user generates a sharing link, which contains a unique document identifier, a unique user identifier, and a timestamp of the sharing time point. The sharing link is then sent to the target user to be collaborated with and a temporary signature is generated and saved on the server through a preset combination and encryption algorithm during sharing.

[0057] In specific implementation, the first user generates a sharing link that contains the document's unique identifier (12345), the user's unique identifier (67890), and the timestamp of sharing. At the same time, the system uses a preset combination of permutations and encryption algorithms to generate a temporary signature, such as abc123signature, and saves it on the server. The first user then sends this link to the target user, such as via email or chat application, to ensure that the target user can access the document securely.

[0058] Step 3: The target user opens the link and verifies the user information and permissions. The server generates a copy document that is identical to the main document based on the shared link and user information and synchronizes the edited information of the target user in the variable content area of ​​the copy document to the first user.

[0059] Based on the above embodiment, step 3 specifically includes:

[0060] Step 3.1, when the target user clicks the sharing link, determine whether the target user has logged in or registered, if so, execute step 3.3, if not, execute step 3.2;

[0061] Step 3.2, jump to the login page to log in, or jump to the registration page to register and log in;

[0062] Step 3.3, when the target user logs in, the document unique identifier, user unique identifier, and timestamp are obtained. A user signature needs to be generated through the same permutation combination and encryption algorithm. When the user signature is equal to the temporary signature, a copy document identical to the main document is generated;

[0063] Step 3.4, generate a user directory for each target user in the server;

[0064] Step 3.5: Synchronize the target user's editing information in the variable content area of ​​the copy document to the first user.

[0065] In specific implementation, if the user is not logged in or registered, the user will be redirected to the login / registration page to log in or register and log in. After logging in, the user opens the shared link and passes the signature to the server while passing his / her user unique identifier and the document unique identifier obtained from the shared link. When other users access this link, they need to obtain the document unique identifier, user unique identifier, and timestamp, and generate a sign through the same arrangement and encryption algorithm. If the sign is equal to the server's sign, the user is allowed to continue accessing. After verifying the signature, the server generates a copy of the document in the user directory based on the document unique identifier and the user unique identifier (if it already exists, it will not be copied). The document opened by the user is a copy document belonging to this user. The copy document contains all the original data of the document shared by the first user, including text content, non-editable areas and other information. The user can perform editing operations on the copy document, and editing this copy document will not affect the content of the main document shared by the first user. Other general users have no authority to view the new copy document, and the first user can view all other users' newly generated documents and document editing operations in real time.

[0066] For example, when the target user clicks on a shared link, the system first checks whether the user is logged in. If the target user is not logged in, the system automatically jumps to the login page. If the user does not have an account, a registration page is provided, and the user returns to the login page after completing the registration. Once the target user successfully logs in, the system extracts the document unique identifier, user unique identifier, and timestamp from the shared link. Next, the user generates a user signature, such as xyz456s i gnature, through the same permutation and encryption algorithm. The system checks whether the user signature is equal to the previously saved temporary signature abc123s i gnature. If they match, the system creates a copy document with the same structure as the main document, but the variable content area is empty or initialized as needed. The target user generates a user directory, such as / user / 67890 / documents, to store their copy documents and other related files. When the target user edits the variable content area of ​​the copy document, the system synchronizes these edits to the first user's view in real time. For example, if the target user adds a new task in the copy, the system will immediately send the task to the first user's interface through the server, ensuring that both users can see each other's changes in real time.

[0067] Step 4, synchronizing the first user's modification of the edited information to the corresponding target user;

[0068] Based on the above embodiment, step 4 specifically includes:

[0069] When the first user modifies the edit information, the modification of the edit information by the first user is synchronized to the corresponding target user using the operation conversion algorithm.

[0070] Furthermore, the step 4 also includes:

[0071] The modifications made by the first user to the invariable content area and the variable content area are synchronized to all target users.

[0072] In specific implementation, when the first user creates a master document, the system automatically marks the content area edited by the first user as an invariant content area. After sharing it with other users, other users cannot edit the invariant content area. When other users edit the variable content area, the updated content is not synchronized to the master document and the copy documents copied by other users. When the first user edits the invariant content area, the system synchronizes the edited content to the invariant area content corresponding to the copy documents of other users through the operational transformation (full name: Operational Transformation, abbreviated as OT) algorithm, so that the content of the master document is synchronized to each copy document in real time, and the invariant content areas of all documents are kept consistent. The first user can edit the copy documents of other users. When the first user and other users edit the copy documents at the same time, the OT collaborative editing algorithm is used to keep the document content consistent. OT is a relatively common online document collaboration algorithm, and there are already many mature solutions, which will not be discussed in detail here.

[0073] Step 5: When the target user completes editing, all contents in the copy document of each target user are saved to the server.

[0074] Based on the above embodiment, after step 5, the method further includes:

[0075] The corresponding copy document is retrieved from the server according to the query instruction of the first user.

[0076] Furthermore, the query instruction includes a document unique identifier or a user unique identifier.

[0077] In specific implementation, when the target user completes editing, all the contents of the copy document of each target user are saved in the user directory corresponding to each target user in the server. When other users open the link, a copy of the main document has been generated using the document unique identifier and the user identifier. The first user can query all generated copy documents uniformly using the main document unique identifier, or the first user can query copy documents corresponding to different target users based on the user unique identifier. In this system, a page is used to display a list of all copy documents. The first user can view the total number of copy documents, add, delete, modify, and check the content of each copy document, and can download all documents to the local computer with one click.

[0078] The online collaborative document editing method provided in this embodiment ensures that each user edits on the same basis by creating a master document and a copy document, thus avoiding version confusion. The online collaborative editing method allows multiple users to generate and edit new documents based on the same document as a template, and can submit different information, reducing the tedious process of editing and collecting documents. The real-time synchronization of editing information allows the first user to understand all modifications in a timely manner, thus promoting effective communication. At the same time, user authority verification enhances the security of the document, ensuring that only authorized users can access and edit the content. In addition, the editing results of all users are saved centrally to facilitate subsequent management and integration, and improve document editing efficiency and adaptability.

[0079] Corresponding to the above method embodiment, see Figure 3 The embodiment of the present disclosure further provides an online collaborative document editing system 30, including:

[0080] A creation module 301 is used for a first user to create a master document and save the master document on a server, wherein the master document includes a constant content area and a variable content area;

[0081] Sharing module 302, used for the first user to generate a sharing link and send the sharing link to a target user to be operated collaboratively;

[0082] Generating module 303, for the target user to open the link, and after verifying the user information and permissions, the server generates a copy document identical to the main document based on the sharing link and user information, and synchronizes the editing information of the target user in the variable content area of ​​the copy document to the first user;

[0083] Synchronization module 304, used to synchronize the modification of the edited information by the first user to the corresponding target user;

[0084] The saving module 305 is used to save all the contents of the copy document of each target user to the server after the target user completes editing.
