[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] At present, although the complete document transmission method is simple and easy to implement, for large-file contract documents, the transmission time is long and the system response is slow, resulting in poor user experience. In an environment with limited network bandwidth, the long loading time may even cause the request to time out and fail. Although the server-side rendering method reduces the processing burden on the client, it will cause the display to be unsmooth due to network delays, and the client and server need to communicate frequently to transmit images or texts, which brings high transmission pressure and affects the user experience. Therefore, when facing large files, the above two implementation methods usually have problems such as slow loading, long time, and untimely signing and approval synchronization, thereby reducing the user experience.

[0027] Based on the above problems, the present invention provides a method for adding file approval. By adopting slice loading, the client only requests the document page fragment that needs to be displayed, and there is no need to load the entire document at one time, thereby reducing the waiting time for the initial loading, improving the efficiency of online approval of layout documents, enhancing the overall operating experience, and reducing bandwidth consumption, making the system more adaptable, and particularly suitable for use on mobile terminals or in low-bandwidth environments.

[0028] Combine the following Figure 1-Figure 3 The method for adding file signatures and approvals of the present invention is described. The method for adding file signatures and approvals is applicable to adding signatures and approvals to any file. The execution subject of the method can be an electronic device or a device for adding file signatures and approvals set in the electronic device. The device for adding file signatures and approvals can be implemented by software, hardware, or a combination of both.

[0029] Figure 1 This is one of the flow charts of the method for adding a document signature provided by the present invention, such as Figure 1 As shown, the method is applied to the client and includes the following: Step 101: determine at least one slice page range corresponding to the target page in the file to be added for approval based on the page number information of the file to be added for approval sent by the server, the data volume information of the file to be added for approval sent by the server, and the data volume condition of the target page transmitted in the file to be added for approval.

[0030] The data volume condition is used to characterize the transmission speed of the file to be added for signature and approval; The slicing page range is the range for slicing the target page in the file to be added for signature and approval.

[0031] Here, the client includes but is not limited to mobile phones, computers, tablets, etc.

[0032] Here, approval refers to any form of content added by a user to a document, including but not limited to user signature, annotations to a document, modification to a document, or adding an image to a document.

[0033] Here, the data volume information refers to the size of the space occupied by the file to be added for approval.

[0034] Here, the target page may be a page that the client needs to load at one time, or a page that requires the user to add a signature. The target page includes one or more pages.

[0035] The data volume condition for the target page to be added to the signature approval file can be obtained from the client or from the server, which is not limited in the present invention.

[0036] In one embodiment, the data amount condition for target page transfer may be any appropriate threshold, such as 5 megabytes (MB), 6 MB, etc.

[0037] In one embodiment, after the client initiates a request to the server to obtain basic information of the file to be added for approval, the server responds to the request and sends the client information about the number of pages in the file to be added for approval and the amount of data in the file to be added for approval. Here, in addition to the number of pages and amount of data in the file to be added for approval, the basic information may also include the types of operations supported by the file.

[0038] Here, the method for determining the slice page range can be any appropriate method, for example, the slice page range is determined based on the mapping relationship between the number of pages information, the data volume information, the data volume conditions of the target page transmitted in the file to be added for approval, and the slice page range; for another example, the slice page range is calculated based on the number of pages information, the data volume information, and the data volume conditions of the target page transmitted in the file to be added for approval.

[0039] Exemplarily, the method determines at least one slice page range corresponding to the target page in the file to be added for approval based on the page number information of the file to be added for approval sent by the server, the data volume information of the file to be added for approval sent by the server, and the data volume condition of the target page transmitted in the file to be added for approval, including: determining the target page based on the page number information of the file to be added for approval and the data volume information of the file to be added for approval; determining at least one slice page number corresponding to the target page based on the data volume information of the target page and the data volume condition of the target page transmitted; and determining the at least one slice page range based on each slice page number.

[0040] Here, the data volume information of the target page can be sent by the server to the client after the client makes a request to the server; or it can be sent by the server to the client after the client initiates a request to the server to obtain the basic information of the document to be added for approval, and the basic information includes the data volume of each page of the document. The present invention does not limit the method for obtaining the data volume information of the target page.

[0041] It should be noted that if the data volume of the target page is less than the threshold, there is no need to adjust the number of slice pages; if the data volume of the target page is greater than the threshold, the transmission efficiency will be under pressure, and the number of slice pages needs to be divided into two groups to reduce the number of slice pages for each document, and continue to determine whether the data volume after reducing the number of slice pages is less than the threshold. If it is greater than the threshold, continue to group until the data volume is less than the threshold, and use the final number of slice pages as the slice page range.

[0042] In another embodiment, the data volume condition for the target page transmission may also be whether the data volume of the target page is less than a preset threshold. If the data volume of the target page meets the data volume condition, the slice page is not adjusted; if not, the slice page is divided into two groups, and it is further determined whether the data volume after grouping meets the data volume condition. If the data volume condition is not met, the grouping is continued until the data volume condition is met to obtain the slice page range.

[0043] For example, the document to be added for signature and approval contains 50 pages of content and a data volume of 30 megabytes. The slicing loading method of 5 pages at a time is adopted. Here, the target pages are pages 1 to 5. The client requests the document data volume of pages 1 to 5 from the server, and determines whether the document data volume is less than the fast transmission condition (i.e., the data volume condition). If it is less, the slicing page range is determined to be pages 1 to 5; otherwise, the slicing page range is reduced and pages 1 to 5 are sent separately, for example, 1 to 3 are divided into one slicing page range, and 4 to 5 are divided into another slicing page range.

[0044] In the embodiment of the present invention, the number of slice pages is dynamically adjusted according to the data volume of the page content, which can not only meet the requirements of fast transmission, but also avoid transmission congestion by reducing the number of slice pages when the document content is large. This flexible slicing method not only improves transmission efficiency, but also avoids excessive occupation of system resources.

[0045] Step 102: Send a slice request carrying the range of each slice page to the server.

[0046] Here, the client can send one request carrying the slice page range to the server at a time, or send multiple slice requests carrying the slice page range at the same time.

[0047] Exemplarily, a specific method for simultaneously sending multiple slice requests carrying slice page ranges includes: creating a corresponding thread for each slice page range; and sending the corresponding slice page range to the server based on the thread corresponding to each slice page range.

[0048] Here, a thread is the smallest unit in which the operating system can perform computational scheduling. Multiple threads can be executed concurrently in the same process. That is, sending a slice request is a process, and the process sending the slice request can concurrently send multiple slice page ranges to the server.

[0049] In the embodiment of the present invention, a multi-threaded request is initiated on the client, so that page loading can be processed in parallel, which improves the loading speed and response speed, and further enhances the user experience when opening a document for the first time.

[0050] Step 103: Receive the slice document sent by the server.

[0051] The slicing document is obtained by the server slicing the target page based on the slicing page ranges.

[0052] Here, the slice document is a part of the document to be approved.

[0053] In an embodiment of the present invention, the server may send the slice document by breakpoint resume transmission or multi-thread transmission.

[0054] In one embodiment, in order to better ensure the integrity of the document, the slice document may include a document identifier (ID).

[0055] Step 104: Based on the slice document, add approval to the file to be added.

[0056] In the embodiment of the present invention, after receiving the slice document, the client determines from the slice document a page to which approval needs to be added, and adds the approval to the page.

[0057] Furthermore, adding approvals to the file to be added based on the slice document includes: parsing the slice document and displaying the first page in the slice document; preloading the first n pages of the first page and the last n pages of the first page; in response to the user's operation of adding approvals, adding approvals on the pages to be added in the file to be added, where n is an integer greater than or equal to 1; the pages to be added are one or more of the first page, the first n pages, and the last n pages.

[0058] Here, the first page may be a page specified by the user; or may be a starting page of the slice document.

[0059] Here, after parsing the slice document, the document content in the slice document is obtained and stored in the cache, and then the first page is loaded and displayed on the client. The client automatically preloads the first n pages and the next n pages, and displays the first n pages or the next n pages according to the user's page turning instructions.

[0060] In the embodiment of the present invention, the setting of preloading pages (current page, previous page, next page) ensures a smooth experience for users when turning pages without any perception, avoiding the phenomenon of freezing. For smaller documents, all pages can be preloaded at one time, improving the reading and approval fluency of users.

[0061] It should be noted that the number of preloaded pages can be a pre-set appropriate number of pages, such as 3 pages, the previous page (nk), the current page (n), and the next page (n+k), where k=1 (the k value can be adjusted according to actual needs to adjust the number of preloaded pages). The sliced ​​document must contain at least 3 pages of content. If the total number of pages in the document is less than 3, all of them are loaded. If it is greater than 3 pages, and the last sliced ​​document has less than 3 pages, all the remaining pages are loaded.

[0062] In an embodiment of the present invention, based on the page number information of the file to be added for approval sent by the server, the data volume information of the file to be added for approval sent by the server, and the data volume condition of the target page in the file to be added for approval, at least one slice page range corresponding to the target page in the file to be added for approval is determined, and a slice request carrying each slice page range is sent to the server, so that the server divides the target page into multiple slice documents according to the slice page range and sends them to the client, and the client adds the approval to the file to be added for approval according to the slice document. In this way, by adopting slice loading, the client only requests the document page fragments that need to be displayed, and there is no need to load the entire document at one time, which reduces the waiting time for the initial loading, improves the efficiency of online approval of layout documents, improves the overall operating experience, and reduces bandwidth consumption, making the system more adaptable, especially suitable for use on mobile terminals or in low-bandwidth environments.

[0063] Figure 2 FIG. 2 is a flow chart of the method for adding a document signature provided by the present invention. Figure 2 As shown, the method is applied to the server and includes the following: Step 201: Obtain page number information of the document to be added for approval and data volume information of the document to be added for approval.

[0064] Step 202: Send the page number information of the file to be added for approval and the data volume information of the file to be added for approval to the client.

[0065] The page number information of the file to be added for approval and the data volume information of the file to be added for approval are used by the client to determine at least one slice page range corresponding to the target page in the file to be added for approval.

[0066] Step 203: Receive a slice request sent by the client and carrying the range of each slice page.

[0067] Here, the way the client sends a slice request can refer to the above step 201 and will not be repeated here.

[0068] Step 204: based on each of the slice page ranges, slice the target page to obtain a slice document.

[0069] Furthermore, based on each of the slicing page ranges, the target page is sliced ​​to obtain a slice document, including: based on the slicing page range, the target page is sliced ​​to obtain the document content corresponding to the slicing page range and the data volume corresponding to the slicing page range; based on the data volume corresponding to the slicing page range, the number of slice pages corresponding to the slicing page range is adjusted to obtain a target number of slice pages; based on the target number of slice pages, the document content is sliced ​​to obtain an initial slicing document; the initial slicing document, the identifier corresponding to the initial slicing document and the attribute information corresponding to the initial slicing document are encapsulated to obtain the slicing document.

[0070] Here, the attribute information is also called metadata information, which may include data volume information of the initial slice document and page number information of the initial slice document.

[0071] It should be noted that after receiving the slice page range, the server parses the file to be added for approval, extracts the target page, and slices the target page according to the slice page range to obtain the document content corresponding to the slice page range and the data volume corresponding to the slice page range. Then, it is determined whether the data volume corresponding to the slice page range is less than the threshold value. If it is less than, there is no need to adjust the number of slice pages; if it is greater, the slice page range needs to be grouped to reduce the number of slice pages until the data volume after reducing the number of slice pages is less than the threshold value to obtain the target number of slice pages; according to the target number of slice pages, the document content is continued to be sliced ​​to obtain the initial slice document, and the initial slice document, the identifier corresponding to the initial slice document, and the attribute information corresponding to the slice document are encapsulated to obtain the slice document.

[0072] In the embodiment of the present invention, if the document is complex and the amount of data on a single page is large, the number of slice pages is further adjusted through the server to ensure that the slice document is suitable for fast transmission.

[0073] Step 205: Send the slice document to the client.

[0074] The slice document is used by the client to add approval to the file to be added.

[0075] In an embodiment of the present invention, the client determines at least one slice page range corresponding to the target page in the file to be added for approval based on the page number information of the file to be added for approval sent by the server, the data volume information of the file to be added for approval sent by the server, and the data volume condition of the target page in the file to be added for approval, and sends a slice request carrying each slice page range to the server, so that the server divides the target page into multiple slice documents according to the slice page range and sends them to the client. The client adds the approval to the file to be added for approval based on the slice documents. In this way, by using slice loading, the client only requests the document page fragments that need to be displayed, and there is no need to load the entire document at one time, which reduces the waiting time for the initial loading, improves the efficiency of online approval of layout documents, improves the overall operating experience, and reduces bandwidth consumption, making the system more adaptable, especially suitable for use on mobile terminals or in low-bandwidth environments.

[0076] Furthermore, after sending the slice document to the client, the method also includes: receiving the approved slice document sent by the client; the approved slice document is obtained by the client in response to the user's submission operation for approval, integrating the approval time, user identification, approval text and approval image; merging the approved slice document into the file to be added for approval, to obtain the target file for adding approval.

[0077] Here, the approved slice document only contains the page where the approval information is located.

[0078] It should be noted that when the user triggers the approval completion operation, the client will assemble the approval page (number of pages >= 1) information, create a new slice document, and transmit it back to the server.

[0079] It should be noted that the method of merging the signed and approved sliced ​​document into the file to be added for approval can be any appropriate method, for example, extracting the front and back document fragments of the signed and approved sliced ​​document on the file to be added for approval, generating new sliced ​​documents respectively, and then splicing the three sliced ​​documents in sequence to generate a new approved document; for example, replacing the corresponding documents and contents in the file to be added for approval with the files and resource contents in the sliced ​​document to ensure the correctness of the document and form a new approved document.

[0080] In an embodiment of the present invention, the server may merge the approved sliced ​​documents into the file to be added for approval after each approval is completed, or after all approvals are completed, the document is closed to trigger a stitching operation.

[0081] In an embodiment of the present invention, the approved sliced ​​document only transmits the page content changed by the user, which reduces the amount of data transmitted. In the scenario where the document is frequently approved, the response speed of the system is ensured and the processing efficiency of the approval is improved.

[0082] The following is an application scenario of adding file approval provided by the present invention.

[0083] In this application scenario, an online contract review and approval system is developed. Users can browse and sign contract documents through the client. The document uses the OFD (Open Fixed-layout Document) format.

[0084] Figure 3 FIG. 3 is a flow chart of the method for adding a document signature provided by the present invention. Figure 3 As shown, the interaction between the client and the server includes: Step 301: The client requests basic document information from the server.

[0085] Step 302: The server returns basic document information to the client.

[0086] Specifically, the client sends a HyperText Transfer Protocol (HTTP) request to the server, which includes the ID of the file to be added for approval, the number of pages and data volume of the file to be added for approval, and the types of operations supported by the file to be added for approval; after receiving the request, the server reads the basic information of the document (for example, the total number of pages, file size, supported operation types, etc.), and encapsulates it into an object notation (JavaScript Object Notation, JSON) format and returns it to the client; the client parses the JSON data and reads that the total number of pages of the contract is 50 pages, the file size is 30MB, and the types of operations supported by the document are: approval, etc.

[0087] Step 303: The client sends a multi-threaded request for a slice document to the server.

[0088] For example, the client estimates the loading strategy based on the total number of pages and the file size, and decides to adopt the slicing loading method of 5 pages at a time, and initially loads the first 5 pages. Specifically, multi-threaded request setting: the client creates multiple threads, each thread is responsible for requesting a page segment, and requests pages 1-5 in parallel; slicing request sending: each thread sends the slicing page range (for example, "requesting pages 1 to 5") and the document ID to the server.

[0089] Step 304: The server returns the slice document to the client.

[0090] The server dynamically segments the OFD document and generates corresponding slices according to the requested page range. Specifically, document parsing: the server uses the OFD parser to load the target document; page extraction: the server extracts the page content, resources, metadata information, etc. according to the requested page range (such as pages 1-5); dynamic segmentation: the server dynamically determines the number of slice pages according to the page data volume. If the document is complex and the single page data volume is large, the number of pages can be reduced to ensure that the slice document is suitable for fast transmission; packaging and return: the server packages the slice document ID, page content, metadata and other information into an independent OFD document slice and returns it to the client; output data: return the slice document (OFD format file of pages 1-5).

[0091] Step 305: The client receives the slice document, displays the current page, and loads the first n pages and the next n pages.

[0092] The client receives the slice document and preloads it. The client receives and displays the slice documents on pages 1-5, and preloads them for a smoother reading experience. Specifically, slice parsing: the slice documents (pages 1-5) received by the client are decoded and stored in the cache; current page loading: page 1 is loaded by default (or the starting page specified by the user) and rendered to the interface; preloading mechanism: the client automatically preloads page 2 (the page after the current page, if the previous page exists, it also needs to be loaded). If the user jumps to an unloaded page (for example, page 6), a new request is triggered to load a new slice document; output data: currently displayed page, page 1, preloaded page, page 2.

[0093] Step 306: The user adds a signature on the page through the client.

[0094] Step 307: The client generates a signed and approved slice document and sends it to the server.

[0095] User approval operation, the user signs on page 2, and clicks "Submit" after completing the signature. Specifically, approval generation: the client integrates the user's signature information (such as signature image, text annotation) to generate a new "approval slice document", which only contains the page where the approval content is located (page 2); data encapsulation: the approval slice document contains page content and approval metadata (such as approval time, user ID, signature image, etc.); data transmission: the client sends the approval slice document to the server; output data: approval slice document (page 2, including approval information).

[0096] Step 308: The server puts the signed slice document into the cache queue.

[0097] Step 309: The server merges the signed and approved slice document into the file to be added for approval, generating a complete file including the approval.

[0098] The server-side approval merge operation, after receiving the approval slice document, merges the approval content back to the original document. Specifically, cache queue: the server puts the approval slice document into the cache queue and waits for the merge operation; select the merge method; merge execution: the server operates according to the selected merge method to generate a new version of the contract document containing the approval content; output data: the merged document version (including the approval on page 2). Among them, the merge method can include the following two methods: Method 1: Extract the context of the approved page, generate slice documents separately, and stitch them together in order to form a complete document.

[0099] Method 2: Directly replace the original content of the approval page to update the approval data.

[0100] Step 310: The user performs a page turning operation on the client.

[0101] Step 311: The client sends the next round of loading requests to the server.

[0102] Client page turning operation and loop loading: After the user finishes reading page 5, he turns the page down to page 6, triggering a new page loading request. Specifically, page judgment: the client judges that page 6 is not in the current slice cache; slice request: the client initiates a new request to request the slice document of pages 6-10; server response: the server generates the slice document of pages 6-10 according to the slice process introduced in step 3 and returns it to the client; repeated loading: after the client receives the slice document, it updates the cache again according to the preloading method of step 4; output data: slice document (pages 6-10), load page 6 and preload page 7, and recycle page 4 resources (if page 4 has been loaded).
