[0058] The embodiment of the present invention provides a file asynchronous collaboration method, referring to Figure 2 , Figure 2 The figure is a flowchart of an embodiment of the asynchronous file collaboration method of the present invention.

[0064] S500: storing the target uploaded file as a new target collaborative file, and using the new version information as the first version information of the new target collaborative file.

[0065] It should be noted that in some scenarios, there is a situation where conflicts may occur when multiple users operate files remotely in the system, and when faced with erroneous file modifications, the file version cannot be traced, which reduces the security of file data in the asynchronous collaboration process of multiple users. In order to solve the above problems, this embodiment determines the target collaborative file and sends it to the user terminal for user use when receiving a file download request from the user terminal. When receiving the target uploaded file uploaded by the user terminal, it determines whether the target collaborative file and the target uploaded file are consistent based on the integrity verification value of the target collaborative file and the target uploaded file, and determines whether the versions of the current target collaborative file and the target uploaded file are consistent, thereby generating new version information of the target uploaded file or prompting version conflicts, and realizing the storage of new version information and new target collaborative files. Therefore, when faced with multiple users modifying files remotely, the present invention solves file modification conflicts through operations such as integrity verification values, file historical versions, and system prompts, avoids file inconsistencies, retains historical versions of file modifications, realizes the traceability of file versions, and ensures the security of file data.

[0066] In a preferred embodiment, upon receiving a file download request from a user terminal, the step of determining a target collaborative file specifically includes:

[0067] S110: receiving a file download request from a user terminal; wherein the file download request includes a user identifier of the user terminal and a file identifier of a target collaborative file;

[0068] S120: traverse the file storage server using the file identifier of the target collaborative file to determine the target collaborative file corresponding to the file download request.

[0069] On this basis, the step of calculating a first integrity verification value of the target collaborative file, storing the first integrity verification value and sending the target collaborative file to the user terminal specifically includes:

[0070] S210: Calculate a first MD5 value of the target collaborative file, and store the first MD5 value;

[0071] S220: Accessing a collaborative file permission list corresponding to the user identification of the user terminal, and judging whether the user terminal has access rights to the target collaborative file based on the collaborative file permission list;

[0072] S230: If yes, send the target collaboration file to the user terminal.

[0073] In this embodiment, the file identifier of the target collaborative file in the file download request of the user terminal is extracted, and the storage location of the target collaborative file is determined in the file storage server using the file identifier of the target collaborative file. Then, based on the user identifier of the user terminal in the file download request, a permission comparison is performed to determine whether the user terminal has access rights to the target collaborative file. If so, the first MD5 value of the target collaborative file is calculated and saved before being sent to the user terminal.

[0074] In a preferred embodiment, when receiving a target uploaded file corresponding to the target collaborative file uploaded by a user terminal, calculating a second integrity verification value of the target uploaded file, and judging whether the target uploaded file is consistent with the target collaborative file based on the first integrity verification value and the second integrity verification value, the step specifically includes:

[0075] S310: when receiving a target uploaded file uploaded by a user terminal, extracting a file identifier of the target uploaded file, determining whether the file identifiers of the target uploaded file and the target collaborative file are the same, and if so, determining the target uploaded file as a corresponding file of the target collaborative file;

[0076] S320: Calculate the second MD5 value of the target uploaded file, and determine whether the target uploaded file is consistent with the target collaborative file based on the first MD5 value and the second MD5 value.

[0077] Furthermore, the step of obtaining the first version information of the target collaborative file stored in the file storage server and the second version information of the target uploaded file in the user terminal specifically includes:

[0078] S330: matching the first version information of the target collaborative file before it is sent to the user terminal in a comparison table of the target collaborative file identification information and version information stored in the file storage server according to the target collaborative file identification information;

[0079] S340: upon receiving a target uploaded file corresponding to the target collaborative file uploaded by the user terminal, obtaining second version information of the target collaborative file corresponding to the target uploaded file uploaded by the user terminal and generated after being modified by the user terminal;

[0080] The second version information is configured as version information obtained after updating the first version information according to preset rules, and the preset rules include modification duration or modification number of people.

[0081] In this embodiment, by comparing the second MD5 value of the target uploaded file with the first MD5 value calculated before the target collaborative file is sent, it is determined whether the target uploaded file is consistent with the target collaborative file. After that, the first version information of the target collaborative file stored in the file storage server and the second version information of the target uploaded file in the user terminal are obtained. Subsequently, the first version information and the second version information can be used to determine whether other people have modified the stored target collaborative file, that is, whether the target collaborative file can be replaced with the target uploaded file.

[0082] In a preferred embodiment, based on the first version information and the second version information, it is determined whether the target collaborative file and the target uploaded file are different versions, and if so, a version conflict warning is generated; if not, a new version information step of the target uploaded file is generated according to the first version information and the second version information, specifically including:

[0083] S410: extracting first text content corresponding to the first version information and second text content corresponding to the second version information, and judging whether the target collaborative file and the target uploaded file are different versions based on the similarity between the first text content and the second text content;

[0084] S420: If yes, generate a version conflict warning; if no, generate new version information of the target uploaded file according to the first version information and the second version information;

[0085] The new version information includes version information composed of first version information representing an original version and second version information representing a modified version.

[0086] On this basis, the target uploaded file is stored as a new target collaborative file, and the new version information is used as the first version information step of the new target collaborative file, specifically including:

[0087] S510: storing the target uploaded file as a new target collaborative file, and using the new version information as the first version information of the new target collaborative file;

[0088] S520: Perform a file information persistence operation on the new target collaborative file; wherein the file information includes at least one of a name, a size, a type, a version information, and a modification time.

[0089] In this embodiment, the target collaborative file and the target uploaded file are judged to be consistent according to their integrity verification values, and the versions of the current target collaborative file and the target uploaded file are determined to be consistent, thereby generating new version information of the target uploaded file or prompting version conflicts, and realizing the storage of new version information and new target collaborative files. Therefore, when facing multiple users modifying files remotely, the present invention solves file modification conflicts through operations such as integrity verification values, file historical versions, and system prompts, avoids file inconsistencies, retains historical versions of file modifications, realizes the traceability of file versions, and ensures the security of file data.
