the file operation request input here may include, but is not limited to, an addition request, a deletion request, a modification request, and a query request, and the specific content of the file operation request is not limited in the present application;
optionally, before receiving the file operation request input by the user, the login request input by the user may be received, the identity of the user is verified according to the login request, and the file operation request input by the user is allowed to be received only after the user is verified without errors, so as to improve the security of the system
S102: determining identity information of a user, and selecting an authority file set corresponding to the identity information according to a preset authority table;
the method comprises the following steps of selecting an authority file set corresponding to identity information according to a preset authority table, wherein the preset authority table is pre-stored with the corresponding relation between the identity information of each user and the authority file set, so that the files in the authority file set can be directly operated when the files are operated, the authority calculation of each file is not needed to complete screening, the screening efficiency of the authority files is improved, the operating efficiency of the files is improved, and the resource overhead of a server is reduced;
it should be noted that, this step may be executed only once for different file operation requests input by the same user.
Optionally, when a new user or a new file occurs, or a user logs off or deletes a file, or the like, which needs to modify the preset authority table, the modification of the corresponding relationship in the preset authority table may be further implemented by executing the following steps:
receiving a modification command;
and executing a modification command to modify the corresponding relation between the user permission in the preset permission list and the permission file set.
S103: and executing the operation corresponding to the file operation request on the corresponding file in the authority file set.
Optionally, after the corresponding file in the file directory is operated, a prompt message indicating that the operation is completed may be output to remind the user that the operation is completed, and a next operation may be performed.
Based on the technical scheme, the method for operating the file comprises the steps of determining the identity information of a user when receiving a file operation request input by the user, selecting the authority file set corresponding to the identity information according to the preset authority table, executing the operation corresponding to the file operation request on the corresponding file in the authority file set, so that the authority of each file does not need to be calculated in the whole file operation process, filtering the file without the authority, selecting the authority file set corresponding to the identity information according to the preset authority table, and operating the corresponding file in the authority file set, thereby improving the acquisition speed of the authority file, further improving the operation efficiency of the file, and reducing the resource overhead of a server.
For the previous embodiment, before the step S102 is executed to determine the identity information of the user and select the authority file set corresponding to the identity information according to the preset authority table, the steps shown in fig. 2 may also be executed, which is described below with reference to fig. 2.

The method specifically comprises the following steps:
s201: acquiring identity information of all users and user rights corresponding to the identity information;
s202: creating a corresponding authority file set according to each user authority;
optionally, to further improve the authority calculation performance, the creation of the authority file set may be implemented by constructing an authority tree, that is, the creation of the corresponding authority file set according to each user authority mentioned herein may specifically be:
acquiring tree-shaped storage structures of all files, and creating a corresponding authority tree according to the tree-shaped storage structures, wherein nodes of the authority tree comprise at least one of directories, subdirectories and files;
marking each node in the authority tree as an authority node or a non-authority node in sequence according to each user authority;

1) A node (23) without authority and child nodes, labeled as a non-authority node, with a query statement select from dms _ folder where folder _ parent folder id = 2and folder_id not in (23);
2) Nodes (22) which have no authority and have child nodes, and all the child nodes have no authority are marked as non-authority nodes;
3) An authorized node (24) marked as an authorized node;
4) The node (21) which has no authority and has child nodes, and the child nodes have authority is marked as non-authority nodes;
