[0045] After research, it was found that user permissions are the user's rights, that is, after an account logs in, some functions can be used, and some functions cannot be used. These are the permissions set by the administrator. Only users who meet the permissions can access the corresponding files.

[0046] When judging user permissions, the prior art will access the file permissions of all files through the command line, and then match the user permissions of the user with the file permissions of each file to determine the target files that the user can access. However, when there are a large number of files (especially hundreds, thousands or even millions of files) in the root directory that the user needs to view, it will take a lot of time to obtain the file permissions, which will affect the response speed of user access and bring inconvenience to the user.

[0047] In order to solve the above problems, in an embodiment of the present application, a user's access request is received; based on the user information, the target file corresponding to the user is obtained through the kernel function; and the obtained target file is displayed on the display interface in the form of a file list. The present application transmits the user information to the kernel function, accesses the file extension permissions of the file through the kernel function, and then filters out the files to which the user has access rights based on the file extension permissions and displays them. In this way, the target files can be filtered by accessing the file extension permissions through the kernel function, which can reduce the reading time of the file extension permissions, and further reduce the screening time of the target files, thereby improving the response time of user access and bringing convenience to users.

[0048] The application content is further explained below through the description of embodiments in conjunction with the accompanying drawings.

[0049] This embodiment provides a file list display method, such as Figure 1 As shown, the method includes:

[0050] S10. Receive an access request from a user, wherein the access request includes user information.

[0051] Specifically, the user's access request is a file access request that the user needs to access in the file system. The access request contains user information, which is used as a user identification so as to determine the target file to which the user has access rights based on the user information. For example, the user information can be a user authority identification, a user name, or a user signature, etc. The access request can be sent remotely by a user terminal device, or can be automatically processed based on a user login operation, or can be formed based on an access operation triggered by a user (such as a preset mode case or input of a preset mode instruction, etc.).

[0052] S20. Based on the user information, obtain the target file corresponding to the user through the kernel function.

[0053] Specifically, the kernel function is used to access the file extension permissions in the file system, wherein the file extension permissions include the user ID to which the file belongs. In other words, the file extension permissions include the user ID that has the permission to operate the file. To this end, after obtaining the user information, the file extension permissions of the file can be accessed through the kernel function to determine the target file corresponding to the user, wherein the target file corresponding to the user refers to the file to which the user has access rights, that is, the user can operate on the target file, for example, can perform read operations and / or write operations on the target file, etc.

[0054] For example, Figure 2 As shown, the method of obtaining the target file corresponding to the user through the kernel function based on the user information specifically includes:

[0055] S21, determining a root target address corresponding to the access request based on user information;

[0056] S22, transmitting the user information and the root target address to the kernel function through a preset access interface;

[0057] S23. Access the file extension permission of the file under the root target address through the kernel function to determine the target file to which the user information has access permission based on the file extension permission.

[0058] Specifically, the preset access interface is pre-configured and used to call the kernel function, that is, the access interface of the kernel function is pre-configured. After obtaining the user information, the preset access interface can be accessed to transmit the user information and the root target address to the kernel function through the preset access interface, and the file extension permissions of all files under the root directory corresponding to the user information and the root directory address are matched with the user information through the kernel function to filter out the target files that the user information has access rights to. Among them, the target address can be specified by the user, or it can be automatically obtained when the access request is formed (for example, if an access request is triggered for a folder, then the file address corresponding to the file is the root target address corresponding to the access request).

[0059] Of course, in actual applications, the access request may also carry a root target address, in which case the storage address of the file system is used as the root target address, that is, target files to which the user information has access rights are screened from all files included in the file system.

[0060] Furthermore, after obtaining the root target address and user information, the root target address and user information can be used as input information of the preset access interface, so as to pass the root target address and user information to the kernel function through the preset access interface, and then the kernel function calls the file extension permission used as the system information, and based on the user information, the called file extension permission is screened to select the target file to which the user information has access rights. Among them, in order to maximize the screening speed of the target file, the preset access interface is encapsulated in C language, and accessing the kernel function through the C language interface can further improve the access speed of the kernel function, and thus can further improve the verification efficiency of the file permissions.

[0061] It should be noted that, since the kernel function is a function for accessing system information, it is necessary to save the file extension permissions in the file system as system information. That is to say, whenever a new file appears in the file system, the file extension permissions of the new file will be set as system information, so that the file extension permissions of the new file can be accessed through the kernel function. In the embodiment of the present application, by configuring the file extension permissions as system information, and then when it is necessary to read the file extension permissions, the kernel function can be called through the preset access interface encapsulated in C language, and the file extension permissions are accessed through the kernel function and the target files that the user has access rights are screened out, thereby realizing rapid verification of user permissions, thereby improving the display efficiency of the target files.

[0062] S30: Display the acquired target files in the form of a file list on the display interface.

[0063] Specifically, displaying the acquired target files in the form of a file list on the display interface refers to displaying the file attribute information of the target files in the form of a file list on the display interface, wherein the file attribute information is obtained by reading the attribute information of the target files after the target files are screened. That is, after the target files with user permissions are screened through user permission verification, the file attribute information of each target file is read, and then the file attribute information is displayed in the form of a file list on the display interface, so that the user can obtain the file information of the target files.

[0064] When the target files are displayed on the display interface in the form of a file list, it can be realized by a step-by-step display method. Specifically, the number of target files that can be displayed on a display page of the display interface is fixed. Therefore, when the target files are displayed on the display interface in the form of a file list, the target files of the target file data can be displayed on the display interface first, and then other target files can be used as cache pages. When a page turning operation is received, the cache page corresponding to the page turning operation is determined, and the cache page is displayed on the display interface. In this way, the page turning operation can be responded to quickly to avoid the problem of waiting for display.

[0065] Furthermore, since the target file can be displayed on the display interface in a page-by-page manner, when reading the file attribute information of the target file, it can also be read in an asynchronous manner. Specifically, a certain amount of file attribute information can be read through the access thread, and the read file attribute information can be cached in a preset cache area, and then a display page in the form of a file list can be constructed based on the file attribute information in the preset cache area, and the display page can be displayed on the display interface, wherein the file attribute information in the preset cache area that is not included in the display page will be constructed into a cache page to quickly respond to the page turning operation.

[0066] Based on this, the file list display method is characterized in that the step of displaying the acquired target files in the form of a file list on the display interface specifically includes:

[0067] Creating a number of access threads, and obtaining attribute information of a target file in an asynchronous manner through the number of access threads;

[0068] The acquired attribute information is displayed on the display interface in the form of a file list.

[0069] Specifically, each of the access threads is used to obtain the attribute information of the target file, that is, the attribute information of the target file is obtained in parallel through the access threads. Among them, the number of the access threads can be constructed according to the number of files of the target file. For example, the number of the access threads can be one-N of the number of files. N can be preset or determined according to the number of files. For example, when the number of files is less than the first threshold, N can be a first positive integer. When the number of files is greater than or equal to the first threshold and less than the second threshold, N can be a second positive integer. When the number of files is greater than or equal to the second threshold, N can be a third positive integer, wherein the first positive integer is less than the second positive integer, and the second positive integer is less than the third positive integer. In addition, when the number of threads determined based on the number of files is greater than the maximum number of parallel threads allowed by the system, the maximum number of parallel threads is used as the number of threads of the constructed access threads. In addition, after accessing the attribute information through the access thread, the attribute information can be cached in a preset cache area, and then the attribute information of the target file can be obtained through the access information, thereby realizing asynchronous caching of the attribute information.

[0070] The present application obtains the attribute information of the target file by asynchronous caching, which can not only further improve the display speed of the file list, but also avoid the problem of failure to obtain some attribute information due to the access time limit of the preset access interface.

[0071] Furthermore, before obtaining the attribute information, all files under the root directory address can be sorted in the form of a file list, wherein the order is presented in the form of a directory structure tree; then the attribute information of the target files is read in sequence according to the position order of each target file in the directory structure tree, and then the read attribute information is cached in the form of a directory structure tree in a preset cache area, and the position of the attribute information of each target file in the cached directory structure tree is matched with the position of the target file in the directory structure tree, and finally the display pages are divided according to the order of the directory structure tree from front to back, and the display page located at the front is displayed on the display interface, and the other display pages are used as cache pages. In addition, when the attribute information is obtained and cached in the form of a directory structure tree in the cache, when the cached directory structure tree includes the attribute information required for a display page (the first attribute information of the display page is the first attribute information from the directory structure tree, and contains continuous attribute information in the directory structure tree) in the order from front to back, the display page is displayed on the display interface to improve display efficiency.

[0072] Of course, in actual application, it is possible to start from the first position of the target structure tree, include continuous attribute information that the target structure tree meets the requirements of a display page, form a display page in the form of a file list, and display the display page on the display interface, then receive the user's page scrolling operation, and update the attribute information on the display page in real time based on the scrolling operation (i.e., determine the position information of the attribute information above the display business in the target structure tree based on the scrolling operation, and then select the attribute information that meets the requirements of the display page with the position information as the starting position), so that the user can view the attribute information of the target file at any position in the target structure tree. In addition, when responding to the scrolling operation, if some attribute information that needs to be displayed is not obtained, a display page with the previous attribute information of the attribute information that has not been obtained as the last attribute information will be displayed, and when the attribute information that has not been obtained is obtained, the current display page will be updated to affect the scrolling operation. In this way, not only can the scrolling operation be responded to at the fastest speed, but also when the scrolling operation cannot be responded to, the attribute information required by the user can be displayed as much as possible.

[0073] In summary, the present embodiment provides a file list display method, the method comprising first sorting all files under the root directory address to form a directory structure tree, then reading the file extension permission as system information through a kernel function, and verifying the user permission through the file extension permission to obtain a target file with user permission; finally, reading the attribute information of the target file through a parallel thread, caching the read attribute information in a preset cache area, the attribute information obtained in the preset cache area is also stored in the form of a directory structure tree, and starting from the first position of the target structure tree, the target structure tree including continuous attribute information that meets the requirements of a display page is formed into a display page in the form of a file list, and the display page is displayed on the display interface, for the attribute information in the target structure tree that is displayed on the display page, starting from the attribute information located at the front of the displayed attribute information, the operation of forming a display page in the form of a file list that meets the requirements of a display page for the target structure tree including continuous attribute information is repeated until the target file located at the end of the target structure tree is located, wherein the display page that is not displayed on the display interface is used as a cached display page, and when the display page needs to be displayed, the cached display page is directly displayed on the display interface. This application uses kernel functions to call file extension permissions and verifies user permissions based on file extension permissions, thereby improving the verification speed of user permissions, especially for access to a large number of file systems. At the same time, after obtaining a target file with user permissions, this application reads the attribute information through parallel threads and displays the attribute information page by page in the form of a target structure tree. When part of the attribute information is obtained, it can be displayed to the user, and the user will not be aware of the attribute information that has not been obtained, thereby improving the display efficiency of the file list.
