[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0039] With the development of distributed storage, it has become common to use the NFS protocol to operate massive files. Without filtering functions, manual filtering is required when operating files, and accuracy cannot be guaranteed. Among existing network communication protocols, CIFS supports file filtering, but the CIFS protocol is mainly used in Windows systems and is not suitable for Linux systems.

[0040] To this end, this application provides a file filtering solution that can implement file filtering in various systems to reduce labor costs.

[0041] See also Figure 1 As shown, the embodiment of the present application discloses a file filtering method, including:

[0042] Step S11: obtaining the current filtering condition and the previous filtering condition in the service configuration file of the network file system.

[0043] In this embodiment, the NFS network file system is one of the current mainstream heterogeneous platform shared file systems, which allows computers in the network to share resources through the TCP (Transmission Control Protocol) / IP (Internet Protocol) network. It is mainly used to share directories and files in the UNIX environment. The working principle of NFS is to use a client / server architecture, consisting of a client program and a server program. In massive storage and distributed file and object storage, the NFS protocol has a wide range of applications. NFS operation words: Network file system operation words refer to a series of methods for operating files. Files can be in multiple states, so that users or processes can operate on files. The network file system calls the lib in ceph (distributed file system) through operation words to implement the functions corresponding to the operation words. CIFS is a communication protocol for network file sharing between Windows hosts. Lib is a computer file format, and there are two types of libs. One is a static library, such as the C-Runtime library. This type of lib contains function implementation code and is generally used in static linking. It adds the code in the lib to the target module file, where the target module can be an EXE (executable) or a DLL (Dynamic Link Library). Therefore, after linking, the lib file is useless. Another type of lib is used in conjunction with a DLL. It does not contain any code, but the code is in the DLL. This type of lib is used for statically calling the DLL, so it also serves as a link. Once the link is completed, the lib is no longer useful.

[0044] Step S12: adjusting the previous filtering condition based on the current filtering condition to obtain the current target filtering condition.

[0045] In this embodiment, it can be understood that if the current filtering condition is consistent with the previous filtering condition, then the previous filtering condition can be directly used as the current target filtering condition. If the current filtering condition is inconsistent with the previous filtering condition, then the condition in which there is a difference between the current filtering condition and the previous filtering condition, that is, the difference condition, is determined, and the difference condition is used to adjust the previous filtering condition to obtain the current target filtering condition. For example, the previous filtering condition 1 is to filter out files within a preset period, and the previous filtering condition 2 is to filter out files in a preset file library. Therefore, it can be inferred that the previous target file after filtering based on the previous filtering condition 1 and the previous filtering condition 2 is a file that is neither in the preset file library nor within the preset period. If the current filtering condition is only to filter out files within the preset period, then the determined difference condition is to filter out files in the preset file library, so the previous filtering condition 2 is deleted based on the difference condition, and only the previous filtering condition 1 is retained, and the previous filtering condition 1 is used as the current target filtering condition. In the network file system service configuration file, filter conditions can be dynamically modified and deleted without restarting the network file system service, ensuring normal business operations. When modifying, the linked list structure storing the filter conditions is updated. When deleting, the linked list structure storing the filter conditions is first removed from the linked list and then the memory is released. It is also possible to adjust only the specific position of a condition in the previous filter based on the difference condition. For example, if the previous filter condition is to filter out files not dated between March 5, 2019 and March 28, 2022, and the current filter condition is to filter out files not dated between March 5, 2019 and March 28, 2021, then you only need to modify "2022" in the previous filter condition to "2021" so that the previous filter condition filters out files not dated between March 5, 2019 and March 28, 2021, making the previous filter condition the current target filter condition. It should be noted that the current file is being filtered. When filtering the next file, the current target filtering condition needs to be updated to the previous filtering condition, and when filtering the next file, it needs to be updated to the current file filtering condition.

[0046] In this embodiment, when storing multiple previous filter conditions, if there are multiple previous filter conditions, the multiple previous filter conditions can be segmented using a preset segmentation condition; the segmented previous filter conditions are respectively stored in the corresponding linked list structure in the service configuration file, and the memory of the corresponding size is allocated to the segmented previous filter conditions. The service configuration file of the network file system supports setting multiple filter conditions, and the filter conditions can be separated by a preset segmentation character, such as " / ". The configured filter conditions are segmented using " / ", and each segmentation is stored in the linked list structure, which facilitates dynamic memory allocation.

[0047] Step S13: Mounting the client of the network file system to the server, so as to filter the current file using the network file system protocol and the current target filtering condition to obtain the target file.

[0048] In this embodiment, mounting the client of the network file system to the server so as to filter the current file using the network file system protocol and the current target filtering condition to obtain the target file specifically includes: mounting the client of the network file system to the server so as to determine the current file to be filtered using the network file system protocol and the current target filtering condition, and filtering the current file to be filtered from the current file to obtain the target file.

[0049] In this embodiment, after the client of the network file system is mounted on the server, operations such as creating directories or files are performed, and the linked list structure of the storage filter conditions is traversed in the process of triggering operation words in the network file system protocol, where the operation words may include mkdir (create directory), create (create file), remove (delete file or directory), rename (rename file), and readdir (display directory and files).

[0050] In this embodiment, after filtering the current file to be filtered from the current file, it also includes: generating preset prompt information corresponding to the current file to be filtered, and displaying the preset prompt information through a preset prompt interface. When the user searches for file 1, relevant information corresponding to file 1, such as the file name, can be entered in the preset search interface. If file 1 has been filtered out based on the current target filtering conditions, a preset prompt information corresponding to file 1 is generated. The preset prompt information can be "File 1 has been filtered based on the current target filtering conditions", and the preset prompt information is displayed through the preset prompt interface so that the user can perform corresponding processing based on the preset prompt information. It can be understood that the preset prompt information is also a kind of operation word error code.

[0051] It can be seen that the present application obtains the current filtering condition and the previous filtering condition in the service configuration file of the network file system; adjusts the previous filtering condition based on the current filtering condition to obtain the current target filtering condition; mounts the client of the network file system to the server, so as to filter the current file using the network file system protocol and the current target filtering condition to obtain the target file. It can be seen that the previous filtering condition is adjusted in the service configuration file of the network file system in each system to obtain the current target filtering condition, and the current file is filtered using the network file system protocol and the current target filtering condition to obtain the target file, thereby reducing the labor input cost and improving efficiency when operating files.

[0052] See also Figure 2 As shown, the embodiment of the present application discloses a specific file filtering method, including:

[0053] Step S21: obtaining the current filtering condition and the previous filtering condition in the service configuration file of the network file system.

[0054] In this embodiment, before obtaining the current filtering condition and the previous filtering condition in the service configuration file of the network file system, the method further includes: storing the previous filtering condition in the corresponding linked list structure in the service configuration file.

[0055] In this embodiment, storing the previous filter condition in the corresponding linked list structure in the service configuration file specifically includes: using a preset segmentation condition to segment a plurality of the previous filter conditions; storing the segmented previous filter conditions in the corresponding linked list structure in the service configuration file, and allocating a corresponding size of memory to the segmented previous filter conditions. The service configuration file of the network file system supports setting multiple filter conditions. The filter conditions can be segmented using a preset segmentation character, such as " / ". The wildcard "?" is used in the filter condition to represent an arbitrary character, and the wildcard "*" can represent an arbitrary string of characters. The configured filter condition is segmented using " / ", and each segmentation is performed, the filter condition is stored in the linked list structure, which facilitates dynamic allocation of memory size.

[0056] Step S22: Determine whether the current filtering condition is consistent with the previous filtering condition; if not, determine the difference between the current filtering condition and the previous filtering condition, and adjust the previous filtering condition based on the difference to obtain the current target filtering condition.

[0057] In this embodiment, the previous filtering condition is adjusted based on the difference condition to obtain the current target filtering condition, specifically including: determining whether the difference condition meets the preset condition; if so, removing the linked list structure used to store the corresponding previous filtering condition in the service configuration file, and releasing the corresponding memory. It can be understood that, for example, the previous filtering condition is only to filter out files that are not within the preset period, and the current filtering condition is two filtering conditions, namely current filtering condition 1: filter out files that are not within the preset period, and current filtering condition 2: filter out files that are not in the preset file library. It can be determined that the previous filtering condition is inconsistent with the current filtering condition, and it is determined that the difference condition is to filter out files that are not within the preset period. Then, the difference condition can be added to the corresponding position in the previous filtering condition, that is, the previous filtering condition is adjusted to obtain the current target filtering condition; the previous filtering condition can also be modified. For example, the previous filtering condition is to filter out files that are not between February 10, 2022 and February 15, 2022, and the current filtering condition is to filter out files that are not between February 10, 2022 and February 27, 2022. Then, you only need to modify the corresponding content in the previous filtering condition so that the previous filtering condition is to filter out files that are not between February 10, 2022 and February 27, 2022, and then make the previous filtering condition the current target filtering condition. It should be noted that the current file is being filtered. When filtering the next file, the current target filtering condition needs to be updated to the previous filtering condition, and when filtering the next file, it needs to be updated to the current file filtering condition.

[0058] Step S23: Mounting the client of the network file system to the server, so as to filter the current file using the network file system protocol and the current target filtering condition to obtain the target file.

[0059] In this embodiment, the current target filtering condition can be set not only to filter the current file, but also to filter the directory level in the current file, which is more detailed and specific.

[0060] It can be seen from this that in this application, if the current filtering file is inconsistent with the previous filtering file, the difference condition can be determined, and the previous filtering file can be adjusted based on the difference condition to obtain the current target filtering file. Therefore, there is no need to reset the complete current filtering file. It is only necessary to adjust the previous filtering file based on the difference file, which greatly reduces the workload of setting the filtering conditions, thereby improving the speed and efficiency of subsequent file filtering and reducing labor costs. Because the accuracy of manually set filtering conditions is low, reducing the manually set filtering conditions can further improve the accuracy of file filtering.

[0061] See also Figure 3As shown, the embodiment of the present application discloses a file filtering device, comprising:

[0062] Condition acquisition module 11, used to obtain the current filtering condition and the previous filtering condition in the service configuration file of the network file system;

[0063] A condition adjustment module 12, configured to adjust the previous filtering condition based on the current filtering condition to obtain a current target filtering condition;

[0064] The file filtering module 13 is used to mount the client of the network file system to the server, so as to filter the current file using the network file system protocol and the current target filtering condition to obtain the target file.

[0065] Among them, the condition adjustment module 12 is specifically used to: if the current filtering condition is consistent with the previous filtering condition, then the previous filtering condition can be directly used as the current target filtering condition; if the current filtering condition is inconsistent with the previous filtering condition, then the condition in which there is a difference between the current filtering condition and the previous filtering condition, that is, the difference condition, is determined, and the difference condition is used to adjust the previous filtering condition to obtain the current target filtering condition. For example, the previous filtering condition 1 is to filter out files within a preset period, and the previous filtering condition 2 is to filter out files in a preset file library. Therefore, it can be inferred that the previous target file after filtering based on the previous filtering condition 1 and the previous filtering condition 2 is a file that is neither in the preset file library nor within the preset period. If the current filtering condition is only to filter out files within the preset period, then the determined difference condition is to filter out files in the preset file library, so the previous filtering condition 2 is deleted based on the difference condition, and only the previous filtering condition 1 is retained, and the previous filtering condition 1 is used as the current target filtering condition. You can also adjust only the specific position of a certain condition in the previous filter condition based on the difference condition. For example, if the previous filter condition was to filter out files not dated between March 5, 2019 and March 28, 2022, and the current filter condition is to filter out files not dated between March 5, 2019 and March 28, 2021, then you only need to change "2022" in the previous filter condition to "2021" so that the previous filter condition filters out files not dated between March 5, 2019 and March 28, 2021, and thus the previous filter condition becomes the current target filter condition. It should be noted that the current target filter condition is currently being filtered, so when filtering the next file, the current target filter condition needs to be updated to the previous filter condition, and when filtering the next file, it needs to be updated to the current file filter.

[0066] The condition adjustment module 12 is specifically used to: determine whether the difference condition meets the preset condition; if so, remove the linked list structure used to store the corresponding previous filtering condition in the service configuration file, and release the corresponding memory. It can be understood that, for example, the previous filtering condition is only to filter out files that are not within the preset period, and the current filtering condition is two filtering conditions, namely current filtering condition 1: filter out files that are not within the preset period, and current filtering condition 2: filter out files that are not in the preset file library. It can be determined that the previous filtering condition is inconsistent with the current filtering condition, and it is determined that the difference condition is to filter out files that are not within the preset period. Then, the difference condition can be added to the corresponding position in the previous filtering condition, that is, the previous filtering condition is adjusted to obtain the current target filtering condition; the previous filtering condition can also be modified. For example, the previous filtering condition is to filter out files that are not between February 10, 2022 and February 15, 2022, and the current filtering condition is to filter out files that are not between February 10, 2022 and February 27, 2022. Then, you only need to modify the corresponding content in the previous filtering condition so that the previous filtering condition is to filter out files that are not between February 10, 2022 and February 27, 2022, and then make the previous filtering condition the current target filtering condition. It should be noted that the current file is being filtered. When filtering the next file, the current target filtering condition needs to be updated to the previous filtering condition, and when filtering the next file, it needs to be updated to the current file filtering condition.

[0067] The file filtering device is specifically configured to store the last filtering condition in the corresponding linked list structure in the service configuration file.

[0068] The file filtering device is specifically configured to: split a plurality of the previous filtering conditions using a preset splitting condition; store the splitted previous filtering conditions in the corresponding linked list structure in the service configuration file; and allocate a corresponding amount of memory to the splitted previous filtering conditions. The service configuration file of the network file system supports setting multiple filtering conditions, and the filtering conditions can be separated by a preset separator character, such as " / ". The configured filtering conditions are separated by " / ", and each filter condition is stored in the linked list structure after each split, thereby facilitating dynamic memory allocation.

[0069] The file filtering device is specifically used to: generate preset prompt information corresponding to the current file to be filtered, and display the preset prompt information through a preset prompt interface. When a user searches for file 1, he can enter relevant information corresponding to file 1, such as the file name, in the preset search interface. If file 1 has been filtered out based on the current target filtering conditions, a preset prompt information corresponding to file 1 is generated. The preset prompt information can be "File 1 has been filtered based on the current target filtering conditions", and the preset prompt information is displayed through the preset prompt interface so that the user can perform corresponding processing based on the preset prompt information. It can be understood that the preset prompt information is also a kind of operation word error code.

[0070] It can be seen that the present application obtains the current filtering condition and the previous filtering condition in the service configuration file of the network file system; adjusts the previous filtering condition based on the current filtering condition to obtain the current target filtering condition; mounts the client of the network file system to the server, so as to filter the current file using the network file system protocol and the current target filtering condition to obtain the target file. It can be seen that the previous filtering condition is adjusted in the service configuration file of the network file system in each system to obtain the current target filtering condition, and the current file is filtered using the network file system protocol and the current target filtering condition to obtain the target file, thereby reducing the labor input cost and improving efficiency when operating files.

[0071] In some specific embodiments, the condition adjustment module 12 includes:

[0072] A first judging unit, configured to judge whether the current filtering condition is consistent with the previous filtering condition;

[0073] The filtering condition obtaining unit is configured to determine a difference between the current filtering condition and the previous filtering condition if there is any inconsistency, and adjust the previous filtering condition based on the difference to obtain the current target filtering condition.

[0074] In some specific embodiments, the condition adjustment module 12 includes:

[0075] A second judging unit, configured to judge whether the difference condition satisfies a preset condition;

[0076] The removing unit is used to remove the linked list structure for storing the corresponding previous filtering condition in the service configuration file if the condition is met, and release the corresponding memory.

[0083] The target file acquisition unit is used to mount the client of the network file system to the server, so as to determine the current file to be filtered by using the network file system protocol and the current target filtering condition, and filter the current file to be filtered from the current file to obtain the target file.
