[0002] In the process of managing files (documents, pictures, videos, and other files), the following situation is often encountered: one management system uses one file management platform (old file management platform) to manage file data. With the advancement of technology, another management system uses another file management platform (new file management platform) to manage file data. When migrating file data in the old management system to the new file management platform one by one based on actual needs, the application system still needs to continuously obtain the corresponding files from the file management platform during this period. However, since some files have been migrated to the new file management platform and some files have not yet been migrated to the file management platform, the application system cannot obtain the corresponding files in a timely and accurate manner. Summary of the invention

[0013] If the frequency is greater than the preset frequency threshold, the old index of the first file stored locally remains unchanged, and a corresponding lock mark is added, wherein the lock mark indicates that the old index of the first file will remain unchanged.

[0014] In combination with the previous embodiment, in some optional embodiments, after modifying the old index of the first file stored locally to the new index, the method further includes:

[0015] When the first file needs to be obtained next time, the first file is obtained from the new file management platform according to the new index of the first file stored locally.

[0016] In combination with the first aspect, in some optional implementations, after determining whether the index of the first file currently stored locally is an old index, the method further includes:

[0018] In conjunction with the first aspect, in some optional implementations, the determining whether a migration permission response has been sent in response to a data migration request sent by the new file management platform includes:

[0019] Determining whether a data migration request sent by the new file management platform has been received;

[0020] If the data migration request has been received, it is determined whether the corresponding migration permission response has been sent in response to the data migration request.

[0021] In combination with the previous embodiment, in some optional embodiments, after determining whether the data migration request sent by the new file management platform has been received, the method further includes:

[0022] If the data migration request has not been received, the first file is obtained from the old file management platform according to the index of the first file currently stored locally.

[0023] Optionally, in some optional implementations, after determining whether the corresponding migration permission response has been sent for the data migration request, the method further includes:

[0024] If the corresponding migration permission response has not been sent for the data migration request, the first file is obtained from the old file management platform according to the index of the first file currently stored locally.

[0045] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0046] like Figure 1 As shown, the present invention provides a file acquisition method, including: S100, S200, S300, S400 and S500;

[0047] S100, determining whether a migration permission response has been sent in response to a data migration request sent by a new file management platform;

[0048] The data migration request is a request to migrate the first file from the old file management platform to the new file management platform, and the migration permission response indicates that the new file management platform is allowed to migrate the first file from the old file management platform;

[0049] If a migration permission response has been sent, execute S200;

[0050] Optionally, the executor of the present invention can be any application system, and the files of the application system are managed by the file management platform. When the file management platform changes or when part of the files need to be migrated to other file management platforms, the files of the old file management platform need to be migrated to the new file management platform. Since the old file management platform manages the files of multiple application systems at the same time, the new file management platform needs to obtain permission from the corresponding application system before migrating the files. For example, the new file management platform can send a corresponding data migration request to the corresponding application system. After receiving the data migration request, the application system can make a migration permission response to agree that the new file management platform can migrate one or some files of the corresponding application system from the old file management platform. The present invention does not limit this.

[0051] Therefore, the execution subject of the present invention, i.e. the application system, can first determine whether a migration permission response has been sent when it needs to obtain a price inquiry. If it has been sent, it means that the files of the application system in the old file management system may have been migrated to the new file management platform, so it is necessary to further determine whether they have been migrated to the new file management platform.

[0052] S200, determining whether the index of the first file currently stored locally is an old index;

[0053] If the index of the first file currently stored locally is an old index, execute S300;

[0054] Optionally, the present invention can modify the index of the corresponding file currently stored in the application system to a new index after the file may have been migrated to the new file management platform. The new index is the index generated corresponding to the file migration to the new file management platform, and the application system can quickly obtain the corresponding file from the new file management platform through the new index. Since the naming rules used by the old index and the new index are different, the old index and the new index are not universal in the new file management platform and the old file management platform, so the present invention can further determine whether the index of the first file currently stored locally is an old index;

[0055] Optionally, if the index of the first file currently stored locally is an old index, it does not mean that the first file has not been migrated to the new file management platform. Because after the file is migrated to the new file management platform, the application system can determine whether to modify the old index to the new index according to the actual situation. Therefore, the fact that the index of the first file currently stored locally is an old index does not mean that the file has not been migrated to the new file management platform.

[0056] S300, querying whether a new index corresponding to the old index is recorded in the new file management platform;

[0057] If the new index is recorded in the new file management platform, S400 is executed; if the new index is not recorded in the new file management platform, S500 is executed;

[0058] Optionally, after the new file management platform migrates the corresponding files, it will definitely generate a corresponding new index. Moreover, in order to avoid the situation where each application system cannot index the first file according to the old index, the old index and the corresponding new index will be saved in the new file management platform. Therefore, the application system can query whether there is a new index corresponding to the old index recorded in the new file management platform.

[0059] Optionally, if a new index corresponding to the old index is recorded in the new file management platform, it means that the first file has been migrated to the new file management platform, so the first file can be obtained from the new file management platform; if the new index corresponding to the old index is not recorded in the new file management platform, it means that the first file has not been migrated to the new file management platform, so the first file can be obtained from the old file management platform;

[0060] S400, obtaining a first file from a new file management platform according to a new index;

[0061] S500: Obtain a first file from an old file management platform according to an old index.

[0062] Optionally, according to the one-to-one correspondence between the index and the file, the corresponding file can be directly indexed according to the index, and the present invention does not limit the method of obtaining the file according to the index.

[0063] like Figure 2 As shown, combined Figure 1 In the illustrated embodiment, in some optional embodiments, after S400, the method further includes: S600, S700 and S800;

[0064] S600, determining whether the frequency of acquiring the first file is greater than a preset frequency threshold;

[0065] If the frequency is greater than the preset frequency threshold, execute S700; if the frequency is greater than the preset frequency threshold, execute S800;

[0066] As mentioned above, after the file is migrated to the new file management platform, the application system can determine whether it needs to change the index of the corresponding file stored locally to the new index based on the actual situation. Generally speaking, for files that need to be frequently called from the file management platform, the corresponding index stored locally in the application system can be modified to the new index to improve the efficiency of the application system in obtaining the corresponding file; for files that are not frequently called from the file management platform, the corresponding index stored locally in the application system can be left unchanged and continue to be the old index, thereby avoiding the need to modify the locally stored index every time a file migration occurs, and avoiding the situation of frequently modifying the local storage.

[0067] S700, modifying an old index of a first file stored locally into a new index;

[0068] S800: keep the old index of the first file stored locally unchanged, and add a corresponding lock mark;

[0069] The lock mark indicates that the old index of the first file will remain unchanged.

[0070] Optionally, as mentioned above, for files that are not frequently called from the file management platform, there is no need to modify the index stored locally in the application system. In order to avoid repeated judgment next time, the present invention can directly lock the old index of the first file and not allow it to be modified, that is, add a corresponding lock mark, so that the index can be directly determined to be unnecessary to be modified based on the lock mark next time, without having to judge again by frequency, thereby improving the use efficiency of the present invention.

[0071] like Figure 3 As shown, combined with Figure 2 In the illustrated embodiment, in some optional embodiments, after S700, the method further includes: S900;

[0072] S900: When the first file needs to be obtained next time, the first file is obtained from the new file management platform according to the new index of the first file stored locally.

[0073] As described above, when the index stored in the application system is modified to a new index, when the first file needs to be obtained next time, the first file can be directly obtained from the new file management platform based on the new index without making other judgments, thereby improving the efficiency of the present invention.

[0074] like Figure 4 As shown, combined Figure 1 In the embodiment shown, in some optional embodiments, after S200, the method further includes: S210;

[0075] S210: If the index of the first file currently stored locally is not an old index, obtain the first file from the new file management platform according to the index of the first file currently stored locally.

[0076] Optionally, if the index of the first file currently stored locally is not an old index, it means that it is a new index, so the first file can be obtained from the new file management platform.

[0077] like Figure 5 As shown, combined Figure 1 In the embodiment shown, in some optional embodiments, the S100 includes: S110 and S111;

[0078] S110, determining whether a data migration request sent by a new file management platform has been received;

[0079] If a data migration request has been received, execute S111;

[0080] As mentioned above, before the new file management platform performs file migration, it needs to obtain the consent of the corresponding application system. Therefore, the new file management platform can send a corresponding data migration request to the application system. From the perspective of the application system, when it needs to obtain the first file, the application system needs to determine whether it has agreed to the data migration request of the new file management platform, so it can first determine whether it has received the data migration request sent by the new file management platform;

[0081] If you have received a data migration request sent by the new file management platform, it means that you may have agreed to the request, so you need to further determine whether you have agreed to the request.

[0082] S111 : Determine whether a corresponding migration permission response has been sent in response to the data migration request.

[0083] Optionally, if a corresponding migration permission response has been sent in response to a data migration request, it means that the new file management platform has been agreed to perform file migration.

[0084] like Figure 6 As shown, combined with Figure 5 In the illustrated embodiment, in some optional embodiments, after S110, the method further includes: S112;

[0085] If no data migration request has been received, execute S112;

[0086] S112: Obtain the first file from the old file management platform according to the index of the first file currently stored locally.

[0087] Optionally, if no data migration request has been received, it means that the new file management platform has never initiated a file migration request for the files of the application system stored in the old file management platform. In this case, the first file can be directly obtained from the old file management platform based on the index of the first file currently stored locally.

[0088] like Figure 7 As shown, combined with Figure 5 In the illustrated embodiment, after S111, the method further includes: S113;

[0089] If no corresponding migration permission response has been sent for the data migration request, executing S113;
