[0028] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0030] It should be noted that the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved in the technical solution disclosed herein are all carried out with the consent of the user, and all comply with the provisions of relevant laws and regulations, and do not violate public order and good morals.

[0031] The file storage method of this disclosure is described below with reference to the accompanying drawings.

[0032] Figure 1 This is a schematic flowchart illustrating the file storage method according to the first embodiment of this disclosure. It should be noted that the file storage method implemented in this disclosure can be applied to application servers.

[0033] like Figure 1 As shown, the method for storing this file may include the following steps:

[0034] Step 101: Receive a file upload request sent by the application client.

[0035] The file upload request includes the file to be stored.

[0036] In this embodiment of the disclosure, when relevant business personnel handle related business, they need to upload business-related documents (such as scanned copies of ID cards). The business personnel perform the upload operation on the application client to upload the files. Therefore, in response to the upload operation, the application client can send a file upload request to the application server. The file upload request may include the file to be stored.

[0037] The file types to be stored can be images, videos, document files (such as PDF files and Word files), and text files (txt files), etc.

[0038] Step 102: Determine the first file type to which the file to be stored belongs, and determine the storage directory of the file to be stored in the application server based on the first file type.

[0039] In this embodiment of the disclosure, different types of files to be stored are stored in different directories. For example, image files are stored in directory A, video files are stored in directory B, text files are stored in directory C, and document files are stored in directory D.

[0040] As an example, file naming rules can be pre-set, that is, different types of files use different naming rules. For example, image files are named using a set number, such as a scanned copy of an ID card, which is named using the ID card number; and video files are named using the time and video identifier.

[0041] Therefore, the first file type of the file to be stored can be determined according to the naming rules or file extension of the file to be stored. Then, the storage directory of the file to be stored in the application server can be determined according to the first file type. It should be noted that the storage directory can be a disk directory in the application server, such as H:\work\.

[0042] Step 103: Respond to the file upload request and determine whether the primary storage server and / or secondary storage server are available.

[0043] Furthermore, in response to the file upload request, a server self-check procedure is executed to obtain the primary storage server and the secondary storage server to determine whether the primary storage server and / or the secondary storage server are in an available state.

[0044] It should be noted that the application server can record the status of the primary and secondary storage servers in the logs and send the logs to the client. Thus, relevant personnel can check the status of the primary and secondary storage servers based on the logs, and promptly debug or repair the server when the primary or secondary storage server experiences a failure.

[0045] Step 104: If at least one of the primary storage server and the secondary storage server is available, send a file storage request to at least one server.

[0046] The file storage request includes the file to be stored and the directory to be stored. The file storage request is used by at least one server to store the file to be stored in a first storage directory, which is a disk directory that the directory to be stored is allowed to link to.

[0047] It is important to understand that the storage directory in the application server has a mapping relationship with the target in the primary storage server and the secondary storage server. The primary storage server or the secondary storage server can determine the directory where the file to be stored needs to be stored based on the directory to be stored, which is the first storage directory. The first storage directory is the disk directory that the directory to be stored can link to.

[0048] Therefore, if at least one of the primary storage server and the secondary storage server is available, the application server sends a file storage request to the primary storage server. The primary storage server can determine the first storage directory based on the storage directory in the file storage request and store the file to be stored in the first storage directory.

[0049] It should be noted that the first storage directory is the disk directory that the storage directory is allowed to link to. Storing the files to be stored in the disk files makes it easier to quickly find the target files among multiple storage files during file download, thus improving download speed.

[0050] In summary, by receiving file upload requests from application clients, including the file to be stored; determining the first file type of the file to be stored; determining the storage directory of the file on the application server based on the first file type; responding to the file upload request and determining whether the primary storage server and / or secondary storage server are available; and if at least one of the primary and secondary storage servers is available, sending a file storage request to at least one server, including the file to be stored and the storage directory, the file storage request is used by at least one server to store the file to be stored in the first storage directory, which is a disk directory that the storage directory is allowed to link to. Thus, when at least one of the primary and secondary storage servers is available, storing the file to be stored in the first storage directory of at least one server reduces the storage pressure on the application server, improves the operating speed of the application server, and thereby improves the efficiency of related business processing.

[0051] To clearly illustrate how the above embodiments determine whether the primary storage server and / or secondary storage server are in an available state, this disclosure proposes another file storage method.

[0052] Figure 2 This is a schematic flowchart illustrating the file storage method according to the second embodiment of this disclosure. It should be noted that the file storage method implemented in this disclosure can be applied to application servers.

[0053] Step 201: Receive a file upload request sent by the application client.

[0054] The file upload request includes the file to be stored.

[0055] Step 202: Determine the first file type to which the file to be stored belongs, and determine the storage directory of the file to be stored in the application server based on the first file type.

[0056] Step 203: Respond to the file upload request by sending at least one status verification request to both the primary storage server and the secondary storage server.

[0057] As an example, when the application server responds to a file upload request, it simultaneously sends at least one status verification request to both the primary and secondary storage servers, i.e., sends at least one status verification request to attempt to wake up both the primary and secondary storage servers.

[0058] Step 204: In response to receiving a status verification response sent by the primary storage server in response to at least one status verification request, determine that the primary storage server is in an available state.

[0059] In this embodiment of the disclosure, upon receiving a status verification response sent by the primary storage server in response to at least one status request, it can be determined that the primary storage server is in an available state.

[0060] Step 205: In response to receiving a status verification response sent by the storage server in response to at least one status verification request, determine that the storage server is in an available state.

[0061] In this embodiment of the disclosure, upon receiving a status verification response sent by the storage server in response to at least one status verification request, it can be determined that the storage server is in an available state.

[0062] Step 206: If at least one of the primary storage server and the secondary storage server is available, send a file storage request to at least one server.

[0063] The file storage request includes the file to be stored and the directory to be stored. The file storage request is used by at least one server to store the file to be stored in a first storage directory, which is a disk directory that the directory to be stored is allowed to link to.

[0064] As an example, when the primary storage server is available, a file storage request is sent to the primary storage server. This file storage request is used to store the file to be stored in the first storage directory of the primary storage server. Then, it is determined whether the secondary storage server is available. If the secondary storage server is available, a file synchronization request is sent to the secondary storage server. This file synchronization request includes the file to be stored and the first storage directory, and is used by the secondary storage server to synchronize the file to be stored to the first storage directory. Conversely, if the primary storage server is unavailable and the secondary storage server is available, a file storage request is sent to the secondary storage server. This file storage request is used to store the file to be stored in the first storage directory of the secondary storage server.

[0065] In other words, when the primary storage server is available (e.g., both the primary and secondary storage servers are available), or when the primary storage server is available but the secondary storage server is unavailable, a file storage request is sent to the primary storage server. The primary storage server then stores the file to be stored in its own first storage directory. Additionally, the primary storage server can determine whether the secondary storage server is available. If the secondary storage server is available, the primary storage server sends a file synchronization request to it. This file synchronization request includes the file to be stored and the first storage directory, and is used by the secondary storage server to synchronize the file to be stored to the first storage directory. Conversely, if the primary storage server is unavailable but the secondary storage server is available, the primary storage server sends a file storage request to the secondary storage server, and the secondary storage server stores the file to be stored in its own first storage directory.

[0066] It should be noted that the main storage server can receive file storage requests from multiple application servers simultaneously. The main storage server can store the files to be stored from multiple application servers to the corresponding storage directory, enabling file aggregation, merging, and file sharing.

[0067] Furthermore, to prevent files from being unstorable when both the primary and secondary storage servers are unavailable, the file to be stored is stored in the specified directory if at least one of the primary and secondary storage servers is available. Once at least one of the primary and secondary storage servers becomes available again, the file storage request is resent to at least one server to ensure the file is stored on that server. For example, after both the primary and secondary storage servers are unavailable, the application server can send at least one status verification request to both servers at set intervals. Upon receiving a status verification response from the primary storage server in response to at least one status verification request, the primary storage server is confirmed to be available again. Similarly, upon receiving a status verification response from the secondary storage server in response to at least one status verification request, the secondary storage server is confirmed to be available again.

[0068] In summary, by responding to the file upload request, at least one status verification request is sent to both the primary and secondary storage servers; upon receiving a status verification response from the primary storage server in response to at least one status verification request, it is determined that the primary storage server is in an available state; and upon receiving a status verification response from the secondary storage server in response to at least one status verification request, it is determined that the secondary storage server is in an available state. Thus, sending at least one status verification request to both the primary and secondary storage servers improves the accuracy of determining whether the primary and secondary storage servers are in an available state.

[0069] To enable file download functionality, in this embodiment of the disclosure, the application server can also obtain the file to be downloaded from at least one server, provided that at least one of the primary storage server and secondary storage servers is available. The following describes the process in conjunction with... Figure 3 Please provide a detailed explanation.

[0070] Figure 3 This is a schematic flowchart of the file storage method shown in the third embodiment of this disclosure.

[0071] like Figure 3 As shown, the method for storing this file may include the following steps:

[0072] Step 301: Receive the first file download request sent by the application client.

[0073] The first file download request includes the target file identifier of the file to be downloaded.

[0074] Step 302: In response to the first file download request, determine the second file type to which the file to be downloaded belongs based on the target file identifier, and determine the query directory to which the file to be downloaded belongs based on the second file type.

[0075] Step 303: Determine whether the primary storage server and / or secondary storage server are in an available state.

[0076] Step 304: If at least one of the primary storage server and the secondary storage server is available, send a second file download request to at least one server.

[0077] The second file download request includes a directory to be queried and a target file identifier. The second file download request is used to obtain a first target file that matches the target file identifier in the second storage directory and send the first target file to the application server. The second storage directory is a disk directory that the directory to be queried is allowed to link to.

[0078] In this embodiment of the disclosure, when at least one of the primary storage server and the secondary storage server is available, a second file download request is sent to at least one server to obtain the file to be downloaded from the at least one server.

[0079] As an example, when the primary storage server is available, a second file download request is sent to the primary storage server, wherein the second file download request is used to obtain a first target file that matches the target file identifier in the second storage directory of the primary storage server; when the primary storage server is unavailable, a second file download request is sent to the secondary storage server, wherein the second file download request is used to obtain a first target file that matches the target file identifier in the second target directory of the secondary storage server.

[0080] In other words, when the primary storage server is available, a second file download request is sent to the primary storage server to search for a first target file that matches the target file identifier in the secondary storage directory of the primary storage server. If a first target file that matches the target file identifier exists in the secondary storage directory of the primary storage server, the first target file is sent to the application server, and the application server sends the first target file as a download file to the application client. When the primary storage server is unavailable, a second file download request is sent to the secondary storage server to search for a first target file that matches the target file identifier in the secondary storage server's secondary storage directory. If a first target file that matches the target file identifier exists in the secondary storage server's secondary storage directory, the first target file is sent to the application server, and the application server sends the first target file as a download file to the application client.

[0081] As another example, if at least one of the primary storage server and secondary storage servers is not available, the system queries the directory to be queried to see if a second target file matching the target file identifier exists. If a second target file matching the target file identifier exists in the directory to be queried, the second target file is sent to the application client as a file to be downloaded. If no second target file matching the target file identifier exists in the directory to be queried, target information is sent to the application client, wherein the target information is used to indicate that the download of the file to be downloaded has failed.

[0082] In other words, when both the primary storage server and the secondary storage server are unavailable, the system checks whether a second target file matching the target file identifier exists in the query directory on the application server. If a second target file matching the target file identifier exists in the query directory, the second target file is sent to the application client as a file to be downloaded. If no second target file matching the target file identifier exists in the query directory, target information is sent to the application client, whereby the target information indicates that the download of the file to be downloaded has failed.

[0083] Step 305: Receive a first target file sent by at least one server, and send the first target file as a file to be downloaded to the application client.

[0084] In this embodiment of the disclosure, when a first target file matching the target file identifier exists in the second storage directory of at least one server, at least one server may send the first target file to the application server, and the application server may send the first target file as a file to be downloaded to the application client.

[0085] In summary, the process involves receiving a first file download request from an application client, wherein the first file download request includes a target file identifier for the file to be downloaded; responding to the first file download request, determining the second file type to which the file to be downloaded belongs based on the target file identifier, and determining the query directory to which the file to be downloaded belongs based on the second file type; determining whether the primary storage server and / or the secondary storage server are available; and if at least one of the primary and secondary storage servers is available, sending a second file download request to at least one server, wherein the second file download request includes the query directory and the target file identifier, and the second file download request is used to... The first target file matching the target file identifier is retrieved from the second storage directory and sent to the application server. The second storage directory is a disk directory that the query directory allows links to. The application server receives the first target file sent by at least one server and sends it as a file to be downloaded to the application client. Thus, when at least one of the primary and secondary storage servers is available, the application server queries the disk directories that the query directory allows links to from at least one server to see if the first target file matching the target file identifier is stored, improving file query efficiency. This improves download speed when the first target file exists on at least one server.

[0086] To implement the above embodiments, this disclosure proposes another file storage method.

[0087] Figure 4 This is a schematic flowchart illustrating the file storage method according to the fourth embodiment of this disclosure. It should be noted that the file storage method of this embodiment can be applied to a main storage server.

[0088] like Figure 4 As shown, the method for storing this file may include the following steps:

[0089] Step 401: Receive a file storage request sent by the application server.

[0090] The file storage request includes the file to be stored and the directory on the application server where the file to be stored is located. The directory is determined by the application server upon receiving the file upload request from the application client, based on the first file type of the file to be stored in the file upload request. The file storage request is sent by the application server in response to the file upload request, after determining that the main storage server is in an available state.

[0091] In this embodiment of the disclosure, in response to a user upload operation, the application client sends a file upload request to the application server. When the application server receives the file upload request from the application client, it can determine the storage directory of the file to be stored on the application server based on the first file type to which the file to be stored belongs in the file upload request. In response to the file upload request, the application server can determine whether the primary storage server and / or secondary storage server are in an available state, and if the primary storage server is in an available state, it sends a file storage request to the primary storage server. The file storage request may include the file to be stored and the storage directory of the file to be stored on the application server.

[0092] Step 402: Determine the first storage directory based on the directory to be stored.

[0093] The first storage directory is the disk directory that the directory to be stored is allowed to link to.

[0094] Because the storage directories in the application server are mapped to the directories in the primary and secondary storage servers, the primary storage server can determine the first storage directory for storing the files to be stored based on the directory to be stored. The first storage directory is the disk directory to which the directory to be stored is allowed to link; that is, the files to be stored are stored on the disk of the primary storage server.

[0095] Step 403: Store the file to be stored in the first storage directory.

[0096] Then, the file to be stored is stored in the first storage directory.

[0097] In this embodiment of the disclosure, after storing the file to be stored in the first storage directory, as an example, it can also be determined whether the slave storage server is in an available state. If the slave storage server is in an available state, a file synchronization request can be sent to the slave storage server. The file synchronization request may include the file to be stored and the first storage directory. The slave storage server can respond to the file synchronization request and synchronize the file to be stored to its own first storage directory.

[0098] As another example, whenever a set period is reached, the primary storage server can determine whether the secondary storage server is available. If the secondary storage server is available, the latest files stored on the primary storage server during that period will be synchronized and updated to the secondary storage server.

[0099] In summary, by receiving a file storage request from the application server, where the request includes the file to be stored and the storage directory on the application server, and the storage directory is determined by the application server upon receiving a file upload request from the application client, identifying the first file type of the file to be stored, and determining that the main storage server is available based on the first file type, the file storage request is sent by the application server in response to the file upload request. Based on the storage directory, a first storage directory is determined, which is a disk directory that the storage directory is allowed to link to. The file to be stored is then stored in the first storage directory. This allows the file to be stored on the disk directory of the main storage server, reducing the storage pressure on the application server, improving its operating speed, and thus increasing the efficiency of related business processing.

[0100] In this embodiment of the disclosure, when the client responds to a download operation, it can send a first file download request to the application server. When the application server determines that the main storage server is available, it can send a second file download request to the main storage server to download the first target file that matches the target file identifier. The following describes the process in conjunction with... Figure 5 Please provide a detailed explanation.

[0101] Figure 5 This is a schematic flowchart illustrating the file storage method according to the fifth embodiment of this disclosure. It should be noted that the file storage method of this embodiment can be applied to a main storage server.

[0102] like Figure 5 As shown, the method for storing this file may include the following steps:

[0103] Step 501: Receive the second file download request sent by the application server.

[0104] The second file download request is sent by the application server after determining that the main storage server is in an available state. The second file download request includes the directory to be queried and the target file identifier. The directory to be queried is determined by the main storage server upon receiving the first file download request sent by the application client and responding to the first file download request. Based on the target file identifier in the first file download request, the main storage server determines the second file type to which the file to be downloaded in the first file download request belongs, and determines it based on the second file type.

[0105] In this embodiment of the disclosure, the application server can receive a first file download request sent by the application client. The first file download request includes a target file identifier for the file to be downloaded. In response to the first file download request, the application server determines a second file type for the file to be downloaded based on the target file identifier, determines the directory to be queried based on the second file type, and checks whether the main storage server is available. If the main storage server is available, the application server sends a second file download request to the main storage server. The second file download request includes the directory to be queried and the target file identifier.

[0106] Step 502: In response to the second file download request, retrieve the first target file that matches the target file identifier from the second storage directory.

[0107] The second storage directory is the disk directory that the query directory is allowed to link to.

[0108] Furthermore, in response to the second file download request, it is determined whether a first target file matching the target file identifier exists in the second storage directory. If a first target file matching the target file identifier exists in the second storage directory, the first target file matching the target file identifier is retrieved from the second storage directory.

[0109] Step 503: Send the first target file to the application server.

[0110] The first target file is used as the file to be downloaded and sent to the application client.

[0111] Then, the first target file is sent to the application server, which can then send the first target file to the application client as a file to be downloaded.

[0112] In summary, by receiving a second file download request from the application server; responding to the second file download request, retrieving a first target file matching the target file identifier from the second storage directory; and sending the first target file to the application server, whereby the first target file is used as the file to be downloaded to the application client, the file to be downloaded can be quickly located from the main storage during file download, improving download speed and thus enhancing user experience.

[0113] Based on any embodiment of this disclosure, such as Figure 6 As shown, the file storage method of this disclosure embodiment can also be implemented based on the following steps:

[0114] 1. When uploading image files, in order to improve the transmission speed and file transmission security, the image file to be uploaded can be converted into a data stream, and the data stream can be encapsulated to obtain an encapsulated message;

[0115] It should be noted that, since the original storage solution only stored txt files using FTP (File Transfer Protocol), the addition of image and video file storage functions made development more complicated. At the same time, the frequent patching of FTP vulnerabilities increased maintenance costs. Therefore, in this embodiment, NFS (Network File System) network disk can be used to store image files and other files, which is convenient for development and integration, and reduces the workload of maintenance.

[0116] 2. The local server (application server) receives the encapsulated message sent by the client (application client), decapsulates the encapsulated message to obtain the file to be uploaded, determines the file type of the file to be uploaded, and determines the storage directory based on the file type of the file to be uploaded.

[0117] 3. Perform mount service verification on the primary and secondary storage servers, i.e., determine whether the primary and secondary storage servers are in an available state. If at least one of the primary and secondary storage servers is available, a file storage request can be sent to at least one server to store the file to be stored in the first storage directory, which is a disk directory that the storage directory is allowed to link to. If neither the primary nor secondary storage server is available, the application server can store the file to be stored in the storage directory.

[0118] It should be noted that, due to the small initial workload, a single-machine mode can be used. As the workload increases, the availability, data security, and completeness of the storage service become priorities. Subsequently, the storage architecture was upgraded to a master-slave dual-machine mode, which can realize hourly scheduled data synchronization. In addition, it should be noted that relevant departments discovered a security risk that any host could view and access the service. This issue can be addressed by adding the function of only allowing service discovery and only allowing service access to specified IP hosts to the master and slave storage servers.
