While online file transfer provides convenience, it also brings corresponding security risks. Therefore, it is necessary to establish a secure, accurate, and efficient file transfer system.

[0003] The existing file transfer method uses the OSS file storage system. The file provider pulls the specified data content based on the specified file format to generate a file, uploads it to the path specified by the OSS file storage system, and informs the file recipient of the storage path. The file recipient then downloads the specified file from the OSS file storage system according to the storage path.

[0004] Because the OSS file storage system is not fully automated, it consumes a lot of manpower and time during file transfer, and there is a possibility of human error and missing files, resulting in a high error rate in file transfer and thus affecting the efficiency of file transfer. Furthermore, downloading files from the OSS file storage system cannot guarantee that all files will be downloaded at once, and unclear download permissions can easily lead to unauthorized access, failing to meet security requirements. Therefore, existing technologies suffer from low file transfer efficiency and poor security. Summary of the Invention

[0070] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0071] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims.

[0072] In existing technologies, file transfer is performed using the OSS file storage system. The file provider pulls specified data content based on a specified file format to generate a file, which is then uploaded to a specified path in the OSS file storage system. However, human error and file omissions may occur during the upload process, affecting the efficiency of file transfer. After the file is uploaded, the storage path is informed to the file recipient, who then downloads the specified files from the OSS file storage system according to the storage path. However, it is not guaranteed that all files will be downloaded at once, and download permissions are unclear, making unauthorized access easy to occur. The entire file transfer process also consumes a lot of manpower and time. Therefore, existing technologies suffer from low file transfer efficiency and poor security.

[0073] The file transfer method, device, and storage medium provided in this application respond to file transfer business requests based on a distributed file system. They determine at least one file provider user corresponding to the file transfer, and uniformly store the target file transfer file through the distributed file system to ensure its integrity and high availability. They configure corresponding file interfaces for the target file transfer, set transfer rules based on these interfaces, and determine at least one file receiver user based on these rules. They manage both the file provider and receiver users uniformly and isolate permissions between different users to ensure the security of the target file transfer. They authenticate both the file provider and receiver users; if authentication is successful, file transfer is established between them using a preset method. This prevents attacks on the file transfer process when user account information is leaked. Furthermore, the transfer process of the target file transfer within the distributed file system requires no manual intervention, and the file provider and receiver users do not need to interact with the distributed file system multiple times, reducing the risk of interface conflicts and achieving the technical effects of improving file transfer efficiency and security.

[0074] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0075] Figure 1 The file transfer method flow provided in the embodiments of this application Figure 1 .like Figure 1 As shown, this embodiment provides a file transfer method, including:

[0076] S101. In response to the business request for file transfer, determine at least one file providing user corresponding to the file transfer;

[0077] In this embodiment, the entire file transfer process relies on the GlusterFS distributed file system and follows the secure file transfer protocol SFTP. The GlusterFS distributed file system is a scalable network file system. Compared with other distributed file systems, the GlusterFS distributed file system has the characteristics of high scalability, high availability, and high performance. Figure 2 Scenario for the file transfer method provided in the embodiments of this application Figure 1 ,like Figure 2As shown, the GlusterFS distributed file system adopts an architecture consisting of a management layer, a Master central control layer, and a Worker workflow processing layer. The management layer is operated by system personnel using corresponding programs, including maintaining and managing the GlusterFS distributed file system. The Master central control layer serves as the central system for communication control between the management layer and the Worker workflow processing layer, primarily managing the various clusters within the Worker workflow processing layer and the allocation of workflow rules. The Worker workflow processing layer is mainly responsible for processing the file workflow and is the core business layer of the GlusterFS distributed file system. System operators receive file workflow requests at the management layer and determine at least one file corresponding to the workflow to provide to the user. For example, this can be achieved through a Celery distributed task queue, using multiple threads to process file workflow requests.

[0078] S102. Configure the corresponding file interface for the target file to be transferred, and set the transfer rules based on the file interface, and determine at least one file receiving user based on the transfer rules;

[0079] In this embodiment, as Figure 3 Scenario for the file transfer method provided in the embodiments of this application Figure 2 ,like Figure 3As shown, the GlusterFS distributed file system can be divided into a system configuration module, a user management module, a workflow management module, a file exchange management module, a workflow log management module, and a whitelist management module according to its functional architecture. The system configuration module includes cluster management, application management, system monitoring, and system configuration. Cluster management manages the entire GlusterFS distributed file system cluster and maintains cluster information, such as adding, deleting, and modifying data. Application management synchronizes application information from the file management platform for easier maintenance. The user management module includes local users, remote users, user groups, and user export. Local and remote users manage the local and remote user information for each cluster. Local user information includes basic information such as username and password, as well as space limits. Remote user information includes basic information such as username and password. User groups are used to divide users into groups for easier user management and workflow rule maintenance. The export module is used to export user information for auditing and maintenance. The file transfer management module is used to transfer files, including local transfer, remote transfer, upload transfer, download transfer, one-to-one transfer, one-to-many transfer, many-to-one transfer, and many-to-many transfer. The file exchange management module includes file interface management, upload and download management, scheduled file cleanup, and file editing. File interface management is used to maintain and modify file interfaces for reuse and integration with other systems. Scheduled file cleanup is used to prevent excessive files from affecting the overall performance and stability of the GlusterFS distributed file system. The file transfer log management module includes file transfer chains and log queries. The file transfer chain records a series of process logs from the start to the end of the file transfer, including log information for file comparison, backup, transfer, and deletion. The whitelist management module includes adding / editing whitelists. The whitelist management module is used to authenticate users and prevent attackers from launching login attacks if user account passwords are leaked.

[0080] In this embodiment, the target file for file transfer is determined based on the received file transfer business request, and a corresponding file interface is configured for the target file according to the business request, including the Chinese name of the configuration file interface, the English name of the file interface, the application, the file server cluster, the file interface path, and related remarks. At least one file is assigned to a corresponding user group based on a preset category, such as grouping by province, and transfer rules are set for each user group based on the corresponding active servers; wherein, the transfer rules include one-to-one transfer, one-to-many transfer, many-to-one transfer, and many-to-many transfer.

[0081] In the first example, Figure 4 Scenario for the file transfer method provided in the embodiments of this application Figure 3 ,like Figure 4As shown, based on VIP and Keepalived technologies, it is determined whether the corresponding server is in normal working condition. If not, the flow rules are set for other servers in normal working condition through VRRP protocol or custom script.

[0082] In this embodiment, based on the principle of load balancing, the flow rules are distributed to the corresponding Worker flow processing layer clusters, and at least one file receiving user is determined by the cluster where the flow rules are located. When there are many flow rules and the pressure on the Worker flow processing layer is high, the Worker flow processing layer can be dynamically expanded horizontally to ensure the timeliness and reliability of the flow rules. The flow rules are stored in the database.

[0083] In the second example, Figure 5 Scenario for the file transfer method provided in the embodiments of this application Figure 4 ,like Figure 5 As shown, based on the consistent hashing algorithm, the hash value of the transfer rule is calculated and the hash value of the Worker transfer processing layer cluster is compared. The two hash values ​​are then compared to determine the cluster where the transfer rule is located, and thus determine at least one corresponding file receiving user. If a cluster goes down, the hash value of the transfer rule and the hash value of the Worker transfer processing layer cluster are recalculated, and the transfer rule is allocated to ensure the high availability of the transfer rule.

[0084] S103. Verify the identity of the file provider and the file receiver. If the verification is successful, establish a file transfer between the file provider and the file receiver based on a preset method.

[0085] In this embodiment, the user providing the file and the user receiving the file are authenticated. If the authentication is successful, the user providing the file and the user receiving the file are added to the whitelist.

[0086] In the third example, Figure 6 Scenario for the file transfer method provided in the embodiments of this application Figure 5 ,like Figure 6 As shown, FULLNAT and TOA technologies are used to locate the IP addresses of file providers and file receivers, ensuring the traceability of file providers and file receivers, thereby identifying users with login permissions. Based on the Layer 4 load balancing protocol of SLB, a security whitelist is configured for file providers and file receivers.

[0087] In this embodiment, it is determined whether the transfer rule conforms to a preset mode. If so, an instruction to upload the target transfer file is sent to the file providing user, and the corresponding transfer method is determined based on the transfer rule. The storage directory of the target transfer file is determined based on the transfer method. An instruction to download the target transfer file is sent to the file receiving user, and the target transfer file is downloaded based on the storage directory. The transfer method includes local transfer and remote transfer. Remote transfer includes SFTP upload and SFTP download. Local transfer refers to file transfer that occurs on the local cluster. After the local file providing user uploads the target transfer file, the target transfer file will be transferred to the directory of the local file receiving user. SFTP upload is the transfer of the target transfer file uploaded by the local file providing user to the directory of the remote file receiving user via the SFTP protocol. SFTP download is the download of the target transfer file from the remote file providing user to the directory of the local file receiving user via the SFTP protocol.

[0088] In the fourth example, the flow rules are obtained by scanning the SQLite3 database. Based on the custom pattern template - Shell-pattern expression, it is determined whether the flow rules match the Shell-pattern expression. If they match, file flow is allowed. If they do not match, the mismatched flow rules are filtered out and file flow is not allowed.

[0089] In the fifth example, Figure 7 Scenario for the file transfer method provided in the embodiments of this application Figure 6 ,like Figure 7 As shown, based on the file provider user, it is determined whether the file recipient user is a local user or a remote user. If it is a local user, the file provider user logs into the GlusterFS distributed file system via the SFTP security protocol, uploads the target transfer file to the specified storage directory on the local server, and the file recipient user retrieves the target transfer file from the specified storage directory via the SFTP security protocol. If it is a remote user, the file provider user logs into the GlusterFS distributed file system via the SFTP security protocol, uploads the target transfer file to the local server, and then sends the target transfer file to the specified storage directory on the remote server via the local server. The file recipient user retrieves the target transfer file from the specified storage directory via the SFTP security protocol.

[0090] In this embodiment, it is determined whether the file management platform associated with the target circulating file has modification permissions. If so, the target circulating file in the storage directory is edited based on the file management platform; the storage directory is updated based on the edited target circulating file.

[0091] In this embodiment, after the file transfer is completed, the file transfer log is obtained based on the file transfer chain. The target transfer file, process files generated during editing, and the edited target transfer file are located based on the file transfer log and backed up, such as using RAID technology, GlusterFS replicated volumes, or distributed replicated volumes for file storage. The file transfer log can also be used to check for problems during the file transfer process, ensuring timely troubleshooting. Furthermore, all files in the storage directory are retrieved and cleaned up according to certain rules to prevent excessive files from affecting system stability.

[0092] The file transfer method provided in this application responds to file transfer business requests based on a distributed file system. It identifies at least one file provider corresponding to the file transfer, and uses the distributed file system to uniformly store the target file, ensuring its integrity and high availability. It configures corresponding file interfaces for the target file and assigns at least one file provider to a corresponding user group based on preset categories. Transfer rules are set for each user group and distributed to the corresponding transfer processing layer cluster. At least one file receiver is identified through the cluster containing the transfer rules. File providers and receivers are managed uniformly, and access is isolated between different users to ensure the security of the target file. The method authenticates both the file provider and receiver. If authentication is successful, file transfer is established between them based on transfer rules conforming to a preset pattern. This prevents attacks on the file transfer process when user account information is leaked. Furthermore, the transfer process of the target file within the distributed file system requires no manual intervention, and file providers and receivers do not need to interact with the distributed file system multiple times, reducing the risk of interface conflicts and achieving the technical effects of improving file transfer efficiency and security.

[0093] Figure 8 The file transfer method flow provided in the embodiments of this application Figure 2 .like Figure 8 As shown in the embodiment of this application, a file transfer method includes:

[0094] S801. In response to a business request for file transfer, determine at least one file-providing user corresponding to the file transfer;

[0095] S802. Configure the corresponding file interface for the target file to be transferred, and assign at least one file to the corresponding user group based on the preset category; set the corresponding transfer rules for each user group based on the file interface; determine at least one file receiving user based on the transfer rules;

[0096] S803. Verify the identity of the file provider and the file receiver. If the verification is successful, determine whether the transfer rules conform to the preset mode. If so, send the first instruction information to the file provider. The first instruction information is used to instruct the file provider to upload the target transfer file.

[0097] S804. Determine the corresponding transfer method based on the transfer rules, determine the storage directory of the target transfer file based on the transfer method, and upload the target transfer file to the storage directory; wherein, the transfer method includes local transfer and / or remote transfer;

[0098] S805. Determine whether the file management platform associated with the target streaming file has modification permissions. If so, edit the target streaming file in the storage directory based on the file management platform; update the storage directory based on the edited target streaming file.

[0099] S806. Send a second instruction message to the file receiving user; wherein the second instruction message is used to instruct the file receiving user to download the target streaming file; download the target streaming file based on the storage directory;

[0100] S807. Obtain the file flow log, and based on the file flow log, find the target flow file, the process file generated during the editing process, and the edited target flow file; save the target flow file, the process file, and the edited target flow file based on a preset path;

[0101] S808: Obtain all files stored in the storage directory; clean up the files based on preset requirements.

[0102] By executing steps S801 to S808, in response to business requests for file transfer based on a distributed file system, at least one file-providing user corresponding to the file transfer is identified. The target transfer file is stored uniformly through the distributed file system, ensuring its integrity and high availability. A corresponding file interface is configured for the target transfer file, and at least one file-providing user is assigned to a corresponding user group based on a preset category. Transfer rules are set for each user group, and these rules are distributed to the corresponding transfer processing layer cluster. At least one file-receiving user is determined based on the cluster containing the transfer rules. File-providing and file-receiving users are managed uniformly, and information is shared across different user groups. Access control is implemented between different systems to ensure the security of the target file. The system authenticates both the file provider and the file receiver. If authentication is successful, it checks if the file transfer rules conform to a preset pattern. If so, it instructs the file provider to upload the target file, determines the appropriate transfer method based on the rules, identifies the storage directory for the target file based on the transfer method, and instructs the target receiver to download the file. The file transfer process within the distributed file system requires no manual intervention. The file provider and receiver do not need to interact with the distributed file system multiple times, reducing the risk of interface conflicts and achieving the technical effects of improving file transfer efficiency and security.

[0103] In the sixth example, Figure 9 Scenario for the file transfer method provided in the embodiments of this application Figure 7 ,like Figure 9 As shown, firstly, the system operator determines at least one file provider user corresponding to the file transfer based on the received file transfer business request, and configures the corresponding file interface for the target file to be transferred. Secondly, based on preset categories, at least one file provider user is assigned to a corresponding user group, and transfer rules are set for each user group. Based on the load balancing principle, the transfer rules are distributed to the corresponding Worker transfer processing layer clusters, and at least one file receiving user is determined through the cluster where the transfer rules are located. Finally, the file provider user and the file receiving user are notified to upload and download the file, thus realizing the file transfer between the file provider user and the file receiving user.

[0104] The file transfer method provided in this application responds to business requests for file transfer based on a distributed file system. It identifies at least one file provider corresponding to the file transfer, stores the target file in a unified manner through the distributed file system, ensuring the integrity and high availability of the target file. It configures corresponding file interfaces for the target file and assigns at least one file provider to a corresponding user group based on preset categories. Transfer rules are set for each user group, and at least one file receiver is identified based on these rules. The file provider and receiver are managed uniformly, and access is isolated between different users to ensure the security of the target file. The method authenticates both the file provider and receiver. If authentication is successful, file transfer is established between them using a preset method, preventing attacks on the file transfer process when user account information is leaked. Furthermore, the transfer process of the target file within the distributed file system requires no manual intervention, and the file provider and receiver do not need to interface with the distributed file system multiple times, reducing the risk of interface failures and achieving the technical effects of improving file transfer efficiency and security.

The distributed file system uniformly stores the target transfer file, ensuring its integrity and high availability. The first processing module configures corresponding file interfaces for the target transfer file and assigns at least one file-providing user to a corresponding user group based on preset categories. Transfer rules are set for each user group, and these rules are distributed to the corresponding transfer processing layer cluster. The cluster containing the transfer rules determines at least one corresponding file-receiving user. The device then processes the file-providing and file-receiving users. Unified management and permission isolation between different users ensure the security of the target circulating files. The second processing module authenticates the file provider and file receiver. If the authentication is successful, it determines whether the circulation rules conform to the preset pattern. If so, it instructs the file provider to upload the target circulating file, determines the corresponding circulation method based on the circulation rules, determines the storage directory of the target circulating file based on the circulation method, and instructs the target receiver to download the target circulating file. The circulation process of the target circulating file within the distributed file system does not require manual intervention. The file provider and file receiver do not need to interact with the distributed file system multiple times, reducing the risk of interaction and achieving the technical effect of improving file circulation efficiency and security.
