Technical Field
[0001] This application relates to the technical field of file transfer, and particularly to a file transfer verification method, apparatus, device, and computer program product. Background Art

[0047] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.
[0048] The following will, with reference to the drawings, elaborate on the technical solutions provided by each embodiment of the present application.
[0049] The verification solution for the number of files sent and received based on the acknowledgment mechanism mainly includes the following steps:
[0050] 1) The file sender divides the batch of files to be transmitted into multiple data packets and generates a unique sequence number for each data packet;
[0051] 2) The file sender sends each data packet to the file receiver and waits for the acknowledgment from the receiver;
[0052] 3) After receiving the data packet, the file receiver checks it. If the check passes, it sends an acknowledgment to the file sender;
[0053] 4) After receiving the acknowledgment, the file sender continues to send the next data packet;
[0054] 5) If the file sender does not receive the acknowledgment within the set time, it will retransmit the data packet.
[0055] Although the above acknowledgment mechanism can ensure the data integrity of file transmission, it also has the following disadvantages:
[0056] 1) In the scenario of batch file transmission, the acknowledgment mechanism will increase the overhead of network bandwidth and processing time;
[0057] 2) In scenarios with high real-time requirements, the file sender needs to wait for the acknowledgment from the receiver to continue sending the next segment of data. In the scenario of file transmission failure, the failed file needs to be retransmitted, which will increase the overall transmission time and reduce the file processing speed, and cannot meet the requirements of high real-time.
[0058] Based on this, the embodiments of the present application provide a file transmission verification method. As Figure 1 shown, a flowchart of a file transmission verification method in the embodiments of the present application is provided. The file transmission verification method is executed by the file verifier, and the file transmission verification method at least includes the following steps S110 to step S140:
[0059] Step S110: Receive the file sending information sent by the file sender.
[0060] Combined Figure 2 , a schematic diagram of a file transfer verification process in an embodiment of the present application is provided. The file transfer verification method in the embodiment of the present application is executed by the file verifier. A communication connection is established between the file verifier and the file sender, and this connection can be implemented based on a specific network protocol (such as the Http protocol, etc.). During the process of sending a file, the file sender can package the file sending information according to a predetermined format and specification and send it to the file verifier through this communication connection. The file verifier listens to the corresponding port or channel, receives the data packet from the file sender in real time, and extracts the file sending information from the data packet according to the predetermined protocol parsing rules.
[0061] The file sending information can, for example, include the identification information of the file (such as the file name, file number, etc.) and the number of files sent, and can also include the information of the recipient who receives the file, etc., as one of the bases for subsequent file verification to ensure that the file verifier can accurately identify and verify the file.
[0062] Step S120: Receive the file receiving information sent by the file recipient.
[0063] Similarly, a communication connection is also established between the file verifier and the file recipient. After successfully receiving the file, the file recipient will generate file receiving information and send the file receiving information to the file verifier in a communication manner similar to that of the file sender. The file verifier listens to the corresponding port or channel, receives the data packet from the file recipient, and parses out the file receiving information.
[0064] The file receiving information can, for example, include the identification information of the file (such as the file name, file number, etc.), the number of files received, and the information of the file recipient, etc. These information are used to compare with the file sending information to determine whether the file has been successfully transferred.
[0065] Step S130: Perform file verification based on the file sending information and the file receiving information to obtain a file verification result, where the file verification result includes consistent verification and inconsistent verification.
[0066] After receiving the file sending information and the file receiving information, the file verifier can perform file verification based on the file sending information and the file receiving information. The purpose of the verification is to ensure that all the files sent by the file sender are successfully received by the recipient. According to the verification result of the file sending and receiving information, the file verifier will obtain a result of consistent verification or inconsistent verification. Consistent verification means that all the files sent by the file sender are successfully received by the recipient, while inconsistent verification means that the files sent by the file sender are not completely received by the recipient.
[0067] Step S140, in the case where the file verification result is inconsistent, determine file transfer difference information according to the file sending information and the file receiving information, and send the file transfer difference information to the file sender, so that the file sender can re-send the file according to the file transfer difference information.
[0068] If the file verification result is inconsistent, it is necessary to further determine the file transfer difference information by combining the file sending information and the file receiving information. The file transfer difference information refers to the file information that has been sent by the file sender but not successfully received by the receiving party, and these files need to be re-sent.
[0069] After determining the file transfer difference information, the file verifier needs to feedback the file transfer difference information to the file sender, so as to facilitate the file sender to directly reissue the file according to the file transfer difference information, and then ensure the integrity of the file received by the file receiving party.
[0070] The file transfer verification method of the embodiments of the present application realizes the data integrity of file transfer and the efficient transfer of file data in the scenario of batch file transfer. On the one hand, by decoupling the file verification process from the file transfer process, the number of file confirmation responses between the file sender and the receiver during file transfer is reduced, thereby reducing the operations between the two parties of file transfer and improving the transfer efficiency of file data; on the other hand, the file verifier can screen out the files that have not been successfully received according to the file information sent by the file sender and the receiver, which is convenient for the file sender to reissue the missing files and ensures the integrity of the transferred file data.
[0071] In some embodiments of the present application, after receiving the file sending information sent by the file sender, the file transfer verification method further includes: storing the file sending information in a file sending information table; after receiving the file receiving information sent by the file receiver, the file transfer verification method further includes: storing the file receiving information in a file receiving information table.
[0072] Continue to refer to Figure 2 , after receiving the file sending information sent by the file sender, it is necessary to register the file sending information, that is, store the file sending information in a specially designed file sending information table. This file sending information table can be a database table with a specific field structure to store file sending information, such as file name, file size, sending time, sender identifier, receiver identifier, sending status, etc. Specifically, which field information is included can be flexibly set by those skilled in the art according to actual needs and will not be specifically limited here.
[0073] Similarly, after receiving the file receiving information sent by the file recipient, it is necessary to register the file receiving information, that is, store the file receiving information in a specially designed file receiving information table. The file receiving information table can also be a database table with specific fields to store relevant information about file reception, such as file name, reception time, recipient identifier, sender identifier, etc. Specifically, which field information is included can be flexibly set by those skilled in the art according to actual needs and will not be specifically limited here.
[0074] By storing the file sending information and the file receiving information into the file sending information table and the file receiving information table respectively in the embodiments of the present application, the transmission process of each file can be detailedly recorded, providing a strong data basis for subsequent file verification.
[0075] In some embodiments of the present application, the file verification based on the file sending information and the file receiving information to obtain a file verification result includes: obtaining the file sending information from the file sending information table, where the file sending information includes the sending file name and the file recipient information; obtaining the file receiving information from the file receiving information table, where the file receiving information includes the received file name and the file recipient information; and performing file verification based on the file sending information and the file receiving information to obtain the file verification result.
[0076] Continue to refer to Figure 2 , when performing file verification, the file verifier respectively obtains the file sending information from the file sending information table and the file receiving information from the file receiving information table, and then verifies information such as the number of files and the file name based on the obtained file sending information and file receiving information.
[0077] Considering the actual application scenario, the file sender may send files to multiple file recipients. When obtaining the above file information from the database table, the file sending information of the file sender can be first obtained from the file sending information table. Since the file sending information includes the sending file name and the file recipient information, the corresponding file receiving information of the file recipient can be further obtained from the file receiving information table according to the file recipient information therein for verification. Of course, in the actual application scenario, there may also be a situation where a file recipient receives files sent by multiple file senders. Therefore, the files received by the same file recipient from different file senders can also be further distinguished and verified separately. For example, they can be distinguished according to the sender identifier in the file receiving information.
[0078] By obtaining detailed file sending information and file receiving information from the file sending information table and the file receiving information table respectively, key information in the file verification process can be obtained quickly and accurately, which avoids verification deviations caused by incomplete or incorrect information and improves the accuracy and efficiency of file verification.
[0079] In some embodiments of the present application, the file sending information further includes the number of sent files, and the file receiving information further includes the number of received files. The file verification based on the file sending information and the file receiving information to obtain a file verification result includes: comparing the number of sent files of the file sender with the number of received files of the file receiver; if the numbers are the same, determining that the file verification result is consistent; otherwise, determining that the file verification result is inconsistent.
[0080] As mentioned above, after the file sender completes file sending, it will send the sent file name, the number of sent files, and the file receiver information, etc. to the file verifier. After the file receiver completes file receiving, it will send the received file name, the number of received files, and the file receiver information, etc. to the file verifier. Therefore, when performing file sending and receiving verification, the number of files already sent by the file sender can be compared with the number of files actually received by the file receiver first. If the number of files is the same, the file verification result can be directly determined to be consistent. If the number of files is different, the file verification result can be determined to be inconsistent.
[0081] For example, if file sender A sends 10 files to file receiver B, and file receiver B also receives 10 files and these 10 files are from file sender A, then file receiver B has received complete file data. If the number of files received by file receiver B from file sender A is less than 10, it means that the file data received by file receiver B is incomplete.
[0082] Embodiments of the present application can timely detect problems such as file transmission failure or loss during the file transmission process through the verification of the file sending quantity and the received quantity, and thus can ensure the integrity of the file data received by the file receiver.
[0083] In some embodiments of the present application, the file sending information table further stores file status information. When the file verification result is inconsistent, determining the file transfer difference information according to the file sending information and the file receiving information includes: when the file verification result is inconsistent, obtaining the file name with the file status information of the unchecked state from the file sending information table; according to the file name in the unchecked state and the file receiving party information, obtaining the corresponding file receiving information from the file receiving information table; determining the file transfer difference information according to the obtaining result of the corresponding file receiving information.
[0084] In addition to storing basic file sending-related information, the file sending information table in the embodiments of the present application also stores file status information additionally. The file status information is used to identify different stages of the file in the transfer verification process, such as "unchecked", "verified", etc. This provides a key basis for status judgment in the subsequent verification process.
[0085] Continue to refer to Figure 2 , when the file verification result is inconsistent, a specific processing logic will be triggered. First, obtain all the file names with the file status information of "unchecked state" from the file sending information table. Since the foregoing embodiments are only based on the verification of the file quantity, in the case of inconsistent file quantities, it is necessary to further determine which files the file receiving party did not receive specifically. Therefore, at the initial stage of the execution of this processing logic, it can be considered that all the files sent by the file sending party this time are in the unchecked state, and then each unchecked file is verified and judged one by one.
[0086] For the currently traversed file name in the unchecked state and the corresponding file receiving party information (such as the receiving party number), the file receiving information corresponding to this file receiving party can be found from the file receiving information table, and then it can be determined whether the file corresponding to the currently traversed file name in the unchecked state has been successfully received by the file receiving party according to the search result. And so on, each unchecked file is verified one by one, so that the file information that has not been received by the file receiving party can be finally determined, that is, the above-mentioned file transfer difference information.
[0087] By introducing file status information, it is possible to clearly distinguish which files need to be verified, and only process the files in the unchecked state, avoiding the interference of verified files, thereby improving the accuracy of locating different files. At the same time, accurately searching for file receiving information according to the file name and file receiving party information further ensures the accuracy of file verification.
[0088] Only process the files in the unchecked state, reducing unnecessary calculation and query operations, and greatly improving the processing efficiency.
[0089] In some embodiments of the present application, determining the file transfer difference information according to the acquisition result of the corresponding file reception information includes: if the acquisition result is that the corresponding file reception information is acquired, updating the corresponding file status information to the verified status in the file sending information table; if the acquisition result is that the corresponding file reception information is not acquired, updating the corresponding file status information to the retransmission required status in the file sending information table.
[0090] Continue to refer to Figure 2 , if the file reception information corresponding to the file recipient can be acquired from the file reception information table, it indicates that the file corresponding to the file name in the unverified status currently traversed has been received by the file recipient. Therefore, the corresponding file status can be updated to verified. If the file reception information corresponding to the file recipient cannot be acquired from the file reception information table, it may indicate that the file is lost or the transmission fails during the transmission process. At this time, the corresponding file status needs to be updated to the retransmission required status so that the file sender can retransmit it later.
[0091] By updating the file status information to the "verified status" or "retransmission required status", the file status management in the file sending information table becomes clearer and more explicit, which helps the subsequent file sender to retransmit the files that need to be retransmitted, thereby ensuring the integrity of the file data received by the file recipient.
[0092] In some embodiments of the present application, determining the file transfer difference information according to the acquisition result of the corresponding file reception information includes: screening out the file information with the file status information of the retransmission required status from the file sending information table as the file transfer difference information.
[0093] Based on the foregoing embodiments, the statuses of all unverified files in the file sending information table are updated to the "verified status" or "retransmission required status". The "verified status" indicates the files successfully received by the file recipient, while the "retransmission required status" indicates the files not received by the file recipient. Therefore, all the file information with the "retransmission required status" can be screened out from the file sending information table. These files are the files that need to be retransmitted by the file sender, that is, used as the file transfer difference information.
[0094] By recording and maintaining the file sending status information through the file sending information table, the file information that needs to be retransmitted can be quickly and timely located, thereby improving the integrity of file reception and the file sending and receiving efficiency.
[0095] In summary, the key points of the file transfer verification method of the present application mainly lie in:
[0096] 1) Implement the verification of the number of files using the proxy method. The file sender and receiver of this application provide file information to the file verifier, and the file verifier verifies the file sending and receiving situation, reducing the coupling degree between the file transmission process and the verification process;
[0097] 2) Simplify the file transmission process and improve the transmission efficiency. During the file sending and receiving by the file sender and receiver of this application, only file sending and receiving operations are performed. After the file transmission is completed, the information is sent to the file verifier, reducing the confirmation and response operations between the file sender and receiver during file transmission;
[0098] 3) Ensure the integrity of the transmitted file quantity. This application verifies the number of files sent and received through the file verifier, checks the file sending and receiving results. If the sending and receiving quantities are inconsistent, the file verifier counts the information of the files not sent and notifies the file sender to re - send the files.
[0099] This application adopts the method of decoupling the file sending and receiving process from the verification process, reducing the impact of the sender's frequent confirmation of the file reception result on the overall file transmission efficiency, and improving the efficiency of batch file transmission. By uniformly comparing the file sending result and the receiving result through the file verifier, if there are files that have not been successfully received, the sender re - issues the files, ensuring the integrity of the file transmission.
[0100] The embodiment of this application also provides a file transmission verification device 300, as Figure 3 shown, providing a structural schematic diagram of a file transmission verification device in the embodiment of this application. The file transmission verification device 300 is applied to the file verifier. The file transmission verification device 300 at least includes: a first receiving module 310, a second receiving module 320, a file verification module 330, and a file verification result feedback module 340, where:
[0101] The first receiving module 310 is used to receive the file sending information sent by the file sender;
[0102] The second receiving module 320 is used to receive the file receiving information sent by the file receiver;

[0105] In some embodiments of the present application, the file transfer verification device 300 further includes: a file information registration module, configured to store the file sending information into a file sending information table after receiving the file sending information sent by a file sender; and further configured to store the file receiving information into a file receiving information table after receiving the file receiving information sent by a file receiver.

The file verification module 330 is specifically configured to: verify the number of sent files of the file sender and the number of received files of the file receiver; if the numbers are consistent, determine that the file verification result is consistent; otherwise, determine that the file verification result is inconsistent.
[0108] In some embodiments of the present application, the file status information is further stored in the file sending information table. The file verification result feedback module 340 is specifically configured to: in the case where the file verification result is inconsistent, obtain the file name with the file status information being the unverified status from the file sending information table; obtain the corresponding file receiving information from the file receiving information table according to the file name with the unverified status and the file receiver information; and determine the file transfer difference information according to the obtaining result of the corresponding file receiving information.
[0109] In some embodiments of the present application, the file verification result feedback module 340 is specifically configured to: if the obtaining result is that the corresponding file receiving information is obtained, update the corresponding file status information to the verified status in the file sending information table; if the obtaining result is that the corresponding file receiving information is not obtained, update the corresponding file status information to the retransmission required status in the file sending information table.
[0110] In some embodiments of the present application, the file verification result feedback module 340 is specifically configured to: screen out the file information with the file status information being the retransmission required status from the file sending information table as the file transfer difference information.
