Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a file transfer method, apparatus and device. Background Technology

[0002] File transfer refers to the process of transferring a file from the sending device to the receiving device.

[0003] In related technologies, each file to be transmitted has its corresponding verification file. The verification file stores the verification information for the file to be transmitted. When transmitting files, the sending device needs to send the file to be transmitted, along with its corresponding verification file. Correspondingly, the receiving device needs to receive the file sent by the sending device and its corresponding verification file, and verify the received file based on the verification information stored in the verification file. However, when there are many files to be transmitted, the sending device needs to send multiple files to be transmitted, along with multiple verification files corresponding to those files. Similarly, the receiving device needs to receive multiple files and their corresponding verification files. This file transmission process takes a long time, resulting in low file transmission efficiency. Summary of the Invention

[0079] 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 apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0080] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0081] To facilitate understanding, let's first combine Figure 1 The application scenarios provided in the embodiments of this application are described. Figure 1 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. Please refer to [link / reference]. Figure 1 It includes a first device, a storage device, and a second device.

[0082] The first device is a file sending device used to send the file to be transmitted. The first device sends the file to be transmitted to a storage device, and also sends a verification file for the file to be transmitted to the storage device. The storage device can provide temporary storage services for the file to be transmitted and the corresponding verification file. For example, the storage device can be a storage server. The second device is a file receiving device used to receive the file sent by the first device. The second device downloads the file sent by the first device and the corresponding verification file from the storage device, and verifies the received file according to the verification information stored in the verification file. The first and second devices can be terminal devices such as computers.

[0083] In related technologies, each file to be transmitted has a verification file. For example... Figure 2 As shown, Figure 2 This is a diagram illustrating the correspondence between the file to be transmitted and the verification file in existing technology. Please refer to [link / reference]. Figure 2The verification information for file 1 to be transferred is stored in verification file 1, the verification information for file 2 to be transferred is stored in verification file 2, and so on, until the verification information for file N to be transferred is stored in verification file N. Therefore, during file transfer, the number of verification files that need to be transferred between the first and second devices is the same as the number of files to be transferred. The large number of files that need to be transferred between the first and second devices results in a long transfer time and low file transfer efficiency.

[0084] To address the aforementioned technical problems, the file transfer method provided in this application stores the verification information of N files to be transferred in the same batch in the same verification file. For example... Figure 3 As shown, Figure 3 This is a diagram showing the correspondence between the file to be transmitted and the verification file provided in an embodiment of this application. Please refer to [link / reference]. Figure 3 The verification information 1 for file 1 to be transferred, the verification information 2 for file 2 to be transferred, ..., the verification information N for file N to be transferred are all stored in the same verification file. This method reduces the number of verification files, thus reducing the number of files that need to be transferred. Therefore, it shortens the file transfer time and improves file transfer efficiency.

[0085] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0086] Figure 4 This is a flowchart illustrating a file transfer method provided in an embodiment of this application. Please refer to... Figure 4 The method may include:

[0087] S401, The first device determines the N data files to be transmitted and the file names of the N data files.

[0088] The data file is the file that needs to be transferred from the first device to the second device; that is, the data file is the file to be transferred.

[0089] In this embodiment, the first device and the second device pre-agree on a naming rule for the data files. The first device automatically names the data files according to the naming rule and determines the files to be transmitted in each batch based on the names of the data files. For example, the first device can determine the file name of the data file based on its generation time, and can identify N data files generated within the same time period as the same batch of files to be transmitted. Here, N is an integer greater than or equal to 1.

[0090] In one possible implementation, the filename of a data file can consist of a naming part and a sequence number part. The naming part indicates the file type, creation time, etc., of the data file. The sequence number part indicates the creation order of N data files within a certain time period. The filenames of the N data files can be determined as follows: a first device determines the naming part and the sequence number part of the N data files based on their creation times; the naming parts of the N data files are the same, and the sequence numbers are all different; for any given data file, the first device combines the naming part and the sequence number part to obtain the filename of the data file.

[0091] Specifically, the first device can send a data file once per minute. Data files generated within the same minute have the same name part. All data files with the same name part belong to the same batch of data files. The first device can generate the name part of the data files at one-minute intervals. The sequence number part of the data files is arranged in ascending order of natural numbers according to the order in which the data files were generated.

[0092] For example, the naming part of a data file can be data_202102071049. Here, "data" indicates the file type. "20210207" indicates the year, month, and day the data file was generated. "1049" indicates the time the data file was generated. The sequence numbers are arranged in ascending order. If the number of data files generated within the same minute is 10 or less (including 10), the sequence number is a natural number from 0 to 9. If the number of data files generated within the same minute is 100 or less (including 100), the sequence number is a natural number from 00 to 99. Similarly, if the number of data files generated within the same minute is 1000 or less (including 1000), the sequence number is a natural number from 000 to 999. The naming part and the sequence number are connected by an underscore to form the file name of the data file. Assuming the number of data files generated at the current moment is greater than 10 and less than or equal to 100, the file names of the data files can be from data_202102071049_00.tar.gz to data_202102071049_99.tar.gz.

[0093] S402. The first device obtains the verification information of each data file and gets N verification information.

[0094] It should be understood that during file transfer, after the receiving device receives the data file and its corresponding verification information, it verifies the data file based on the verification information. In other words, the verification information refers to the information used to verify the data file.

[0095] In this embodiment, the first device generates verification information for each data file and sends the verification information to the second device along with the data file. After receiving the data file and the corresponding verification information, the second device verifies the integrity of the received data file based on the verification information.

[0096] In this embodiment, the first device uses a file encryption algorithm to generate verification information for the data file. The file encryption algorithm includes, but is not limited to, MD5 and hash algorithms.

[0097] S403. The first device generates a verification file based on the file names of N data files and N verification information.

[0098] The verification file is a file that stores verification information.

[0099] In this embodiment, the N verification messages of N data files generated in the same batch are stored in the same verification file. That is, one verification file stores N verification messages. The verification file can be generated as follows: the first device generates N verification records based on the file names of the N data files and the N verification messages. Each verification record includes a file name and the corresponding verification message. The verification file is generated based on the N verification records. The verification file includes N verification records, and an end identifier is included at the end of the verification file.

[0100] In one possible implementation, the verification record may include the filename of the data file and the corresponding verification information. The filename and verification information in each verification record are separated by a delimiter. For example, the delimiter can be a space, comma, or pause mark. N verification records for N data files in the same batch are stored in the same verification file. An end identifier is added to the end of the verification file. For example, the end of the verification file can be the last line of the verification file. The end identifier can be "END". That is, "END" can be added to the last line of the verification file to indicate the end of the storage of verification records for this batch.

[0101] One possible implementation is to generate the verification file as follows: determine the order of N verification records based on the filenames of N data files; generate the verification file according to the order and the N verification records; in the verification file, the N verification records are arranged in the order, with a separator between each pair of adjacent verification records. For example, the separator can be a newline character, meaning that each pair of adjacent verification records can be stored in two adjacent lines in the verification file.

[0102] For example, the verification file can store N verification records corresponding to N data files, with one verification record per line. The N verification records are arranged in ascending order according to the file name sequence of the data files.

[0103] In one possible implementation, the filename of the verification file is the same as the naming part of the filename of the batch of data files. For example, the filename of the verification file could be data_202102071049.chk.

[0104] S404. The first device sends N data files and a verification file to the file storage device.

[0105] File storage devices can temporarily store data files and corresponding verification files. For example, a file storage device can be a storage server.

[0106] It should be understood that the first device sends the data file and the corresponding verification file to the file storage device so that the second device can download the data file and verification file from the file storage device.

[0107] In this embodiment, when the first device sends a file to the storage device, it first sends N data files and then sends the corresponding verification file for the N data files to avoid missing data files.

[0108] The file transfer method provided in this application involves a first device determining N data files to be transferred and their file names, obtaining verification information for each data file to obtain N verification information entries, generating a verification file based on the file names and verification information entries, and then sending the N data files and the verification file to a file storage device. In this process, the verification information for the N data files is stored in the same verification file, reducing the number of files the first device needs to send and improving file transfer efficiency.

[0109] Based on any of the above embodiments, the following, in conjunction with Figure 5 The process of the second device retrieving data files from the file storage device is described.

[0110] Figure 5 This is a flowchart illustrating another file transfer method provided in an embodiment of this application. Please refer to... Figure 5 The method may include:

[0111] S501, The second device retrieves the verification file from the file storage device.

[0112] In this embodiment, the first device sends a data file and a verification file to a storage device. The storage device temporarily stores the data file and the verification file. The second device downloads the data file and the verification file from the storage device. Specifically, when downloading files from the storage device, the second device downloads the verification file first and the data file last to ensure the integrity of the downloaded verification file.

[0113] S502. The second device performs integrity verification on the verification file and obtains the verification result.

[0114] Integrity verification refers to checking whether the obtained file is complete.

[0115] In actual file transfer, there may be situations where the verification file is downloaded by the second device before it has been completely stored on the storage device. In this case, the verification file downloaded by the second device will be an incomplete verification file.

[0116] In one possible implementation, the integrity of the verification file can be verified as follows: the second device determines whether there is an end identifier at the end of the verification file; if so, the second device determines that the verification result indicates that the verification file is complete; if not, the second device determines that the verification result indicates that the verification file is not complete.

[0117] Specifically, if the verification file is complete, proceed to step S503. If the verification file is incomplete, the second device retrieves the verification file from the storage device again and verifies its integrity; until the second file is complete, proceed to step S503.

[0118] S503. When the verification result indicates that the verification file is complete, the second device obtains the file name of the verification file.

[0119] S504. The second device retrieves N data files corresponding to the verification file from the file storage device based on the file name of the verification file.

[0120] In this embodiment, the filename of the verification file has the same naming part as the filenames of the corresponding N data files. After obtaining the filename of the verification file, the second device can retrieve the data files with the same naming part as the verification file from the storage device. That is, the second device can retrieve the N data files corresponding to the verification file from the storage device based on the filename of the verification file.

[0121] In actual file transfer, the N data files corresponding to the verification file can be obtained in the following way: the second device obtains the first file name of the verification file; the second device identifies the data files in the file storage device whose names are the same as the first file name as N data files.

[0122] The first file indicates the verification file that should be acquired according to the file generation order. For example, after the second device completes the acquisition of the verification file data_202102071049.chk and the corresponding data file, the verification file that should be acquired according to the file generation order is data_202102071050.chk. At this time, the first file is the verification file data_202102071050.chk, and the first file name is data_202102071050.chk.

[0123] After the second device obtains the first file and its name, it downloads all data files whose names are the same as the first file from the storage device. These data files are the N data files corresponding to the first file.

[0124] S505. The second device performs verification processing on the corresponding data file according to the verification file.

[0125] It should be understood that the verification information in the verification file is used to verify the corresponding data file. The data file can be verified as follows: the second device obtains N verification information entries from the verification file; the second device then uses these N verification information entries to perform verification processing on the corresponding data file.

[0126] For example, the second device can perform verification processing on the data file corresponding to the filename stored in the first line of the verification file using the verification information stored in the first line of the verification file. Similarly, the second device can perform verification processing on the data file corresponding to the filename stored in the nth line of the verification file using the verification information stored in the nth line of the verification file, where 0... <n≤N。

[0127] The file transfer method provided in this application involves a second device retrieving a verification file from a file storage device and performing integrity verification on the verification file to obtain a verification result. When the verification result indicates that the verification file is complete, the second device retrieves the filename of the verification file and, based on the filename, retrieves N data files corresponding to the verification file from the file storage device. The second device then performs verification processing on the corresponding data files according to the verification file. In this process, the verification information of the N data files is stored in the same verification file, reducing the number of files the second device needs to receive and improving file transfer efficiency.
