[0002] In the financial sector, as financial institutions expand and refine their operations, the demand for processing various documents is increasing. In this context, downloading massive amounts of invoices (such as expense reimbursement documents) provides a robust data foundation for budget planning and cost control. Therefore, accurately downloading these massive amounts of invoices is crucial for ensuring the efficient operation of financial institutions.

[0003] In traditional technology, when downloading massive amounts of invoice files, the files are typically compressed first, then the compressed package is sliced, and the slice positions are recorded to enable breakpoint transmission.

[0069] It should be noted that in the embodiments of this application, certain software, components, models and other existing solutions in the industry may be mentioned. These should be regarded as exemplary and are only intended to illustrate the feasibility of implementing the technical solution of this application. However, it does not mean that the applicant has used or necessarily used the solution.

[0070] The file download method provided in this application embodiment can be applied to, for example... Figure 1In the application environment shown, terminal 102 communicates with server 104 via a network. Terminal 102 sends query information associated with the set of invoice files to be downloaded to server 104; server 104 obtains the first attribute information of each invoice file to be downloaded in the set of invoice files, and determines the first storage path information of each invoice file in terminal 102 based on the query information and the first attribute information; obtains the second attribute information of each invoice file to be downloaded, and determines the metadata information of each invoice file to be downloaded based on the first storage path information and the second attribute information; sends the metadata information of each invoice file to terminal 102; terminal 102 downloads each invoice file to be downloaded sequentially from server 104 based on the metadata information of each invoice file to be downloaded. Terminal 102 refers to the terminal corresponding to downloading the invoice files, which can be, but is not limited to, various personal computers, laptops, smartphones, and tablets. Server 104 refers to the server used to store the invoice files to be downloaded, which can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0071] In one exemplary embodiment, such as Figure 2 As shown, a file download method is provided, which can be applied to... Figure 1 Taking the server-side as an example, the explanation includes the following steps:

[0072] Step S201: Receive query information sent by the terminal that is associated with the set of ticket files to be downloaded.

[0073] The set of invoice files to be downloaded refers to the collection of invoice files to be downloaded.

[0074] Among them, the invoice file to be downloaded refers to the invoice file that needs to be downloaded.

[0075] The query information refers to descriptive information used to filter a specific set of invoice files to be downloaded, such as "the set of invoice files with project number 123".

[0076] For example, the server receives a connection request sent by the terminal and verifies the identity information (such as username, password, and token) carried in the connection request according to a pre-set authentication mechanism to obtain the verification result. If the verification result meets the preset check result, the server establishes a network path with the terminal. Then, the server receives query information sent by the terminal associated with the set of tickets to be downloaded through the network path.

[0077] Step S202: Obtain the first attribute information of each ticket file to be downloaded in the set of ticket files to be downloaded, and determine the first storage path information of each ticket file to be downloaded in the terminal based on the query information and the first attribute information; the first attribute information of each ticket file to be downloaded is used to represent the file format information and file content information of the ticket file to be downloaded.

[0078] The first attribute information of each ticket file to be downloaded is used to represent the file format information and file content information of the ticket file to be downloaded.

[0079] Among them, file format information is used to represent the specific encoding and storage structure of different types of files, such as txt, pdf, jpg, etc.

[0080] The file content information is used to describe the content contained in the ticket file to be downloaded.

[0081] The first storage path information refers to the storage path information of each ticket file to be downloaded in the terminal.

[0082] For example, the server obtains the file format information and file content information of each document to be downloaded from the set of document files to be downloaded, as the first attribute information of each document to be downloaded; then, the server obtains the pre-constructed correspondence between query information, first attribute information and storage path information, and queries the correspondence based on the query information and first attribute information to obtain the storage path information corresponding to the query information and first attribute information, as the first storage path information of each document to be downloaded in the terminal.

[0083] Step S203: Obtain the second attribute information of each ticket file to be downloaded, and determine the metadata information of each ticket file to be downloaded based on the first storage path information and the second attribute information; the second attribute information of each ticket file to be downloaded includes at least the second storage path information of the ticket file to be downloaded on the server.

[0084] The second attribute information of each ticket file to be downloaded includes at least the second storage path information of the ticket file to be downloaded on the server.

[0085] The metadata information for each ticket file to be downloaded describes the attributes and characteristics of each ticket file, including the first storage path information of each ticket file in the terminal and the second storage path information of each ticket file in the server.

[0086] The second storage path information refers to the storage path information of the ticket file to be downloaded on the server.

[0087] For example, the server obtains the second storage path information of the ticket file to be downloaded on the server, as the second attribute information of each ticket file to be downloaded; then, the server combines the first storage path information and the second attribute information to obtain the metadata information of each ticket file to be downloaded.

[0088] Step S204: Send the metadata information of each ticket file to be downloaded to the terminal, so that the terminal can download each ticket file from the server in sequence according to the metadata information of each ticket file to be downloaded.

[0089] For example, the server sends the metadata information of each ticket file to be downloaded to the terminal through the network path between the server and the terminal; the terminal receives the metadata information of each ticket file to be downloaded sent by the server, and downloads each ticket file to be downloaded from the server in sequence according to the metadata information of each ticket file to be downloaded.

[0090] In the above file download method, the system first receives query information sent by the terminal that is associated with the set of invoice files to be downloaded. Then, it obtains the file format information and file content information of each invoice file to be downloaded in the set of invoice files to be downloaded, which serve as the first attribute information of each invoice file to be downloaded. Next, based on the query information and the first attribute information, it determines the first storage path information of each invoice file to be downloaded on the terminal. Then, it obtains the second storage path information of the invoice files to be downloaded on the server, which serves as the second attribute information of each invoice file to be downloaded. Based on the first storage path information and the second attribute information, it determines the metadata information of each invoice file to be downloaded. Finally, it sends the metadata information of each invoice file to be downloaded to the terminal, so that the terminal can download each invoice file to be downloaded sequentially from the server based on the metadata information of each invoice file to be downloaded. The above method has the following beneficial effects: For each document file in the set of documents to be downloaded, the first storage path information is determined based on the query information and the first attribute information, and the second attribute information of the document file to be downloaded is determined based on the second storage path information on the server. This provides more accurate metadata information, enabling the terminal to accurately download the document files and further improving the accuracy of downloading massive amounts of document files. In other words, by comprehensively considering the query information, the first attribute information, and the second attribute information, the accuracy of downloading massive amounts of document files is improved. Furthermore, in data analysis in the financial field, accurate downloading of document files ensures the accuracy of the downloaded documents, thereby improving the accuracy of the data analysis results obtained based on the document files, which in turn helps improve the accuracy of data analysis in financial enterprises.

[0091] In one exemplary embodiment, such as Figure 3As shown, step S202 above, based on the query information and the first attribute information, determines the first storage path information of each ticket file to be downloaded in the terminal, specifically including the following steps:

[0092] Step S301: Based on the query information, determine the root directory information of each ticket file to be downloaded in the terminal, and based on the first attribute information of each ticket file to be downloaded, determine the subdirectory information of each ticket file to be downloaded in the terminal.

[0093] Step S302: Based on the root directory information and subdirectory information of each ticket file to be downloaded, determine the first storage path information of each ticket file to be downloaded in the terminal.

[0094] The root directory information is used to represent the top-level directory of each ticket file to be downloaded in the terminal.

[0095] The subdirectory information is used to indicate the directory under the root directory information of each ticket file to be downloaded in the terminal.

[0096] For example, the server obtains the parameter information carried in the query information and determines the root directory information of each document file to be downloaded in the terminal based on the parameter information. Then, the server determines the subdirectory information of each document file to be downloaded in the terminal based on the file format information and file content information of each document file to be downloaded. Then, the server combines the root directory information and subdirectory information of each document file to be downloaded according to a preset combination method to obtain combined directory information, which serves as the first storage path information of each document file to be downloaded in the terminal.

[0097] For example, the server retrieves the parameter information "purchase invoice" from the query information and determines the root directory information "F:\Purchase Invoice" for each invoice file to be downloaded in the terminal based on this parameter information. Next, the server determines the subdirectory information "pdf\Product Development Project" for each invoice file to be downloaded in the terminal based on the file format information "pdf" and the file content information "Product Development Project". Then, the server combines the root directory information and subdirectory information of each invoice file to be downloaded according to a preset combination method, and obtains the combined directory information "F:\Purchase Invoice\pdf\Product Development Project", which serves as the first storage path information for each invoice file to be downloaded in the terminal.

[0098] In this embodiment, the root directory information is determined by querying information, and the subdirectory information is determined by the first attribute information, so that each ticket file to be downloaded has a specific and accurate storage location, which makes it easier to find the file more accurately when downloading the file later and reduces the possibility of downloading other files by mistake.

[0099] In one exemplary embodiment, such as Figure 4 As shown, step S203 above, obtaining the second attribute information of each ticket file to be downloaded, specifically includes the following steps:

[0100] Step S401: Input each document file to be downloaded into a preset summary information processing model for summary extraction processing to obtain summary information for each document file to be downloaded.

[0101] Step S402: Obtain the file number and file data volume of each ticket file to be downloaded, as well as the second storage path information of each ticket file to be downloaded on the server, and use the summary information, file number, file data volume and second storage path information of each ticket file to be downloaded as the second attribute information of each ticket file to be downloaded.

[0102] Among them, the summary information processing model refers to the network model that can obtain the summary information of each ticket file to be downloaded using each ticket file to be downloaded, such as the MD5 (Message Digest Algorithm 5) model.

[0103] The abstract extraction process refers to the process of obtaining the abstract information of each document to be downloaded based on each document to be downloaded.

[0104] The summary information refers to the MD5 value.

[0105] The file number is a unique identifier that distinguishes the document to be downloaded.

[0106] The file data size is used to indicate the size of the ticket file to be downloaded.

[0107] For example, the server preprocesses each ticket file to be downloaded to obtain a preprocessed file corresponding to each ticket file; then, the server inputs the preprocessed file corresponding to each ticket file to be downloaded into a preset summary information processing model for summary extraction processing to obtain the summary information of the preprocessed file corresponding to each ticket file to be downloaded, which serves as the summary information of each ticket file to be downloaded; then, the server obtains the file number and file data volume of each ticket file to be downloaded, as well as the second storage path information of each ticket file to be downloaded on the server; then, the server uses the summary information, file number, file data volume, and second storage path information of each ticket file to be downloaded as the second attribute information of each ticket file to be downloaded.

[0108] In this embodiment, the summary information, file number, file data volume, and second storage path information of each ticket file to be downloaded are all used as the second attribute information of each ticket file to be downloaded. The entire process is combined with the download process, so that the downloaded files can be better recorded and tracked, which facilitates the subsequent processing.

[0109] In one exemplary embodiment, such as Figure 5 As shown, step S203 above, which determines the metadata information of each ticket file to be downloaded based on the first storage path information and the second attribute information, specifically includes the following steps:

[0110] Step S501: Determine the combination method between the summary information, file number, file data volume, first storage path information and second storage path information.

[0111] Step S502: According to the combination method, the summary information, file number, file data volume, first storage path information and second storage path information of each ticket file to be downloaded are combined to obtain the metadata information of each ticket file to be downloaded.

[0112] Among them, the combination method is used to represent the combination form between summary information, file number, file data volume, first storage path information and second storage path information, such as table combination method and text combination method.

[0113] For example, the server queries the correspondence between data types and combination methods based on the data types of the summary information, file number, file data volume, first storage path information, and second storage path information to obtain the combination method between the summary information, file number, file data volume, first storage path information, and second storage path information. Then, the server performs combination processing on the summary information, file number, file data volume, first storage path information, and second storage path information of each ticket file to be downloaded according to the combination method to obtain the metadata information of each ticket file to be downloaded.

[0114] In this embodiment, by combining the summary information, file number, file data volume, first storage path information and second storage path information of each document to be downloaded in a suitable way, more accurate metadata information can be obtained, which is beneficial to improving the accuracy of determining the metadata information of each document to be downloaded.

[0115] In one exemplary embodiment, such as Figure 6 As shown, step S202 above, obtaining the first attribute information of each document to be downloaded in the set of document documents to be downloaded, specifically includes the following steps:

[0116] Step S601: Obtain the file name information for each ticket file to be downloaded.

[0117] Step S602: Based on the file name information of each document to be downloaded, query the correspondence between the file name information and the file format information to obtain the file format information of each document to be downloaded.

[0118] Step S603: Parse each document file to be downloaded to obtain the file content information of each document file.

[0119] Step S604: The file format information and file content information of each document to be downloaded are both used as the first attribute information of each document to be downloaded.

[0120] The file name information is used to describe the name of each ticket file to be downloaded.

[0121] The correspondence between file name information and file format information is used to represent the association between the two. For example, the file name "a.txt" corresponds to the file format "txt".

[0122] Among them, parsing processing refers to the process of obtaining the file content information corresponding to each ticket file to be downloaded based on each ticket file to be downloaded.

[0123] For example, the server obtains the filename information of each invoice file to be downloaded; then, based on the filename information of each invoice file to be downloaded, the server queries the correspondence between the filename information and the file format information to obtain the file format information corresponding to the filename information of each invoice file to be downloaded, which is used as the file format information of each invoice file to be downloaded; then, based on the file format information of each invoice file to be downloaded, the server determines the parsing method of each invoice file to be downloaded, and performs parsing processing on each invoice file to be downloaded according to the parsing method, to obtain the file content information of each invoice file to be downloaded; finally, the server uses both the file format information and the file content information of each invoice file to be downloaded as the first attribute information of each invoice file to be downloaded.

[0124] In this embodiment, by performing a series of processes on each document file to be downloaded, accurate file format information and file content information can be obtained, which in turn can obtain more accurate first attribute information, thus improving the accuracy of determining the first attribute information of each document file to be downloaded.

[0125] In an exemplary embodiment, before sending the metadata information of each ticket file to be downloaded to the terminal, so that the terminal can download each ticket file from the server in sequence according to the metadata information of each ticket file to be downloaded, step S204 specifically includes the following: encrypting the metadata information of each ticket file to be downloaded to obtain encrypted metadata information of each ticket file to be downloaded.

[0126] The process involves sending the metadata information of each ticket file to be downloaded to the terminal, enabling the terminal to sequentially download each ticket file from the server based on its metadata information. Specifically, this includes: sending encrypted metadata information of each ticket file to the terminal; the terminal decrypting the encrypted metadata information of each ticket file to obtain its metadata information, and then sequentially downloading each ticket file from the storage location corresponding to the second storage path information of each ticket file on the server to the storage location corresponding to the first storage path information of each ticket file on the terminal based on its metadata information.

[0127] Encryption processing refers to the process of obtaining the encrypted metadata information corresponding to each document to be downloaded based on its metadata information.

[0128] Encrypted metadata information refers to metadata information that has undergone encryption processing.

[0129] Decryption processing refers to the process of obtaining the metadata information corresponding to each document to be downloaded based on the encrypted metadata information of each document to be downloaded.

[0130] For example, the server determines the encryption algorithm corresponding to the metadata information of each ticket file to be downloaded, and encrypts the metadata information of each ticket file to be downloaded according to the encryption algorithm to obtain the encrypted metadata information of each ticket file to be downloaded; then, the server sends the encrypted metadata information of each ticket file to be downloaded to the terminal; the terminal receives the encrypted metadata information of each ticket file to be downloaded sent by the server, and decrypts the encrypted metadata information of each ticket file to be downloaded to obtain the metadata information of each ticket file to be downloaded; then, the terminal extracts the first storage path and second storage path information of each ticket file to be downloaded according to the metadata information of each ticket file to be downloaded, and downloads each ticket file to be downloaded sequentially from the storage location corresponding to the second storage path information of each ticket file to be downloaded in the server to the storage location corresponding to the first storage path information of each ticket file to be downloaded in the terminal according to the first storage path information of each ticket file to be downloaded.

[0131] In this embodiment, by encrypting the metadata information of each ticket file to be downloaded, it can be ensured that the metadata information of each ticket file to be downloaded is not tampered with, which helps to improve the security and integrity of the metadata information of each ticket file to be downloaded and ensures the stability of the download process of each ticket file to be downloaded.

[0132] In one embodiment, such as Figure 7 As shown, another file download method is provided, which can be applied to... Figure 1 Taking the server-side as an example, the explanation includes the following steps:

[0133] Step S701: Receive query information sent by the terminal that is associated with the set of ticket files to be downloaded.

[0134] Step S702: Obtain the file name information of each invoice file to be downloaded; based on the file name information of each invoice file to be downloaded, query the correspondence between the file name information and the file format information to obtain the file format information of each invoice file to be downloaded.

[0135] Step S703: Parse each document file to be downloaded to obtain the file content information of each document file.

[0136] Step S704: The file format information and file content information of each document to be downloaded are both used as the first attribute information of each document to be downloaded.

[0137] Step S705: Based on the query information, determine the root directory information of each ticket file to be downloaded in the terminal, and based on the first attribute information of each ticket file to be downloaded, determine the subdirectory information of each ticket file to be downloaded in the terminal.

[0138] Step S706: Based on the root directory information and subdirectory information of each ticket file to be downloaded, determine the first storage path information of each ticket file to be downloaded in the terminal.

[0139] Step S707: Input each document file to be downloaded into a preset summary information processing model for summary extraction processing to obtain summary information for each document file to be downloaded.

[0140] Step S708: Obtain the file number and file data volume of each ticket file to be downloaded, as well as the second storage path information of each ticket file to be downloaded on the server.

[0141] Step S709: The summary information, file number, file data volume, and second storage path information of each ticket file to be downloaded are all used as the second attribute information of each ticket file to be downloaded.

[0142] Step S710: Determine the combination method between the summary information, file number, file data volume, first storage path information and second storage path information.

[0143] Step S711: According to the combination method, the summary information, file number, file data volume, first storage path information and second storage path information of each ticket file to be downloaded are combined to obtain the metadata information of each ticket file to be downloaded.

[0144] Step S712: Send the metadata information of each ticket file to be downloaded to the terminal, so that the terminal can download each ticket file from the server in sequence according to the metadata information of each ticket file to be downloaded.

[0145] The above-described file download method achieves the following beneficial effects: For each document file in the set to be downloaded, the first storage path information is determined based on query information and first attribute information, and the second attribute information of the document file to be downloaded is determined based on the second storage path information on the server. This provides more accurate metadata information, enabling the terminal to accurately download the document files and further improving the accuracy of downloading massive amounts of document files. In other words, by comprehensively considering query information, first attribute information, and second attribute information, the accuracy of downloading massive amounts of document files is improved. Furthermore, in data analysis in the financial field, accurate downloading of document files ensures the accuracy of the downloaded documents, thereby improving the accuracy of data analysis results obtained based on document files, and ultimately contributing to improved data analysis accuracy for financial enterprises.

[0146] To more clearly illustrate the file download method provided in this disclosure, a specific embodiment is given below for detailed description. In one embodiment, as follows... Figure 8 As shown, this application also provides a method for downloading massive amounts of files, which can be applied to... Figure 1 The server-side component specifically includes the following:

[0147] 1. The server generates full file metadata information for each individual file and returns it to the client.

[0148] 2. The client retrieves individual files from the server one by one, treating each file as an atom.

[0149] 3. To avoid impacting normal business operations, the client only retrieves one atomic file at a time.

[0150] 4. Even if not all files have been completely written to the client, the already written data can still be viewed and used in advance.

[0151] 5. If a file fails to load on the client, incrementally retrieve the files that failed.

[0152] The full file metadata information includes information such as the file path on the client and server sides, the file's unique identifier, file name, file size, and MD5 hash, which is generated based on the basic information of a single file stored on the server side.

[0153] The root directory for client-side file storage is a parameter provided when the client initiates a query, while the storage path for each file is a subdirectory generated by the server based on information such as file format and file content.

[0154] In this context, a single file is considered an atom, specifically meaning that the transmission of a single file is considered a transaction. Only when the transmission of a single file is successful is the transaction considered successful.

[0155] "Deepening" here refers to the complete transfer and saving of the file.

[0156] The files are transferred one by one. Once a file has been transferred, it can be opened without waiting for other files.

[0157] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0158] In this embodiment, the following beneficial effects can be achieved: For each document file to be downloaded in the set of document files to be downloaded, the first storage path information is determined based on the query information and the first attribute information, and the second attribute information of the document file to be downloaded is determined based on the second storage path information on the server. This provides more accurate metadata information, enabling the terminal to accurately download the document files to be downloaded, further improving the accuracy of downloading massive amounts of document files. That is, by comprehensively considering the query information, the first attribute information, and the second attribute information, the accuracy of downloading massive amounts of document files is improved. In addition, in data analysis in the financial field, accurate downloading of document files can ensure the accuracy of the downloaded document files, thereby improving the accuracy of the data analysis results obtained based on the document files, which in turn helps to improve the accuracy of data analysis for financial enterprises. At the same time, even if the client files are not all downloaded, the downloaded data can still be seen and viewed in advance; if a file fails to download successfully, the unsuccessful file can be retrieved incrementally; it does not affect the normal business of the branch; and this method has a higher success rate when the download volume exceeds 100,000 and the download size reaches the terabyte level.
