Technical Field

[0001] The present invention relates to the field of file transmission, and in particular to a file transmission reading and writing method, device, equipment and storage medium. Background Art

[0002] If different systems interact using TXT files, a file communication protocol must define the file's content and format to ensure correct communication between the parties.

Changes to protocol files also require modifying the original code, limiting scalability. Furthermore, when there are too many protocol files to parse, parsing the corresponding files takes a significant amount of time, wasting manpower. Summary of the Invention

[0046] The embodiments of the present invention provide a file transmission reading and writing method, apparatus, device and storage medium.

[0047] The terms "first," "second," "third," "fourth," and the like (if any) in the description and claims of the present invention and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or apparatus.

[0048] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of the file transmission reading and writing method in an embodiment of the present invention includes:

[0049] 101. Receive a file transfer instruction;

[0050] In this embodiment, the file transfer instruction is {A: XXXX; B: YYY}, where A points to the address to be transferred and B points to the address to be extracted data.

[0051] Furthermore, after step 101 and before step 102, the following steps may be performed:

[0052] 1011. Determine whether the file corresponding to the file transfer instruction is in TXT format;

[0053] 1012. If it is not in TXT format, determine whether the file corresponding to the file transfer instruction has the protocol provisions;

[0054] 1013. If there is a protocol provision, read the protocol provision and process the file transfer instruction according to the protocol provision.

[0055] 1014. If there is no protocol provision, a transmission failure message is sent to the preset management port.

[0056] In steps 1011-1014, the format of the file to be transferred is determined. For protocol rule files that are not in structured TXT format, such as PDF or WORD files, the protocol rule content must be entered, or the protocol rule content must be filled in the protocol rule template and automatically imported into the protocol rule parser. If the parser has parsing protocol regulations for PDF, WORD, and other files, the protocol rule parser will execute according to the regulations. If the parser does not have parsing protocol regulations for PDF, WORD, and other files, a transmission failure message will be sent to the preset management port.

[0057] 102. Obtain a preset protocol rule file, access a business database corresponding to the file transfer instruction, and read a TXT file corresponding to the file transfer instruction;

[0058] In this embodiment, the protocol rule file is read and, depending on the protocol rule file, different methods are selected to enter the protocol rules into the protocol rule parser for parsing the transmission data. The service database corresponding to the file transfer instruction is accessed and the TXT file corresponding to the file transfer instruction is read to read and write data into the TXT file and the service database.

[0059] Among them, the protocol rule file includes: file name rule file, file header rule file, and file content rule file. The file name rule defines the specific generation rules of the TXT file name, and the specific protocol file can be generated or located according to the rule. The file header rule generally refers to the file header inside the TXT file, and the file header is generally a statistic of the file content. The file content rule refers to the truly meaningful business data in the TXT file. It includes the definition of the line break character, the definition of the field separator within the line, the type, length and meaning of the field in the line, the order of the fields in the line, and other information.

[0060] Furthermore, after step 102 and before step 103, the following steps may be performed:

[0061] 1021. According to the format setting of the protocol rule file, the data format of the TXT file is reorganized and processed to obtain a TXT file that complies with the format setting.

[0062] In step 1021, the data format of the TXT file is unified according to the format setting of the protocol rule file, where the arrangement order of each row and column can be that the valid header data is arranged in the front and the content data is arranged in the back.

[0063] 103. Determine whether the file transfer instruction is a data export instruction;

[0064] In this embodiment, it is necessary to check whether the file transfer instruction is reading or writing. The data export instruction exports data from the business database to a TXT file, while the non-data export instruction writes the TXT data of the TXT file into the business database.

[0065] Furthermore, at step 103 , the following steps may be performed:

[0066] 1031. The file transfer instruction includes: extracting an address, transmitting an address, and determining whether the file transfer instruction is a data export instruction includes:

[0067] 1032. Determine whether the transfer address of the file transfer instruction is a local path character string;

[0068] 1033. If it is a local path character string, determine the file transfer instruction as a data export instruction;

[0069] 1034. If it is not a local path character string, the file transfer instruction is determined not to be a data export instruction.

[0070] In steps 1031-1034, the file transfer instruction {A: XXXX; B: YYY}, where A points to XXXX, is the transfer address, and B points to YYY, the extraction address. A check is performed to determine whether XXXX is a path string to a local disk or storage device. If so, the TXT file to be transferred to the local path is a data export instruction. If not, it indicates that the file transfer instruction is a network link, and is not a data export instruction.

[0071] 104. If it is a data export instruction, export the business data in the business database according to the format of the preset business data table to obtain exported business data;

[0072] In this embodiment, the service data table format is not necessarily in the protocol format. The service data to be exported must be exported first and then converted into a TXT file.

[0073] 105. Reorganize the business fields of the exported business data according to the protocol rule file to obtain exported TXT data, and write the exported TXT data into a TXT file;

[0074] In this embodiment, the protocol format protocol rule decoder of the protocol rule file will write the entered protocol rule content into the protocol configuration database for use by the subsequent protocol field mapper. The protocol field mapper reads the configured protocol rule data from the protocol configuration database and dynamically generates a mapping relationship between the protocol rules and the business database table. The protocol field mapper automatically generates or updates the corresponding business data table by comparing the fields of the existing business database through the newly generated mapping relationship, determines the updated business data table as TXT data, and writes the TXT data into the TXT file.

[0075] Furthermore, at step 105 , the following steps may be performed:

[0076] 1051. Read the protocol field of the protocol rule file;

[0077] 1052. Match the protocol field with the business field of the exported business data to obtain a mapped business field set;

[0078] 1053. Based on the format setting of the protocol rule file, the data corresponding to the mapped business field set in the exported business data is formatted to obtain exported TXT data;

[0079] 1054. Write the exported TXT data into a TXT file.

[0080] In steps 1051-1054, the business system writes specific business data into the business database. The protocol field mapper retrieves the corresponding business data from the business database, converts it into the corresponding fields in the TXT file based on the mapping, and passes it to the protocol file reader generator. The protocol file reader generator converts the received data into TXT data and writes the TXT data into the TXT file.

[0081] 106. If it is not a data export instruction, copy the TXT characters of the TXT file to obtain a TXT string, perform field matching processing on the TXT string according to the protocol rule file to obtain a matching TXT string set, and write the data corresponding to the matching TXT string set in the TXT string into the business database.

[0082] In this implementation, you first need to copy the TXT characters in sorted order to get the TXT string of the content of the TXT file, match the protocol fields used for guidance in the protocol rule file with the TXT string one by one, get the matching TXT string in the TXT string, and then write the entity content corresponding to the matching TXT string into the business database according to the guidance mapping relationship.

[0083] 1061. According to the protocol rule file, performing field matching processing on the TXT string to obtain a matching TXT string set, and writing data corresponding to the matching TXT string set in the TXT string into the business database includes:

[0084] 1062. Read the protocol field of the protocol rule file;

[0085] 1063. Match the protocol field with the TXT string to obtain a matching TXT string set.

[0086] 1064. Based on the format setting of the protocol rule file, write the data corresponding to the matching TXT string set in the TXT string into the business database.

[0087] In steps 1061-1064, with the business database corresponding to the protocol data, the specific data is read from the TXT file and written to the business database. The protocol file reader generator reads the corresponding TXT file according to the file name mapping rules stored in the protocol field mapper. The protocol file reader generator passes the read data to the protocol field mapper, which parses the specific business data according to the corresponding mapping rules. The protocol field mapper writes the business data to the business database, where it can be read by the specific business system.

[0088] The present invention is used in the field of file transmission and parsing. It maps protocol files and database data tables in the form of configuration, so that file generation and parsing can be performed automatically and quickly without writing corresponding parsing and generation codes for specific protocol files, thereby improving the efficiency of parsing and generating files.
