Description

Data transmission method and related equipment based on foundation system

Technical Field

The present invention relates to an interaction system, and in particular, to a data transmission method and related devices based on a fund system.

Background

With the development of financial services, more and more sales services of financial products are circulated in the market. Meanwhile, sales service of financial products, such as fund sales service, is also actively developed. The fund sales company plays a bridge work between the fund company and the user, and needs to send the transaction information of the user to the fund company for transaction, and meanwhile, the transaction information fed back by the fund company is received and arranged. This was done early by manual billing, but with the development of technology, foundation marketing systems became the primary processing system. The business process inside the general foundation sales company is complex, and massive data needs to be processed. If the fund expense company develops the expense system by itself, a great deal of manpower and financial effort is required. Therefore, purchasing a third party's foundation expense system is a primary means of foundation expense companies.

When data is transmitted between a fund marketing company and a fund company, text in a TXT format is generally adopted for transmission in order to realize light weight of data transmission. The transmitted text is largely divided into an index file and a data file. The data file is composed of a plurality of transmission data, and the transmission data comprises a file identifier, a file version number, a file creator, a file receiver, a date, the number of files, a file name …, a file end identifier and the like. In the existing data transfer process, the meaning represented by each line of data and the data length are defined, for example, the first row of data is a file identifier, the length is 8 bytes, and the seventh row to the ninth row do not set a character string with the data length. Generally, "OFDCFIDX" is set as a file identifier, the length is defined as 8 bytes, and the file version number is 22, which does not satisfy the predefined 8 bytes, so that space or zero is adopted for filling. Wherein, "OFDCFEND" is the end of file identification. The data file is formed by splicing a plurality of data messages, and the data messages comprise a file identifier, a file version number, a file creator, a file receiver, a date, a summary list number, a file type code, a sender, a receiver, a field number, a field name, a record number, a record and a file end identifier. In the data file, starting from the first byte, and counting 8 bytes later, the starting point identification of the data file is obtained, and the starting point identification in the data file is the same as the starting point identification in the index file. Starting from the last byte of the data file, the last eight bytes are counted to obtain the end identification of the data file, and the end identification in the data file is the same as the end identification in the index file. For convenience of presentation, three fields of the foundation code, the unit red and the red time are selected for presentation, and the field lengths of the three fields are 6 bytes, 16 bytes and 8 bytes respectively. If the reddening content reflected by a record of a certain data file is: "Fund 000120 0.45 yuan per serving at 7.1.1, then the data presented for the corresponding three fields are presented as: 000120000000000000004520210701. if the content of the score reflected by a certain record is: "foundation 000223 was 1.50 yuan per serving at 7.1.1, then the data presented in the corresponding three fields are presented as: 000223000000000000015020210701. since there are only two records and the corresponding byte length of the record is 16, it is necessary to make up with a space or zero. The present embodiment uses zero padding.

Therefore, the byte length of the existing scheme is preset and cannot be adjusted, and the insufficient part needs to be complemented by zero or space, so that the whole file is bulky and inconvenient to transmit. In addition, during analysis, the length of each byte needs to be recorded, so that accurate analysis can be realized, and if the set byte length changes, the analysis program needs to be rewritten, so that resource waste is caused.

As shown in fig. 3, the present embodiment provides a data transmission method based on a fund system, which includes the following steps:

S10, acquiring an information file to be transmitted, wherein the information file comprises a plurality of field data.

Specifically, the foundation company end generates various information files to be transmitted to the foundation sale end in the interaction process with the foundation sale end and in the operation process of the foundation company end. Taking a common scoring example, the end of the fund company needs to send the scoring result corresponding to each purchased fund of each user in the settlement period to the end of the fund service every other settlement period. Also, for example, clearing, when a user plans to stop buying a certain fund, the fund company needs to transmit the user's revenue during this period to the fund sales company. The information transmitted from the end of the fund company to the end of the fund sale is referred to as an information file in this embodiment.

The information file is composed of a plurality of pieces of information with specific operation information, time and the like, and the content of each piece of information is represented by character segment data.

S20, determining a coding identifier and a coding value corresponding to each field data according to a preset coding mapping table to obtain a plurality of first coding groups.

Specifically, a coding mapping table is preset, in which a corresponding coding identifier is set for each field type of field data, and a corresponding coding value is set for different field contents under each field type. As shown in fig. 4, the code corresponding to the "file type" is identified as "1"; the code mark corresponding to the file version number is 2; the code identifier corresponding to the file creator is 3; the code mark corresponding to the file receiver is 4; the code corresponding to the date is marked as 5; the code mark corresponding to the summary table number is '6'; the code identification corresponding to the file type code is 7; the code identification corresponding to the sender is 8; the code corresponding to the receiver is identified as 9; the code label corresponding to the field number is 10; the code corresponding to the "fund code (FundCode)" is identified as "11"; the code label corresponding to the unit red (DividendPerUnit) is 12; the code corresponding to the red separating time (DIVIDENTDATE) is identified as 13; the code corresponding to the "record number" is identified as "14", which is the number of information in the reddening file, namely, the information specifically related to reddening; the code corresponding to the "extension field 1" is identified as "500"; the code corresponding to "extension field 2" is identified as "501"; the code corresponding to the check protocol is identified as 998; the code corresponding to the "check bit" is identified as "999".

For example, a certain field data has a field type of date, a specific field content is 03 in 2020, a code identifier corresponding to that one piece of data is 5, and a code value corresponding to the field content is 20200303. The field type is a file receiver, a corresponding code value is preset for each file receiver (namely, a foundation sale terminal) contacted with the foundation company, the code mark corresponding to the file receiver is 4, the code value corresponding to the foundation sale terminal a is 1, and the code value corresponding to the file receiving terminal in the information file required to be sent to the foundation sale terminal a is 1.

Therefore, after the field data in the information file are obtained, the coding identifier and the coding value corresponding to the field data are determined according to the field type and the field content of each field data, and the first coding group corresponding to each field data is obtained. After determining the first code groups corresponding to all the field data, a plurality of first code groups can be obtained.

In this embodiment of the present disclosure, the first code group corresponding to each field data includes a code identifier and a code value corresponding to the field data, where the code identifier and the code value may be formed by combining characters such as arabic numerals and letters. To distinguish between the coded identifiers in the first coded set and the coded set, in one implementation, the coded identifiers may be used as numbers and the coded values may be used in letters, i.e., the coded identifiers and the coded values may be in different formats. In another implementation, a pointer is used to connect the coded identifier and the coded value, where the pointer is a connection symbol with a pointing property, such as a colon, arrow, dash, etc.

S30, determining a data coding group corresponding to the file format in the first coding group according to each preset file format and the coding mapping table, and taking the data coding group and the format coding group corresponding to the file format as a second coding group corresponding to the file format.

Specifically, the files transmitted to the fund company end are generally composed of two files, one is an index file and the other is a data file. Compared with the data file, the index file is smaller, is convenient for the base metal selling end to read and retrieve, and has larger data file and detailed information. The index file and the data file are obtained based on the original information file, and the content contained in the index file and the data file is different. That is, the file format of the index file and the file format of the data file, that is, the index file format and the data file format, determine the corresponding different first encoding arrays.

Therefore, according to the preset file format, the data coding group corresponding to the file format in the first coding group is determined. Specifically, the data encoding group includes an index file data group and a data file encoding group. And determining a first coding group corresponding to the index file as an index file coding group according to the index file format, and determining the first coding group corresponding to the data file as a data file coding group according to the data file format. Of course, if other files, such as system parameters, are added to the original index file and data file at the end of the fund company and the end of the fund sale, the other files can be used as another file, so as to generate the corresponding data coding set.

In the conventional manner, the initial positions of the index file and the data file which are generated last are directly written with characters of the index file or the data file, and in order to reduce the volume of the file, in this embodiment, the coding mapping table is set with coding identifiers and coding values corresponding to different file formats in advance, for example, the coding identifier corresponding to the file format is 1, the coding value corresponding to the file format of the index file is 01, and the coding value corresponding to the file format of the data file is 02. After determining the file format, determining the corresponding code identification and code value, and generating a format code group by adopting a mode of generating a first code group. And then the data coding group and the format coding group are used as an index file or a second coding group corresponding to the data file.

S40, classifying the second coding group according to a preset classification rule to obtain a plurality of coding group sets.

Specifically, a classification rule is preset for classifying the second coding group, and the purpose of classification is mainly to combine the second coding groups with different importance degrees and different types, so that the subsequent foundation sale terminal can be conveniently processed.

In the first mode of this embodiment, all the second code groups are directly used as one category, and one code group set is obtained.

In another embodiment, the number of code sets and which ones are a code set are defined by the needs of the end of the fund company. For example, as shown in fig. 5, a second code group corresponding to "file type", "file version number", "file creator", "file receiver", "field number", "record number" is used as the code group set.

S50, for each coding group set, integrating the coding group set according to a preset integration rule to obtain a target coding sequence corresponding to the coding group set.

Specifically, the splitting process is performed on the second code group in the code group set in units of the code group set. An integration rule is preset, and then each second code group in the code group is processed through the integration rule. Wherein, the second code groups in the code group are scattered, so a mode is needed to integrate the second code groups together to obtain the target code sequence.

In a first implementation manner of this embodiment, for each of the code group sets, first, according to a preset ordering rule, the second code group in the code group set is ordered to obtain a first code sequence. As shown, for the first code group set, the preset ordering order is: "File type", "File version number", "File creator", "File recipient", "field number", "record number"; for the second code group set, the preset ordering order is: "Foundation code (FundCode)" "DividendPerUnit (units of red)" "DIVIDENTDATE (times of red)".

And then, separating the second coding group in the first coding sequence according to a preset separator to obtain a target coding sequence corresponding to the first coding sequence. A plurality of separators are preset, and in this embodiment, the separators include null characters, line separators, and other special characters, and the special characters include "|" and the like. The null character is 0x00 in ASCII code, representing a null character. The second code group in the first code sequence is separated by a separator, which is added substantially before or after the second code group.

In another implementation, to increase ease of integration of the target coding sequence to be subsequently incorporated, in this embodiment, the separators include intra-set separators and inter-set separators. As the name implies, intra-group separators are used to separate a first coding group within a coding group set, while inter-group separators are used to separate coding group sets.

Firstly, modifying a separator of a second coding group in the file coding sequence according to a preset separator in the group for each first coding sequence obtained after sequencing to obtain a second coding sequence corresponding to the first coding sequence. In fig. 5, in order to represent the null character, a box is used for illustration, and the intra-group separator used is the null character.

And then adding a preset inter-group separator to the tail end of the second coding sequence to obtain a target coding sequence corresponding to the second coding sequence. Therefore, after the foundation exchange end obtains the transmission file and analyzes the transmission file to the target coding sequence, the data can be accurately split according to the group separator, and individual reading and independent analysis are not needed.

Further, in order to facilitate the foundation marketing company to conveniently and rapidly locate the different coding group sequences, the component separator adopted in the embodiment is a line separator.

The existing scheme lacks a checking mechanism for data transmitted by a foundation company end, so that the error risk is reduced in order to improve the authenticity of the data, and the checking mechanism is added in the process of generating a target coding sequence.

First, for each first code sequence, according to a preset intra-group separator, separating a second code group in the first code sequence to obtain a second code sequence corresponding to the first code sequence. The manner in which the component separator is added may be referred to in the foregoing, and will not be described in detail herein.

And then calculating the second coding sequence according to a preset check rule to obtain check bits corresponding to the second coding sequence. A check rule is preset and used for encrypting the second coding sequence to obtain check bits. The common check rule is to directly set a check protocol, the check protocol is implemented by adopting an encryption algorithm, such as md5 algorithm and SHA1 algorithm, the second coding sequence is used as data to be encrypted, and the check protocol is adopted to carry out encryption calculation on the second coding sequence to obtain check bits corresponding to the check protocol. However, the encryption sequence obtained by the general verification protocol is longer, even longer than the encrypted content, and the length of the target coding sequence is increased. Therefore, in this embodiment, the check rule includes a check protocol and an extraction rule. And firstly, encrypting the second coding sequence by adopting a check protocol to obtain an encrypted sequence corresponding to the second coding sequence. And then extracting a specific position and a character with a specific length in the encryption sequence as check bits according to the extraction rule. In fig. 5, the verification algorithm is md5, and the extraction rule is that the first four bits are extracted, so that the first and second code sequences are corresponded, and the encrypted sequence obtained after encryption is 3446630d0fe 0c0dfd925fc47f7d0a 4' and the corresponding verification bit is 3446.

And adding a check mark in the code mapping table in advance to obtain a check bit, and generating a check code group corresponding to the second code sequence according to the check mark corresponding to the check rule and the check bit. The check mark comprises a check protocol mark and a check bit mark, for example, the check code group in fig. 5 is a combination of two code groups, and comprises a check mark code group formed by the check mark and a check value thereof, and a check value code group formed by the check bit mark and the check bit, wherein the generation of the check mark code group and the check value code group can be generated in the manner of generating the first code group as described above, and the description is omitted herein.

And adding the check code group to the second code sequence to obtain a third code sequence. The set of check codes may be located at the first, end, or other position of the second code sequence, and is not limited herein, and fig. 5 depicts adding it to the end of the second code sequence. It is noted that since the check code set is also a code set, the second code set at the end in the second code sequence should be added to the intra-set delimiter at the back end before being added to the end of the second code sequence. This step may be performed at the time of generating the second coding sequences, i.e. when intra-group separators are added, which are set at the end of each second coding group. In addition, when the check mark code group and the check bit code group are added to the second code sequence, an intra-group separator can be added between the two code groups for separation.

And finally, adding a preset inter-group separator to the tail end of the third coding sequence to obtain a target coding sequence corresponding to the second coding sequence. By adding the component separator, different coding group sets are separated, and multiple target coding group sequences can be read at the same time at the subsequent foundation terminal, so that the reading rate is improved.

S60, according to a preset arrangement rule, arranging the target coding sequence to obtain a transmission file corresponding to the information file.

Specifically, an arrangement rule is preset, and as each code group set can obtain a target code sequence, and a transmission file is a set of different target code sequences, the arrangement rule is to arrange a plurality of target code rules to obtain a file arranged according to a certain rule, and the file can be an index file or a data file. After the data file and the index file are obtained, a transmission file corresponding to the information file obtained at the beginning is obtained.

Finally, the transmission file can be transmitted to the foundation terminal based on the communication connection between the foundation terminal and the foundation terminal.

After the fund marketing end obtains the transmission file, for each transmission file in each file format, extracting a second coding group in each target coding sequence in the transmission file according to the position of the check coding group which is agreed with the fund company end in advance. And then, encrypting the second code group by adopting a verification protocol identical to that of the foundation company end to obtain a corresponding verification value. And finally, comparing the verification value with check bits in the check code group. If the two codes are the same, the second code group is analyzed according to the code mapping table which is the same as the end of the foundation company, and the required information file is obtained.

By comparing fig. 5 with fig. 6, the transmission file finally obtained by the scheme is obviously smaller, simpler, more flexible and safer.
