[0023] In the development of gateway application system, the analysis of message format is a very important function. In the financial industry, various message formats are used when calling interfaces between institutions. For example, XML format, JSON format, fixed-length message format, ISO8583 message format, etc.

[0024] For easy-to-analyze messages, parsing can be quickly completed through public libraries without going through the gateway to handle a large number of logics. For complex messages such as fixed-length message format and ISO8583 message format, the gateway needs to save the message definitions of each message format in advance. When receiving a transaction message of a specified message format, the transaction number is first judged, and then the corresponding transaction message definition is found according to the transaction number, and then the complete message parsing is performed. This message parsing method is limited by the extraction logic of the transaction number of different message formats, and each new message format needs to rewrite the extraction logic of the transaction number, and involves code logic, which has certain difficulty in reading and understanding.

[0025] The present application determines the extraction logic of the transaction number to complete the parsing of the message without the aid of code. Please refer to Figure 1 , which is a gateway message secondary parsing method flowchart provided by the embodiment of the present application. The gateway message secondary parsing method specifically includes steps S101-S105.

[0026] In step S101, a plurality of first transaction numbers of parsed transaction messages in different message formats are obtained, and fields in each parsed transaction message are arranged in sequence.

[0027] Each first transaction number is composed of a plurality of different fields, which are parts of fields in the parsed transaction message composed of a plurality of fields. In some possible embodiments, the above-mentioned fields can be numbers, letters, combinations of numbers and letters, which are not described herein. In step S101, the message format of the parsed transaction message needs to cover the message format involved in the gateway message to determine the composition rule of the transaction number corresponding to each message format.

[0028] In step S102, each first transaction number is parsed by using a preset transaction template to obtain a plurality of field sequence numbers composed of all first transaction numbers.

[0029] The transaction template is not a transaction message configuration of a specified message format, but an incomplete special message configuration specially used for parsing the required fields of the transaction number. Through parsing of the transaction template, all fields required for the transaction number are obtained. In step S102, through parsing of the transaction template, a plurality of fields composed of all first transaction numbers are obtained, specifically, a sequence of corresponding fields in the parsed transaction message for each group of fields, and a field sequence number composed of a plurality of sequences. Please refer to Figure 2 which is a step S102 sub-step flowchart provided by the embodiment of the application. Parsing each first transaction number by using a preset transaction template to obtain a plurality of field sequence numbers composed of all first transaction numbers includes steps S1021-S1022.

[0030] In step S1021, fields composed of the parsed transaction message and the first transaction number are compared one by one to determine the same fields.

[0031] In step S1022, when the same fields are compared, the sequence number of the corresponding field in the parsed transaction message of the same field is recorded.

[0032] The field sequence number includes a plurality of sequences of the same fields in the parsed transaction message, and each sequence is separated by a separator in sequence. For example, in the ISO8583 message, after comparing the corresponding transaction number, the ISO8583 message 0, 3, 25 three same fields are compared, and the field sequence number of the ISO8583 message format is 0, 3, 25.

[0033] In step S103, a field list is configured in the transaction template according to each group of field sequence numbers and the transaction message definition corresponding to each first transaction number to obtain a configured transaction template.

[0034] The field list is used to map the relationship between a set of field sequence numbers and the message format of the transaction message definition. Please refer to Figure 3 which is a flowchart of sub-steps of step S103 provided by the embodiment of the present application. According to the transaction message definition corresponding to each set of field sequence numbers and each first transaction number, the field list configured in the transaction template includes steps S1031-S1032.

[0035] In step S1031, a mapping relationship group is obtained according to the message format of the transaction message definition, the field sequence numbers constituting the first transaction number, and the mapping relationship between the message format and the field sequence numbers.

[0036] The mapping relationship group includes a mapping item and a mapped item. The mapping item is the message format in the mapping relationship group, and the mapped item is the field sequence number in the mapping relationship group.

[0037] In step S1032, the mapping item in the mapping relationship group is placed in one column of the field list, and the mapped item in the mapping relationship group is placed in another column of the field list to obtain the field list.

[0038] In step S104, the second transaction number of the transaction message to be parsed is obtained according to the configured transaction template.

[0039] The transaction message to be parsed is composed of a plurality of fields to be parsed, and each field to be parsed is arranged in sequence. Please refer to Figure 4 which is a flowchart of sub-steps of step S104 provided by the embodiment of the present application. According to the configured transaction template, the second transaction number of the transaction message to be parsed is obtained, including steps S1041-S1044.

[0040] In step S1041, the message format of the transaction message to be parsed is obtained.

[0041] In step S1042, the field sequence numbers to be parsed are obtained in the field list of the configured transaction template according to the message format to be parsed.

[0042] In step S1042, after the message format of the transaction message to be parsed is obtained, the corresponding field sequence numbers need to be obtained to obtain the corresponding fields in the transaction message to be parsed, so as to obtain the second transaction number. Please refer to Figure 5 which is a flowchart of sub-steps of step S1042 provided by the embodiment of the present application. According to the message format to be parsed, the field sequence numbers to be parsed are obtained in the field list of the configured transaction template, including steps S10421-S10422.

[0043] Step S10421, compare the to-be-analyzed transaction message format with the message formats in the field list one by one.

[0044] In step S10421, the message formats in the field list are the message formats involved in the gateway message. In some possible embodiments, when the message format of the to-be-analyzed transaction message is not within the range of the message formats in the field list, the field list can be expanded by analyzing the transaction number corresponding to the message format, so as to achieve a universal effect.

[0045] Step S10422, when the same message format is found, the corresponding field sequence number in the field list is obtained as the to-be-analyzed field sequence number.

[0046] In step S10422, the fields in the to-be-analyzed transaction message are arranged in sequence, and when the same format is obtained, the corresponding field sequence number is also determined. That is, the fields constituting the second transaction number are also determined from the to-be-analyzed transaction message.

[0047] Step S1043, according to the to-be-analyzed field sequence number, the to-be-analyzed field in the to-be-analyzed transaction message is obtained.

[0048] In step S1043, after the field sequence number is obtained, the field in the corresponding field sequence number in the to-be-analyzed transaction message needs to be determined. Please refer to Figure 6 which is a sub-step flowchart of step S1043 provided by the embodiments of the present application. According to the to-be-analyzed field sequence number, the to-be-analyzed field in the to-be-analyzed transaction message is obtained, including steps S10431-S10432.

[0049] Step S10431, compare the to-be-analyzed field sequence number with the sequence of the to-be-analyzed field in the to-be-analyzed transaction message one by one.

[0050] Step S10432, when the same sequence is found, the to-be-analyzed field corresponding to the same sequence is obtained.

[0051] Step S1044, the to-be-analyzed fields are spliced in the order of the sequence in the to-be-analyzed field sequence number, and the second transaction number is obtained.

[0052] In step S1044, after all the fields constituting the second transaction number are obtained, all the fields need to be spliced in sequence. Specifically, the corresponding fields are spliced in the arrangement order of the sequence in the field sequence number, so as to obtain the second transaction number.

[0053] Step S105, according to the second transaction number, the message analysis of the corresponding transaction message definition is performed.

[0054] In step S105, after the second transaction number is acquired, the transaction message definition corresponding to the second transaction number is found in the existing transaction message definition. The essence of message analysis is the analysis of message analysis definition. After the transaction message definition of the transaction message to be analyzed is acquired, the transaction message to be analyzed can also be completed.
