Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
It should be noted that the packet unpacking method provided by the present invention can be used in the communication field or the financial field. The above is only an example, and does not limit the application field of the packet unpacking method provided by the present invention.
The message unpacking refers to converting a message in one format into a message in another format. For example, a message ISO8583 (8583 packet for short) conforming to an international standard format established by a bank card electronic transaction system is converted into a general lightweight JSON (JavaScript Object notification) message in a lightweight data exchange format, so that the message can be separated from the bank card electronic transaction system, and the bank card electronic transaction system has wider universality.
When the ISO8583 message is converted into the JSON message, the JSON message needs to correspond to downstream systems one by one, so that different conversion algorithms need to be formulated to convert the ISO8583 message into the JSON message, and workload is complex.
In view of this, the present application provides a packet unpacking method. The method is applied to the electronic equipment. The electronic device is a device having a data processing capability, and may be, for example, a server, or a terminal device such as a desktop computer, a notebook computer, or a smart phone.
Specifically, the electronic device obtains a first message including target data, then analyzes the first message according to a parameter configuration table, obtains a target parameter configuration table including the target data, and then generates a second message having a format different from that of the first message according to the target parameter configuration table including the target data. Therefore, the target data in the first message is read by establishing the target parameter configuration table, and then the target data is converted into the second message from the target parameter table, so that the unpacking of the message is realized, and the conversion of the message format is realized.
In order to facilitate understanding of the technical solution of the present application, the following describes a packet unpacking method provided by the present application with reference to fig. 1.
Referring to the flowchart of the packet unpacking method shown in fig. 1, the method specifically includes the following steps:
s102: the electronic equipment acquires the first message.
The first message is a message in a first format including data. The message in the first format may be directly acquired by the electronic device, and the message in the first format needs to be converted into the message in the second format, so as to realize unpacking of the first message. The first message may be a message conforming to an international standard format established by a bank card electronic transaction system, that is, an ISO8583 message.
An ISO8583 message (8583 packet for short) is an international standard packet format, and includes a header and a body. In application, the upstream and downstream systems unpack the packet according to mutually agreed specifications. Further, the 8583 packet also relates to the content of many fields, possibly with a sub-tag (tag) in each field.
S104: and the electronic equipment analyzes the first message according to the parameter configuration table to obtain a target parameter configuration table comprising target data.
The parameter configuration table may be established in advance, and in response to the setting of the developer, the electronic device establishes the parameter configuration table. Specifically, which fields can support the conversion between the ISO8583 message and the JSON message is analyzed. Wherein the parameter configuration table includes configuration data corresponding to the target data. The parameter configuration table may be as shown in fig. 2.
The parameter configuration table may include a domain number, a packet format number, an internal transaction code, a domain name, a domain type, a maximum domain definition length, domain content data, a domain length attribute, a transcoding flag, and a domain remark. The electronic device may obtain the target data in the parameter configuration table from the first message, for example, whether the data is included, and the specific reason why the data is included.
Wherein the message format number and the internal transaction code co-locate a unique transaction. Other fields are for example: the domain number, domain name, domain type, and domain definition length, etc. together determine the parsing rule of an ISO8583 domain and what the key to convert directly to a JSON domain is. The method can accurately configure the analysis rule of the 8583 packet, and is flexibly suitable for specifications of various upstream and downstream systems.
Fig. 3 is a schematic diagram of a partial configuration of a consumption transaction, in which JLDIDX corresponds to the field number of ISO 8583. For example, the second configuration represents a transaction having a message format number of CSCP and a transaction code of 0200000000. The electronic equipment acquires an ISO8583 message, and analyzes a 2 nd field according to a variable-length character string, wherein the first two bits represent the length, and the maximum length of the field is 19 bits.
After the parameter configuration table is established, the method further comprises: and the electronic equipment carries out validity check on the configuration data.
Wherein the validity check includes checking at least one of a transaction code type, a domain name, a domain length, a domain transcoding, and a domain content type in the configuration data.
The validity check of the configuration data is similar to a grammar checker, and the validity and the correctness of the configuration are ensured by checking the transaction code type, the domain name, the domain length, the domain transcoding, the domain content type and the like, so that invalid configuration is avoided, and the problem of packet loss caused by the fact that the configuration problem is discovered only when the message is received and analyzed is avoided.
After the parameter configuration table is established, the method further comprises: and loading the configuration data in the parameter configuration table into a memory. The configuration data in the parameter configuration table is pre-loaded to the memory in advance, so that the program can be quickly read when being started without frequent interaction with the database.
Therefore, the electronic device may obtain the first message as follows: and the electronic equipment acquires the first message in the memory.
As shown in fig. 4, specifically, the electronic device may include a preprocessing module, a validity checking module, and a message interpreting module, where the preprocessing module is configured to pre-establish a parameter configuration table and load the parameter configuration table into a memory, the validity checking is used to check validity and correctness of the parameter configuration table, and the message parsing module is configured to identify a first message and convert contents in the parameter configuration table into a second message.
In S104, the method may specifically include: the electronic equipment acquires the label, the label domain, the key mapping relation and the domain analysis rule in the parameter configuration table; and analyzing the first message according to the label (tag), the label domain, the key mapping relation and the analysis rule of the domain to obtain a target parameter configuration table comprising target data.
S106: and the electronic equipment generates a second message according to the target parameter configuration table.
The second message is in a format different from that of the first message. For example, when the first packet is an ISO8583 packet, the second packet may be a JSON packet. The JSON message is a lightweight data exchange format. The text format completely independent of languages is adopted, and the text format consists of an object (collection), an array and a key/value element, and can be mutually nested. The ISO8583 message is a message mainly applied to upstream and downstream systems of a bank, the JSON message is a message with high universality, and the universality of the message can be improved by converting the ISO8583 message into the JSON message.
And reading the configuration data of the configuration table so as to support the conversion of the ISO8583 message and JSON message domains of the transaction data.
In some possible implementations, when the content in the first message needs to be modified, the method may further include: and the electronic equipment modifies the target parameter configuration table according to the modification requirement.
In the related art, when the service requirement changes and the content in the first message needs to be modified, the related conversion algorithm needs to be re-formulated for modification, for example, a transaction calling the function is re-hard-coded, and test verification is performed. In the scheme, when the content in the first message needs to be changed, only the parameter configuration table needs to be modified, then the first message can be analyzed through the modified parameter configuration table to obtain the target data, and then the second message is generated according to the modified target parameter configuration table, so that the first message is modified.
In the scheme, the target data in the ISO8583 message is converted into the parameter configuration table, and then the parameter configuration table is directly converted into the JSON message, so that the conversion can be realized by adopting a program hard code without analyzing a specific code, the protocol specification between upstream and downstream systems of the ISO8583 message is not depended on, only the target data in the ISO8583 message needs to be written into the parameter configuration table, and then the target data in the parameter configuration table is converted into the JSON message. The conversion method based on the parameter configuration table has flexible configuration and convenient version deployment.
As shown in fig. 5, the electronic device corresponding to the system in this embodiment preprocesses the parameter, performs validity check on the parameter after the parameter preprocessing is successful, can parse the ISO8583 message after the validity check is successful, and obtains the JSON message when the message is parsed successfully, thereby implementing format conversion from the ISO8583 message to the JSON message. And if any one of the parameter preprocessing, the validity check and the message analysis fails, the message is not continuously processed.
Based on the description of the above content, an embodiment of the present application provides a packet unpacking method, where the method obtains a first packet including target data, then parses the first packet according to a parameter configuration table, obtains a target parameter configuration table including the target data, and then generates a second packet having a format different from that of the first packet according to the target parameter configuration table including the target data. Therefore, the target data in the first message is read by establishing the target parameter configuration table, and then the target data is converted into the second message from the target parameter table, so that the unpacking of the message is realized.
