However, the interface data format of the payment platform corresponding to each bank has great difference, and the main attributes of the difference include: 1) message formats such as KV, XML, JSON,8583, etc.; 2) outgoing means such as HTTP, SOCKET, etc.; 3) signature means such as Ansi99, XMLSignature, RSA certificate, etc.
But when corresponding to the payment platform interface, the flow of each bank interface is basically consistent, and the main interface flow comprises the following steps: receiving messages, converting parameters (converting parameters in the payment platform into parameters required by the bank), assembling message plaintext (without signature data), signing, assembling outgoing messages (with signature data), outgoing/receiving (through http or socket), analyzing messages, assembling message plaintext (with data required to be checked), checking, converting data (converting parameters in the bank into parameters in the payment platform), and returning data.
When the payment platform and the banks carry out request interaction, the interface performance of each bank is greatly different, the response time is different, and the supported maximum concurrency number and the supported maintenance time are different. If all banks share the same service resource, when a certain bank has a performance bottleneck, the use of other bank channels on the same server is affected slowly, and even an avalanche phenomenon is caused.

And after the bank gateway interface passes the substituted execution result, returning the running data of the execution result substituted by the bank gateway interface. And after the data connection instruction is successfully analyzed through the operation result, the target terminal sending the data connection instruction is successfully connected with the bank gateway interface. And the execution result is in the form of a parameter conversion format, and the information of the parameter conversion format is substituted into the bank gateway result to analyze the content of the data connection instruction. And the operation data returned to the bank gateway interface is data information returned by operating the current access step of the bank gateway interface based on the execution result after the bank gateway interface substitutes the execution result. And monitoring the analysis process of analyzing the target connection instruction by the bank gateway interface through a preset monitoring mechanism.

The monitoring mode is that the execution state of the handler is confirmed according to the execution log file or the execution thread state of the handler. If a problem occurs in the execution log file or the execution thread state and the problem is confirmed to be a preset execution problem which is confirmed to influence an execution result, recording the preset execution problem into a corresponding log file according to the current occurrence of the preset execution problem and the handler, and then calling a file text of the preset configuration file corresponding to the handler according to the preset execution problem.
Step S60, according to the execution problem, correspondingly modifying the content of the configuration file;
editing the corresponding content in the text of the preset configuration file according to the preset execution problem, for example, the current execution problem is that an outgoing/received message is wrong, modifying the receiving format of the outgoing/received message in the preset configuration file in the text of the preset configuration file, and storing the modified outgoing/received message after the modification is completed. The preset execution problem is a monitored execution problem, the occurrence mode of the execution problem is confirmed by a monitor or a monitor program, and the text operation of modifying the preset configuration file also modifies the text content of the preset configuration file for the monitor or a corresponding developer. And after the preset configuration file is modified, the preset configuration file is still stored in a preset storage area of the preset configuration file.
And step S70, storing the modified configuration file, triggering a preset calling mechanism, then sending the modified configuration file to a corresponding server, and reconfiguring the handler responsibility chain by adopting the modified configuration file and executing the reconfigured handler responsibility chain.

In this embodiment, the content of the preset configuration file is reinitialized by monitoring the execution process of the preset configuration file and modifying the content of the corresponding preset configuration file according to the execution error, so that the situation that the access to the bank gateway interface is influenced because a correct execution result cannot be obtained after the preset configuration file is in error in the execution process is prevented. And the preset configuration file is initialized by modifying the configuration file, issuing, loading and calling, so that the connection efficiency of the bank gateway interface is improved.
