Application program interface simulation debugging method based on open bank platform

The invention discloses an application program interface simulation debugging method based on an open bank platform. The method comprises the following steps: acquiring test script data; according to the test script data, performing feature extraction on the script, and screening the extracted features in a test module database to generate a screening result; according to the screening result, a first test template module is constructed, and the test template module comprises a conventional test module, an abnormal test module and an overload test module; performing data distribution on the test script data through a gateway to generate a test result; whether the system is normal or not is judged according to the test result, if the system is abnormal, a second test template module is constructed for debugging again, and a test module for simulating a test application program interface is established, so that in the test process of an innovative function, the construction of a test architecture is rapidly com
