Application program interface generation method and related equipment

The embodiment of the invention provides an application program interface (API) generation method and related equipment. The method comprises the following steps: receiving API element information input by a user and a downstream service interface corresponding to the API and selected by the user; pulling a request parameter of the downstream service interface and a response parameter of the downstream service interface according to the downstream service interface; generating at least one API request parameter corresponding to the request parameter of the downstream service interface and at least one API response parameter corresponding to the response parameter of the downstream service interface; generating a rule engine corresponding to the API; and storing the rule engine corresponding to the API to the address of the API. According to the API generation method and the related equipment, the API can be rapidly generated, the communication cost of API development is greatly reduced, the development effici
