API verification and API document generation method and system based on API gateway

The invention discloses an API (Application Program Interface) verification and API document generation method and system based on an API gateway, belongs to the technical field of computer network API gateways, and aims to solve the technical problem of how to verify an API identifier and write an API document and relieve the learning burden of developers. Performing API normative verification on the access gateway API based on the standard of opening the API; an API (Application Program Interface) resource document based on a swagger specification is automatically generated for an expression state transition application programming interface of the access gateway; for the upstream service of each access gateway, automatically analyzing the entered API through a verification tool of the Restful API, and then using a related method to search whether the standard is met or not; and after checking, inputting related information into the user API. 本发明公开了一种基于API网关的API验证和API文档生成方法及系统，属于计算机网络API网关技术领域，本发明要解决的技术问题为如
