judging whether the request is an authentication request of a login user, if so, directly analyzing a request URL, forwarding the request to the service module for authentication, if the request passes the authentication, generating a token, storing the token in a system cache, adding the token to a response head, returning, and if the request does not pass the authentication, returning to 401 to prohibit access errors;
if the API interface gateway judges that the request is not a login user authentication request, the token carried by the request head is authenticated, if the authentication is not passed, an unauthorized error is returned 403, if the authentication is passed, the URL address of the request is analyzed, the API interface gateway searches the IP address and the port number of the corresponding service in the service management center, if the corresponding service information is found, the found IP address and the found port number are used, the request is forwarded to the service corresponding to the service module for processing, and if the corresponding service information is not found, the file is returned 404, and the error cannot be found.
