Method, device and system for using and invoking Oauth API

A method for invoking an Oauth API, which is performed by an application running engine, comprising:

• intercepting, by the application running engine, an application request message from a client,
• allocating, by the application running engine, a customer serial number according to a current session identifier, and storing, by the application running engine, the customer serial number;
• receiving, by the application running engine, an Oauth API invoking request carrying the customer serial number, wherein the Oauth API invoking request is sent by the client through invoking a client requesting Oauth API interface;
• authenticating, by the application running engine, the Oauth API invoking request according to the customer serial number;
• obtaining, by the application running engine, interface binding information corresponding to an Oauth API which is requested to be invoked after the authentication is passed;
• performing, by the application running engine, authorization and authentication according to the interface binding information, and obtaining, by the application running engine, an access token form an Oauth provider;
• injecting, by the application running engine, the access token into the Oauth API invoking request, and sending, by the application running engine, the injected Oauth API invoking request to the Oauth provider, so that the Oauth provider responds to the injected Oauth API invoking request, and returns Oauth API returned information;
• and
• returning, by the application running engine, the Oauth API returned information to the client, so as to complete the Oauth API invoking;
• wherein the performing the authorization and authentication according to the interface binding information comprises:
• obtaining an authorization and authentication interface from the interface binding information, and running the authorization and authentication interface to complete authorization and authentication;
• or obtaining interface mapping information corresponding to an interface in Oauth SDK from the interface binding information, invoking a specific interface in the Oauth SDK via a mapped interface name and a mapped parameter name to complete authentication and authorization.
