The invention provides a uniform interface management method and system. The method comprises the following steps that: obtaining the protocol information of each service interface in an interface warehouse, wherein the protocol information comprises an interface type, an incoming parameter, an outgoing parameter, a routing rule, calling overtime time and a data mapping rule; according to a business request which is sent to an HTTP (Hyper Text Transfer Protocol) interface by a user, obtaining a routing rule in the protocol information of the HTTP interface, and determining a service interfacecalled by the HTTP interface according to the routing rule; according to the protocol information, obtaining the interface type of the called service interface, and calling the service interface according to the incoming parameter and the outgoing parameter of the interface type; and obtaining business data returned from the called service interface, and sending the business data to the user according to a data mapping rule. By use of the method, different service interfaces can be uniformly managed and monitored, in addition, various routing rules are used for effectively lowering the development and maintenance cost of functions including tangential flow, gated lunch and the like.
