The present solution applies to the field of network technology and provides a service response method and middleware thereof. The method comprises: receiving registration information sent by a user; adding, according to an identifier and log-in information, an additional service to a corresponding responsive service list for the user on a third party service platform, wherein the additional service is a service in addition to those on the responsive service list; receiving a service request sent by the user, and determining whether the service type corresponding to the service request is the additional service; and if so, responding to the service request via middleware. According to the present invention, a user can register with middleware, obtain an additional service permission for a third party platform, and issue a respective additional service request using the third party service platform. The third party service platform receives the additional service request, and then assigns the same to the middleware to respond to. In this way, the present invention provides more services to a user, and solves problems of current third party service platforms such as failure to satisfy a large number of service requests from a user and poor user experience.
