The invention discloses a method and a device for mixing and matching services, wherein the method comprises the following steps of: providing an injection interface for the services; injecting the services through the injection interface; adding the injected services to a list according to scheduled rules; generating a visualization component of the services in the list; and mixing and matching the services by dragging the visualization component. According to the method of the invention, on the one hand, the visualization component is generated by injecting services through the injection interface, and a development environment for mixing and matching visualization services is provided for users to realize visualization of service mixing and matching, and on the other hand, services are packaged in a manner of a component, and mixing and matching of the services can be carried out through dragging the service component directly by users to a workspace during using, so that the difficulty of mixing and matching the services is reduced significantly, procedures such as service parsing, invoking, data transferring, and the like in mixing and matching of the services are shielded at the same time, and development of users is greatly facilitated.
