The embodiment of the invention provides a service data interaction method, device and system. The method comprises: receiving interface configuration information sent by any service page module; On the basis of the interface configuration information, configuring an HTTP request, and sending the HTTP request to a server, so that the server can return response data on the basis of the HTTP request; And receiving response data, and sending the response data to the business page module. According to the method, device and system, for Data interaction between a single service and a server, configuration information of an interface is packaged, an HTTP request is configured based on the interface configuration information; The code sharing of HTTP request configuration for the interface configuration information under different services is realized, redundant codes are reduced, the development efficiency is improved, the later maintenance cost is reduced, the coupling between different service page modules in the data interaction process is reduced, and the maintainability of a project is improved.
