WEB-based background server access method and system

The invention discloses a WEB-based background server access method and system. The method includes: a semantic object building module of WEB front end builds semantic objects according to WEB front end script langue object model feature and semantic codes input by a user; a semantic extraction module of the WEB front end extracts corresponding to-be-accessed module name information, member method name information of a to-be-accessed module and interaction parameter information from the obtained semantic objects and transmits the three to a background server; a matching and calling module of the background server calls the corresponding to-be-accessed module according to the to-be-accessed module name information, the member method name information of the to-be-accessed module and the interaction parameter information and return the calling result to the WEB front end; an execution module of the WEB front end processes the calling result according to callback function information of the WEB front end. By the method, the problems that program deployment is complex, poor in stability and high in risk are solved.
