The embodiment of the invention provides a data generation method and device, and belongs to the technical field of computer communication. The method includes the following steps that when a user needs calling in the remote procedure, an IDL file formed according to the preset default syntax of the remote asynchronous communication interface is obtained, wherein the preset default syntax of the remote asynchronous communication interface includes a data structure, a data type and a communication interface which define the remote asynchronous communication interface, and the parameter of the communication interface; according to the preset default syntax of the remote asynchronous communication interface, the IDL file is analyzed, a client-side calling agent code, a server -side calling agent code and a server side corresponding to the IDL file are generated to achieve class definition. Therefore, Through the IDL file formed by the user through the preset default syntax of the remote asynchronous communication interface, remote procedure call can be achieved, various matched protocols, matched codes and the like are not needed in the development process, the difficulty of development is greatly reduced, and the practicability and applicability of remote procedure call in the implementation process are thus effectively improved.
