Abstract
The invention discloses a communication system and particularly relates to a remote-procedure calling method, which comprises the following steps of: analyzing the parameter of a remote procedure by using an analyzing script, and generating a corresponding input-parameter structural body, a corresponding return-information structural body and a corresponding remote-procedure ID (Identity) according to parameter information; and according to the definition of the remote procedure, generating the calling function of a remote-procedure client terminal through the analyzing script, and the like. According to invention, message packing and message unpacking in the calling process of the remote procedure can be simply realized through the analyzing script, and developers only need to pay close attention to the realization of remote-procedure functions without paying attention to complicated communication flows among the procedures, so that the workload of coding is reduced in the development of projects, and the development efficiency is improved.
Description
Technical field
The present invention relates to a kind of communication system, particularly relate to a kind of remote procedure calling (PRC) method.
Background technology
In software systems, along with the increase day by day of functional requirement, the module that realizes of system also gets more and more, and the interactive communication between module (process) also comes more.In most cases, the implementation of the communication of intermodule is all, define a structure and a message numbering, then will the Information encapsulation of communication be needed to send again in this structure, server end also needs to write corresponding code process Decoding Analysis and realizes communication, the intricate operation of this part is complicated and easily make mistakes, and developer needs the cost plenty of time to write code and debugging code, and is absorbed in the functional development after message communicating.
Summary of the invention
The object of the present invention is to provide a kind of remote procedure calling (PRC) method, solve intermodule communication mode scaling complexity and the problem of easily makeing mistakes.
For solving the problem, the technical solution used in the present invention is:
A kind of remote procedure calling (PRC) method, comprises the following steps:
Use the parameter analyzing script remote process, generate corresponding input parameter structure, return information structure and remote process ID according to parameter information;
According to the definition of remote process, analyze the call function that script generates remote process client;
According to the definition of remote process, analyze the call function that script generates remote process server end;
According to the definition of remote process, analyze the remote process ID of script generation server end and the call function mapping table of script generation remote process server end;
Analyze the setup code that script generates remote process server end, monitor and receive the message that client sends, take out the remote process ID carried in message, corresponding function is obtained according to remote process ID and call function mapping table, the input parameter structure carried in message is called and obtains corresponding function according to remote process ID and call function mapping table as function parameter and obtain Output rusults, Output rusults is sent it back client process;
After remote server process initiation, call and analyze the setup code that script generates remote process server end;
When client process needs to call remote process, call and analyze the call function that script generates remote process client.
Further technical scheme is the definition according to remote process, and analyze the call function that script generates remote process client, the method for code is as follows:
The input parameter content of function is copied to one by one the memory headroom of input parameter structure application;
Then this partial content is added that remote process ID is sent to remote process;
Wait for that remote process returns response;
After receiving long-range response, result is copied in return value;
Function returns.
Further technical scheme is the definition according to remote process, and analyze the call function that script generates remote process server end, the method for code is as follows:
The message content receiving client is resolved according to input parameter structure and copies in function parameter variable;
Call remote process function;
By return results copy to return information structure memory headroom in;
Function returns.
The beneficial effect that produces of technique scheme is adopted to be: can simply by analyzing script to realize message encapsulation in remote procedure call process and message unpacks, developer only need to pay close attention to remote process function realization and without the need to being concerned about communication process loaded down with trivial details between process, in the exploitation of project, reduce the workload that code is write, improve development efficiency.
