Method and system for interaction between server and client

Abstract

The invention provides a method and system for interaction. In the method, a client agent receives call information and a parameter set; a client serializer serializes the parameter set into data in a standard data type format and sends the serialized parameter set and the call information to a WCF (Windows Communication Foundation) client; the WCF client sends the parameter set and the call information to a WCF server; when receiving the parameter set and the call information, the server agent acquires a parameter type list of a business method, calls a server serializer to deserialize the serialized parameter set into a parameter set, calls a business method by using a reflection technology, transfers the parameter set to the business method, acquires the return value of an execution business method and sends the return value to the WCF server; the WCF server sends the return value to the WCF client; the WCF client sends the return value to the client agent; and finally, the return value is sent to the client. By the adoption of the method and system provided by the invention, the WCF service is separated from a data class and a business class.

Description

technical field [0001] The present invention relates to an interaction technology based on WCF service, in particular to an interaction method and an interaction system between a server and a client. Background technique [0002] Silverlight has gradually become one of the mainstream technologies for developing clients. As the basis for the interaction between Silverlight clients and .net servers, WCF (Windows Communication Foundation) services are more and more widely used. [0003] figure 1 A schematic diagram of a WCF service is shown. like figure 1 As shown, in order to realize the interaction between the Silverlight client and the .net server through the WCF service, it is necessary to create a WCF server and a WCF client. [0004] For easy understanding, the interaction between the client and the server can be compared to making a phone call. At this time, the WCF service is equivalent to a telephone line, the WCF server and WCF client are equivalent to two phones, ...

AI Technical Summary

Problems solved by technology

[0009] 1. WCF services can only call business classes declared as service contracts. That is to say, if a Silverlight client wants to access a method of a business class on the .net server, it must declare the business class as a service contract and write In the code of WCF server and WCF client

[0010] 2. WCF services can only pass standard data types (such as integers, strings, etc.) or data classes declared as data contracts, that is to say: if you want to pass a certain data class through WCF services, you must declare the data class It is a data contract and written into the code of WCF server and client

When the business class and data class to be accessed / passed are outside this range, the WCF server and WCF client must be modified to add the corresponding service contract and data contract, resulting in poor scalability of the system
