假设已经有一个ws服务端在运行，提供由用户id查询用户名的服务，下面直接使用其soap服务定义 .h 文件在qt中开发客户端。



1. 准备
1.1 create directory:
soaptest/client/
soaptest/gsoap/

1.2 DOWNLOAD gsoap_2.8.15.zip, extract following file/directory to soaptest/gsoap/:
gsoap_2.8.15.zip\gsoap-2.8\gsoap\bin_win32\
gsoap_2.8.15.zip\gsoap-2.8\{stdsoap2.h, stdsoap2.cpp}
gsoap_2.8.15.zip\gsoap-2.8\import\

2. soapcpp2 编译
2.1 edit soap H file:
soaptest\gsoap\test.h
====================================================
//gsoap ns service name: cu
//gsoap ns service namespace: http://localhost/cu.wsdl
//gsoap ns service location: http://localhost/home/cu
//gsoap ns service executable: cu.cgi
//gsoap ns service encoding: encoded
//gsoap ns schema namespace: urn:cu
//gsoap ns   schema form: unqualified


struct ns__MyTestRequest
{
    char* id;
};

struct ns__MyTestResponse
{
    int Result;
    char* name;
};

int ns__MyTest(struct ns__MyTestRequest *req, struct ns__MyTestResponse *rsp);
====================================================

2.2 soapcpp2
E:\Qt\QtGuiEx\soaptest\gsoap> bin_win32\soapcpp2 -j -I"./import" test.h

Note:
-C generate webservice client
-c pure c
-j with proxy

3. 编译客户端
根据上一步 soapcpp2 是否带选项 -j，打开/关闭下面的宏定义，然后编译qt程序。
//#define USING_PROXY -j

4. 运行结果
输入 id="pz"
输出 name = "pengzhen"
