 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"

 //#define USING_PROXY -j
 const char *endpoint= "http://192.168.250.101:9000/cu";

 #ifdef USING_PROXY

 // with proxy
 #include "../gsoap/soapcuProxy.h"
 int main(int argc, char*argv[])
 {
     cuProxy soapX;

     struct ns__MyTestRequest req = {"pz"};
     struct ns__MyTestResponse res;



   soapX.MyTest(endpoint, NULL, &req, &res);
   qDebug()<< "result:" << res.Result;
   if(res.Result == 0)
   {
       qDebug() << "name of " << req.id << ":" << res.name;
   }

 return 0;
 }

 #else

 // without proxy
 #include "../gsoap/soapH.h"

 int main(int argc, char*argv[])
 {
     struct soap soapX;
     soap_init(&soapX);
     //soap_set_namespaces(&soapX, cu_namespaces);
     soap_set_mode(&soapX, SOAP_C_UTFSTRING);

     struct ns__MyTestRequest req = {"pz"};
     struct ns__MyTestResponse res;

   soap_call_ns__MyTest(&soapX, endpoint, NULL, &req, &res);
   qDebug()<< "result:" << res.Result;
   if(res.Result == 0)
   {
     qDebug() << "name of " << req.id << ":" << res.name;
   }



 return 0;
 }
