C + + Call WebService

1. gSOAP is an open source project that makes it easy to do SOAP client and server-side programming with C + +, without having to understand the details of XML and SOAP protocols

Wsdl2h.exe: Compiling a WSDL file to generate A/C + + header file

-o file name, specifying output header file
The-n namespace prefix replaces the default NS
-C generates a pure code, otherwise C + + code
-S do not use STL code
-t file name, specifying type map file, default = Typemap.dat
-e prohibit namespace prefixes for enum members

Soapcpp2.exe:gSOAP compiler, the compiler header file generation server and the client-side both the C + + files required (using STL by default, requires Stlvector.h)

-C generates only client code
-S generates server-side code only
-L do not generate SOAPCLIENTLIB.C and SOAPSERVERLIB.C files
-C generates a pure code, otherwise C + + code (related to header file)
-I specify the import path (see above)
-X do not produce an XML sample file
-I generates C + + wrapper, client is XxxxProxy.h (. cpp), server side is xxxxService.h (. cpp)

2. Generating the Memory client stub program and framework
Wsdl2h-o xx.h http://192.168.40.8:88/GMM?wsdl

or Wsdl2h-o xx.h http://js.gps163.com:8994/Server/CsService.svc?wsdl
Soapcpp2-c-l-x-I xx.h (soapcpp2 xx.h-c-i D:\gsoap-2.7\gsoap\import)

3. Add the following generated files to the project:
Soapstub.h,soaph.h,stdsoap2.h

Soapc.cpp,soapclient.cpp,stdsoap2.cpp

Soapbasichttpbinding_uscoreigmmproxy.cpp

Soapbasichttpbinding_uscoreigmmproxy.cpp

Basichttpbinding_uscoreigmm.nsmap

Wsock32.lib

4. Call

#include "Soapbasichttpbinding_uscoreigmmproxy.h"
#include "Basichttpbinding_uscoreigmm.nsmap"

Proxy mode call does not require initialization
struct SOAP Xxsoap;
Soap_init (&XXSOAP);

Proxy class object
Xxwebservicesoap Xxproxy;

Set Header information
Soap_env__header Envheader;
Xxproxy.soap->header = &envHeader;

Web Service object
_ns1__xx xx;

Web Service Result Object
_ns1__xxresponse Xxresponse;
