Gsoap

The gSOAP toolkit simplifies the development and deployment of SOAP/XML Web Services and client applications in C and C++. The gSOAP RPC compiler does all the difficult work for you. It generates the necessary C and C++ source codes to seamlessly glue your C/C++ applications to the SOAP/XML Web Services stack. With the compiler you can enable your (existing) C and/or C++ applications to “talk SOAP”!.



gSOAP is not just a class library. The gSOAP RPC compiler produces routines to encode native and user-defined C/C++ types in XML. To make things even easier, gSOAP provides memory management with garbage collection so (XML-decoded) data can be cleaned up without a hassle.

Calling WCF Services from a Linux C++ Client Using gSOAP

Step 1: Build a server Web service by WCF

First, you need to make a server webservice by c#. Please follow this tutorial http://www.youtube.com/watch?v=GzN1vHWlJjA

When you finished to created a server. We will get link: http://www.myserver.com/myWCFservice.svc

Step 2: Download the gSOAP tar file. The website is here.

Step 3: Generate the WSDL header file.

wsdl2h -o mywcfheader.h http://myserver.com/myWCFService.svc?wsdl

1	wsdl2h -o mywcfheader.h http://myserver.com/myWCFService.svc?wsdl

Step 4: Generate the stub files by executing the gSOAP compiler

soapcpp2 -I “/lib/gSOAP/gsoap-2.7/gsoap/” mywcfheader.h

Step 5: Create the client

#include “BasicHttpBinding_IMyService.nsmap” using namespace std; int main() { // This will be the name of the service // class in the proxy header file from above BasicHttpBinding_IMyService s; // This is the request and response that // the service you are trying to call takes. // Again you can find the types in the class // used in the C++ proxy header _ns1__GetCount req; _ns1__GetCountResponse resp; string is(”Hello There America”); req.inputString = &is; int err = s.__ns1__GetCount(&req, &resp); if (SOAP_OK == err) cout << “Service Returned: ” << *resp.GetCountResult << endl; else cout << “Error: ” << err << endl; return 0; }

#include “BasicHttpBinding_IMyService.nsmap”   using namespace std;   int main()   {     // This will be the name of the service     // class in the proxy header file from above     BasicHttpBinding_IMyService s;       // This is the request and response that     // the service you are trying to call takes.     // Again you can find the types in the class     // used in the C++ proxy header     _ns1__GetCount req;     _ns1__GetCountResponse resp;       string is(”Hello There America”);     req.inputString = &is;       int err = s.__ns1__GetCount(&req, &resp);       if (SOAP_OK == err)         cout << “Service Returned: ” << *resp.GetCountResult << endl;     else         cout << “Error: ” << err << endl;       return 0; }

Step 6: Compile the client

g++ -I "/lib/gSOAP/gsoap-2.7/gsoap" myclient.cpp soapC.cpp soapClient.cpp /lib/gSOAP/gsoap-2.7/gsoap/stdsoap2.cpp

1	g++ -I "/lib/gSOAP/gsoap-2.7/gsoap" myclient.cpp soapC.cpp soapClient.cpp /lib/gSOAP/gsoap-2.7/gsoap/stdsoap2.cpp
