The SVC6 console program uses SoapToolkit3.0 to invoke WebService

1. First install the SOAPTOOLKIT3.0 installation package and install it (my installation directory is: C:\Program files\common Files)

2. New VC Console Program (empty project), project name: Winconsole6invokewebservice, adding a C + + source file (main.cpp)

3. Main.cpp Source Code

#include <stdio.h> #include <iostream> #include <vector>  #import "Msxml4.dll"  using Namespace std;using namespace msxml2;  #import "C:\Program Files\Common Files\mssoap\binaries\mssoap30.dll"         exclude ("IStream", "IErrorInfo", "ISequentialStream", "_LARGE_ INTEGER ",         " _ularge_integer "," Tagstatstg "," _filetime ")   Using namespace mssoaplib30; void query (char* endpointurl, char* namespace, char* method, vector<string> & V) {    isoapserializerptr serializer;    isoapreaderptr Reader;     isoapconnectorptr connector;         // Connect to the Service    connector.createinstance (__uuidof (HTTPCONNECTOR30));     connector->property["Endpointurl"] = endpointurl;       //Interface location &nBsp;   connector->connect ();                                     //and server connection          // Begin message    connector->property["soapaction"] = _bstr_t (Namespace) + _bstr_t (method);     connector->beginmessage ();      serializer.createinstance (_ _uuidof (SOAPSERIALIZER30))      //Connect serializer to connector input string      serializer->init (_variant_t ((iunknown*) connector->inputstream));      // Create a SOAP message     serializer->startenvelope ("Soap", "", "");     serializer- >startbody ("body");     serializer->startelement (method, Namespace, "", ""); namespaces must have &NBSP;&NBSP;&NBsp;  for (Vector<string>::iterator it = V.begin (); It! = V.end (); it++)     {         serializer->startelement ("username", Namespace, "", "");         serializer->writestring (It->c_str ());         serializer->endelement ();    }      Serializer->endelement ();      serializer->endbody ();     Serializer->endenvelope ();      connector->endmessage ();             //Send the message to the Web service     / /Read Response     reader.createinstance (__uuidof (SOAPREADER30));    reader-> Load (_variant_t (iunknown*) connector->outputstream), "")      printf ("Answer:%s\n",(const char*) Reader->rpcresult->text); Reader->rpcresult->gettext () equivalent} int main (int argc, char* argv[]) {    coinitialize (NULL);     char* endpointurl = "Http://192.168.0.100/WebService1/Service.asmx";     char* Namespace = "http://tempuri.org/";     vector<string> v1, v2;      v2.push_back ("Joeblack");     query (EndPointURL, Namespace, " Hello ", v2);      couninitialize ();     getchar ();      return 0;}

　　

3> Publish the service through VS2010, add webservices, file name Service.asmx, cannot be published through WCF, otherwise the above code returns wrong.

Service.asmx File Source
