soap实例 客户端(c++) + 服务器端(web + com+)-客户端调用

远程soap服务器端有个com其中一接口是

HRESULT GetTemp([in]BSTR Url,[out,retval]BSTR*Return);

他的实现是

STDMETHODIMP CGetTime::GetTemp(BSTR Url, BSTR *Return)

{

// TODO: Add your implementation code here

*Return = SysAllocString(_T("jones"));

return S_OK;

}

现在在客户端用soap调

#import "c:\Program Files\Common Files\MSSoap\Binaries\mssoap30.dll" raw_interfaces_only, exclude("IStream", "ISequentialStream", "_LARGE_INTEGER", "_ULARGE_INTEGER", "tagSTATSTG", "_FILETIME", "IErrorInfo")

using namespace MSSOAPLib30; //soap的dll

int main(int argc, char* argv[])

{

CoInitialize(NULL);

_variant_t result;

DISPID dispidFn=0;

HRESULT hr;

ISoapClientPtr pSoapClient;

pSoapClient=ISoapClientPtr(__uuidof(SoapClient30));

long lValue=10;

try

{

//连接soap站点

hr=pSoapClient->MSSoapInit(_bstr_t("http://192.168.100.171:8888/SoapTest.WSDL"),

_bstr_t("SoapTest"),_bstr_t("GetTimeSoapPort"),NULL);

if(FAILED(hr))

{

printf("MSSoapInit 失败\r\n");

_com_issue_error(hr);

}

LPOLESTR pServiceName = L"GetTemp"; //得到Com中的GetTemp的方法ID

hr = pSoapClient->GetIDsOfNames(IID_NULL, &pServiceName, 1,

LOCALE_SYSTEM_DEFAULT, &dispidFn);

if(FAILED(hr))

{

printf("GetIDsOfNames 失败\r\n");

}

else

{

TCHAR strData[126]={0};

VARIANT args[1]={0};

args[0].vt = VT_BSTR;

wsprintf(strData,"test");

args[0].bstrVal = _bstr_t(strData).copy(); //传的参数 既BSTR Url ,如果有多个参数 那args[]就是传的参数的数组

EXCEPINFO excepinfo={0};

DISPPARAMS params={0};

params.cArgs = 1;

params.rgvarg= args;

_variant_t result; //返回的是BSTR *Return 即"jones"

UINT uArgErr=0;

//调用GetTemp的方法

hr=pSoapClient->Invoke(dispidFn, IID_NULL, LOCALE_SYSTEM_DEFAULT,

DISPATCH_METHOD, &params, &result, &excepinfo, NULL);

if(FAILED(hr))

{

printf("Invoke 失败\r\n");

_com_issue_error(hr);

}

else

{

params.rgvarg[0].plVal;

}

}

}

catch(_com_error& e)

{

TCHAR str[205]={0};

wsprintf(str,"%s,%s,%s,%d",e.Source(),e.Description(),

e.ErrorMessage(),e.Error());

}

CoUninitialize();

return 0;

}

好了一个简单的soap调用就完成了.
