调用代码如下
int CallWeb(string UserName)
{
USES_CONVERSION;
int temp=0;
CComPtr <IXMLHTTPRequest> spXMLHTTP;
HRESULT hr = spXMLHTTP.CoCreateInstance(CLSID_XMLHTTP40);
CHECK_HR(hr);
//string Act=Act.append(checkAttendanceCardNum).append(" ").append(checkTime);
TCHAR szSOAPReq[MAX_PATH*2] = {0};
sprintf(szSOAPReq, g_lpszSOAPReq,UserName);
// sprintf(szSOAPReq, g_lpszSOAPReq,checkTime);
// Initialize the Synchronous HTTP POST request
hr = spXMLHTTP->open(_bstr_t(_T("POST")), g_lpszSOAPEndpointURL, VARIANT_FALSE);
CHECK_HR(hr);
// Set the required Content-Type header
hr = spXMLHTTP->setRequestHeader(_bstr_t(_T("Content-Type")), _bstr_t(_T("text/xml")));
CHECK_HR(hr);
// Send the POST request, along with the SOAP request envelope text
hr = spXMLHTTP->send(_bstr_t(szSOAPReq));
CHECK_HR(hr);
if(200 == spXMLHTTP->status) //Success
{
// using MSXML DOM to process SOAP response XML text
CComQIPtr <IXMLDOMDocument2> spResponseXMLDoc;
CComPtr <MSXML2::IXMLDOMNode> spResultNode;
spResponseXMLDoc = spXMLHTTP->responseXML;
spResultNode = spResponseXMLDoc->selectSingleNode(_bstr_t(_T("//ymKqResult")));
if(spResultNode.p != NULL)
{
temp = spResultNode->nodeTypedValue;
printf("sucess\n");
}
}
else
{
printf("failed\n");
}
return temp;
}
总是发送失败，请教下，如何正确发送消息或者代码改进也可 多谢
