楼主

IXMLHTTPRequestPtr->responseText 返回的XML怎么会不完全啊? [求助] IXMLHTTPRequestPtr->responseText 返回的XML怎么会不完全啊? 我的代码是 bool accessingWebService(_bstr_t command_invoker_service_namespace,  _variant_t user_name,        _variant_t password, _variant_t mac, _variant_t user_ip, LPSTR sessionID) {  IXMLHTTPRequestPtr pIXMLHTTPRequest = NULL;  BSTR bstrString = NULL;  HRESULT hr;  try {   hr = CoInitialize(NULL);   SUCCEEDED(hr) ?

这是返回的结果: "<?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body>   <ns1:getSessionIDResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="http://localhost:8080/wci/CommandInvoker.jws">    <ns1:getSessionIDReturn xsi:type="xsd:string">7B5A322B725A52F6AE9D181DDA91DD79</ns1:getSessionIDReturn>   </ns1:getSess" "7B5A322B725A52F6AE9D181DDA91DD79"这一串就是我调用Web service 返回的结果,也是我要得到的

改为这样就可以了: ...... hr = pIXMLHTTPRequest->send(lpstrBody);   SUCCEEDED(hr) ? S_OK : throw hr;   if(pIXMLHTTPRequest->status != 200 && pIXMLHTTPRequest->status != 207)   {    return false;   }   MSXML2::IXMLDOMDocument * pXMLDoc;   MSXML2::IXMLDOMNode * pXDN;   IDispatch * ppBody;   hr = pIXMLHTTPRequest->get_responseXML(&ppBody);   SUCCEEDED(hr) ? S_OK : throw hr;   hr = CoInitialize(NULL);   SUCCEEDED(hr) ? S_OK : throw hr;   hr = CoCreateInstance(CLSID_DOMDocument, NULL,    CLSCTX_INPROC_SERVER,    IID_IXMLDOMDocument,    (void**)&pXMLDoc);   SUCCEEDED(hr) ? S_OK : throw hr;   hr = ppBody->QueryInterface(IID_IXMLDOMNode, (void **)&pXDN);   SUCCEEDED(hr) ? S_OK : throw hr;     MSXML2::IXMLDOMNode * envelopeNode;   hr = pXDN->get_lastChild(&envelopeNode);   SUCCEEDED(hr) ? S_OK : throw hr;   MSXML2::IXMLDOMNode * bodyNode;   hr = envelopeNode->get_firstChild(&bodyNode);   SUCCEEDED(hr) ? S_OK : throw hr;   MSXML2::IXMLDOMNode * getSessionIDResponseNode;   hr = bodyNode->get_firstChild(&getSessionIDResponseNode);   SUCCEEDED(hr) ? S_OK : throw hr;   MSXML2::IXMLDOMNode * getSessionIDReturnNode;   hr = getSessionIDResponseNode->get_firstChild(&getSessionIDReturnNode);   SUCCEEDED(hr) ? S_OK : throw hr;   MSXML2::IXMLDOMNode * sessionIDTextNode;   hr = getSessionIDReturnNode->get_firstChild(&sessionIDTextNode);   SUCCEEDED(hr) ? S_OK : throw hr;   hr = sessionIDTextNode->get_nodeValue(returnValue);   SUCCEEDED(hr) ? S_OK : throw hr; ......
