c++ - 使用 WSE 时无法从 C++ 客户端访问 Web 服务

Question

我正在尝试从 C++ 应用程序访问 .net Web 服务(内置于 vs 2008)。我正在使用 IXMLHttpRequest 访问该服务。以下是相关代码:

 MSXML::IXMLHttpRequestPtr httpReq( _uuidof(MyXMLHTTPRequest));
_bstr_t  HTTPMethod ;
_variant_t noAsync = _variant_t( (bool)false );

HTTPMethod = _bstr_t( "POST" );    
httpReq->open(HTTPMethod ,"webservice address",noAsync);   
httpReq->setRequestHeader("Content-Type", "application/soap+xml");

CString szRequest;
szRequest = "SOAP string";   

VARIANT vRequest;
vRequest.vt = VT_BSTR;
vRequest.bstrVal = szRequest.AllocSysString();

httpReq->send(vRequest);
BSTR strText;

_bstr_t bsResponse = httpReq->responseText;

但是，当我在 web.config 文件中添加以下行时，出现了 soap 异常。为什么会发生这种情况，解决方案是什么？如何访问使用 WSE 的服务？

   <webServices>
  <soapExtensionTypes>
    <add type="Microsoft.Web.Services2.WebServicesExtension, Microsoft.Web.Services2, Version=2.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxx"/>
  </soapExtensionTypes>
</webServices>

我收到以下异常:

<soap:Fault>
<faultcode>soap:Server</faultcode><faultstring>System.Web.Services.Protocols.SoapHeaderException: Server unavailable, please try later ---&gt; System.Threading.ThreadAbortException: Thread was being aborted.
   at System.Threading.Thread.AbortInternal()

Answer 1

SoapHeaderException: Server unavailable, please try later

这不是问题吗？也许问题是当您修改 web.config 时 Web 服务没有启动。
