CHttpConnection POST数据格式怎么写

[richiezhao]

我用CHttpConnection以post的方式连接web服务器，服务器显示连接上了，但是post的数据deviceName没取到值，以下是我的连接服务器发送请求的代码：
m_HttpServerConn = m_ConnectSession.GetHttpConnection(strServerName,nPort);
m_HttpFile = m_HttpServerConn->OpenRequest(CHttpConnection::HTTP_VERB_POST,
strObject, NULL, 1, NULL, NULL, DWHTTPREQUESTFLAGS);
CString strHeaders = _T("Content-Type: application/x-www-form-urlencoded");
char form[] = "deviceName=aaaaa"; //post发送的参数，但服务端得不到aaaaa这个值。
m_HttpFile->SendRequest(strHeaders,(LPVOID)form,17);
DWORD dwRet;
m_HttpFile->QueryInfoStatusCode(dwRet);

请问这个是怎么回事，是不是我post的数据格式有问题。我的web应用服务器是用tomcat。

你的HTTP头不对啊
CString strHeaders = _T("Content-Type: application/x-www-form-urlencoded");
这句相当于将HTTP头里的其他信息都覆盖了

你应该是希望在http头里面加这一行，用m_HttpFile->AddRequestHeaders(。。。)

然后m_HttpFile->SendRequest(NULL,0,(LPVOID)form,17);

CInternetSession   m_winet(NULL,1,INTERNET_OPEN_TYPE_DIRECT,NULL,NULL,0);   
  CHttpConnection   *pConnection;   
  CHttpFile   *pFile;   
  pConnection   =   m_winet.GetHttpConnection("expert.csdn.net");   
    
  CString   strHeaders,   tempStr,str;   
  str="name=*******&pass=******&type=1";   
  //strHeaders   =   _T("Content-Type:   application/x-www-form-urlencoded");   
    
  pFile=pConnection->OpenRequest(CHttpConnection::HTTP_VERB_POST,   
  "/member/logon.asp");   
  pFile->AddRequestHeaders("Accept:   image/gif,   image/x-xbitmap,   image/jpeg,   image/pjpeg,   application/vnd.ms-powerpoint,   application/vnd.ms-excel,   application/msword,   */*");   
  pFile->AddRequestHeaders("User-Agent:   Mozilla/4.0   (compatible;   MSIE   5.01;   Windows   NT   5.0)");   
  pFile->AddRequestHeaders("Content-Type:   application/x-www-form-urlencoded");   
  pFile->SendRequest(   
  NULL,0,   
  (LPVOID)(LPCTSTR)str,   str.GetLength());   

[CoderOfVC]

pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,				//请求服务器
									strObject,NULL,1,
									NULL,NULL,INTERNET_FLAG_EXISTING_CONNECT  | INTERNET_FLAG_RELOAD); 
		if(pFile == NULL)															//如果请求失败的话
		{
			SetLastErrorMsg();
			return CF_RET_NETERROR;
		}
		pFile -> AddRequestHeaders("Content-Type: application/x-www-form-urlencoded"); 
		pFile -> AddRequestHeaders("Accept: */*"); 
		pFile -> SendRequest(NULL, 0, (LPTSTR)(LPCTSTR)strPostData, strPostData.GetLength());	//POST数据

		BOOL bSuccess = pFile->QueryInfo(											//查询POST操作是否成功
			HTTP_QUERY_STATUS_CODE|HTTP_QUERY_FLAG_NUMBER,
			&dwStatus, &dwBuffLen);

我用的一些代码，看有没有帮助

这个刚试过了，不过还是不行，服务端报错了，那个参数能看到，但是参数的值没有。
