CHttpFile POST 时 Cookie 疑问

POST 的例子：

http://bbs.csdn.net/topics/310014521

bool PostContent(CString strUrl, const CString &strPara, CString &strContent, CString &strDescript)
{
try{

strDescript = "提交成功完成！";
bool bRet = false;
CString strServer, strObject, strHeader, strRet;
unsigned short nPort;
DWORD dwServiceType;
if(!AfxParseURL(strUrl, dwServiceType, strServer, strObject, nPort))
{
strDescript = strUrl + "不是有效有网络地址！";
return false;
}
CInternetSession sess;//Create session

CHttpFile* pFile;
//////////////////////////////////////////////
CHttpConnection *pServer = sess.GetHttpConnection(strServer, nPort);
if(pServer == NULL)
{
strDescript = "对不起，连接服务器失败！";
return false;
}
pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,strObject,NULL,1,NULL,NULL,INTERNET_FLAG_EXISTING_CONNECT);
if(pFile == NULL)
{
strDescript = "找不到网络地址" + strUrl;
return false;
}

// pFile -> AddRequestHeaders("Content-Type: text/xml; charset=utf-8");
pFile -> AddRequestHeaders("Content-Type: application/x-www-form-urlencoded");
pFile -> AddRequestHeaders("Accept: */*");
pFile -> SendRequest(NULL, 0, (LPTSTR)(LPCTSTR)strPara, strPara.GetLength());

CString strSentence;
DWORD dwStatus;
DWORD dwBuffLen = sizeof(dwStatus);
BOOL bSuccess = pFile->QueryInfo(
HTTP_QUERY_STATUS_CODE|HTTP_QUERY_FLAG_NUMBER,
&dwStatus, &dwBuffLen);

if( bSuccess && dwStatus>= 200 && dwStatus<300)
{
char buffer[2049];
memset(buffer, 0, 2049);
int nReadCount = 0;
while((nReadCount = pFile->Read(buffer, 2048)) > 0)
{
strContent += buffer;
memset(buffer, 0, 2049);
}
bRet = true;
}
else
{
strDescript = "网站服务器错误" + strUrl;
bRet = false;
}
////////////////////////////////////////
pFile->Close();
sess.Close();
return bRet;
}
catch(...)
{
int nCode = GetLastError();
strDescript.Format("向服务器post失败！错误号：%d", nCode);
return false;
}
}

但是在 POST 带有Cookie时使用那种方式会得不到想要的结果，解决办法为：

CHttpFile 设置cookie的疑问我在模拟给百度发get数据http://www.baidu.com/s?wd123想加入Cookie: BAIDUID

CHttpFile 设置cookie的疑问
我在模拟给百度发get数据
http://www.baidu.com/s?wd=123
想加入Cookie: BAIDUID=11111111111111111111111111111111:FG=1; USERID=222222222222222222222222; J_MY=1

但是抓包怎么都看不到这个信息。

C/C++ code

....pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_GET,strPara,NULL,1,NULL,NULL,INTERNET_FLAG_EXISTING_CONNECT); pFile->AddRequestHeaders("Accept: */*"); pFile->AddRequestHeaders("Accept-Language: zh-cn");pFile->AddRequestHeaders("User-Agent: Mozilla/4.0");pFile->AddRequestHeaders("Connection: Keep-Alive");pFile->AddRequestHeaders("Cookie: BAIDUID=11111111111111111111111111111111:FG=1; USERID=222222222222222222222222; J_MY=1");....

抓包后发现Cookie: BAIDUID=90167E2729B1C6B3C51D254097849AA8:FG=1; USERID=1b10bc91b31e48a202df443d; J_MY=1

不知道怎么回事了。

[解决办法]
pServer->OpenRequest加上INTERNET_FLAG_NO_COOKIES
OpenRequest(CHttpConnection::HTTP_VERB_GET,strPara,NULL,1,NULL,NULL,INTERNET_FLAG_EXISTING_CONNECT|INTERNET_FLAG_NO_COOKIES);
