MFC 发送HTTP请求获取Set-Cookie不完全

我想模拟发送Get请求，获取服务器传回的Set-Cookie值，可是获取到的Set-Cookie不完全。
下面是我用火狐的FireDebug抓到的数据：
URL是：

 http://my.37.com/api/login.php?callback=jQuery18301289508974426815_1425523200459&action=login&login_account=dazhewang&password=111111&ajax=0&remember_me=1&save_state=1&ltype=1&_=1425523232168

请求头是：

 GET /api/login.php?callback=jQuery18301289508974426815_1425523200459&action=login&login_account=dazhewang&password=111111&ajax=0&remember_me=1&save_state=1&ltype=1&_=1425523232168 HTTP/1.1

Accept-Encoding: gzip, deflate

响应头信息是：

下面是我的代码：

 CInternetSession session;
    INTERNET_PORT nPort = 80;
    try {
        CHttpConnection* pHttpConnect = session.GetHttpConnection(_T("my.37.com"), nPort);
        if (pHttpConnect) {
            CHttpFile* pFile = pHttpConnect->OpenRequest(CHttpConnection::HTTP_VERB_GET, _T("/api/login.php ?"));  //"/api/login.php ?"的问号应该是不要的吧，我尝试去掉？后，代码结果不变
            if (pFile) {
                pFile->AddRequestHeaders(L"GET /api/login.php ? callback = jQuery18301289508974426815_1425523200459&action = login&login_account = dazhewang&password = 111111 & ajax = 0 & remember_me = 1 & save_state = 1 & ltype = 1 & _ = 1425523232168 HTTP / 1.1"); //这里的参数信息是否是这么添加的？
                pFile->AddRequestHeaders(_T("Accept : */*"));
                pFile->AddRequestHeaders(_T("Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3"));
                pFile->AddRequestHeaders(_T("Referer: http://www.37.com/"));
                pFile->AddRequestHeaders(_T("User-Agent: Mozilla / 5.0 (Windows NT 6.1; WOW64; rv:36.0) Gecko / 20100101 Firefox / 36.0"));
                pFile->AddRequestHeaders(_T("Accept-Encoding: gzip, deflate"));
                pFile->AddRequestHeaders(_T("Host: my.37.com"));
                pFile->AddRequestHeaders(_T("Connection: keep-alive"));
                pFile->AddRequestHeaders(_T("Cache - Control: no - cache"));
                //TCHAR szRequest
                //pFile->SendRequest(NULL, 0, szRequest, MAX_COUNT*sizeof(TCHAR));
                pFile->SendRequest(); //这句代码需要加参数吗？我这里没有要额外添加的信息了
                CString strStatus(_T(""));
                if (pFile->QueryInfo(HTTP_QUERY_RAW_HEADERS_CRLF, strStatus)) {
                    AfxMessageBox(strStatus);
                }
            }
            pFile->Close();
            delete pFile;
            pFile = NULL;
        }
        return TRUE;
    }
    catch (CInternetException* e)
    {
        e->ReportError();
        e->Delete();
        return FALSE;
    }

返回的响应结果如下：

Set-Cookie值只1条，请问大神们这是什么原因啊？求解答，万分感谢！！！（由于是新账号，没悬赏分，非常抱歉）

解决方案

把你代码发的包也抓包，然后跟l浏览器的对比。看缺少什么数据。

解决方案二：

用fiddler仔细调试下，看看是不是编码的问题

解决方案三：

谢谢回答啊，你的意思是说有可能没有用utf-8编码吗？我试了试，多加了条

 pFile->AddRequestHeaders(_T("Content-Type: text/html; Charset=UTF-8"));

结果也一样，是不是我加错地方了？

解决方案四：

同样出现跟你一样的问题,暂时还没有得到解决 你QQ多少?我的是86612150 一起交流下

我觉得不是头部的问题,因为我的代码和你差不多,我获取的到cookie也是不完整的,这个好像是个bug,不知道怎么搞
