GET没问题，POST一个页面如http://127.0.0.1/post.php HTTP body为user=aaa&pass=bbb时，INTERNET_BUFFERS的dwBufferLength返回正确的长度17，但是lpReadBuff有时为空，有时为乱码，这是为何？

BOOL CWinHttpRequest::RecvResponseData()

{

    cout << "开始接收数据" << endl;

    m_pHttpResponse->Clear();



    BOOL bAllDone = FALSE;

    char lpReadBuff[1024];

    do

    {

        INTERNET_BUFFERS InetBuff;

        FillMemory(&InetBuff, sizeof(InetBuff), 0);

        InetBuff.dwStructSize = sizeof(InetBuff);

        InetBuff.lpvBuffer = lpReadBuff;

        InetBuff.dwBufferLength = sizeof(lpReadBuff);



        if(!InternetReadFileEx(m_hRequest, &InetBuff, IRF_ASYNC, (DWORD_PTR)m_pContext))

        {

            if(GetLastError() == ERROR_IO_PENDING)

                WaitRequestComplete();

            else

            {

                cout << "InternetReadFileEx failed, error " << GetLastError();

                cout.flush();

                return FALSE;

            }

        }

        m_pHttpResponse->AppendData(lpReadBuff, InetBuff.dwBufferLength);



        if(InetBuff.dwBufferLength == 0)

            bAllDone = TRUE;

    }

    while(bAllDone == FALSE);



    cout << "数据接收完毕" << endl;

    return TRUE;

}
