//给指定url发请求, 返回请求后的结果

string CAutoPatchDlg::SendURLPost(string strServerName, string strFormActionUrl, string strPostStr)

{

	CString strFormData(strPostStr.c_str());    // 需要提交的数据

CInternetsess sess("HttpClient");

//连结超时没效果的, 发送超时与接收超时有用, 连结超时可以用多线程WaitForSingleObject来实现

sess.SetOption(INTERNET_OPTION_CONNECT_TIMEOUT, 5000); // 5000毫秒的连接超时

sess.SetOption(INTERNET_OPTION_SEND_TIMEOUT, 5000); // 5000毫秒的发送超时

sess.SetOption(INTERNET_OPTION_RECEIVE_TIMEOUT, 5000); // 5000毫秒的接收超时

sess.SetOption(INTERNET_OPTION_DATA_SEND_TIMEOUT, 5000); // 5000毫秒的发送超时

sess.SetOption(INTERNET_OPTION_DATA_RECEIVE_TIMEOUT, 5000); // 5000毫秒的接收超时

sess.SetOption(INTERNET_OPTION_CONNECT_RETRIES, 1); // 1次重试

	CString strHeaders = _T("Content-Type: application/x-www-form-urlencoded"); // 请求头

	CHttpConnection *pConnection = sess.GetHttpConnection(strServerName.c_str());

	CHttpFile *pFile = pConnection->OpenRequest(CHttpConnection::HTTP_VERB_POST, strFormActionUrl.c_str());

	CString strSentence, strGetSentence = "";

	if(pFile)

	{

		BOOL result = pFile->SendRequest(strHeaders, (LPVOID)(LPCTSTR)strFormData, strFormData.GetLength());

		while(pFile->ReadString(strSentence))  // 读取提交数据后的返回结果

			strGetSentence = strGetSentence + strSentence + char(13) + char(10);

		pFile->Close();

		delete pFile;

		sess.Close();

		return string(strGetSentence.GetBuffer());

	}

	return "";

}

string strResult = "";

	string strServerName = "www.test.com";

	string strFormActionUrl = "/index.php";

	string strPostData = "username=" + strUserName + "&password=" + strPassword;

strResult = SendURLPost(strServerName, strFormActionUrl, strPostData);

这个方法有个缺陷, 网络不通SendRequest会等待几十秒, 感觉像卡死了似的.
