//======================================================================================================
// 函 数 名：SocketSend
// 功能描述：自己封装的HTTP请求方法，可以根据需要衍生出DoPut、DoPost、DoGet、DoDelete
// 输入参数：cMsgSend:要发送的消息
//           nMsgSendLen:要发送的消息长度
// 输出参数：cMsgRecv:需要向对端发送的消息
// 输入/输出参数：nRecvMsgLen: cMsgRecv的长度/实际接收到的长度
// 返回参数：1：成功
//           0：失败
// 创建日期：
// 修改日期：
// 作    者：
// 附加说明：由于CSocket和CHTTPConnect类不能很好的支持超时的设置，因此这里使用windows socket方法来实现通信
