分析http协议的Request请求，可以写自己的文件上传组件。-http protocol analysis of the Request request, can write their own file upload component.

HTTP是一个基于文本的协议，用于通过Web浏览器来检索Web页面。大多数情况下，如果你位于一个局域网连接时，你是在一个代理服务器之后；这个代理服务器在某一端口运行一个HTTP代理。在你的Internet Explorer的连接选项中，你可以按需要说明局域网的设置。这个代理服务器运行一个基于文本的协议，你只能从外部网格中得到HTTP相关的数据。但注意，有一个小漏洞，通过它你可以穿过HTTP，连接到外部世界，得到任何基于二进制协议的数据，甚至基于你自己的协议。这就是通过HTTPS。-HTTP is a text-based protocol for a Web browser to access Web pages. In most cases, if you are located in a LAN connection, you are after a proxy server; The proxy server port in a run an HTTP proxy. In your Internet Explorer connectivity options, you may press the need to explain LAN configuration. The proxy server running on a text of the agreement, you can only from the outside grid to be related to the HTTP data. But note that there are a small loophole through which you can pass through HTTP, connect to the outside world, any agreement based on the binary data, or even on your own agreement. It is through HTTPS.

基本过程如下： 1. 利用ntp服务器获取网络时间     QUdpSocket udp_sock;     udp_sock.connectToHost("time.windows.com",123); 2. 阻塞等待连接成功     if(udp_sock.waitForConnected(60000))     {         ...     } 3. 发送时间请求         udp_sock.write(time_req);         udp_sock.flush(); 4. 阻塞等待消息返回         if(udp_sock.waitForReadyRead(120000))         {             ...         } 说明：此过程等待时间可能较长，出现连接失败的情况也比较常见。
