I have a UDP client/server that sends a message to a server in lower or uppercase. The server receives the message and relays it back with switched cases. I can't figure out how I would instead of having the server relay it back to the first client, instead sending it to a client2...

首先我们先来了解两种软件协议: 1 c/s结构:全称Client/Server结构,是指客户端与服务器的结构,就像qq,微信等软件,通过客户端与服务器交互 2.B/S结构:全称Browser/Server,即浏览器与服务器结构,如火狐,谷歌等等,通过浏览器与服务器交互 这两种架构各有千秋,但都离不开网络的支持,网络编程就是在一定协议下,实现...

Server端: socket() bind() listen() accept() recv() Client端: socket() connect() send() 本文着重介绍Server端的socket()过程。 用户使用socket时,首先会调用socket()函数创建一个socket。在lwip中实际调用的就是lwip_socket()函数。 代码如下: ...

因为是UDP通讯,所以在程序中要建立一个UDP Socket,设置Server Socket的属性,不断的接收UDP数据报。然后验证接收到的数据报的有效性,并在程序中解析数据报。 5.2 协议开发 Protocol协议是公共的插件协议,平台能够介入的设备协议继承自该类,然后把数据解析的过程在代码里完成即可。在下述的代码片段中,比较重要的设计就...
