1.server: 网络套接字 本地套接字 2. client: 网络套接字 本地套接字 六、UDP用户数据报的首部格式: UDP 用户数据报的首部十六进制表示是:06 32 00 45 00 1C E2 17 七、使用 UDP 的这个服务器程序是什么? 源端口:1586(前4个字节0632)
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...
