免费建站工具有哪些,惠州仲恺住房和城乡建设局网站,网页版微信二维码传送助手,怎么选择郑州网站建设写了一个socket的程序#xff0c;可以和本地的服务器进行通信#xff0c;要先和服务器建立链接#xff0c;然后发送登录信息#xff0c;验证成功#xff0c;就可以和服务器通信了 1 页面截图 2 点击链接服务器#xff0c;可以链接服务器#xff0c;服务器的ip地址为可以和本地的服务器进行通信要先和服务器建立链接然后发送登录信息验证成功就可以和服务器通信了 1 页面截图 2 点击链接服务器可以链接服务器服务器的ip地址为127.0.0.1 端口为 12345 3 点击链接服务器之后打印信息如下 4 点击登录会向服务器发送登录信息 iam:zhangsan, 然后会客户端会显示登录成功 5 比如输入chongqingyoudian 6 在服务器控制台就能看到客户端发送的信息 客户端代码如下 1 //2 // ViewController.m3 // 05.聊天室4 //5 // Created by apple on 14/12/5.6 // Copyright (c) 2014年 heima.
