基于NodeJs搭建的Tcp服务端以及客户端连接

•  Tcp基于node环境搭建的Server服务端

• var net = require('net');
  var tcp_server = net.createServer();  // 创建 tcp server
  
  var Sockets = {};
  var SocketID = 1;
  
  // 监听 端口
  tcp_server.listen(12345,function(){
      console.log('tcp_server listening 5678');
  });
  
  //处理客户端连接
  tcp_server.on('connection',function(socket){   
      console.log(sockte.address());
      Sockets[SocketID] =socket;
      SocketID++;
      DealConnect(socket)
  })
  
  tcp_server.on('error', function (){
      console.log('tcp_server error!');
  })
  
  tcp_server.on('close', function () {
      console.log('tcp_server close!');
  })
  
  
  // 处理每个客户端消息
  function DealConnect(socket){
      socket.on('data',function(data){
          data = data.toString();
          // 向所有客户端广播消息
         for(var i in Sockets){
             Sockets[i].write(data +'aaa')
         }
          // socket.write(data);
          console.log('received data %s',data);
      })
  
      // 客户端正常断开时执行
      socket.on('close', function () {
          console.log('client disconneted!');
      })
      // 客户端正异断开时执行
      socket.on("error", function (err) {
              console.log('client error disconneted!');
          });
  }

•  Tcp基于node环境搭建的Client客户端

• var net = require('net');
  
  // 指定连接的tcp server ip，端口
  var options = {
      host : '10.10.20.162',  
      port : 6688
  }
  
  var tcp_client = net.Socket();
  
  // 连接 tcp server
  tcp_client.connect(options,function(){
      console.log('connected to Server');
      tcp_client.write('I am tcp_client of ssssss!');
  })
  
  // 接收数据
  tcp_client.on('data',function(data){
      
      console.log('received data: %s from server', data.toString());
  })
  
  tcp_client.on('end',function(){
      console.log('data end!');
      
  })
  
  tcp_client.on('error', function () {
      console.log('tcp_client error!');
  })
