nodejs学习：net模块

官方API文档地址：https://nodejs.org/api/net.html

1. 创建一个server.js

    1 var net = require(‘net‘);
    2 var PORT  = 8099;
    3 var HOST = ‘127.0.0.1‘
    4
    5 var server = net.createServer();
    6 server.on(‘connection‘, function(client) {
    7     client.name = client.remoteAddress + ‘:‘ + client.remotePort
    8     client.write(‘Hi ‘ + client.name + ‘!\n‘);
    9
   10     client.on(‘data‘, function(data) {
   11         client.write(data);
   12     })
   13     client.on(‘end‘, function() {
   14         client.write(‘Bye ‘ + client.name + ‘!\n‘);
   15     })
   16
   17     client.on(‘error‘, function(e) {
   18         console.log(‘error:‘+ e.message);
   19     })
   20 });
   21
   22 server.on(‘listening‘, function() {
   23     console.log(‘Server is listening on port‘, PORT);
   24 });
   25 server.listen(PORT,HOST);
