第一个服务器端的node.js

1. 首先打开node终端

> var http = require('http');
undefined
> http.createServer(function (req, res) {
... res.writeHead(200, {'Content-Type': 'text/plain'});
... res.end('Hello Shengtai\n');
... }).listen(8124, "127.0.0.1");
{ domain:
   { domain: null,
     _events: { error: [Function] },
     _maxListeners: undefined,
     members: [] },
  _events:
   { request: [Function],
     connection: [Function: connectionListener],
     clientError: [Function] },
  _maxListeners: undefined,
  _connections: 0,
  _handle: null,
  _usingSlaves: false,
  _slaves: [],
  allowHalfOpen: true,
  pauseOnConnect: false,
  httpAllowHalfOpen: false,
  timeout: 120000 }
> console.lgo('Server running at http://127.0.0.1:8124/');
TypeError: undefined is not a function
    at repl:1:9
    at REPLServer.defaultEval (repl.js:132:27)
    at bound (domain.js:254:14)
    at REPLServer.runBound [as eval] (domain.js:267:12)
    at REPLServer.<anonymous> (repl.js:279:12)
    at REPLServer.emit (events.js:107:17)
    at REPLServer.Interface._onLine (readline.js:214:10)
    at REPLServer.Interface._line (readline.js:553:8)
    at REPLServer.Interface._ttyWrite (readline.js:830:14)
    at ReadStream.onkeypress (readline.js:109:10)
> console.log('Server running at http://127.0.0.1:8124/');
Server running at http://127.0.0.1:8124/
undefined
>

 

2. 其次打开浏览器输入http://localhost:8124/

3. 最后可以看到结果： Hello Shengtai
