Node内置核心模块与第三方模块使用举例

node_use_module_example.js

var http = require('http'); //导入内置模块http

//调用内置模块http提供的createServer的API
http.createServer(function (req, res) { 
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(1337, '127.0.0.1');

console.log('Server running at http://127.0.0.1:1337/');

//--------------------------------------------------------//

var request = require('request'); //导入第三方模块request

request('http://www.google.com', function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body) // Print the google web page.
  }
})
