node.js 抓取网页

var request = require('request');

//抓取body
request('http://xxx.com/', function (error, response, body) {
 if (!error && response.statusCode == 200) {
 console.log(body)
 }
 })

//实现head方法
request.head('http://xxx.com/', function (error, response, header) {

    //console.log(error)
    console.log(response)
    //console.log(header)
    if (!error && response.statusCode == 200) {
        console.log(header)
    }
})
