代码如下：

var request = require('request');
var cheerio = require('cheerio');
var http = require('http');


http.createServer(function (req, res) {
    request("http://www.google.com",function(error,response,body){
        if(!error && response.statusCode == 200){
            res.writeHead(200, {'Content-Type': 'text/html'}); 
            res.end(body);
        }
    })


}).listen(8080, "127.0.0.1");
