代码未经测试

var http = require('http')
var opt = {
 host:'这里放代理服务器的ip或者域名',
 port:'这里放代理服务器的端口号',
 method:'POST',//这里是发送的方法
 path:' https://www.google.com',     //这里是访问的路径
 headers:{
  //这里放期望发送出去的请求头
 }
}
//以下是接受数据的代码
var body = '';
var req = http.request(opt, function(res) {
  console.log("Got response: " + res.statusCode);
  res.on('data',function(d){
  body += d;
 }).on('end', function(){
  console.log(res.headers)
  console.log(body)
 });

}).on('error', function(e) {
  console.log("Got error: " + e.message);
})
req.end();




example:

var url = "https://maps.googleapis.com/maps/api/place/textsearch/json?query=chengdu&key=AIzaSyADem01JiuaQddzqagjdy41ep6SbhxBl8s";

 

var http = require('http')
var opt = {
host:'127.0.0.1',
port:'8087',
method:'get',//这里是发送的方法
path:url, //这里是访问的路径
headers:{
'Accept-Language':'zh-CN,zh;q=0.8',
'Host':'maps.googleapis.com'
}
}
//以下是接受数据的代码
var body = '';
var req = http.request(opt, function(res) {
console.log("Got response: " + res.statusCode);
res.on('data',function(d){
console.log(d);
body += d;
}).on('end', function(){
console.log(res.headers)
console.log(body)
});

}).on('error', function(e) {
console.log("Got error: " + e.message);
})
req.end();

可用代码但测试50个并发的情况下图片损失率很大原因还需要待一步研究
