node.js - Nodejs 中的处理程序响应

Question

我是 NodeJS 新手，我正在编写一个示例:

function test(req,res){
    var path = urls[Math.floor(Math.random()*urls.length)];
    console.log("try to redirect to:"+path);
    http.get(path,function(res_server){
        //how to send the data from res_server to res
    });
}

urls 是一个 url 数组。

我想知道如何将数据从res_server发送到原始客户端响应？

顺便说一句，网址可能是 http 或 https。

var urls=["url1","url2","url3"];
var path = urls[Math.floor(Math.random()*urls.length)]; // find an random item from the array

好的，这是完整的简单测试脚本:

var http=require("http");
http.createServer(function(req, res1) {
  var url = 'http://www.google.com.hk/images/srpr/logo11w.png';

  var hp=require("http");
  hp.get(url, function(res2) {
    res2.pipe(res1);
  });
}).listen(3000);

它可以工作，但如果您将 http://www.google.com.hk/...logo..png 更改为 https:/www.google... .png

它会抛出错误:

http.js:1840
    throw new Error('Protocol:' + options.protocol + ' not supported.');
          ^
Error: Protocol:https: not supported.

Answer 1

将 var http = require('http'); 更改为 var http = require('https');
