如何从nodejs请求模块获取重定向的URL? [英] How do I get the redirected url from the nodejs request module?

问题描述

我正在尝试使用url将我使用nodejs 请求模块.

I'm trying to follow through on a url that redirects me to another page using the nodejs request module.

梳理文档，找不到重定向后检索到网址的任何内容.

Combing through the docs I could not find anything that allows me to retrieve the url after the redirect.

我的代码如下:

var request = require("request"),
    options = {
      uri: 'http://www.someredirect.com/somepage.asp',
      timeout: 2000,
      followAllRedirects: true
    };

request( options, function(error, response, body) {

    console.log( response );

});

推荐答案

有两种非常简单的方法来获取重定向链中的最后一个URL.

There are two very easy ways to get hold of the last url in a chain of redirects.

var r = request(url, function (e, response) {
  r.uri
  response.request.uri
})

uri是一个对象. uri.href包含带有查询参数的URL作为字符串.

The uri is a object. uri.href contains the url, with query parameters, as a string.

代码来自请求创建者对github问题的评论: https://github.com /mikeal/request/pull/220#issuecomment-5012579

The code comes from a comment on a github issue by request's creator: https://github.com/mikeal/request/pull/220#issuecomment-5012579

示例:

var request = require('request');
var r = request.get('http://google.com?q=foo', function (err, res, body) {
  console.log(r.uri.href);
  console.log(res.request.uri.href);

  // Mikael doesn't mention getting the uri using 'this' so maybe it's best to avoid it
  // please add a comment if you know why this might be bad
  console.log(this.uri.href);
});

这将打印 http://www.google.com/?q=foo 三次(请注意，我们从一个没有www的地址重定向到了带有www的地址.

This will print http://www.google.com/?q=foo three times (note that we were redirected to an address with www from one without).
