使用 axios 重定向后如何获取着陆页 URL [英] how to get the landing page URL after redirections using axios

问题描述

使用 NodeJS，如果我使用 maxRedirects = 5 的 axios，如果我输入的 URL 将被重定向到另一个 URL，我如何从最终登录页面获取该 URL?在 HTTP 标头中，当有 HTTP 200 代码时，着陆页没有标头字段.

Using NodeJS, If I use axios with maxRedirects = 5, If I type a URL that will be redirected to another URL, how can I get the URL from the final landing page? In HTTP headers, when there is an HTTP 200 code, there is no header field for the landing page.

示例:如果我使用:

axios.get('http://stackoverflow.com/',config)
.then(function(response) { console.log(response);}

axios 会自动重定向到 https://stackoverflow.com.那么，如何获得最终的 URL 值https://stackoverflow.com"?

axios will automatically redirect to https://stackoverflow.com. So, how can get the final URL value "https://stackoverflow.com"?

我是否应该在返回的对象响应"中进行调查并从域和 URI 重新创建完整的 url?

Should I investigate in the returned object "response" and recreate the full url from domain and URI?

推荐答案

这是我关于 NodeJS 的快速而肮脏的解决方案.起始网址是 http://www.stackoverflow.com/questions/47444251/how-to-get-the-landing-page-url-after-redirections-using-axios ，最终登陆网址是https://stackoverflow.com/questions/47444251/how-to-get-the-landing-page-url-after-redirections-using-axios 请在下面找到获取登陆 URL 的技巧.

Here is my quick and dirty solution on NodeJS. The starting URL is http://www.stackoverflow.com/questions/47444251/how-to-get-the-landing-page-url-after-redirections-using-axios , the final landing URL is https://stackoverflow.com/questions/47444251/how-to-get-the-landing-page-url-after-redirections-using-axios Please find the trick below to get the landing URL.

axios.get('http://www.stackoverflow.com/questions/47444251/how-to-get-the-landing-page-url-after-redirections-using-axios').then(function(response) {
      console.log(response.request.res.responseUrl);
     }).catch(function(no200){
      console.error("404, 400, and other events");
     
    });

response.request.res.responseURL 是 axios 返回的 JSON 对象中的正确字段.如果您从浏览器运行 axios，请使用 console.log(response.request.responseURL);

response.request.res.responseURL is the right field in the JSON object that is returned by axios. If you run axios from a browser use console.log(response.request.responseURL);
