如何从网站获取提要URL? [英] How to get the feed URL(s) from a website?

问题描述

按照官方文档礼貌地询问时，设置网站应指出其RSS/Atom提要的URL:

As per the official documentation, properly setup websites should indicate the URL of their RSS / Atom feed(s) when asked politely:

GET / HTTP/1.1
Host: example.com
Accept: application/rss+xml, application/xhtml+xml, text/html

当HTTP服务器(或服务器端脚本)获得此消息时，它应该将HTTP客户端重定向到提要.它应该使用HTTP来执行此操作302找到.像这样:

When an HTTP server (or server-side script) gets this, it should redirect the HTTP client to the feed. It should do this with an HTTP 302 Found. Something like:

HTTP/1.1 302 Found
Location: http://example.com/feed

我正试图得到这个答复，但是没有运气:

I'm trying to get this response, without luck:

request(
  { method: 'GET',
    url: 'https://stackoverflow.com',
    followRedirect :false,
    accept: ['application/rss+xml', 'application/xhtml+xml', 'text/html']
  }, function (error, response, body) {
    console.log('statusCode: ', response.statusCode);
  }
);

收益

statusCode: 200

如何制定我的请求，以便网站以供稿URL进行响应?

How do I formulate my request so that the website responds with the feed URL(s)?

推荐答案

网站将HTTP请求的RSS提要发送回首页以请求 application/rss + xml 接受标头中的MIME类型.您链接到的有关Mozilla的文档是我作为开发人员多年参与RSS之后从未见过的建议.

It is not common practice for websites to send back their RSS feed from an HTTP request to the home page asking for an application/rss+xml MIME type in the Accept header. That documentation on Mozilla you've linked is a suggestion I've never seen before after many years involvement in RSS as a developer.

一种用于站点识别RSS提要的更成熟且被广泛采用的方法是称为 RSS自动发现的技术..打开网站的主页，然后在 HEAD 部分中查找该标签:

A more established and widely adopted method for a site to identify its RSS feed is a technique called RSS Autodiscovery. Open the site's home page and look for this tag in the HEAD section:

<link rel="alternate" type="application/rss+xml" title="RSS"
    href="http://feeds.example.com/rss-feed">

类型属性可以是RSS，Atom或JSONFeed提要的任何MIME类型.

The type attribute can be any of the MIME types for RSS, Atom or JSONFeed feeds.
