Support Get favicon

[jc955]

hi, can feed-extractor, oEmbed Extractor support crawling to favicon URL like article-extractor?

@kk7771 thank you for your suggestion. I see two reasons not to do so:

• feed-extractor and oembed-extractor do not touch the HTML page where the article is presented. Therefore, another request will be needed to download. This is different from article-extractor, which has to download the HTML first.
• feed-extractor returns a list of news entries coming from the same website, so you only need to get favicon.ico for that website once. You can save these favicons along with a list of RSS urls as static files, instead of dynamic fetching.

You can get website favicon with Google S2. Just give it a domain or the whole URL, it will provide you the favicon to display on your view, e.g:

• https://www.google.com/s2/favicons?domain=github.com
• https://www.google.com/s2/favicons?domain=x.com
