I have a feed that I'd like to extract to content of the posts from: http://feeds.feedburner.com/oogionet
I'd like to parse each post title, publish date and feature image. I have a problem with this feed because it doesn't contain the feature images, so as far as I understand - I can't parse them...
However, when I try to get the feed contents using Feedly, like this: https://cloud.feedly.com/v3/streams/contents?count=5&streamId=feed/http://feeds.feedburner.com/oogionet, the images do appear in it (in each visual node).
So I'd like to ask, how do they do it? This feed doesn't contain the posts' images so how can Feedly get them?
It looks like Feedly crawls the HTML page (https://www.oogio.net/?p=26620 for the first item), and looks for Open Graph content. When viewing the source for that page, you'll see a <meta> tag like this:
<meta property="og:image" content="https://www.oogio.net/wp-content/uploads/2020/03/chocolate_rice_krispies_snack2-s.jpg" />
This tag is used by providers like Slack and Facebook to show images on posts, and I'm pretty sure that it's how Feedly gets the image.
