问题
It looks like Facebook changed something in the last few days, I noticed the article:author information doesn't show up anymore (article:publisher still works)
https://developers.facebook.com/docs/reference/opengraph/object-type/article
It used to be working fine like this:
<meta property="article:author" content="https://www.facebook.com/yovav"/>
For example, if you share https://ufotoday.com/post/10061 on Facebook it should show the author.
UPDATE 2 It is working now, I was able to add Confirmed Publications in Linked Publications after I added my facebook website pages under a company and updated the company pages in General - Category to be "News & Media Website · Publisher".
UPDATE 1: so Linked Publications is found in the user profile settings (and not in the company facebook page settings), first I could not find website on the facebook autocomplete list, I changed page template to "business" and set "News & Media Website", "Publisher" in category. and now it is added as Confirmed Publications.
My meta data has these values now:
<meta property="article:author" content="https://facebook.com/yovav" />
<meta property="article:publisher" content="https://www.facebook.com/1677453589249352" />
However, I still cannot see the author name next to the publisher website (in the bottom left corner of facebook posts), What am I missing here?
回答1:
It appears that authors need to give permission to a publication or website (and specifically the FB page of that site) in order to be cited as the author in Facebook's byline feature.
As such, the authors needs to login to their own Facebook profile, go to Settings (for their own profile), and then click "Linked Publications" (Or just send them to this link: https://www.facebook.com/settings?tab=author_publisher )
There, they need to add the publication's (or site's) Facebook page as a "linked publication."
When I did this on my personal profile, I finally got back the byline functionality, both in the tag debugger and in actual Facebook posts.
However, I sent this info to all of our authors, and some of them do not have the particular setting page mentioned above. So YMMV.
回答2:
Some people said, if you're a Media Fanpage admin and you already confirmed your domain by Link Ownership function (Only verified page have this function), you can get author back by the new function Linked Publications.
When you finished these things, you'll see your byline back. But...
Only you(admin) can see that. Other user still can't see this byline link.
I don't know what Facebook are doing, damn it.
