Trying To Read Friends Links in Facebook Using FQL: Why do some friends return an empty set?

阅读更多关于 Trying To Read Friends Links in Facebook Using FQL: Why do some friends return an empty set?

问题 When trying to find friends of mine that also use this app and have links from a specific site, I'm getting no results from some friends, but it works great on others. If I use the Graph API Explorer, doing something as simple as /friendid/links returns an empty set.

Anyone

Permission migration from publish_stream to publish_action

阅读更多关于 Permission migration from publish_stream to publish_action

I am wondering if you have a users permission to publish_stream and you want to publish_action from now on does publish_stream cover both or do we need to re-request the users permission? If so whats the easiest way of detecting wether they have this permission granted etc. User journey suggestions welcome. The login system I have in place is users can use with facebook or their account credentials. But some users sign up without facebook and then connect later. I don't create the session every time they login as I only need the publish_stream permission which works without needing a live user

阅读更多关于 Facebook crops open graph image in to a square

问题 I'm trying to create a custom open graph story to Facebook but I'm having some trouble getting the og:image to show properly. I'm using a 1200*630 sized image as recommended here and here but on my timeline it gets cropped in to a square from the left edge of the image. It also shows as a square in the story preview though this time it's cropped from the center. How can I get the image to show in the correct aspect ratio and size?

Facebook Open Graph Not Showing Object Title

阅读更多关于 Facebook Open Graph Not Showing Object Title

I'm having conflicting reports for our users that people that share Object Graph objects to their wall, are sometimes showing the Object title and other times not. Specifically, every test I do on my own account shows the Object Title, but on their Mobile apps - it doesn't appear. I've tested the Open Graph debugger.So I have a couple of questions: Is there a length limit on the number of characters? Does Facebook not show the whole Object.title on Mobile? Does Facebook scrap the OG tags and if it can't find them or if it timeout do they not receive them? Here is my sample OG url: https:/
