Album cover photo changed to object in v2.4
mflesh1 opened this issue · comments
As of v2.4 of the Facebook graph API the cover_photo of an Album now returns a complex object instead of a string. This causes an issue when using the Album class to fetch an album and specifying the cover_photo field.
For example:
new FacebookTemplate("access token here").fetchConnections("facebook", "albums", Album.class, "id,cover_photo")
Error:

Any update on this issue?
When calling getAlbums() method from MediaOperation object, the new graph API returns this:
{ "id":"1566118282714", "can_upload":false, "count":4, "cover_photo":{ "created_time":"2017-09-07T03:25:08+0000", "id":"01213856982419289" }, "created_time":"2010-09-03T11:47:25+0000", "from":{ "name":"John Doe", "id":"01223467321201970" }, "link": ..., "name":"Album Pictures", "privacy":"everyone", "type":"album type", "updated_time":"2017-11-02T18:33:19+0000" }
The idea is to create a class in the package org.springframework.social.facebook.api named, for example, PhotoReference that extends FacebookObject and contains two fields (String id, Date createdTime). Then we can change the type of coverPhoto field, in Album class from String to PhotoReference
