如何查询Facebook用户发布的所有评论？

Question

换句话说，对于任何给定的Facebook用户，我如何针对任意数量的URL（在查询时未知）检索所有公共评论？

Answer 1

You can't query comments by user id alone. As you can see from the FQL Comment table, fromid (ie the user submitting a comment) is not indexable. To query Comments you would require atleast one of the following which could be used in conjunction with fromid :

xid The external ID of the fb:comments being queried. You can specify more than one XID.

object_id The object_id of an object on Facebook. This can be a video, note, link, photo, or photo album. Note that for photos and albums, the object_id must be queried from the photo and album FQL tables. Note that in the photo and album tables, object_id is a different field from pid and aid. You must specify either an xid or an object_id.

post_id The ID of the post in the stream.
