         "from": {
            "name": "Rabia Yalcinkaya",

推荐答案

在 actions 字段中有 link 字段(对于每个可用的操作)，它恰好包含给定帖子的永久链接.但是，在依赖它之前一定要检查它 - 它可能会改变.我只用过评论"和喜欢".

in the actions field there is the link field (for each available action) which happens to contain the permalink to the given post. However be sure to inspect this before relying on it - it might change. I've only used it with "comment" and "like".

除此之外，您还必须手动构建它.对于设置了用户名的用户(即可以通过 facebook.com/username 访问他们的个人资料，它适用于:

Apart from that you'd have to construct it manually. For users that have their username set (i.e. their profile is accessible via facebook.com/username, it works with:

 http://facebook.com/USERID/posts/POSTID

对于其他一切:

 http://www.facebook.com/permalink.php?id=USERID&v=wall&story_fbid=POSTID

来源:http://forum.developers.facebook.net/viewtopic.php?pid=316384

请注意，POSTID 的格式为 USERID_POSTID，因此您必须删除第一部分.

Note that the POSTID is in the form USERID_POSTID, so you'd have to strip the first part.
