即使我具有身份验证，Facebook JS API上的权限错误也无法发表评论

Question

I am attempting to POST a comment with the FB JS API.

FB.api("/" + myFBPageId + "/comments", "post", {
  "fb:explicitly_share": true
  "message": contents
}, function(response) { console.log(response) })

Unfortunately, even though I have the both publish_actions and publish_stream permissions, I get this exception:

"message":"(#200) Permissions error","type":"OAuthException","code":200

Um, what? Why? I have tested and I am authed with FB on the site. I just double checked with this:

FB.login(function(response) {
  console.log(response);
}, {scope: 'publish_stream'});

So my question is, what is the permissions error here? How do I fix it?

I am attempting to POST a comment

you are just giving the page id. How would the facebook know that to which feed, it should comment? So, you should provide facebook the feed-id instead of the page where you wan t tp post a comment. Here's the correct syntax if you want to post comment on a feed :

/POST_ID/comments , instead of /PAGE_ID/comments

And, if you meant to post a feed instead of a comment, you should use-

/PAGE_ID/feed
