I use graph api to publish a comment on a post in a facebook group. Before October 18, 2017, this method still working normally:
POST /v2.10/{object-id}/comments HTTP/1.1
Host: graph.facebook.com
message=This+is+a+test+comment
https://developers.facebook.com/docs/graph-api/reference/v2.10/object/comments
But after October 18, 2017, this method has an error:
(#3) Publishing comments through the API is only available for page access tokens
It seems that facebook blocked this function: https://developers.facebook.com/docs/graph-api/changelog#v2_10
How can I fix it? Because I need to comment on a post in a facebook group in my system.
