You need to submit your app for review with required permission to access Facebook posts of page in which you aren’t admin; in live mode
This is a basic example of scrapping comments of a facebook post using python and facebook sdk
I hope you have python and know how to install a package.
Lets install facebook using pip
pip install facebook-sdk
We are proceeding directly in python
Before that we need an access token to connect to facebook.
Get the access token from here: https://developers.facebook.com/tools/accesstoken/
Access token is the pretty long string inside the textbox on the side where it is written “Access Token”
Now lets get those comments
graph = facebook.GraphAPI(access_token=’your pretty long string which you have copied now’)
post = graph.get_object(id = ‘post id’)
You can get the post id, by opening an url of a post in facebook
If url to a post is https://www.facebook.com/TimesofIndia/posts/10153947250687139 then, “10153947250687139” is the post id
This will print bunch of details about the post including first 10 likes and first 10 comments
If you just need to see the comments
This will show just the comments.
If you need the remaning comments/likes, you will need to iterate the “cursors”, which doesn’t cover in basics. So just stopping here.
If you need further clarifications, please comment. If you wish to have Part 2 of this post, comment.
