Sorry I'm late.

Facebook has disabled likes and comments through graph API.

So, I cannot test my pull request more. How do we do?

If liking and/or commenting are no longer possible, don't worry about testing them.

Hello, How's it going?

I tested to upload video object on the post using this code. however it was not working. because videos must be published to graph-video.facebook.com instead of graph.facebook.com (ref. https://developers.facebook.com/docs/graph-api/video-uploads)

So, I think this PR is only valid for uploading images now.

To upload the video, we should do like this example.

import requests


_user_id = ''    # user id (ex. 1603333222111000)
_token = ''    # Graph User API Token

url = 'https://graph-video.facebook.com/{user_id}/videos?access_token={token}'.format(
    user_id=_user_id
    token=_token
)

files = {
    'file': open('movie.mp4', 'rb')
}

response = requests.post(url, files=files).text
print(response)

Hello,

I'm using python, and also using this function to send messages:

graph.put_object(txt_id, "messages", message = 'Message goes here')

How can I send a attachment or a photo?
