Ruby Requires Chilkat v11.0.0+

Read a Single Facebook Post

See more Facebook Examples

Demonstrates how to read the contents of a single Facebook post. A post is an individual entry in a profile's feed. The profile could be a user, page, app, or group. Ruby

require 'chilkat'

success = false

#  This example requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

#  This example assumes a previously obtained an access token
oauth2 = Chilkat::CkOAuth2.new()
oauth2.put_AccessToken("FACEBOOK-ACCESS-TOKEN")

rest = Chilkat::CkRest.new()

#  Connect to Facebook...
success = rest.Connect("graph.facebook.com",443,true,true)
if (success == false)
    print rest.lastErrorText() + "\n";
    exit
end

#  Provide the authentication credentials (i.e. the access key)
rest.SetAuthOAuth2(oauth2)

#  This example assumes a post id was already retrieved.
#  For example, it could've been retrieved by reading the user's feed:
#  See Parsing the Facebook User Feed for code showing how to parse the JSON feed content.

sbPath.Append(postId)

#  Select the fields we want.
#  This example will select almost all the possible fields.
#  See https://developers.facebook.com/docs/graph-api/reference/post/
rest.AddQueryParam("fields","id,message,created_time,caption,description,from,link,name,object_id,picture,place,privacy,properties,shares,source,status_type,story,targeting,to,type,updated_time,with_tags")
