Perl 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. Perl

use chilkat();

$success = 0;

#  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 = $rest->Connect("graph.facebook.com",443,1,1);
if ($success == 0) {
    print $rest->lastErrorText() . "\r\n";
    exit;
}

#  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.

#  Select the fields we want.
#  This example will select almost all the possible fields.
