PHP example
https://graph.facebook.com/220439?access_token=...
<?php $app_id = YOUR_APP_ID; //this you need to change $app_secret = YOUR_APP_SECRET; //this you need to change $access_token = THE_ACCESS_TOKEN //this you get after you have done authentication $user_id = THE_USER_ID; //this you get after you have done authentication //AUTHENTICATION MUST BE DONE FIRST //see previous code samples............here is an example $app_id = "YOUR_APP_ID"; $canvas_page = "YOUR_CANVAS_PAGE_URL";
$auth_url = "http://www.facebook.com/dialog/oauth?client_id=". $app_id . "&redirect_uri=" . urlencode($canvas_page);
$signed_request = $_REQUEST["signed_request"]; // this will be passed automatically (see above) to
// your app when user invokes
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
if (empty($data["user_id"])) { // if no data given about user in signed_request info then ask user // to authorize your app to get it
// facebook will return to the canvas_page as a "call back " url //and pass the new signed_request echo("<script> top.location.href='" . $auth_url . "'</script>"); } else { $access_token = $data["oauth_token"]; //grab the oauth token sent } //ASK FOR INFORMATION ABOUT USER (assumes authentication successful) $user_getinfo_url = "https://graph.facebook.com/".$user_id . "access_token?" .$access_token $user_data = file_get_contents($user_getinfo_url); echo("User Data recieved:", $user_data); //process $user_data as you need....more code here!!! ?>
You can publish to the Facebook graph by issuing HTTP POST requests to the appropriate connection URLs, using an access token.
For example, you can post a new wall post on Arjun's wall by issuing a POST request to https://graph.facebook.com/arjun/feed
in PHP using curl library
curl -F 'access_token=...' \
-F 'message=Hello, Arjun. I like this new API.' \
https://graph.facebook.com/arjun/feed
Most write operations require extended permissions for the active user. See the authentication guide for details on how you can request extended permissions from the user during the authentication step.
