Post on a wall using Facebook graph - facebook

Question

I am trying to post on a wall using an http post request with the given url but I'm getting a method not implemented error. What am I doing wrong?
Assuming the user has already authorized my app and I have an access token with publish_stream permissions, is it possible to create a URL that will post to the users wall using the facebook graph?
Here is the url I am using where [userid] is the user id and [access_Token] is the access token:
https://graph.facebook.com/[userid]/feed?message=I like Cheesy Poofs&picture=http://simplyrecipes.com/photos/cheddar-cheese-puffs-b.jpg&link=alink.com&name=Cheesy Poofs Rule!&caption=Some awesome caption&description=cool description bruh&access_token=[access_token]
Edit
In the link above I was missing "method=post". I now get an ID back from the following URL.
https://graph.facebook.com/[userid]/feed?method=post&message=I like Cheesy Poofs&picture=http://simplyrecipes.com/photos/cheddar-cheese-puffs-b.jpg&link=alink.com&name=Cheesy Poofs Rule!&caption=Some awesome caption&description=cool description bruh&access_token=[access_token]

Answer 1

You should be using post, like:
$update = $facebook->api('/[userid]/feed', 'post',
array('message'=> 'your message here',
'picture' => 'your picture link',
'link' => 'your link here'));

Sample using php icm signed request:
<?php
$signedRequestObject = parse_signed_request( $_POST["signed_request"],YOUR_APPLICATION_SECRET );
if ($signedRequestObject["oauth_token"]){
// there is no token, something went wrong
exit;
}
$token = $signedRequestObject["oauth_token"];
$data = array(
"message" => "happy joy joy message",
"link" => "www.myjoyfullsite.com",
"access_token" => $token,
"picture" => "www.myjoyfullsite.com/avatar.jpg",
"name"=> "funky title",
"caption"=> "awesome caption",
"description"=> "useful description"
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://graph.facebook.com/".$id."/feed");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$op = curl_exec($ch);
if (!$op){
echo "Curl Error : ".curl_error($ch);
curl_close($ch);
exit;
}
curl_close($ch);
$res = get_object_vars(json_decode((string)$op));
print_r($res);
//used functions
function parse_signed_request($signed_request, $secret) {
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$sig = $this->base64_url_decode($encoded_sig);
$data = json_decode($this->base64_url_decode($payload), true);
if (strtoupper($data['algorithm']) !== 'HMAC-SHA256') {
echo 'Unknown algorithm. Expected HMAC-SHA256 : ';
return false;
}
$expected_sig = hash_hmac('sha256', $payload, $secret, $raw = true);
if ($sig !== $expected_sig) {
echo = 'Bad Signed JSON signature!';
return false;
}
return $data;
}
function base64_url_decode($input) {
return base64_decode(strtr($input, '-_', '+/'));
}
?>
Sample JS:
var body = 'Reading JS SDK documentation';
FB.api('/me/feed', 'post', { message: body }, function(response) {
if (!response || response.error) {
alert('Error occured');
} else {
alert('Post ID: ' + response.id);
}
});
Hope it helps!
Cheers!
