How to use the OAuth Class in codeigniter? - php

Question

I'm trying to add the OAuth class in codeigniter but when i call it's show error
Non-existent class: OAuth
This is my code
class Food extends My_Controller
{
public function __construct(){
$this->load->library('OAuth');
}
public function get_yelp_api(){
$unsigned_url = "http://api.yelp.com/v2/business/the-waterboy-sacramento";
$consumer_key = '***********';
$consumer_secret = '**********';
$token = '***************';
$token_secret = '**************';
$token = new OAuthToken($token, $token_secret);
$consumer = new OAuthConsumer($consumer_key, $consumer_secret);
$signature_method = new OAuthSignatureMethod_HMAC_SHA1();
$oauthrequest = OAuthRequest::from_consumer_and_token($consumer, $token, 'GET', $unsigned_url);
$oauthrequest->sign_request($signature_method, $consumer, $token);
$signed_url = $oauthrequest->to_url();
$ch = curl_init($signed_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
$data = curl_exec($ch);
curl_close($ch);
$response = json_decode($data);
$json_string = file_get_contents($signed_url);
$result = json_decode($json_string);
echo '<pre>';
print_r($result);
echo '</pre>';
}
}
I also try to add it on this way
require_once(APPPATH.'libraries/OAuth.php');
but still got an error
Non-existent class: OAuth

Answer 1

you doing mistake loading a class as library load it like this
Non-existent class:OAuth
solution
just only need to load class at the top of controller like this:
require_once(APPPATH.'libraries/OAuth.php');
