Twitter OAuth: There is no request token for this page

4 Views

I’m using Abraham’s TwitterOAuth library to implement Twitter OAuth in my application. However, on clicking the Login button, users are sometimes redirected to the following page:

I said ‘sometimes’, because sometimes the Twitter OAuth provider does generate the request token, and the users are taken to the ‘Grant Permission’ page.

Is this a library issue? Or is this an issue with the Twitter OAuth provider? If there was an issue with my code, then this page should appear every time a user tries to login using his/her Twitter account, and not at random tries.

Here’s the code of the template that the users are redirected to after clicking the Login button: 

<?php

/*
 *Template Name: OAuth

*/

?>

<pre>

<?php

    session_start();
    require "twitteroauth/autoload.php";
    use AbrahamTwitterOAuthTwitterOAuth;

    define('CONSUMER_KEY', "XXXXXXXXXXXXXXX");
    define('CONSUMER_SECRET', "XXXXXXXXXXXXXXXXXXXX");
    define('OAUTH_CALLBACK', "http://localhost/wordpress/index.php/callback/");

    $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET);
    $request_token = $connection->oauth('oauth/request_token', array('oauth_callback' => OAUTH_CALLBACK));
    $_SESSION['oauth_token'] = $request_token['oauth_token'];
    $_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret'];

    $url = $connection->url('oauth/authorize', array('oauth_token' => $request_token['oauth_token']));

    header('Location: '.$url);
?>

</pre>

PS: I also tried regenerating the Consumer Key and Consumer Secret, but that doesn’t seem to have solved the problem.

  1. The two scenarios that seem most likely to me are:

    1) There is an error while getting the request token. Try adding some error handling.

    $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET);
$request_token = $connection->oauth('oauth/request_token', array('oauth_callback' => OAUTH_CALLBACK));
if ($connection->getLastHttpCode() == 200) {
    $_SESSION['oauth_token'] = $request_token['oauth_token'];
    $_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret'];
    $url = $connection->url('oauth/authorize', array('oauth_token' => $request_token['oauth_token']));
    header('Location: '.$url);
} else {
    var_dump($request_token);
    exit('Error getting request_token');
}

    2) Twitter has a bug where it’s not recognizing the the request_token for some reason.

    The next step in debugging is to find out the status of $request_token that results in the error.
