Twitter OAuth - Invalid/Expired Token

twitter_login

        $twitteroauth = new TwitterOAuth($this->__t开发者_Python百科witterKey, $this->__twitterSecret);

        $request_token = $twitteroauth->getRequestToken(Router::url(array('action' => 'twitter', 'authorize'), true));
        $this->Session->write('Twitter', $request_token);

        if($twitteroauth->http_code==200){
            // Let's generate the URL and redirect
            $url = $twitteroauth->getAuthorizeURL($request_token['oauth_token']);
            header('Location: '. $url);
        } else {
            $this->Session->setFlash('Something went wrong');
        }

twitter_callback

    $data['oauth_verifier'] = $_GET['oauth_verifier'];
    $data['oauth_token'] = $this->Session->read('Twitter.oauth_token');
    $data['oauth_token_secret'] = $this->Session->read('Twitter.oauth_token_secret');

    $twitteroauth = new TwitterOAuth($this->__twitterKey, $this->__twitterSecret, $data['oauth_token'], $data['oauth_token_secret']);

    $access_token = $twitteroauth->getAccessToken($data['oauth_verifier']);

When i do a var_dump

i get the following

Array
(
    [ "1.0" encoding="UTF-8"?>

)

Try ksorting just before $twitteroauth = new TwitterOAuth(...) Most of the times, OAuth problems occur because of the requirements of the protocol.

$data['oauth_token_secret'] = $this->Session->read('Twitter.oauth_token_secret');

ksort($data);

$twitteroauth = new TwitterOAuth($this->__twitterKey, $this->__twitterSecret,

Here is a link explaining the normalization (sorting) of the parameters http://oauth.net/core/1.0/#anchor14

Try to increase OAuth oauth_timestamp by a couple of hours.

In PHP OAuth client it looks like this:

private static function generate_timestamp() {
    return time()+5*3600;
}
