PHP Twitter OAuth - 我无法验证我的帐户

我整天都在努力实现Twitter身份验证（使用OAuth），但我已经绝望了，我仍然收到错误消息无法验证您的身份，这正在成为我的噩梦。

以下是我用于身份验证的两个文件：

请求奥特.php

session_start();
$basedir=dirname(__FILE__)."";  
include($basedir.'/config.php');
include_once( $basedir.'/twitteroauth/twitteroauth.php' );
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET);    
$request_token = $connection->getRequestToken(OAUTH_CALLBACK);
//$_SESSION['oauth_token'] = $token = $request_token['oauth_token'];
//$_SESSION['oauth_token_secret'] = $secret = $request_token['oauth_token_secret'];
$_SESSION['oauth_token'] = $request_token['oauth_token'];
$_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret']; 
switch ($connection->http_code) {
  case 200:
    $url = $connection->getAuthorizeURL($_SESSION['oauth_token'], FALSE);
    header('Location: ' . $url); 
    break;
  default:
    echo 'Could not connect to Twitter. Refresh the page or try again later.';
}

索引.php

if(!isset($_GET['oauth_verifier'])){
    $link_redirect = '<a href="requestOauth.php">Login With Twitter</a>';
}
else
{
    if(isset($_SESSION['access_token'])){ 
        $oauth_token = $_SESSION['access_token']['oauth_token'];
        $oauth_token_secret = $_SESSION['access_token']['oauth_token_secret'];
        $twitterRequest = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $oauth_token, $oauth_token_secret);
    } else {
        $twitterRequest = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $_SESSION['oauth_token'], $_SESSION['oauth_token_secret']);
        $accessToken = $twitterRequest->getAccessToken($_GET['oauth_verifier']);
        $_SESSION['access_token'] = $accessToken;
        echo 'ACCESS TOKEN2: '.var_dump($_SESSION['access_token']);
    }
    $user_info = $twitterRequest->get('account/verify_credentials');
    if(isset($user_info->error))
    {
        echo $user_info->error;
        //header("location: requestOauth.php");
    }  else {
        var_dump($_GET);
    }

我仍然收到错误 无法验证您的身份。 并且已经不知道，哪里可能出了问题...

你能给我任何帮助吗，如何解决这个问题？

谢谢
