Twitter API - 在会话中保存 OAuth 令牌

Question

我正在尝试找到一种方法来在使用 OAuth 获得授权后与 Twitter API 保持连接，但我遇到了问题。

我在尝试使用会话或数据库中保存的 Oauth 令牌连接到 Twitter API 时收到 "Invalid / expired Token"。

有没有办法做到这一点？我不希望我的应用程序的用户每次都必须通过 Twitter 登录。当然，一旦他们授权了我的应用程序一次，就足够了？

$consumer_key = 'consumerkey';
$consumer_secret = 'consumersecret';

$twitterObj = new EpiTwitter($consumer_key, $consumer_secret);

if (isset($_GET['oauth_token'])){
    $oauth_token = $_GET['oauth_token'];
} else if ($_SESSION['oauth_token']){
    $oauth_token = $_SESSION['oauth_token'];

    echo $_SESSION['oauth_token'];
} else {
    //see if authorisation already set up in DB
    $query = mysql_query("SELECT oauth_token FROM PingSocialMediaUsers WHERE oauth_provider = 'twitter' AND clientID = '$clientID'");  
    $result = mysql_fetch_row($query); 
    $oauth_token = $result[0];
}

if($oauth_token == ''){ 
    $url = $twitterObj->getAuthorizationUrl();
    $twitter_login = $url;
 } else {
    $twitterObj->setToken($oauth_token);
    $token = $twitterObj->getAccessToken();
    $twitterObj->setToken($token->oauth_token, $token->oauth_token_secret);     
    $_SESSION['oauth_token'] = $token->oauth_token;
    $_SESSION['oauth_secret'] = $token->oauth_token_secret;
    $twitterInfo= $twitterObj->get_accountVerify_credentials();
    $twitterInfo->response;

    echo $twitterInfo->response['error'];
    //echo '<pre>';
    //print_r($twitterInfo);
    $id = $twitterInfo->id;
    $username = $twitterInfo->screen_name;

    //add to details database
    //find the user by ID  
    if ($id != ''){
        $query = mysql_query("SELECT * FROM PingSocialMediaUsers WHERE oauth_provider = 'twitter' AND oauth_uid = '$id'");  
        $result = mysql_fetch_array($query);  

        // If does not exist add to database  
        if(empty($result)){  
            $query = mysql_query("INSERT INTO PingSocialMediaUsers (oauth_provider, oauth_uid, username, oauth_token, oauth_secret) VALUES ('twitter', {$id}, '{$username}', '{$_SESSION['oauth_token']}', '{$_SESSION['oauth_secret']}')"); 
            $query = mysql_query("SELECT * FROM PingSocialMediaUsers WHERE id = " . mysql_insert_id());  
            $result = mysql_fetch_array($query);  
        } else {  
            //update the tokens  
            $query = mysql_query("UPDATE PingSocialMediaUsers SET oauth_token = '{$_SESSION['oauth_token']}', oauth_secret = '{$_SESSION['oauth_secret']}' WHERE oauth_provider = 'twitter' AND oauth_uid = {$id}");  
        }   

        $_SESSION['id'] = $result['id']; 
        $_SESSION['username'] = $result['username']; 
        $_SESSION['oauth_uid'] = $result['oauth_uid']; 
        $_SESSION['oauth_provider'] = $result['oauth_provider']; 
        $_SESSION['oauth_token'] = $result['oauth_token']; 
        $_SESSION['oauth_secret'] = $result['oauth_secret'];    
    }

    $twitterAuth = TRUE;    
}

我相信您在谈论 access_token，您将从 twitter 获得，作为 OAuth 握手的最后一部分，之后您可以代表用户访问那里的服务。

这是他们在官方开发者页面上所说的话

We do not currently expire access tokens. 
Your access token will be invalid if a user explicitly 
rejects your application from their settings or if a Twitter admin suspends 
your application. If your application is suspended there will be
a note on your application page saying that it has been suspended.

因此，您可以很好地将该令牌存储在您的数据库中，并随时可以在以后使用。

这里是 API 页面的参考 Twitter OAuth FAQ

所以我建议您确保您没有更改任何应用程序设置并且您从会话/数据库中获得了有效的 access_token
