无法在php中设置Cookie

-1

我正在使用社交登录。我试过login with facebook。一旦用户通过身份验证，我可以获得他们的价值，我需要在Cookie中设置他们的ID，以便我可以在网站上创建会话。无法在php中设置Cookie

这里是我的代码，

<?php 
/* 
* login_with_facebook.php 
* 
* @(#) $Id: login_with_facebook.php,v 1.2 2012/10/05 09:22:40 mlemos Exp $ 
* 
*/ 
    require('http.php'); 
    require('oauth_client.php'); 

    $client = new oauth_client_class; 
    $client->server = 'Facebook'; 
    $client->redirect_uri = 'http://'.$_SERVER['HTTP_HOST']. 
     dirname(strtok($_SERVER['REQUEST_URI'],'?')).'/login_with_facebook.php'; 

    $client->client_id = ''; $application_line = __LINE__; 
    $client->client_secret = ''; 

    if(strlen($client->client_id) == 0 
    || strlen($client->client_secret) == 0) 
     die('Please go to Facebook Apps page https://developers.facebook.com/apps , '. 
      'create an application, and in the line '.$application_line. 
      ' set the client_id to App ID/API Key and client_secret with App Secret'); 

    /* API permissions 
    */ 
    $client->scope = 'email'; 
    if(($success = $client->Initialize())) 
    { 
     if(($success = $client->Process())) 
     { 
      if(strlen($client->access_token)) 
      { 
       $success = $client->CallAPI(
        'https://graph.facebook.com/me', 
        'GET', array(), array('FailOnAccessError'=>true), $user); 
      } 
     } 
     $success = $client->Finalize($success); 
    } 
    if($client->exit) 
     exit; 
    if($success) 
    { 
?> 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
<head> 
<title>Facebook OAuth client results</title> 
</head> 
<body> 
<?php 

echo "This is id i got from facebook ".$user->id." I am unable to set this value in cookie."; 

mysql_connect('localhost', 'user_id', 'pwd'); 
mysql_select_db("DB Name");  

$sql = "INSERT INTO oauth SET auth_id = ".$user->id.", 
            name  = '".$user->name."', 
            email = '".$user->email."', 
            link  = '".$user->link."'"; 
mysql_query($sql); 

if(isset($_COOKIE['auth_id'])) 
    unset($_COOKIE['auth_id']); 

setcookie("auth_id", $user->id, time()+60*60*24, "/"); 
?> 

<script> 
//window.close(); 
</script> 
</body> 
</html> 
<?php 
    } 
    else 
    { 
?> 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
<head> 
<title>OAuth client error</title> 
</head> 
<body> 
<h1>OAuth client error</h1> 
<pre>Error: <?php echo HtmlSpecialChars($client->error); ?></pre> 
</body> 
</html> 
<?php 
    } 
?>

只是设置cookie更新我的域名之后。但这不适合我。

你确定用户ID是否设置？ – 2013-05-08 11:37:47

这可能是您的cookie只有在下一页刷新后才可用。 – egig 2013-05-08 11:38:02

你如何测试cookie的设置？ – Luceos 2013-05-08 11:39:16

从php.net网站：Like other headers, cookies must be sent before any output from your script (this is a protocol restriction).（http://www.php.net/manual/en/function.setcookie.php）。

如果您已经开始输出，则无法设置cookie。因此，您需要将setcookie代码放在第一个HTML的上方。
