如何获得许可？

我已经创建了一个简单的Facebook应用程序。现在我想获得read_stream的权限。如何获得许可？

我已经阅读了很多文档，但我不明白。

你能告诉我如何获得这个权限与PHP或JavaScript？

编辑：

我已经使用这个源代码（可以SE它的工作here），但不工作，因为我得到的只是基本的权限：

<?php 

require_once('facebook.php'); 

// Create our Application instance (replace this with your appId and secret). 
$facebook = new Facebook(array(
    'appId' => 'xxx', 
    'secret' => 'xxx', 
    'cookie' => true, 
)); 


$session = $facebook->getSession(); 

$me = null; 
// Session based API call. 
if ($session) { 
    try { 
    $uid = $facebook->getUser(); 
    $me = $facebook->api('/me'); 
    } catch (FacebookApiException $e) { 
    error_log($e); 
    } 
} 

// login or logout url will be needed depending on current user state. 

if (!$me) { 
$loginUrl = $facebook->getLoginUrl(); 


} else { 

    // $fbme is valid i.e. user can access our app 
    $logoutUrl = $facebook->getLogoutUrl(); 
} 


// This call will always work since we are fetching public data. 


?>

在的JavaScript API，你可以请求权限在登录期间使用FB.login()。关于它的更多信息here（附带示例）

在PHP中，您可以在身份验证过程中请求扩展权限。关于它的更多信息here（请参阅“请求扩展权限”）

Javascript方法更容易实现。

UPDATE

好有使用FBML fb:login-button标签了权限的第三条道路：

<fb:login-button perms="read_stream,offline_access"></fb:login-button>

请参见上面的...我，如果你使用的登录按钮FBML编辑的问题:) – xRobot 2010-10-14 17:53:16

@xRobot OK，然后有越来越权限的另一种方式（看我的编辑） – serg 2010-10-14 17:59:49

var cb = function(response) { 
       //Log.info('FB.login callback', response); 
    if (response.status === 'connected') { 
    //Log.info('User logged in'); 
    } else { 
    //Log.info('User is logged out'); 
    } 
    }; 
       FB.login(cb, { 
       scope: 'publish_stream', 
       enable_profile_selector: 1 
       });

//服务器端验证

$permissions = $facebook->api("/me/permissions"); 

     if(array_key_exists('publish_stream', $permissions['data'][0])) { 
      $result = $facebook->api($feed_dir, 'post', $msg_body); 
     } 

// result is id of post
