Question

我创建了一个简单的facebook应用程序。现在我想获得read_stream的许可。

我已经阅读了很多文档，但我不明白。

你能告诉我如何使用PHP或javascript获得此权限吗？

编辑：

我已经使用过这个源代码（你可以使用它here）但是没有用，因为我只获得了基本权限：

<?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.

FB.login(function(response) {

      // user is logged in and granted some permissions.
      // perms is a comma separated list of granted permissions

      // user is logged in, but did not grant any permissions
    }
  } else {
    // user is not logged in
  }
}, {perms:'read_stream'});


        // whenever the user logs in, we refresh the page
        FB.Event.subscribe('auth.login', function() {

Answer 1

   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

Answer 2

在javascript API中，您可以使用FB.login()在登录期间请求权限。更多关于它here（附例子）

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（参见“请求扩展权限”）

Javascript方法更容易imo。

好的，第三种方法是使用fb:login-button fbml标记获取权限：

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

如何获得许可？
