如何获得通过facebook api查看我朋友的更新的权限?开发维基并没有真正帮助我......我只需要一个代码示例......

您需要为用户提供read_stream扩展权限。 http://developers.facebook.com/docs/authentication/permissions/
如果您在活动的用户会话期间执行此操作(例如,不使用offline_access扩展权限),那么阅读更新将变得非常简单。
示例(使用php):
<?php
require 'facebook.php';
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => 'YOUR APP ID',
'secret' => 'YOUR APP SECRET',
'cookie' => true,
));
try
{
$user_feed = $facebook->api('/me/home/');
/**
* You now have the users's news feed, you can do with it what you want.
* If you want to prune it for friends only...you need to do a little more
* work..
**/
$friend_only_feed = array();
if (!empty($user_feed['data']))
{
$user_feed_pagination = $user_feed['paging'];
$user_feed = $user_feed['data'];
$friends = $facebook->api('/me/friends', 'GET');
$friend_list = array();
if (!empty($friends['data']))
{
$friends = $friends['data'];
foreach ($friends as $friend)
{
$friend_list []= $friend['id'];
}
}
$friend_only_feed = array();
foreach ($user_feed as $story)
{
if (in_array($story['from']['id'], $friend_list))
{
$friend_only_feed []= $story;
}
}
}
}
catch (FacebookApiException $e)
{
/**
* you don't have an active user session or required permissions
* for this user, so rdr to facebook to login.
**/
$loginUrl = $facebook->getLoginUrl(array(
'req_perms' => 'publish_stream'
));
header('Location: ' . $loginUrl);
exit;
}
print_r($friend_only_feed);
这应该包括获取用户的新闻Feed,以及从朋友那里获取所有帖子(不包括网页更新)。如果您没有访问权限,它会将用户重定向到登录状态并为您提供访问权限。
值得注意的是,默认的home
端点只能让您回到过去的25个故事。如果您需要返回更远的地方,Facebook响应中的paging
键可让您执行多个请求以返回更远,或者您可以将数组传递给api()方法告诉Facebook您想要更大的限制
<?php
$user_feed = $facebook->api('/me/home/', 'GET', array(
'limit' => 500
));
