I have an app that when the user goes to the app, searches his feed for specific posts. (I have read_stream). But i needed the app to read their feed whenever I want, like once an hour. How can i read their feed without they are in the app ?

推荐答案

每次用户进入您的应用程序时，您必须在数据库上保存fb_id，并且必须保存扩展令牌.该令牌的有效期为60天，因此，每次用户访问您的应用时，您都应续签该令牌，这种方式不会过期.

Every time the user, enters your app you must save is fb_id on your data_base and you must save the extended token. This token will be valid for 60 days, so everytime the user goes to your app you should renew it, this way won't expire.

我不知道您是否正在使用PHP SDK，但是这是获取Facebook扩展令牌的方法:

I don't know if you're using PHP SDK but here's the way you can get the facebook extended token:

 require_once("facebook.php");

  $config = array();
  $config[‘appId’] = 'YOUR_APP_ID';
  $config[‘secret’] = 'YOUR_APP_SECRET';
  $config[‘fileUpload’] = false; // optional

  $facebook = new Facebook($config);
  $facebook->setExtendedAccessToken();
  $access_token = $facebook->getAccessToken();
  $uid = $facebook->getUser();
  //now that you have the extended token and the user id save it on your database.

现在，下次您要离线阅读用户供稿时，只需从数据库中获取用户ID，然后

Now the next time you want to read the feed of the user offline, just grab the user id from the database and

//the next time you want to read the user feed, just grab the uid from your database and access token and set it
  $facebook->setAccessToken($new_access_token);
