如何从Facebook应用程序访问用户信息 [英] how to access user information from facebook application

问题描述

请给我一些想法，即使我已经创建了一个在Facebook上注册的应用程序，通过Facebook应用程序访问用户的信息，允许用户添加该应用程序，以便我们可以通过注册的应用程序访问用户的信息。
请尽快回复我

解决方案

这将取决于您要查找的信息量用户。您可以使用signed_request对象获取已登录的用户：

 列表（$ encoded_sig，$ payload）= explode '，$ signed_request，2）; 
 $ data = json_decode（base64_url_decode（$ payload），true）; 
  

从数据获取用户

  $ user = $ data-> user; 
  

一旦您拥有验证和登录的用户，您可以使用图形API来获取您的只要您已经正确设置了您的权限，就想要使用者：

  $ user_profile = $ facebook-> api '/我'， 'GET'）; //与$ facebook是您的身份验证的FB对象
  

$ user_profile将具有关于此链接上列出的用户：
FB用户对象

让我知道这是你正在问的。以上信息是基于PHP程序，您也可以使用FBJS代码执行大部分操作。

解决方案

That's going to depend on how much information you're looking to get about the user. You can use the signed_request object to get the user that's signed in:

 list($encoded_sig, $payload) = explode('.', $signed_request, 2); 
 $data = json_decode(base64_url_decode($payload), true);

And from the data get the user

$user = $data->user;

Once you have a verified and logged in user, you can use the graph API to get back what you want about the user as long as you've set up your permissions correctly:

    $user_profile = $facebook->api('/me','GET');  //  with $facebook being your authenticated FB object  

The $user_profile will have all of the information about the user that's listed on this link: FB User Object

Let me know if that's what you were asking about. The above information is based on a PHP program, you can do most of that with the FBJS code as well.
