Facebook SDK + CodeIgniter会话 [英] Facebook SDK + CodeIgniter sessions

问题描述

我使用的是CodeIgniter的内置会话类，因此，我不希望Facebook SDK开始自己的会话(通过 session_start()并使用 $ _ SESSION 变量.)

I'm using CodeIgniter's built in session class, and therefore I don't want the Facebook SDK to start it's own session (by session_start() and using the $_SESSION variable).

有什么方法可以防止SDK使用本机会话，如果要如何使用它来代替CodeIgniter会话类?甚至有可能吗?

Is there any way to prevent the SDK from using native sessions and if, how do I make it utilize the CodeIgniter session class instead? Is it even possible?

推荐答案

这很晚了，但以防万一有人遇到相同问题.只需在自定义类中实现PersistentDataHandler，如下所示: https://developers.facebook.com/docs/php/PersistentDataInterface/5.0.0

This is pretty late but just in case someone else runs into the same issue. Just implement the PersistentDataHandler in a custom class as stated here: https://developers.facebook.com/docs/php/PersistentDataInterface/5.0.0

这是我实现的codeigniter版本.(注意:会话库是自动加载的，因此我省略了它的加载.如果您的情况不尽如人意，请尝试加载它)

Here is a codeigniter version I implemented. (NOTE: Session library is autoloaded so I have omitted loading it. If that not your case endeavour to load it)

use Facebook\PersistentData\PersistentDataInterface;

class CIPersistentDataHandler implements PersistentDataInterface
{
    public function __construct()
    {
       $this->ci =& get_instance();
    }
    /**
    * @var string Prefix to use for session variables.
    */
    protected $sessionPrefix = 'FBRLH_';

    /**
    * @inheritdoc
    */
    public function get($key)
    {
        return $this->ci->session->userdata($this->sessionPrefix.$key);
    }

    /**
    * @inheritdoc
    */
    public function set($key, $value)
    {
        $this->ci->session->set_userdata($this->sessionPrefix.$key, $value);
    }
}

然后启用这样的自定义类

Then enable your custom class like this

$fb = new Facebook\Facebook([
  // . . .
  'persistent_data_handler' => new CIPersistentDataHandler(),
  // . . .
  ]);

注意(适用于CODEIGNITER版本3或更低版本)

无论您决定实例化Facebook类，别忘了包括自定义类和Facebook SDK.请参见下面的示例:

Don't forget to include the custom class and Facebook SDK wherever you decide to instatiate the Facebook class. See example below:

require_once APPPATH.'libraries/facebook-php-sdk/autoload.php';
require_once APPPATH.'libraries/CIPersistentDataHandler.php';

use Facebook\Facebook;
use Facebook\Authentication\AccessToken;
use Facebook\Exceptions\FacebookResponseException;
use Facebook\Exceptions\FacebookSDKException;
use Facebook\Helpers\FacebookJavaScriptHelper;
use Facebook\Helpers\FacebookRedirectLoginHelper;

class Facebooklogin {
    ...

    $fb = new Facebook\Facebook([
      // . . .
      'persistent_data_handler' => new CIPersistentDataHandler(),
      // . . .
      ]);
}

我希望这会有所帮助！
