如何在PHP和Zend中使用Facebook Connect注销用户？ [英] How to log out users using Facebook Connect in PHP and Zend?

问题描述

我正在使用PHP和Zend Framework来构建一个Connect应用程序。
我也有一个基于Zend_Auth的用户认证系统。
现在，我可以使用Facebook登录，但注销不起作用。

I am trying to build a Connect app using PHP and the Zend Framework. I also have a Zend_Auth based user authentication system. Now, I am able to log in using Facebook but log out is not working.

我需要清除Zend_Auth身份以及删除所有Facebook登录信息。
最好的方法是什么？

I need to clear the Zend_Auth identity as well as remove all Facebook login info. What would be the best way to do this?

我尝试过 facebook_client-> expire_session（）和 facebook_client-> clear_cookie_state（）; 在一起，还有 facebook_client-> logout（$ next） Zend_Auth :: getInstance（） - > clearIdentity（）

I tried facebook_client->expire_session() and facebook_client->clear_cookie_state(); together and also facebook_client->logout($next) after calling Zend_Auth::getInstance()->clearIdentity()

他们似乎都没有工作。 >

None of them seem to work.

推荐答案

您必须先调用javascript客户端注销，然后将其发送到您的php注销脚本。所以，调用.js：

You have to call the javascript client logout first, then send them to your php logout script. So, call .js:

FB.Connect.logoutAndRedirect("/path/to/zend/logout/controller");

你会看到一个模态的弹出窗口，说你正在注销这个网站和Facebook *你将被重定向到您的注销脚本的任何地方：

You'll see a modal popup that says "you are logging out of this site and facebook* You'll be redirected to wherever your logout script is:

try
{
    $facebook->expire_session();
}
catch (FacebookRestClientException $e)
{
    //you'll want to catch this
    //it fails all the time
}

我通常也会在PHP注销脚本中调用此函数，只是为了安全： / p>

I usually also call this function in the PHP logout script, just to be safe:

/**
 * Remove the local Facebook cookies that get set manually
 * 
 * @return void
 */
protected function _killFacebookCookies()
{
    // get your api key
    $apiKey = $this->getConfig()->getApiKey();
    // get name of the cookie
    $cookie = $this->getConfig()->getCookieName();

    $cookies = array('user', 'session_key', 'expires', 'ss');
    foreach ($cookies as $name) 
    {
        setcookie($apiKey . '_' . $name, false, time() - 3600);
        unset($_COOKIE[$apiKey . '_' . $name]);
    }

    setcookie($apiKey, false, time() - 3600);
    unset($_COOKIE[$apiKey]);       
}
