如何在PHP和Zend中使用Facebook Connect注销用户?

您必须调用javascript客户端注销 ,然后将它们发送到php注销脚本。因此,调用.js:

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

您将看到一个模式弹出窗口,显示“您正在注销此网站和facebook*您将被重定向到您的注销脚本所在的位置:

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

为了安全起见,我通常在PHP注销脚本中调用此函数:

/**
 * 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]);       
}

您可以使用如下PHP代码注销facebook用户并将用户重定向到您的网站页面:

标题(“位置:”.$facebook->getLogoutUrl(数组('next'=>)http://yourwebsite.com/redirectAfterFacebookLogout.php")));

(新FACEBOOK SDK) 对我来说getconfig()不起作用,所以我必须从base_facebook.php文件中找到新函数,并在其中添加这段代码。

 public function _killFacebookCookies() 
    { 
        // get your api key 
        $apiKey = $this->getAppId();
        // get name of the cookie 
        $cookie = $this->getSignedRequestCookieName();

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

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