Facebook后端登录 [英] Facebook backend login

问题描述

我一直在使用相同的代码。我试图使用它，它不会让我连接。前端的JavaScript一个工作，我的应用程序ids和所有匹配。因为我想登录用户我做后端验证（任何理智的人）和在verifyfacebook.php（你看的东西）所有的包括在那里，我验证了FACEBOOK_APP_ID和SECRET都是正确的，他们回声与他们的价值观。

我只是不明白发生了什么！
任何人看到我刚刚失踪的东西？

  try {
 $ facebook = new Facebook（array（
'appId'=> FACEBOOK_APP_ID， 
'secret'=> FACEBOOK_SECRET_ID，
'cookie'=> true，
））; 
 
 $ session = $ facebook-> getSession（）; 
 
 $ fbme = null; 
 
 //基于会话的图API调用。 
 if（$ session）{
 try {
 $ uid = $ facebook-> getUser（）; 
 $ fbme = $ facebook-> api（'/ me'）; 
} catch（FacebookApiException $ f）{
} 
} 
} catch（异常$ e）{
}

我只是试图简单的说明，它仍然无法工作。

  $ facebook = new Facebook（array（
'appId'=> FACEBOOK_APP_ID，
'secret'=> FACEBOOK_SECRET_ID，
'cookies'=> true 
））; 
 
 //获取用户ID 
 $ uid = $ facebook-> getUser（）; 
 
 echo $ uid; 
  

它回显0

解决方案

cookie 参数不再与3.0.x一起使用。以下代码在我删除了所有的cookies之前没有工作，包括会话。 redirect_uri 是可选的，只需确保您重定向到执行代码的同一页。

  $ facebook = new Facebook（array（
'appId'=> FACEBOOK_APP_ID，
'secret'=> FACEBOOK_SECRET_ID，
））; 
 
 $ user = $ facebook-> getUser（）; 
 
 if（$ user）
 {
 echo sprintf（
'< a href =％s>注销< / a>'，
 $ facebook-> getLogoutUrl（array（
'redirect_uri'=> URL，
））
）; 
} 
 else 
 {
 echo sprintf（
'< a href =％s>登录< / a>'，
 $ facebook-> getLoginUrl（array（
'redirect_uri'=> URL，
'scope'=> SCOPE，
））
）; 
} 
 
 if（$ user）
 {
 try 
 {
 print_r（$ facebook-> api（'/ me' ）; 
} 
 catch（FacebookApiException $ e）
 {
 print_r（$ e）; 
} 
} 
  

I have been using this same code for so. I tried to use it and it will not let me connect. The front-end javascript one works and my app ids and all that match. Since i want to log in the user i do back end verification (as any sane person would) and in verifyfacebook.php (the stuff your looking at) all the includes are there and i verified that FACEBOOK_APP_ID and SECRET both are correct and they echo out with their values.

I just do not understand what is going on! Anyone see anything i am just missing?

try {
    $facebook = new Facebook(array(
      'appId'  => FACEBOOK_APP_ID,
      'secret' => FACEBOOK_SECRET_ID,
      'cookie' => true,
    ));

    $session = $facebook->getSession();

    $fbme = null;

    // Session based graph API call.
    if ($session) {
        try {
            $uid = $facebook->getUser();
            $fbme = $facebook->api('/me');
        } catch (FacebookApiException $f) {
        }
    }
} catch (Exception $e) {
}

I just tried to simply the example and it still wont work.

$facebook = new Facebook(array(
  'appId' => FACEBOOK_APP_ID,
  'secret' => FACEBOOK_SECRET_ID,
  'cookies' => true
));

// Get User ID
$uid = $facebook->getUser();

echo $uid;

It echos '0'

解决方案

cookie parameter is no longer used with 3.0.x. Below code did not work until I have removed all cookies, including session ones. redirect_uri is optional, just make sure you get redirected to the same page this code is executed.

$facebook = new Facebook(array(
    'appId' => FACEBOOK_APP_ID,
    'secret' => FACEBOOK_SECRET_ID,
));

$user = $facebook->getUser();

if ( $user )
{
    echo sprintf(
        '<a href="%s">Logout</a>',
         $facebook->getLogoutUrl(array(
            'redirect_uri' => URL,
         ))
    );
}
else
{
    echo sprintf(
        '<a href="%s">Login</a>',
         $facebook->getLoginUrl(array(
            'redirect_uri' => URL,
            'scope'        => SCOPE,
         ))
    );
}

if ( $user )
{
    try
    {
        print_r($facebook->api('/me');
    }
    catch ( FacebookApiException $e )
    {
        print_r($e);
    }
}
