为什么Facebook PHP SDK getUser总是返回0？ [英] Why is Facebook PHP SDK getUser always returning 0?

问题描述

我正在尝试使用需要Facebook用户的一些信息的网站，我正在使用PHP和JS SDK。

I'm trying to work with a website that requires some information from a Facebook user, I'm using PHP and JS SDKs.

我有一个功能PHP：

public function isLoggedOnFacebook() {
    $user = $this->_facebook->getUser();
    if ($user) {
        return $this->_facebook->api("/$user");
    }
    return false;
}

在<$ c中的SDK中保存Facebook对象的类$ c> $ this-> _facebook 。

然后在一个块上我这样做：

Then on a block I do this:

<?php if (!$this->isLoggedOnFacebook()): ?>
<div>
   <fb:login-button show-faces="true" perms="email" width="500" />
</div>
<?php endif ?>

FB JS环境正确设置（我认为），所以它的工作原理。所以用户得到弹出并授权该网站。

And the FB JS environment is properly set up (I think) so it works. So the user gets the pop up and authorizes the site.

问题是甚至在应用程序被用户授权之后，$ user始终为0，意思是 $ facebook-> getUser（）总是返回0，然后列出用户的面孔，包括记录的用户，但如果我调用 $ facebook- &api（'/ me'）或其他任何东西，那么它会抛出无效的令牌异常。

The problem is even after the app is been authorized by the user $user is always 0, meaning $facebook->getUser() always returns 0, and then lists the faces of users, including the logged user, but if I make it call $facebook->api('/me') or whatever, then it'll throw the invalid token exception.

我看到这个问题，但我没有看到一个解决方案，我不知道
哪里的问题是，我用尽了想法。

I've seen this problem, but I haven't seen a solution, I have no idea where the problem is and I run out of ideas.

有一个网站标签开发人员的Facebook页面在应用程序部分，您可以在其中设置您的站点URL和您的站点域，我认为这是我的问题的原因，但我不知道这些字段应该包含什么。

There's a Website tab on the developers' Facebook page in the apps section, where you can set up your Site URL and your Site Domain, and I'm thinking this are the cause of my problem, but I have no knowledge of exactly what these fields are supposed to contain.

推荐答案
