Laravel 5.4获取引荐 [英] Laravel 5.4 get Referer

问题描述

我正在尝试获取用户的引荐来源.就像他们来自Facebook，YouTube，Google或其他任何网站一样.

I'm trying to get the Referer of my users. Like if they come from facebook, youtube, google or anything else.

现在我已经尝试过类似的事情:

Now I've tried something like that:

        $referrer = $this->request->headers->get('referer');
        $url = $referrer ? $this->to($referrer) : $this->getPreviousUrlFromSession();
        return $url ?: $this->to('/'); // returns: Method referer does not exist.

此:

        return $_SERVER["HTTP_REFERER"] // returns Undefined index: HTTP_REFERER

那个:

session_start();

if ( !isset( $_SESSION["origURL"] ) )
    $_SESSION["origURL"] = $_SERVER["HTTP_REFERER"]; // returns Undefined index: HTTP_REFERER

但是没有什么能像预期的那样工作.

But nothing worked like expected.

有人知道我可以检查引荐来源网址的解决方案吗?

Does someone know a solution how I can check the referer?

我需要这样做，因为我想检查用户是否来自某些特定的URL，如果是，我想给用户一些额外的点击"来进行排名.类似于小型会员制.

I need that because I want to check if the user comes from some specific URL's and if so, I want to give the user some extra "clicks" to rank up. Something like a small affiliate system.

推荐答案

看来这将满足您的需求:

It seems like this will do what you are looking for :

Request::server('HTTP_REFERER').

您可以在此处阅读Api DOC:
