No, since facebook "proxies" every request to your app, you will never see a referer. 不可以，因为facebook“代理”了对您应用的每个请求，所以您将永远不会看到引荐来源。 The only thing you could do would be handing out self generated referer-urls. 您唯一可以做的就是分发自己生成的Referr-URL。
Just apply the GET parameter app_data to your url - this gets passed directly through to your app with the signed request. 只需将GET参数app_data应用于您的网址-随签名请求直接传递给您的应用。 This would be a method of tracking how many visitors come from sources you know and made a link deal, for example. 例如，这将是一种跟踪来自您知道的来源并进行链接交易的访客数量的方法。
