推荐答案
对应用程序的页面标签URL"(通过页面"标签加载应用程序时使用的URL)的每个请求都将包含signed_request参数.
Each request made to your app's 'page tab url' (the URL used when the app is loaded via a Page tab) will include a signed_request parameter.
在 https://developers.facebook.com/docs中解释了对此进行解码的方法/authentication/signed_request/-当您的应用程序加载到页面标签上时，您将始终获得page参数(如果当前用户未授权您的应用程序，则其他参数可能不会显示)大多数页面标签应用都是如此)
The method to decode this is explained at https://developers.facebook.com/docs/authentication/signed_request/ - when your app is loaded on a page tab you'll always get the page parameter (the other parameters may not be present if the current user hasn't authorised your app, which will be the case for most page tab apps)
page参数包括其加载页面的页面ID.然后，您在代码中使用if语句，如果请求来自您不希望安装该应用程序的Page，则决定不显示任何内容(或某些常规内容).
The page parameter includes the Page ID of the Page it's loaded on. You then use an if statement in your code and decide to show nothing (or some generic content) if the request came via a Page you weren't expecting the App to be installed on.
