Facebook邀请画布，如何从邀请URL获取PageID

Question

I'm using Facebook Requests ( https://developers.facebook.com/docs/games/requests/ ) to invite people from my Page Tab App to my Page Tab App. I needed to create a canvas that this works. Now I want to redirect the people, who click on the Invite and land on my Canvas URL, to my page tab url. But I need to fetch the pageID, to redirect them.

Can I do a signed-request in my canvas and fetch the PageID from the users invite request? If yes, how?

我很确定请求仅适用于画布游戏。
