在Facebook画布应用中重定向

Question

Is it possible to do page redirects in canvas app? I was reading facebook's tutorial and I am seeing this:

Note that http://www.example.com/canvas cannot forward to another URL via HTTP redirect responses, for example response code 301, but has to return the response directly.

How is this possible?

Answer 1

What the documentation says with this is that you should not have your first page that loads in the canvas, which is referenced here as http://www.example.com/canvas , send a 301 redirect to some another page. You should render and send first page, or http://www.example.com/canvas , and then, if your situation requires redirects then you may do the same.

Answer 2

虽然初始画布页面无法返回301响应，但是您可以让加载的页面通过javascript进行重定向。
