Laravel重定向，没有缓存标头

Question

I'm using Laravel 3 and it's not obvious how to set headers in any way other than through Response::make().

I am doing a redirect like this:

return Redirect::to('admin/check');

I'd like to set an additional no-cache header for the redirect like so:

"Cache-Control: no-store, no-cache, must-revalidate"

I realize I could just do this directly in PHP, but is there any way to set response headers via Laravel?

Answer 1

When you call Redirect::to() Laravel instantiates a Response object with 302 status and a Location header. That Response object is then returned by the controller and rendered as a proper HTTP response, so, at controller time, you can still change its headers.

To be even more precise class Redirect extends Response. Take a look here You can achieve that by simply using:

return Redirect::to('admin/check')
    ->header('Cache-Control', 'no-store, no-cache, must-revalidate');
