Laravel sending no-cache header
提问by Kristoffer Svanmark
I'm having trouble with Laravel 4. Somehow the header
我在使用 Laravel 4 时遇到问题。不知何故标题
Cache-Control: no-cache
Is always being sent in the response on all pages within my site. I can't find where or how to change it.
总是在我网站内所有页面的响应中发送。我找不到在哪里或如何更改它。
Since this is affecting all my controllers where I'm presenting a view with View::MakeI would really like a way to change this globally.
由于这会影响我在其中展示视图的所有控制器，因此我View::Make真的很想要一种方法来全局更改它。

If you want to use Cache, you can change its behavior in your "Response" object (returned by a controller method in this example) :
如果你想使用缓存，你可以在你的“响应”对象中改变它的行为（在这个例子中由控制器方法返回）：
public function myControllerMethod() {
$response = Response::make('something');
$response->setLastModified(new DateTime("now"));
$response->setExpires(new DateTime("tomorrow"));
return $response;
}
It works in my environnement, I hope it will help.
它适用于我的环境，我希望它会有所帮助。
EDIT:
编辑：
If you want to set it globally, you can try this (in app/start/directory):
如果你想全局设置它，你可以试试这个（在app/start/目录中）：
App::after(function($request, $response) {
$response->setLastModified(new DateTime("now"));
$response->setExpires(new DateTime("tomorrow"));
});

To help someone else trying to find the answer for Laravel 5.4, this would be:
为了帮助其他人试图找到 Laravel 5.4 的答案，这将是：
namespace App\Http\Controllers;
use DateTime;
class MyController extends Controller
{
public function index()
{
return response('my content here')
->setLastModified(new DateTime("now"))
->setExpires(new DateTime("tomorrow"));
}
}
