问题描述
我的 Laravel 应用程序默认为每个站点返回 Cache-Control: no-cache, private HTTP 标头.我该如何改变这种行为?
My Laravel application is returning Cache-Control: no-cache, private HTTP header by default for each site. How can I change this behaviour?
P.S.:这不是 PHP.ini 的问题，因为将 session.cache_limiter 更改为 empty/public 不会改变任何东西.
P.S.: It is not a PHP.ini problem, because changing session.cache_limiter to empty/public does not change anything.
推荐答案
Laravel 5.5 <
您可以为此拥有一个全局中间件.类似:
Laravel 5.5 <
You can have a global middleware for that. something like:
<?php
namespace AppHttpMiddleware;
use Closure;
class CacheControl
{
public function handle($request, Closure $next)
{
$response = $next($request);
$response->header('Cache-Control', 'no-cache, must-revalidate');
// Or whatever you want it to be:
// $response->header('Cache-Control', 'max-age=100');
return $response;
}
}
然后将其注册为内核文件中的全局中间件:
then just register this as a global middleware in the Kernel file:
protected $middleware = [
....
AppHttpMiddlewareCacheControl::class
];
