如何使用带有默认缓存驱动程序的laravel 9忘记多个缓存密钥

Question

我有这个控制器，它有许多功能和缓存键，取决于用户名.

我需要当更新信息和删除特定用户的所有缓存密钥？有什么办法吗？

我的控制器从缓存中获取数据：

class HomeController extends Controller
{
    private $cache_duration = 60*60*72;

    function home($uname) {
        $info =  Cache::remember('get-all-info-home'.$uname, $this->cache_duration, function() use($uname){
            $user = User::where('name', '=', $uname)->firstOrFail();
            return $user !=null ? $user->about : null;
        });
        return view('home', compact('info'));
    }


    function info($uname) {

        $info =  Cache::remember('get-all-info'.$uname, $this->cache_duration, function() use($uname){
            $user = User::where('name', '=', $uname)->firstOrFail();
            return $user !=null ? $user->about : null;
        });
        return view('info', compact(['info']));
    }

    function skills($uname) {
        $info =  Cache::remember('get-all-user-skills'.$uname, $this->cache_duration, function() use($uname){
            $user = User::where('name', '=', $uname)->firstOrFail();
            return $user !=null ? $user->about : null;
        });
        $skills =   Cache::remember('get-all-skills'.$uname, $this->cache_duration, function() use($uname){
            $user = User::where('name', '=', $uname)->firstOrFail();
            return $user !=null ? $user->skills : null;
        });

        return view('skills', compact(['skills', 'info']));
    }

我试过这样做，但仍然没有用：

$uname = $info->user->name;
  $keys = ['get-all-info-home', 'get-all-info', 'get-all-user-skills',
             'get-all-skills', 'get-all-user-users-education-experiences', 'get-all-education',
             'get-all-experiences', 'get-all-user-users-user-achievements', 'get-all-user-users-achievements',
            'get-all-user-users-user-services', 'get-all-user-users-services-unique',
             'get-all-user-users-user-services'];
             foreach($keys as $key) {
                $key = $key.$uname;
                Cache::forget($key);
             }

类似于lagbox提到的内容，更改为memcache或redis驱动程序，以支持标记，并添加

Cache::

to

Cache::tags('user.....

在您的控制器方法中：

    function home($uname) {
        $info =  Cache::tags('user'.$uname)
            ->remember('get-all-info-home'.$uname, $this->cache_duration, function() use($uname){
            $user = User::where('name', '=', $uname)->firstOrFail();
            return $user !=null ? $user->about : null;
        });
        return view('home', compact('info'));
    }

    function info($uname) {

        $info =  Cache::tags('user'.$uname)
->remember('get-all-info'.$uname, $this->cache_duration, function() use($uname){
            $user = User::where('name', '=', $uname)->firstOrFail();
            return $user !=null ? $user->about : null;
        });
        return view('info', compact(['info']));
    }

then for the cache tag clear you would do:

Cache::tags('user'.$info->user->name)->flush()

如果添加标记由于任何原因不可行，请尝试检查并确保$key.uname实际上正在返回您期望的数据。

            foreach($keys as $key) {
                $key = $key.$uname; // <- maybe this is not returning the right data
                dd($key);  // echo this out just to see if it is
                Cache::forget($key);
             }
