1、生成中介軟體

[root@localhost MRedis]# php artisan make:middleware CheckLogin
Middleware created successfully.

2、實現中介軟體，在app\http\middleware\CheckLogin.php

public function handle($request, Closure $next)
    {
        if (!session('user')) {
            return redirect('login');
        }
        return
 
 $next($request);
    }

3、註冊中介軟體，在app\http\kernel.php下，新增的為最後一行

protected $routeMiddleware = [
        'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'bindings' => \Illuminate\Routing
 
\Middleware\SubstituteBindings::class,
        'can' => \Illuminate\Auth\Middleware\Authorize::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'check.login' => \App\Http\Middleware
 
\CheckLogin::class,   // 這一行
    ];

4、使用中介軟體（一定要把登入路由的放在外面）

Route::group(['middleware' => 'check.login'], function() {內部為，不想讓未登入使用者進的路由}

5、成功
