使用中间件进行后台权限验证

创建中间件

php artisan make:middleware AdminMiddleware

执行后会在app/Http/Middleware目录下生成AdminMiddleware.php文件

在AdminMiddleware类handle方法中使用Auth验证

use Auth;

public function handle($request, Closure $next)
 {
        if(!Auth::guard('admin')->check()){
            return redirect('/admin/login');
        }
        return $next($request);
 }

路由中挂载此中间件

配置app/Http/Kernel.php

protected $routeMiddleware = [
        'admin.auth' => AdminMiddleware::class,      //在路由中挂载登录验证中间件
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
        'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
        'can' => \Illuminate\Auth\Middleware\Authorize::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'signed' => \Illuminate\Routing\Middleware\ValidateSignature::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'verified' => \Illuminate\Auth\Middleware\EnsureEmailIsVerified::class,
    ];

在控制器中使用登录验证中间件

public function __construct()
 {
        //登录验证中间件
        $this->middleware('admin.auth')->except(['loginForm','login']);
 }

except() 排除loginForm、login方法

Auth&guard完成退出功能

退出方法

 public function logout()
 {
    Auth::guard('admin')->logout();
    return redirect('/admin/login');
 }
