[PHP知识库]Lavavel实现登录跳转功能

前言

登录跳转：
不同的用户在登录成功之后跳转到不同的网页当中

例如：网站管理员登录成功后跳转到网站后台，vip用户登录成功后跳转到vip页面

准备工作

用户表

CREATE TABLE `users` (
  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,
  `email` varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,
  `role` varchar(40) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT 'normal',
  `email_verified_at` timestamp NULL DEFAULT NULL,
  `password` varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,
  `remember_token` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `created_at` timestamp NULL DEFAULT NULL,
  `updated_at` timestamp NULL DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `users_email_unique` (`email`),
  KEY `users_role_index` (`role`)
) ENGINE=MyISAM AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

分别录入系统管理员、vip用户和普通用户

使用redirectPath和middeware实现安全的登录跳转

1）app\Http\Controllers\Auth\LoginController.php下复写redirectPath方法
判断登录的用户，实现不同的跳转页

//复写redirectPath实现登录跳转
    public function redirectPath()
    {
        switch (auth()->user()->role) {
            case 'admin':
                return 'admin/dashboard';
            case 'vip':
                return 'vip/dashboard';
            default:
                return '/home';
        }
    }

2）创建Isvip和Isadmin中间件过滤越权访问用户

php artisan make:middleware Isvip
php artisan make:middleware Isadmin

Isvip

public function handle($request, Closure $next)
    {
        //如果是vip则往下执行逻辑
        if(auth()->user()->role === 'vip'){
            return $next($request);
        }
        //不是vip则跳转到首页
        return redirect('/home');
    }

Isadmin

public function handle($request, Closure $next)
    {
        //如果是管理员则往下执行逻辑
        if(auth()->user()->role === 'admin'){
            return $next($request);
        }
        //不是管理员则跳转到首页
        return redirect('/home');
    }

app\Http\Kernel.php注册Isadmin和Isvip中间件

protected $routeMiddleware = [
\Illuminate\Auth\Middleware\EnsureEmailIsVerified::class,
        'admin' => \App\Http\Middleware\Isadmin::class,
        'vip' => \App\Http\Middleware\Isvip::class,
    ];

路由中加入中间件进行访问过滤

//中间件检查访问该目录admin/dashboard是否为admin用户，过滤不合格的用户
Route::get('admin/dashboard', function (){
    return view('admin.dashboard');
})->middleware(['auth','admin']);

//中间件检查访问该目录vip/dashboard是否为vip用户，过滤不合格的用户
Route::get('vip/dashboard', function (){
    return view('vip.dashboard');
})->middleware(['auth','vip']);

优化在不使用复写redirectPath方法下实现登录跳转

创建UserRoleRedirect中间件用于不同用户登录跳转不同页面功能实现

 php artisan make:middleware UserRoleRedirect

UserRoleRedirect逻辑代码

public function handle($request, Closure $next)
    {
        switch (auth()->user()->role) {
            case 'admin':
                return redirect('admin/dashboard');
            case 'vip':
                return redirect('vip/dashboard');
            default:

                break;
        }

        return $next($request);
    }

路由使用结合admin和vip中间件过滤

Route::get('/home', function () {
    return view('welcome');
})->middleware(['auth','auth.redirect']);

Auth::routes();

//中间件检查访问该目录admin/dashboard是否为admin用户，过滤不合格的用户
Route::get('admin/dashboard', function (){
    return view('admin.dashboard');
})->middleware(['auth','admin']);

//中间件检查访问该目录vip/dashboard是否为vip用户，过滤不合格的用户
Route::get('vip/dashboard', function (){
    return view('vip.dashboard');
})->middleware(['auth','vip']);
