### 1. 创建后台用户模型和数据表 ###

php artisan make:model Models/Admin -m

### 2. 设置表字段 ###

public function up()
        {
            Schema::create('admins', function (Blueprint $table) {
                $table->bigIncrements('id');
                $table->string('name',100)->comment('用户名');
                $table->string('email',100)->comment('邮箱');
                $table->string('password',100)->comment('密码');
                $table->timestamp('email_verified_at')->nullable();
                $table->rememberToken();
                $table->timestamps();
            });
        }

### 3. 填充数据表 AdminsTableSeeder.php ###

public function run()
        {
            DB::table('admins')->insert([
                  'name' => 'admin',
                  'email' => '1065628795@qq.com',
                  'password' => bcrypt('123456'),
            ]);
        }

### 4. 新建后端路由 admin.php ###

Route::get('admin/login', 'Admin\LoginController@getLogin')->name('admin.login');
    Route::post('admin/login', 'Admin\LoginController@postLogin');
    Route::get('admin/logout', 'Admin\LoginController@logout');

### 5. 修改app/Providers/RouteServiceProvider.php ###

public function map()
        {
            $this->mapApiRoutes();
    
            $this->mapWebRoutes();
        
            $this->mapAdminRoutes();
            //
        }
    ...
    protected function mapAdminRoutes()
        {
            Route::middleware('web')
                ->namespace($this->namespace)
                ->group(base_path('routes/admin.php'));
        }

### 6. 修改config/auth.php ###

'guards' => [
            'web' => [
                'driver' => 'session',
                'provider' => 'users',
            ],
            'admin' => [
                'driver' => 'session',
                'provider' => 'admins',
            ],
            'api' => [
                'driver' => 'token',
                'provider' => 'users',
                'hash' => false,
            ],
        ],
    ...
    
    'providers' => [
            'users' => [
                'driver' => 'eloquent',
                'model' => App\Models\User::class,
            ],
            'admins' => [
                'driver' => 'eloquent',
                'model' => App\Models\Admin::class,
            ],
            // 'users' => [
            //     'driver' => 'database',
            //     'table' => 'users',
            // ],
        ],

### 7. 登录控制器 LoginController ###

namespace App\Http\Controllers\Admin;
    
    use Illuminate\Http\Request;
    use Illuminate\Foundation\Auth\AuthenticatesUsers;
        
    class LoginController extends AdminController
    {
        /**
         * 设置成功登录后转向的页面:
         *
         * @var string
         */
        public $redirectPath = 'admin.index';
        
        /**
         * 设置退出登录后转向的页面
         *
         * @var string
         */
        protected $redirectAfterLogout = 'admin/login';
            
        /*
         |--------------------------------------------------------------------------
         | Registration & Login Controller
         |--------------------------------------------------------------------------
         |
         | This controller handles the registration of new users, as well as the
         | authentication of existing users. By default, this controller uses
         | a simple trait to add these behaviors. Why don't you explore it?
         |
        */
            
        use AuthenticatesUsers;
            
        /**
         * Create a new authentication controller instance.
         *
         * @return void
         */
        public function __construct()
        {
            $this->middleware('guest:admin', ['except' => 'logout']);
        }
            
        /**
         * Show the application login form.
         *
         * @return \Illuminate\Http\Response
         */
        public function getLogin()
        {
            return view('admin.login');
        }
            
        /**
         * Handle a login request to the application.
         *
         * @param  \Illuminate\Http\Request $request
         *
         * @return \Illuminate\Http\Response
         */
        public function postLogin(Request $request)
        {
            $field = filter_var($request->input('username'), FILTER_VALIDATE_EMAIL) ? 'email' : 'username';
                
            $request->request->add([$field => $request->input('username')]);
                
            $credentials = $request->only($field, 'password');
                
            if (auth('admin')->attempt($credentials, $request->has('remember'))) {
                return redirect()->intended(route($this->redirectPath));
            }
                
            return redirect('admin/login')->withInput()->withErrors([$this->username() => [trans('auth.failed')]], 'login');
        }
            
        /**
         * Log the user out of the application.
         *
         * @return \Illuminate\Http\Response
         */
        public function logout()
        {
            auth('admin')->logout();
                
            return redirect($this->redirectAfterLogout);
        }
    }

### 8. 登录页面 login.blade.php ###

<form action="/" method="post">
            {{ csrf_field() }}
            <input type="text" placeholder="用户名" name="name"/>
            <input type="password" placeholder="密码" name="password"/>
            <button type="submit" >登录</button>
    </form>

### 9. 页面提示信息展示以及后台登录成功用户名信息展示 message.blade.php ###

@if(session()->has("errormsg"))
                <div class="alert alert-error ">
                    <button class="close" data-dismiss="alert"></button>
                    <span>{{ session("errormsg") }}.</span>
                </div>
             @endif
    //用户信息展示
    {{ auth()->user()->name }}
