步骤1：生成Auth

在项目建立完成后，生成内置Auth组件：

php artisan make:auth

步骤2：添加guard

打开config\auth.php,为方便前后台用户切换，项目共用Users表

'guards' => [        //...        'admin' => [            'driver' => 'session',            'provider' => 'users',        ],        //...    ],

步骤3：实现基类

class AdminController extends BaseController{    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;    public function __construct()    {        $this->middleware('auth:admin');    }}

步骤4：实现后台登陆控制器

新建appcontrollersAdminLoginController.php

    middleware('guest:admin')->except('logout');    }    /**     * 重写登陆页面     * @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View     */    public function showLoginForm()    {        return view('backend.login');    }    /**     * 重写退出方法     * @param Request $request     * @return \Illuminate\Http\RedirectResponse|\Illuminate\Routing\Redirector     */    public function logout(Request $request)    {        $this->guard()->logout();        $request->session()->flush();        $request->session()->regenerate();        return redirect('/admin/login');    }    /**     * 重写guard认证     * @return mixed     */    protected function guard()    {        return Auth::guard('admin');    }}

步骤5：实现登陆后跳转到不同路径

app\Middleware\RedirectIfAuthenticated.php

public function handle($request, Closure $next, $guard = null){        if (Auth::guard($guard)->check()) {            $path = $guard ? '/admin' : '/home';            return redirect($path);        }        return $next($request);}

步骤6：实现未通过认证跳转不同登陆页

app\Exceptions\Handler.php

/**     * 重写实现未认证用户跳转至相应登陆页     * @param \Illuminate\Http\Request $request     * @param AuthenticationException $exception     * @return \Illuminate\Http\JsonResponse|\Illuminate\Http\RedirectResponse     */    protected function unauthenticated($request, AuthenticationException $exception)    {        if($request->expectsJson()){            return response()->json(['message' => $exception->getMessage()], 401);        }else{            return in_array('admin', $exception->guards()) ? return redirect()->guest('/admin/login') : redirect()->guest('login');        }    }

完成
