Laravel 路线 [仪表板] 未定义

Question

今天第一次尝试玩 Laravel。当我尝试访问时出现以下错误：

无效参数异常

路线 [仪表板] 未定义。

路线/web.php

Route::get('/', ['as' => '/', 'uses' => 'LoginController@getLogin']);
Route::post('/login', ['as' => 'login', 'uses' => 'LoginController@postLogin']);
Route::get('/logout', ['as' => 'logout', 'uses' => 'LoginController@getLogout']);

Route::group(['middleware' => ['authenticate', 'roles']], function (){
    Route::get('/dashboard', ['as' => 'dashboard', 'uses' => 'DashboardController@dashboard']);
});

登录控制器.php

class LoginController extends Controller
{
    use AuthenticatesUsers;

    protected $username = 'username';
    protected $redirectTo = '/';
    protected $guard = 'web';

    public function getLogin()
    {
        if (Auth::guard('web'))
        {
            return redirect()->route('dashboard');
        }
        return view('login');
    }

    public function postLogin(Request $request)
    {
        $auth = Auth::guard('web')->attempt([
            'username' => $request->username,
            'password' => $request->password,
            'active' => 1]);
        if ($auth)
        {
            return redirect()->route('dashboard');
        }
        return redirect()->route('/');
    }

    public function getLogout()
    {
        Auth::guard('web')->logout();
        return redirect()->route('/');
    }
}

Answer 1

as喜欢name()。您应该使用两者之一：

Route::group(['middleware' => ['authenticate', 'roles']], function (){
    Route::get('/dashboard', 'DashboardController@dashboard')->name('dashboard');
});

或者

Route::group(['middleware' => ['authenticate', 'roles']], function (){
    Route::get('/dashboard', [
    'as' => 'dashboard', 
    'uses' => 'DashboardController@dashboard']);
});

之后，您可以使用以下命令清除路由缓存php artisan route:clear

最后，您可以用来php artisan route:list列出所有路由和操作绑定
