路由
Route::group(['middleware' => ['web']], function () {

Route::resource("articles", "ArticlesController");
Route::get("auth/login", 'Auth\AuthController@getLogin');
Route::post("auth/login", 'Auth\AuthController@postLogin');
Route::get("auth/register", 'Auth\AuthController@getRegister');
Route::post("auth/register", 'Auth\AuthController@postRegister');
Route::get("auth/logout", 'Auth\AuthController@logout');
Route::get('/', function () {
    return view('welcome');
});

});

指定注册后跳转路径

protected $redirectPath ="/articles";
