laravel框架路由分组，中间件，命名空间，子域名

Route::group([], function () {
  Route::get('user/list', function () {});
  Route::get('user/info', function () {});
});

Route::middleware(['auth'])->group(function () {
  //使用auth中间件
  Route::get('user/list', function () {});
  //使用auth中间件
  Route::get('user/info', function () {});
});

Route::prefix('user')->group(function () {
  //处理/user/list
  Route::get('list', function () {});
  //处理/user/info
  Route::get('info', function () {});
});

Route::name('user.')->prefix('user')->group(function () {
  //处理/user/list，并命名为user.list
  Route::get('list', function () {})->name('list');
  //处理/user/info，并命名为user.info
  Route::get('info', function () {})->name('info');
});

Route::domain('{shop}.tmall.')->group(function () {
  //处理xxx.tmall./orders/xxx
  //$shop参数始终是分组路由的第一个参数
  Route::get('orders/{id}', function ($shop, $id) {
  });
  //处理xxx.tmall./products/xxx
  //$shop参数始终是分组路由的第一个参数
  Route::get('products/{id}', function ($shop, $id) {
  });
});

Route::namespace('Orders')->prefix('orders')->group(function () {
  //处理/orders/delete
  //并绑定到App\Http\Controllers\Orders下的DeleteController控制器的index方法
  Route::post('delete', 'DeleteController@index');
  //处理/orders/add
  //并绑定到App\Http\Controllers\Orders下的AddController控制器的index方法
  Route::post('add', 'AddController@index');
});
