## 路由組 To help organize routes into logical groups, the`Slim\App`also provides a`group()`method. Each group’s route pattern is prepended to the routes or groups contained within it, and any placeholder arguments in the group pattern are ultimately made available to the nested routes: > 為了幫助將路由組織到邏輯組中，`Slim\App`還提供了一個`group()`方法。 > > 每個組的路由模式被預先寫入其中包含的路由或組，組模式中的任何占位符參數最終都可用于嵌套路由: ~~~php $app->group('/users/{id:[0-9]+}', function (RouteCollectorProxy $group) { $group->map(['GET', 'DELETE', 'PATCH', 'PUT'], '', function ($request, $response, $args) { // Find, delete, patch or replace user identified by $args['id'] })->setName('user'); $group->get('/reset-password', function ($request, $response, $args) { // Route for /users/{id:[0-9]+}/reset-password // Reset the password for user identified by $args['id'] })->setName('user-password-reset'); }); ~~~ The group pattern can be empty, enabling the logical grouping of routes that do not share a common pattern. > 組模式可以為空，從而支持不共享公共模式的路由的邏輯分組。 ~~~php $app->group('', function (RouteCollectorProxy $group) { $group->get('/billing', function ($request, $response, $args) { // Route for /billing }); $group->get('/invoice/{id:[0-9]+}', function ($request, $response, $args) { // Route for /invoice/{id:[0-9]+} }); })->add(new GroupMiddleware()); ~~~ Note inside the group closure, Slim binds the closure to the container instance. * inside route closure,`$this`is bound to the instance of`Psr\Container\ContainerInterface` > 注意，在組閉包內部，Slim將閉包綁定到容器實例。 > > 在路由閉包內部，`$this`被綁定到`Psr\Container\ContainerInterface`的實例
