如何使用 controller case 按 ID 设置资源路由，并在控制器上获取 id

Question

没有资源，我可以像这样工作：

use App/Http/Controller/Aaa/XxxController as AaaXxxController;
use App/Http/Controller/Bbb/XxxController as BbbXxxController;
Route::get( "/aaa", [ AaaXxxController::class, "index" ] )
    ->defaults( "xxxID", "aaa" );
Route::get( "/bbb", [ BbbXxxController::class, "index" ] )
    ->defaults( "xxxID", "aaa" );

但是当我使用这样的资源方法时：

use App/Http/Controller/Aaa/XxxController as AaaXxxController;
use App/Http/Controller/Bbb/XxxController as BbbXxxController;
Route::resource( "/aaa", AaaXxxController::class)
    ->defaults( "xxxID", "aaa" );
Route::resource( "/bbb", BbbXxxController::class)
    ->defaults( "xxxID", "bbb" );

我收到错误信息： 方法 Illuminate\Routing\PendingResourceRegistration::defaults 不存在。

App/Http/Controller/Aaa/XxxController 和 App/Http/Controller/Aaa/XxxController 扩展了 App/Http/Controller/XxxController

App/Http/Controller/XxxController 像这样：

public function index( $xxxID ) {
    //...
}
......
public function update( Request $request, $xxxID, $id ) {
    //...
}
......
