php – Laravel 5.2嵌套路由组与中间件

> Session :: flash无效
>奇怪的路线参数

问题1

我遇到了一个错误,Session :: flash无法正常工作.
我也发现了一种解决方法,但它很奇怪.

我认为嵌套组和中间件有问题.

码：

Route::group(['middleware' => 'web'],function () {
    Route::group([
            'prefix' => '{locale}','middleware' => ['localized']
        ],function($locale)
    {
        Route::resource('/','ProductController',['only' => ['index']]);
        Route::get('/cart','CartController@show')->name('show-shopping-cart');
    });

    Route::patch('/cart','CartController@update')->name('patch-cart');
});

现在..
如果我以这种方式修改kernel.php,这将有效：

从

protected $middleware = [
    IlluminateFoundationHttpMiddlewareCheckForMaintenanceMode::class,];

protected $middlewareGroups = [
    'web' => [
        AppHttpMiddlewareEncryptCookies::class,IlluminateCookieMiddlewareAddQueuedCookiesToResponse::class,IlluminateSessionMiddlewareStartSession::class,IlluminateViewMiddlewareShareErrorsFromSession::class,AppHttpMiddlewareVerifyCsrfToken::class,],'api' => [
        'throttle:60,1',];

至

protected $middleware = [
    IlluminateFoundationHttpMiddlewareCheckForMaintenanceMode::class,AppHttpMiddlewareEncryptCookies::class,];

protected $middlewareGroups = [
    'web' => [
    ],];

你怎么看待这件事？

问题2

在上面的路由中,ProductController @ show获得了2个参数：locale和id.

例如,如果我导航到/ en / 4

function show($id){
    dd($id);
}

$id =“en”

它会以这种方式工作：

function show($locale,$id){
    dd($id);
}

这是设计的吗？
如果有,是否有办法避免将$locale传递给组内的路由？
