1、vue-router 做嵌套路由傳值的時候，跳轉到product頁面的時候，已經能夠收到傳過來的值，但是我想跳的是默認ProA ，做了redirect重定向，能夠跳轉到ProA頁面，但是product獲取不到傳過來的值，比如說id的值，這種情況要怎么解決？  routes: [{            path: '/',            name: 'Index',            component: Index         },         {            path: '/product/:id',            name: 'Product',            redirect: '/product/:id/producta',            component: Product,            children: [{                path: 'producta',                name: 'ProA',                component: ProA             }, {                path: 'productb',                name: 'ProB',                component: ProB             }, {                path: 'productc',                name: 'ProC',                component: ProC             }]         }     ]
