Redirect parameter transfer of vue-router
						
							
 1. When vue-router does nested routing, you can already receive the value when you jump to the product page, but I want to jump to the default ProA. After redirect redirection, I can jump to the ProA page, but product can"t get the value passed, for example, the value of id. How to solve this situation? 
 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
            }]
        }
    ]
						 
												
					 
					
						
 routes: [{
            path: '/',
            name: 'Index',
            component: Index
        },
        {
            path: '/product/:id',
            name: 'Product',
            redirect: '/product/producta/:id',
            component: Product
        },
        {
            path: '/product/producta/:id',
            name: 'ProA',
            component: ProA
        }, {
            path: '/product/productb',
            name: 'ProB',
            component: ProB
        }, {
            path: '/product/productc',
            name: 'ProC',
            component: ProC
        }
    ]
 
 first of all, because id is the value of PathValue,'/product/:id','/ product/:id/producta',id, you can get it. 
 and other properties, you can pass parameters in the following two ways. 
 passes parameters in the way of params. 
routes: [
        {
            path: '/product/:id',
            name: 'Product',
            // 1.
            redirect: {name:'/product/:id/producta'},
            component: Product,
            children: [{
                path: 'producta',
                // 2.
                name: '/product/:id/producta',
                component: ProA
            }]
        }
    ]
    
    //
   this.$router.push({
      name: '/product/:id/producta',
      params: {
        id: id,
        other: other
      }
    })    
 you have to use query to pass parameters in this way, and the redirected page can get the parameters of query. Access / product/1?x=1, redirect back / product/1/producta?x=1. 
routes: [
        {
            path: '/product/:id',
            name: 'Product',
            redirect: '/product/:id/producta',
            component: Product,
            children: [{
                path: 'producta',
                name: 'ProA',
                component: ProA
            }]
        }
    ]
    //
   this.$router.push({
      path: '/product/'+id,
      query: {
        other: other
      }
    })
