在app.vue中把seller传进来<router-view seller="seller"></router-view>

2）在goods.vue把seller传递到shopcart.vue组件
在app.vue中把seller传进来<router-view seller="seller"></router-view>
过程：
1）在app.vue中把seller传递到goods组件<router-view seller="seller"></router-view>
2）在goods.vue把seller传递到shopcart.vue组件
<shopcart :delivery-price="seller.deliveryPrice" :min-price="seller.minPrice"></shopcart>
前提是在goods.vue中已经引入seller
props： {
seller：{
type: Object
}
}3)在shopcart中接收（props）这个值， <div class="desc">另需配送费{{deliveryPrice}}元</div>
export default {
props: {
deliveryPrice: {
type: Number,
default: 0
}
minPrice: {
type: Number,
default: 0
}
}
}
