产品页面，product.vue代码：

<template>

import axios from 'axios'
import { toast } from 'bulma-toast'
export default {

data() {
return {

}
},
mounted() {
this.getProduct()
},
methods: {
getProduct() {
const category_slug = this.$route.params.category_slug
const product_slug = this.$route.params.product_slug
axios
.get('/api/v1/products/${category_slug}/${product_slug}')
.then(response => {
this.product = response.data
})
.catch(error => {
console.log(error)
})
},
addToCart() {
if (isNaN(this.quantity) || this.quantity < 1) {
this.quantity = 1
}
const item = {
product: this.product,
quantity: this.quantity
}
this.$store.commit('addToCart', item)
toast({
message: 'The product was added to the cart!',
type: 'is-success',
dismissible: true,
pauseOnHover: true,
duration: 2000,
position: 'bottom-right',
})
}
}
}
</script>

我的产品/uls.py代码是：

from django.urls import path
from product import views
urlpatterns = [
path('latest-products/', views.LatestProductsList.as_view()),
path('products/<slug:category_slug>/<slug:product_slug>/', views.ProductDetail.as_view()),
]

我在vue应用程序中的main.js是：

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import axios from 'axios'
axios.defaults.baseURL = 'http://127.0.0.1:8000'
createApp(App).use(store).use(router, axios).mount('#app')

Answer 1

您使用"api/v1/"；在axios中。你忘了Django的URL模式或"；axios.defaults.baseURL"？

axios
.get('/api/v1/products/${category_slug}/${product_slug}')
.then(response => {
this.product = response.data
})
.catch(error => {
console.log(error)
})
