vue.js - Nuxt 3 动态页面更改 Url 但它不会更改内容并且只获取一次数据

Question

我有一个 products/index页面和products/[slug]在主要产品页面中，我有一个 NuxtLink更改页面并转到 products/[slug]并获取该产品的数据。

在第一次点击时我有一个正确的数据，但是当我点击后退或点击产品/索引页面然后尝试点击另一个产品时，我有我点击的第一个产品的信息，以及每个产品的信息，我再次获得了我点击的第一个产品的信息。

使用 console.log让我发现我的提取数据没有改变，我是不是错过了什么？

使用 :key和 :page-key在 <nuxtPage/>没用。

我点击的第一个产品

第二个产品，仍然没有变化，数据来自第一个产品

第三张图还是没有变化

我找到了解决方案我必须在 useFetch 中添加一个参数

const {data: productData, pending, refresh, error} = await useFetch(`http://127.0.0.1:8000/api/products/${slug}` , { initialCache: false })

因为 api 缓存并且不发送另一个请求所以 initialCache : false 它会发送另一个请求这种方式适用于主要产品，但在产品/[slug] 或博客/[slug] 中我认为你必须这样做，如果你有更好的方法请给我评论
