Vue 3 保持活动缓存路由
我正在使用 Vue 3 <keep-alive>
.当我不使用 :key
时,它会缓存(按预期不正确地跨不同的 URL).
I'm using Vue 3 <keep-alive>
. When I don't use :key
it caches (improperly across different URLs as expected).
通过添加
<router-view :key="$route.fullPath" v-slot="{ Component }">
<keep-alive>
<component :is="Component" />
</keep-alive>
</router-view>
我认为它只会在缓存键不存在的情况下进行 API 调用,这样当我转到不同的路线并返回时,它不会进行第二次 API 调用.
I would think that it only makes an API call if the cache key doesnt exist, so that when I go to a different route and come back, it won't make a second api call.
但是当我现在添加 :key="$route.fullPath"
时,即使我重新访问同一个 URL,它每次都会调用 API?
But when I add :key="$route.fullPath"
now it makes an API call every single time even if I revisit the same URL?
推荐答案
在 Vue 3 中,将 key
放在
而不是 <路由器视图>
:
In Vue 3, put the key
on the <component>
rather than the <router-view>
:
<router-view v-slot="{ Component }">
<keep-alive>
<component :is="Component" :key="$route.fullPath"></component>
</keep-alive>
</router-view>
