the editor is an error message when vscode, uses v-for. I know it"s actually fine and works normally, but it"s really uncomfortable to see the error report!
<div v-for="item in recommends" >
<a :href="item.linkUrl">
<img :src="item.picUrl" alt="">
</a>
</div> 
:key="item"
if the loop item has a unique key, set key to that key, otherwise do key
<div v-for="(item, index) in recommends" :key="index">
<a :href="item.linkUrl">
<img :src="item.picUrl" alt="">
</a>
</div>Previous: Wechat login authorization problem
