这个警告意味着在你的Vue组件中有重复的key值,这可能会导致更新错误。你需要确保key是唯一的。你可以使用类似于生成UUID的方式来为每个元素生成唯一的key,以避免这个问题。例如,在你的CommentList组件中,你可以这样写:
```
<template>
<div>
<div v-for="comment in comments" :key="generateUUID()">
{{ comment }}
</div>
</div>
</template>
<script>
export default {
data() {
return {
comments: ['comment1', 'comment2', 'comment3']
}
},
methods: {
generateUUID() {
// 生成唯一ID
return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
var r = Math.random() * 16 | 0, v = c == 'x' ? r : (r & 0x3 | 0x8);
return v.toString(16);
});
}
}
}
</script>
```
这样可以确保每个评论都有唯一的key。
