Avoid using non-primitive value as key, use string/number value instead.Duplicate keys detected: '[o

今天在使用ant-design-vue时出现警告：
Avoid using non-primitive value as key, use string/number value instead.Duplicate keys detected: '[o
具体的问题就是有重复的键，可能会导致更新错误。

经过查找，发现报警告的的地方是
Avoid using non-primitive value as key, use string/number value instead.Duplicate keys detected: '[o
由于在v-for循环中，key值可能会出现重复，所以报了重复键警告。

解决：将key变成唯一的就行
Avoid using non-primitive value as key, use string/number value instead.Duplicate keys detected: '[o
