我不断得到“警告:列表中的每个子级在控制台中都应该有一个唯一的‘key’prop.”错误。经过一些检查,我发现需要为每个子级以及子级中的每个元素提供一个键。我在map函数中为Grid、Link和Card组件添加了键,但是错误仍然存在。卡片组件的孩子也需要钥匙吗?因为我觉得我没有足够的钥匙。还是我给错误的组件添加了密钥?

在开发里面,我们时常会遇到Warning: Each child in a list should have a unique "key" prop.的警告,在用map来渲染一个列表的时候经常碰到。当然,我们知道这时我们需要通过加一个key来解决这个问题,在react进行diff时,通过这个key来决定该节点在原始列表中的变动。
