推荐答案
您无法更改密钥的名称，没有用于执行此操作的API.如果要更改密钥的名称，则需要将该特定对象复制到另一个位置，更改名称并删除旧的密钥.但是在Firebase中无法更改密钥名称.
You cannot change the name of your keys, there is no API for doing that. If you want to change the name of a key you need to copy that particular object to another location, change the name and delete the old one. But to change the name of key is not possible in Firebase.
