如何获取Firebase生成的ID？-HowtogetFirebasegeneratedID?

I want to update an item in my application so I need an id that Firebase creates:

我想更新应用中的项目，因此我需要Firebase创建的ID：

https://db.firebaseio.com/userid/books/-L6_e2KsseGzwM8a0YUv

https://db.firebaseio.com/userid/books/-L6_e2KsseGzwM8a0YUv

The problem is that Firebase returns an object of objects, so I returned Object.values(data) and now I don't have that id which I could maybe access if Firebase returns classic array..

问题是Firebase返回一个对象对象，所以我返回了Object.values（数据），现在我没有那个我可以访问的id，如果Firebase返回经典数组的话。
