提取文档后从Firestore获取文档ID [英] Get document id from Firestore after fetching document

问题描述

成功获取文档后，如何获取Firestore文档的文档ID.我正在从这样的Firestore集合中获取用户数据

How can I get the document id of a firestore document after successfully fetching the document. I am fetching user data from firestore collections like this

const ref = await db.collection('users').where('phone', '==', phone)
            .where('password', '==', password).get();

执行此查询后，我有一个有效的文档.

I have a valid document after executing this query.

const data = ref.docs[0].data();

如何获取自动生成的文档ID?我尝试了 data.id 和 data.path ，它们返回的是未定义的.

How can I get the auto generated document id? I tried data.id and data.path, it is returning undefined.

推荐答案

在我的代码中，它实际上是在尝试获取数据ID，而不是文档ID我通过添加 const docRefId = ref.docs [0] .id;

In my code, it was actually trying to get the data id, instead of document id i got the document id by adding const docRefId = ref.docs[0].id;
