推荐答案
我只是给您一个方法.
-
在Cloud Firestore中，创建一个名为
device_ids的集合.
当用户尝试登录时，请检查您的手机的设备ID(例如 9876543210 )是否作为文档ID存在于您的集合 device_ids 中.
When a user tries to log in, check if device ID (let's say 9876543210) of his phone is present as document ID in your collection device_ids.
如果否，请使用该设备ID创建一个文档ID，并在此文档ID中创建一个 email 字段，并将给定的电子邮件ID放在此处，并允许用户注册.
If no, create a document ID with this device ID and in this document ID, create a email field and put given email ID here and allow user to sign up.
如果是，请转到特定的文档ID(此处为 9876543210 )并获取 email (即 hello@email.com ).现在，检查用户是否输入了此电子邮件，允许他登录，否则告诉他该设备已注册了提取的电子邮件ID，并且需要使用电子邮件ID登录.
If yes, go to the particular document ID (9876543210 here) and fetch the email (which is hello@email.com). Now check if user entered this email, allow him to log in else tell him the fetched email ID is already registered for this device and he needs to sign in with email ID.
