我想对用户进行身份验证,并使用用户名(first和last)使用Firestore创建用户数据库。我可以创建用户,但无法同时创建数据库。
这是我的SessionStore,可用于注册和登录。通过注册,我想获取用户名并创建一个数据库。 (下面没有代码,因为什么都没用)
我是一个初学者,所以我希望能给出一个详尽的答案。
非常感谢!

Firebase身份验证管理用户身份验证-尽管它确实存储了某些联合身份提供者提供的其他信息(例如,个人资料图片URL),但它并非旨在成为个人资料管理解决方案。如果您想存储有关用户的其他信息,则可以使用Cloud Firestore或Firebase Realtime Database来实现。
Firebase用户对象仅具有有限数量的属性,主要是允许身份验证提供程序对用户进行身份验证。对于Swift,UserInfo定义了以下内容:
providerId
-提供者标识符uid
-用户的提供商的唯一ID displayName
-用户名(即他们的全名)photoURL
-用户的个人资料照片的网址(如果受身份验证提供程序支持!)email
-用户的电子邮件地址phoneNumber
-用户的电话号码,仅当用户通过电话号码auth进行身份验证时才可用因此,您需要做的是:
Auth.auth().createUser(withEmail: email, password: password)
这是一个示例实现。
别忘了:
