Firebase：设置其他用户属性 [英] Firebase: setting additional user properties

问题描述

我想向Firebase用户对象添加一个属性。 用户文档说，我只能使用Firebase实时数据库存储其他属性。

I'd like to add a property to a Firebase user object. The user documentation says that I can only store additional properties using the Firebase real time database.

我不确定在实践中如何运作。

以下意思是在实践中？

您不能直接向Firebase User对象添加其他属性;
，您可以将其他属性存储在Firebase
实时数据库中。

You cannot add other properties to the Firebase User object directly; instead, you can store the additional properties in your Firebase Realtime Database.

我将其解释为以下：

您无法修改 FIRUser 对象，但您可以将其与其他对象组合

"you cannot modify properties of a FIRUser object but you can combine this with additional objects"

我发现设置功能文档，我插入以这种方式：

I found the set function documentation which I interpet in this way:

  var userRef = ref.child("users");
  userRef.set({
    newfield: "value"
  });

这是一个明智的做法吗？

Is this a sensible approach?

推荐答案

你几乎在那里在传统Firebase文档中，我们在存储此类附加用户数据。

You're almost there. In the legacy Firebase documentation, we had a section on storing such additional user data.

关键是在用户的 uid 下存储附加信息：

The key is to store the additional information under the user's uid:

    let newUser = [
        "provider": authData.provider,
        "displayName": authData.providerData["displayName"] as? NSString as? String
    ]
    // Create a child path with a key set to the uid underneath the "users" node
    // This creates a URL path like the following:
    //  - https://<YOUR-FIREBASE-APP>.firebaseio.com/users/<uid>
    ref.childByAppendingPath("users")
       .childByAppendingPath(authData.uid).setValue(newUser)

我已经添加了一个注释，我们应该在新的文档中添加这些信息。我们只需要找到一个好的地方。

I've added a note that we should add this information in the new documentation too. We just need to find a good spot for it.
