如何保存到Firebase-Swift [英] How to save to Firebase - Swift

问题描述

可能我弄错了.

这是我尝试在fb身份验证后存储用户数据的方法:

This is how I try to store user data after fb auth:

    func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError?) {
    print("sds")
    print(result)
    if let error = error {
        print(error.localizedDescription)
        return
    }
    let credential = FIRFacebookAuthProvider.credentialWithAccessToken(FBSDKAccessToken.currentAccessToken().tokenString)

    FIRAuth.auth()?.signInWithCredential(credential) { (user, error) in

        if let email = user?.email
        {
           self.ref.child("users").child(user!.uid).setValue(["email": email])
        }
        if let photoURL = user?.photoURL?.absoluteString
        {
            self.ref.child("users").child(user!.uid).setValue(["photoURL": photoURL])
        }
    }}

当我在控制台中查看数据库时，我得到的仅仅是photoURL，看起来就像是在删除/覆盖后立即创建和创建电子邮件一样.

What I get when I look into database in console is only the photoURL, looks like email is created and immmediately after deleted/overriden.

将数据保存到Firebase的正确方法是什么?

What's the correct way to save data to firebase?

推荐答案

设置值时，将覆盖该路径上的所有内容.

When you set value you are overwriting everything at that path.

如果您只想替换某些值，则应使用:

If you only want to replace certain values you should use:

self.ref.child("users").child(user!.uid).child("photoURL").setValue(photoURL)

或替换/创建整个用户对象

Or replace/create entire user object

self.ref.child("users").child(user!.uid).setValue(["email": email, "photoURL": user?.photoURL?.absoluteString ?? ""])
