swift - 将 Firebase 身份验证与 Firebase 数据库连接

Question

我正在努力将 Firebase 身份验证与我的 iOS 应用上的 Firebase 数据库连接起来。

用户已成功通过身份验证并显示在 Firebase 的“身份验证”部分中，但数据(例如姓名/电子邮件)未显示在应存储的 Firebase 数据库中。我已将代码和调试区域的警告粘贴在下面。

代码:

 @objc func handleRegister() {

    guard let email = emailTextField.text, let password = passwordTextField.text, let name = nameTextField.text
        else {
            print("form is not valid")
            return
    }

    Auth.auth().createUser(withEmail: email, password: password, completion: { (res, err) in

        if let err = err {
            print(err)
            return
        }


        self.ref = Database.database().reference()
        let userId = Auth.auth().currentUser?.uid
        self.ref.child("users").child(userId!).setValue(["username": name, "email": email]) {
            (error:Error?, ref:DatabaseReference) in
            if let error = error {
                print("Data could not be saved: \(error).")
            } else {
                print("Data saved successfully!")
            }
        }

    })
}

Answer 1

首先，您的属性列表文件 plist 决定使用哪个 Firebase 项目，因此无需指定:

let ref = Database.database().reference(fromURL:"https://myawesomeproject29133.firebaseio.com/")

相反，您可以在 viewDidLoad() 函数上方创建一个名为 ref 的全局变量:

var ref: DatabaseReference!
override func viewDidLoad() {
        super.viewDidLoad()

}

在你的handleUser()中:

ref = Database.database().reference()
let userid =  Auth.auth().currentUser.uid
self.ref.child("users").child(userid).setValue(["name": name,"email": email])

Also, I highly recommend you to continue without saving someones password, Unless you encrypt them. You shouldn't store them nakedly. It's stored in Google's servers and you have absolutely zero reasons to view someone else's password.
