我尝试使用当前用户uid作为唯一标识符来存储关联的用户数据,因为实时数据库中存在用户uid,即ref.child(" User / uid"):

示例:当用户创建帐户时,会将其添加到Firebase控制台的身份验证部分,并让用户填写表单,如名字,姓氏,DOB等。如何将数据链接到用户UID在实时数据库中。

当您注册任何新用户时,您需要先注册代码:

 FIRAuth.auth()?.createUserWithEmail(UserEmail, password: UserPassword, completion: { (user, error) in

在成功回复中,您可以使用dictionary设置用户更多详细信息,并使用以下代码添加Child,使用SetValue方法:

ref.child("users").child(user!.uid).setValue(["Provider": self.txtPassword.text!,"Email": self.txtEmail.text!,"Firstname": self.txtFName.text!,"Lastname": self.txtLname.text!,"Phone": self.txtPhone.text!,])

此处 user!.uid 是主用户树中唯一的用户ID子项。

所以你的firebase树看起来像:

示例代码:

    @IBAction func ActionRegister(sender: UIButton) {

                let ref : FIRDatabaseReference!
                ref = FIRDatabase.database().reference()
                FIRAuth.auth()?.createUserWithEmail("abc@abc.com", password: "1234567", completion: { (user, error) in
                    if((error) != nil)
                    {
                        print("Error is = \(error?.localizedDescription)")
                    }
                    else
                    {

          // following method is a add user's  more details
          ref.child("users").child(user!.uid).setValue(["Provider": "1234566", "Email": "abc@abc.com", "Firstname": "nitin", "Lastname": "Gohel", "Phone": "12345678" ])

         //following method get the registers user details 
         ref.child("users").child(user!.uid).observeSingleEventOfType(.Value, withBlock: { snapshot in
                            let postDict = snapshot.value as! [String : AnyObject]
                            print("Error is = \(postDict)")
                        })    
                    }
                })

            }
