Android Firebase数据库身份验证电话权限被拒绝

我正在尝试编写应用程序，我有一些安全问题，我无法解决，我需要帮助。 我在firebase上使用用户电话身份验证，它工作正常。现在我想知道，当用户auth被授予用户id时，它会保存在数据库中，并且工作正常

但问题是，我使用此代码为新用户在数据库上写入的规则：

{
  "rules": {

      ".write": "auth == null ",
      ".read": "auth == null "              
  }
}

此代码用于新用户注册时：

  FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
   Firebase Ref = new Firebase( "database address" );
     Firebase usersRef = Ref.child( "Users" ).child( "user_id" );
       usersRef.setValue( user.getUid() );

当我使用此规则时，身份验证被拒绝：

{
  "rules": {

      ".write": "auth != null ",
      ".read": "auth != null "              
  }
}

但是我的用户已经注册了，我得到了他的id和电话表单身份验证用户如何解决这个安全问题

D/FirebaseAuth: Notifying id token listeners about user ( b3bizXzmH7XQfXWNvHCMVXzDHSx2 ).
D/FirebaseApp: Notifying auth state listeners.

试一试

我解决了我的问题，答案是：

   FirebaseUser user = task.getResult().getUser();
          mDatabase =FirebaseDatabase.getInstance().getReference();
                 String current_uid =user.getUid();
                mDatabase.child( "Users" ).child( "uid" ).setValue( current_uid );

谢谢你的回复，但问题来自我的代码，我解决了，谢谢。

   FirebaseUser user = task.getResult().getUser();
          mDatabase =FirebaseDatabase.getInstance().getReference();
                 String current_uid =user.getUid();
                mDatabase.child( "Users" ).child( "uid" ).setValue( current_uid );
