实时数据库未将数据推送到 Firebase

Question

我正在使用实时数据库来保存用户信息，但问题是它根本不工作，同时存储和云火库正常工作，尝试更改规则，尝试不同的方法但没有一个真正有效，如果有人可以帮助谢谢你提前。

• 这是我的代码

class CustomerRegistrationActivity : AppCompatActivity() {
    private lateinit var imageDownloadUrl : String
    private var imageUrl : Uri? = null
    private lateinit var firebaseAuth: FirebaseAuth
    private lateinit var databaseReference: DatabaseReference
    private lateinit var storageReference: StorageReference
    private var _binding : ActivityCustomerRegistrationBinding?  = null
    private val binding get() = _binding!!
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        _binding = ActivityCustomerRegistrationBinding.inflate(layoutInflater)
        setContentView(binding.root)


        init()

        binding.register.setOnClickListener {
            binding.register.startAnimation()
            registerNewCustomer()
        }

        binding.customerImg.setOnClickListener {

• 实时数据库规则

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

Answer 1

尝试在 push 时删除 .await() 并将 db 规则设置为 true

".read": true,
".write": true
