Question

我是JavaScript，Web开发和Firebase的新手。我正在尝试使用简单的脚本来学习它。

我写了以下脚本：

console.log("Starting")
var firebase = require("firebase/app");

// Add the Firebase products that you want to use
require("firebase/auth");
require("firebase/firestore");
require('firebase/database');


console.log("Firebase was imported")

var firebaseConfig = {
    apiKey: ...,
    authDomain: ...,
    databaseURL: ...,
    projectId: ...,
    storageBucket: ...,
    messagingSenderId: ...,
    appId: ...
  };
  // Initialize Firebase

console.log("Firebase  initializition")
firebase.initializeApp(firebaseConfig);

console.log("connect to db")
var database = firebase.database();


function writeApartmentData(apartmentId, street_, number_, floor_, door_) {
    firebase.database().ref('apartments/' + apartmentId).set({
      street: street_,
      number: number_,
      floor: floor_,
      door: door_

    });
  }

console.log("write apartment data")
writeApartmentData(1, "calle amalia", 18, 3, "B")



console.log("End");

我得到以下信息：

我尝试了其他选项，但我不断收到此“拒绝权限”错误。我该如何解决？

编辑1：

在我的Firebase仪表板中。在Database - Rules部分中，我有：

service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if true;
    }
  }
}

据我了解，这应该意味着每个人都可以访问该数据库。

我认为您应该配置数据库规则才能使用它。检查以下link，以了解更多信息。

检查和添加规则的步骤：

登录https://console.firebase.google.com/并选择您的数据库。在侧面板上，应单击database，然后在主面板上将有两张卡。一种是Cloud Firestone，另一种是实时数据库。
选择实时数据库。打开数据库后，您将在其顶部有一个新菜单，上面显示“ Data” |“ Data”。 “规则” | “备份” | “用法”。
单击Rules。
现在设置您自己的规则以能够从数据库读取和写入。它接受JSON格式，例如：

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

如果要查找有关此选项的更多信息，请检查我发布的链接。我希望它能解决您的问题。
