javascript - 从本地机器访问 firebase 数据库

Question

我是 javascript、网络开发和 firebase 的新手。我正在尝试使用简单的脚本来学习它。

我写了下面的脚本:

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:

luca@luca-VirtualBox:~/PisoReview$ node index.js

End

我尝试了不同的选项，但我一直收到此权限被拒绝的错误。我该如何解决？

编辑 1:

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

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

据我所知，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了解更多信息。

检查和添加规则的步骤:

1. 登录https://console.firebase.google.com/并选择您的数据库。在侧面板上，您应该单击 database，然后在您的主面板上，将有两张卡片。一个是 Cloud Firestone，第二个是实时数据库。
2. 选择实时数据库。打开数据库后，您会在其顶部看到一个新菜单，上面写着“数据” | “规则” | “备份” | “用法”。
3. 点击规则。
4. 现在设置您自己的规则，以便能够从数据库中读取和写入。它接受 JSON 格式，例如:

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