推荐答案

该教程是为 www.firebase.com 上的旧版"Firebase 创建的.当您在那里创建项目时，默认情况下任何人都可以对其进行读写.

That tutorial was created for the "legacy" Firebase on www.firebase.com. When you create a project there, it is by default readable and writable by anyone.

我猜您是在新 Firebase 控制台上创建了您的项目.默认情况下，那里的项目只能由经过身份验证的用户读取和写入.

I guess that you created your project on the new Firebase Console. Projects there are by default only readable and writable by authenticated users.

目前最简单的解决方法(直到教程更新)是进入您项目的控制台中的数据库"面板，选择规则"选项卡并用以下规则替换内容:

The simplest workaround for the moment (until the tutorial gets updated) is to go into the Database panel in the console for you project, select the Rules tab and replace the contents with these rules:

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

这使您的新数据库对所有人都可读和可写，就像在旧版 Firebase 中一样.完成本教程后，请务必再次保护您的数据库，否则有人可能会开始滥用它.

This makes your new database readable and writeable by everyone, like in the legacy Firebase. Be certain to secure your database again once you're done with the tutorial, otherwise somebody is likely to start abusing it.
