node.js - 如何使用 Node.js 获取和设置数据到 Firebase？

Question

我正在学习 Firebase 和 Node.js。我想从 Twitter 获取我的推文并将它们发送到 Firebase。我可以从 Twitter 检索我的推文，但无法将这些推文发送到 Firebase。

如何将这些从 Twitter 检索到的推文发送到 Firebase？

我试过以下代码:

var firebase = require('firebase');

// Initialize
var app = firebase.initializeApp({
    ServiceAccount: {
       projectId: "******",
       clientEmail: "****@gmail.com",
       privateKey: "-----BEGIN PRIVATE KEY-----\nkey\n-----END PRIVATE KEY-----\n"
    },
   databaseURL: "****.firebaseio.com"
}); 

// Set Sample Data
firebase.database().ref('/').set({
    username: "test",
    email: "test@mail.com"
});

我在控制台上收到以下错误:

 Debugger listening on port 5858
 crypto.js:279
  var ret = this._handle.sign(toBuf(key), null, passphrase);
                         ^

另外，这是我的 Firebase 规则，我将这些规则用于测试目的:

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

Answer 1

我解决了我的问题。我刚刚从 Firebase 控制台下载了 serviceAccount.json 文件并将其插入到我的项目中。 “服务帐户”文件包含我需要的所有内容。

var firebase = require('firebase');

firebase.initializeApp({
    databaseURL: 'https://*****.firebaseio.com',
    credential: 'myapp-13ad200fc320.json', // This is the serviceAccount.json file
});

然后下面的代码运行良好。

firebase.database().ref('/').set({
    username: "test",
    email: "test@mail.com"
});
