Firebase实时数据库Axios无法读取和写入

Question

我对firebase和node.js非常陌生。我想读取一些数据并将这些数据推送到我的Firebase实时数据库中。我尝试过：

var axios = require('axios');
var data = '{"currData":1,"alarms":1}';
var firebase = require('firebase');
require('firebase/database');

const firebaseConfig = {
  apiKey: "<myApiKey>",
  authDomain: "<myproject>.firebaseapp.com",
  databaseURL: "https://<myURL>.firebaseio.com",
  projectId: "<myProjectID>",
  storageBucket: "<myprojectName>.appspot.com",
  messagingSenderId: "<mySenderID>",
  appId: "1:<myappID>"
};
let app = firebase.initializeApp(firebaseConfig)
let db = app.database()
let sensorDataRef = db.ref('sensorData')

var config = {
  method: 'post',
  url: 'http://myIP/api',
  headers: {
    'Connection': 'keep-alive',
    'Origin': 'http://myIP',
    'Referer': 'http://myIP/',
    'Accept-Language': 'tr-TR,tr;q=0.9,en-US;q=0.8,en;q=0.7',
    'Cookie': 'username=myUsername; SID=mySID; group=myGroup'  },
  data : data
};


axios(config)
.then(function (response) {
   console.log(response.data);

  return firebase.database().ref().once('value').then(function(snapshot) {
    var username = (snapshot.val() && snapshot.val()) || 'Anonymous';
    console.log(snapshot.val())
  });

  var currentDatas = response.data["currData"];
  for(var attributename in currentDatas){
    // console.log(attributename+": "+  JSON.stringify(currentDatas[attributename]));
    firebase.database().ref('users/' + attributename).set(currentDatas[attributename]);
  }

})
.catch(function (error) {
  console.log(error);
});

当我运行节点this.js时，它不会将任何内容推送到数据库。但是我可以记录我的API数据。
