Question

我正在尝试编写一个函数，该函数在用户获得新评论并发送通知时触发。评论存储在/ Users / {user_id} / Notifications / {notification_id}中。用户将其设备通知令牌保存到/ users / {userID}

  class FlaskTestCase(unittest.TestCase):

     highscore = {1:2}

     def test_initial_word(self):
        with app.app_context():
             response = self.app.get("/final", data = dict(self.highscore , user = "test", score = 12)) 
             self.assertIn("quick and easy game", str(response.data))

这是package.json文件。一切都是最新的

 def test_initial_word(self):#Check if game.html has been created
        with app.app_context():
            response = self.app.get("/rules", data = dict(user = "test", score = 12)) 
            self.assertIn("test", str(response.data))

Firebase出现以下错误：

    'use strict'

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);

exports.sendNotif = functions.firestore.document('Users/{user_id}/Notifications/{notification_id}')
.onWrite((change,context) =>
{
    const user_id = context.params.user_id;
    const notification_id = context.params.notification_id;

    return admin.firestore().collection('Users').document(user_id).collection('Notifications').document(notification_id).get().then(queryResult=>{

      const from_user_id = queryResult.data().From;

      const from_data = admin.firestore().collection('Users').document(from_user_id).get();
      const to_data = admin.firestore().collection('Users').document(user_id).get();

      return Promise.all([from_data, to_data]).then(result => {

        const from_name = result[0].data().From;
        const to_name = result[1].data().From;

        console.log("FROM: " + from_name + "TO: " + to_name);

      });

    });

});

请检查阵列的长度（结果）。您应该记录结果。

 return Promise.all([from_data, to_data]).then(result => {
    console.log(result);

    const from_name = result[0].data().From;
    const to_name = result[1].data().From;

    console.log("FROM: " + from_name + "TO: " + to_name);

  });
