我无法实现在 firebase 控制台中创建主题的云函数

Question

I am trying to implement a firebase function, which executes the creation of a topic in the firebase console.

Here is mi code:

exports.createGroupTopic = functions.database.ref("/FDSF/equipos/{equipoID}/").onWrite(event => {
let eventSnapshot = event.data;
let nombreEquipo = eventSnapshot.child('nombre').val();
console.log(nombreEquipo);
request({
  method: 'POST',
  url: 'https://iid.googleapis.com/iid/v1/IID_TOKEN/rel/topics/'+ nombreEquipo,
  headers: {
    'Content-Type':'application/json',
    'Content-Length': 0,
    'Authorization':'API_KEY'
  }
}, ...

After performing the deploy, observing the output of the console, I get the following error:

Answer 1

The value of the Authorization header is the server key prefixed by key= , as shown in this example in the documentation :

https://fcm.googleapis.com/fcm/send
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA

Prefix your server key with key= .
