FCM考虑了针对Firebase的云功能的外部网络

Question

I am getting an error stating external network is not accessible, which makes sense as I am on the free tier of Firebase. But I thought Firebase services were included in the free tier, and as such, I should be able to use FCM.

Here is the code I am using for my index.js for the functions.

var functions = require('firebase-functions');
var admin = require("firebase-admin");

admin.initializeApp(functions.config().firebase);

exports.buttonPress = functions.https.onRequest((req, res) => {
    let testToken = "TOKEN";
    let payload = {
        data: {
            type: req.body.type
        }
    };
    admin.messaging().sendToDevice(testToken, payload)
        .then(function (response) {
            ...
        })
        .catch(function (error) {
            ...
        });
});

Billing account not configured. External network is not accessible and quotas are severily limited. Configure billing account to remove these restrictions.

This message now shows up for any Cloud Functions that are invoked from projects that are on the free tier. It doesn't mean that any calls have actively been blocked, just they calls to external services will be blocked for this project.

We're looking if we can get the message removed.

To sent FCM through cloud functions, you can use the code below. Check log if you are getting right tokens.

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

exports.sendNotification = functions.firestore
.document('/users/{documentId}')
.onWrite((change, context) => {
   console.log("DOCUMENT ID : " + context.params.documentId);

   //Get all data 

   const payload = {
            notification: {
              title: 'Test title!',
              body: `${userName} sent you a following request.`
              // icon: follower.photoURL
            }
          };

    admin.messaging().sendToDevice(followedFCMToken, payload)
        .then(function (response) {
            console.log("Push response : " + response);
            return response
        })
        .catch(function (error) {
            console.error("Error in sending push");
        });
});

For Free tier account, Firebase has imposed a restriction on accessing external service that is not within google's network.

To get to the root cause of the problem just go to the Firebase console and check your functions's log. The log will show exactly what service or packages you installed is trying to make external HTTP request.
