Arduino SIM800L Firestore database security rules - arduino

Question

I want to post data in a Firestore database using Arduino with the SIM800L module.
I have already done a test in which I use Firebase Database Realtime which works well but without configuring the security.
Now I use a Firestore database by configuring security.
I read the official documentation but I do not know how Arduino should make the request to enter the authentication information.

Answer 1

Update my question.
here is the code that I use with the Realtime database without security configuration.
const admin = require('firebase-admin');
const functions = require('firebase-functions');
admin.initializeApp();
exports.helloWorld = functions.https.onRequest((req, res) => {
res.send('identifiant: ' + req.body.identifiant);
});
exports.insertMesure = functions.https.onRequest((req, res) => {
const identifiant = req.body.identifiant;
const temperatureAir = req.body.temperatureAir;
const humiditeSol = req.body.humiditeSol;
const humiditeAir = req.body.humiditeAir;
const niveauEau = req.body.niveauEau;
const phSol = req.body.phSol;
const dateMesure = Date.now();
const mesure = {
temperatureAir: temperatureAir,
humiditeSol: humiditeSol,
humiditeAir: humiditeAir,
niveauEau: niveauEau,
phSol: phSol,
dateMesure: dateMesure
};
const dbRef = admin.database().ref('/users/' + identifiant + '/mesures');
dbRef.push(mesure)
.then(() => {
return res.status(200).send('oK');
})
.catch(err => {
res.status(500).send('Error: ' + err);
});
});
The structure of my database:
- users
- {user_id}
- mesures
Replaced
user_id
by the identifier attribute
identifiant
of the request sent by Arduino
