I'm currently working on integrating data patching with my Firestore database using http. My goal is to achieve this without relying on an external server, by utilizing Firebase Hosting and Functions.
Firstly, I set up my Firebase project and imported express, body-parser, and firebase-functions-helper into the functions.
Next, I configured my firebase.json file to link the source to the specific function:
"rewrites": [
{
"source": "/api/v1/**",
"function": "webApi"
}
]
Secondly, I wrote TypeScript code to upload data from the HTTP patch request to the Firestore database. This script is stored in functions/src/index.ts file.
import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
import * as firebaseHelper from 'firebase-functions-helper/dist';
import * as express from 'express';
import * as bodyParser from 'body-parser';
admin.initializeApp(functions.config().firebase);
const db = admin.firestore();
const app = express();
const main = express();
main.use(bodyParser.json());
main.use(bodyParser.urlencoded({extended: false}));
main.use('/api/v1/', app);
const sensorsCollection = 'sensors';
export const webApi = functions.https.onRequest(main);
app.patch('/sensor/:sensorId', async(req, res) => {
try{
await firebaseHelper.firestore.updateDocument(db, sensorsCollection, req.params.sensorId, req.body);
res.status(200).send('Update Success');
}catch(error){
res.status(204).send('Patch Error');
}
})
However, when attempting to use Postman to patch data at , I encounter a 404-error stating: "Cannot PATCH /api/v1/XXX"
I have verified that I am providing the correct document Id and ensuring proper JSON data. Can anyone provide assistance or insights on this issue?
