How Firebase Cloud functions handle HTTP post method?

Question

I have created Firebase Cloud Functions app, I created function with https.onRequest. and get data with req.body but there is not data there.

Can Firebase Cloud Functions can handle HTTP POST method?

This is my sample code:-

var functions = require('firebase-functions');  exports.testPost = functions.https.onRequest((req, res) => {     console.log(req.body); }); 

I tested by postman with POST method but didn't show result in Firebase log.

Functions built on Firebase can also use Express.js routers for handling GET/POST/PUT/DELETE, etc... is fully supported by Google, and is the recommended way to implement these types of functions.

More documentation can be found here:

https://firebase.google.com/docs/functions/http-events

Here's a working example built on Node.js

const functions = require('firebase-functions'); const express = require('express'); const cors = require('cors'); const app = express();  // Automatically allow cross-origin requests app.use(cors({ origin: true }));  app.get('/hello', (req, res) => {   res.end("Received GET request!");   });  app.post('/hello', (req, res) => {   res.end("Received POST request!");   });  // Expose Express API as a single Cloud Function: exports.widgets = functions.https.onRequest(app); 

Then, run firebase deploy, and that should compile your code and create the new "widgets" function. Note: You can rename widgets to anything you want. Ultimately, it will generate a URL for calling the function.
