How to Send a payload to a firebase OnRequest Function-CodePudding

I have a firebase post function that I am trying to send some data to but the problem I am having is that I the body comes empty. I am using express for the function.

const functions = require("firebase-functions");
const admin = require("firebase-admin");
const express = require("express");
const request = require("request");
const moment = require("moment");
const cors = require("cors");
// const bodyParser = require("body-parser");
admin.initializeApp();
const app = express();

app.use(cors());

app.use(express.json({limit: "10kb"}));

// Mpesa Express
app.post("/express", _accessToken, (req, res) => {
  console.log(JSON.stringify("FELOOOOOO", req.body));
  console.log(JSON.stringify("felix"));

 res.status(200).json(req.body);
 
});

exports.main = functions.https.onRequest(app);

The functions run but when I log the req.body it comes empty. I have used postman to send the post request but still, the req.body comes empty despite passing in some data. Kindly help solve the error. below is a screenshot of the postman request

CodePudding user response：

You seem to be sending the data correctly but are incorrectly using JSON.stringify(). The object is the first argument, not the second. Make it JSON.stringify(req.body) - that should work.

You can read up more about the function over at MDN docs: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify
