The Express app.post endpoint is not acknowledging incoming POST requests from Postman

I am facing an issue where my POST request using Postman to my express app is timing out.

Here is the request:

https://i.sstatic.net/UfL07.png

And here is the app:

import express from 'express'
import bodyParser from 'body-parser'
import path from 'path'

const app = express()

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

app.post('/', (req,res) => {
  console.log(req.body)

  if (req.body.inviteCode === "12") {
      res.json({value: "success"}) 
  } else {
      res.json({value: "fail"})
  }
})

app.listen(process.env.PORT || 3000, () => {
  console.log(`App listening on ${process.env.PORT || 3000}`)
})

console.log(req.body) shows an empty object {}

Any thoughts on what could be causing this issue?

Answer №1

Ensure that you are not omitting the inviteCode from the POST parameters in Postman, as noted in your screenshot where it should be included under the "Body" tab. Instead, you seem to be passing the inviteCode as a URL query parameter, which will then be accessed using req.query.inviteCode.

To make use of the query parameter (in the URL) in line with your Postman request:

app.post('/', (req,res) => {
  req.query.inviteCode === "99" ? res.json({value: "success"}) : res.json({value: "fail"})
})

Alternatively, if you want to utilize the inviteCode in the POST body, you'll need to correct your Postman request:

app.post('/', (req,res) => {
  console.log(req.body)

  req.body.inviteCode === "99" ? res.json({value: "success"}) : res.json({value: "fail"})
})
