Tips for bypassing an argument using the POST method in NodeJS

Hey there! I started off by creating a question about passing over data using the GET method, but now I'm facing a new problem when trying to pass over data with the POST method. Below is my code snippet where things seem to be going wrong. My goal is to display: "Hello (Whatever the user passes as their name)!" If ExpressJS isn't working, can someone guide me on how to achieve this in JavaScript?

Check out the code below:

var server = require('./server');
var router = require('./router');
var requestHandlers = require('./requestHandlers');
 
var handle = {
  '/': requestHandlers.start,
  '/start': requestHandlers.start,
  '/upload': requestHandlers.upload,
  '/show': requestHandlers.show
};

var express = require('express')
var app = express()

app.post('/view/users/:name', function(req, res) {
    console.log(req.body.desc);
    res.end();
});

app.listen(8080, function () {
  console.log('listening on port 8000!')
}) 

When I try to pass over data, I encounter the error message "Cannot GET /view/users/John"

Answer №1

To retrieve the value stored in the path variable :name, you can access it from the req.params object.

app.get('/view/users/:name', function(req, res) {
    console.log(req.params.name);
    res.end();
});

Answer №2

It is essential to include the bodyParser module before defining your routes:

var bodyParser = require('body-parser')
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

By doing this, any data you send through the route will be easily accessible within the request object thanks to bodyParser.
