curl, node: posting JSON data to node server - node.js

Question

I'm trying to test a small node server I've written with CURL and for some reason this fails. My script looks like this:
http.createServer(function (req, res)
{
"use strict";
res.writeHead(200, { 'Content-Type': 'text/plain' });
var queryObject = url.parse(req.url, true).query;
if (queryObject) {
if (queryObject.launch === "yes") {
launch();
else {
// what came through?
console.log(req.body);
}
}
}).listen(getPort(), '0.0.0.0');
When I point my browser to:
http://localhost:3000/foo.js?launch=yes
that works fine. My hope is to send some data via JSON so I added a section to see if I could read the body part of the request (the 'else' block). However, when I do this in Curl, I get 'undefined':
curl.exe -i -X POST -H "Content-Type: application/json" -d '{"username":"xyz","password":"xyz"}' http://localhost:3000/foo.js?moo=yes
I'm not sure why this fails.

The problem is that you are treating both requests as if they where GET requests.
In this example I use a different logic for each method. Consider that the req object acts as a ReadStream.
var http = require('http'),
url = require('url');
http.createServer(function (req, res) {
"use strict";
if (req.method == 'POST') {
console.log("POST");
var body = '';
req.on('data', function (data) {
body += data;
console.log("Partial body: " + body);
});
req.on('end', function () {
console.log("Body: " + body);
});
res.writeHead(200, {'Content-Type': 'text/html'});
res.end('post received');
} else {
var queryObject = url.parse(req.url, true).query;
console.log("GET");
res.writeHead(200, {'Content-Type': 'text/plain'});
if (queryObject.launch === "yes") {
res.end("LAUNCHED");
} else {
res.end("NOT LAUNCHED");
}
}
res.writeHead(200, { 'Content-Type': 'text/plain' });
}).listen(3000, '0.0.0.0');
