How to use the querystring Module In NodeJS
If the POST data is in URL-encoded format, you can use the querystring module to parse it.
const http = require('http');
const querystring = require('querystring');
const server = http.createServer((req, res) => {
if (req.method === 'POST') {
let data = '';
req.on('data', chunk => {
data += chunk.toString();
});
req.on('end', () => {
const postData = querystring.parse(data);
console.log('POST data:', postData);
res.end('Data received');
});
} else {
res.end('Send a POST request to this endpoint');
}
});
server.listen(3000, () => {
console.log('Server running on port 3000');
});
