Get request body from node.js's http.IncomingMessage

Question

I\'m trying to implement a simple HTTP endpoint for an application written in node.js. I\'ve created the HTTP server, but now I\'m stuck on reading the request content body:

Answer 1

'readable' event is wrong, it incorrectly adds an extra null character to the end of the body string

Processing the stream with chunks using 'data' event:

http.createServer((r, s) => {
    console.log(r.method, r.url, r.headers);
    let body = '';
    r.on('data', (chunk) => {
        body += chunk;
    });
    r.on('end', () => {
        console.log(body);
        s.write('OK'); 
        s.end(); 
    });
}).listen(42646);
