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

‘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);
