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:

http.createServer(function(r, s) {     console.log(r.method, r.url, r.headers);     console.log(r.read());     s.write("OK");      s.end();  }).listen(42646); 

Request's method, URL and headers are printed correctly, but r.read() is always NULL. I can say it's not a problem in how the request is made, because content-length header is greater than zero on server side.

Documentation says r is a http.IncomingMessage object that implements the Readable Stream interface, so why it's not working?

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);
