node socket hang up error with http

Question

I followed the node http document to write a delete request to the local server, but receive the socket hang up error, similar question I checked are:

NodeJS - What does “socket hang up” actually mean?
Error: socket hang up using node v0.12.0

but no one actually work for my scenario.

I believe it is the code error because I use postman it works for me, following is my code

var options = {
    hostname: 'localhost',
    port: 3000,
    path: '/accounts/abc'
    method: 'DELETE',
    headers: {
        'Content-Type': 'application/json; charset=utf-8'
    }
};

var order = {
    "secret": "abc_secret"
};

var content = JSON.stringify(order);
var req = http.request(options, function(res) {
    console.log('STATUS: ' + res.statusCode);
    res.on('data', function(chunk) {
        console.log('resp: ' + chunk);
    });
});


req.on('error', function(err) {
    console.error('error: ' , err.stack.split("\n"));
});

req.write(content);

req.end();

and the errors are:

error:  [ 'Error: socket hang up',
  '    at createHangUpError (_http_client.js:215:15)',
  '    at TLSSocket.socketOnEnd (_http_client.js:300:23)',
  '    at TLSSocket.emit (events.js:129:20)',
  '    at _stream_readable.js:908:16',
  '    at process._tickCallback (node.js:355:11)' ]

Apparently, the request header does not have content length. Therefore, whatever you wrote in the write function will be ignored. Hope this is the root cause.

yes, both DELETE and POST method need the content length to be set

for me - solved by add Content-Length header.

 headers: {
    'Content-Type': 'application/json; charset=utf-8',
    'Content-Length': Buffer.byteLength(JSON.stringify(order))
 }
