https: can not handle large data, I can't get all the data chunk when fetch large data, it's pending all the time.

here is my code：

// https://s.rokidcdn.com/homebase/upload/KDKs0M1_W.json // large data
// https://s.rokidcdn.com/homebase/upload/XYbP8HhjV.json // small data

var https = require('https')
var url = 'https://s.rokidcdn.com/homebase/upload/KDKs0M1_W.json'

var req = https.request(url, (res) => {
  console.log('statusCode:', res.statusCode)
  console.log('data length ========= ', res.headers['content-length'])

  var body = []
  res.on('data', chunk => {
    body.push(chunk)
    console.log('chunk length === ', chunk.length, Buffer.concat(body).length)
  })

  res.on('end', _ => {
    console.log('on end ===========')
    console.log(Buffer.concat(body).toString())
  })
})

req.on('error', e => {
  console.error(e)
})

req.end()

and here is the log when run the script:

iotjs req.js
statusCode: 200
data length =========  191561
chunk length ===  499 499
chunk length ===  1400 1899
chunk length ===  1400 3299
chunk length ===  1400 4699
chunk length ===  1400 6099
chunk length ===  1400 7499
chunk length ===  1400 8899
chunk length ===  1400 10299
chunk length ===  1400 11699
chunk length ===  1400 13099
chunk length ===  1400 14499
chunk length ===  1400 15899
chunk length ===  1400 17299
chunk length ===  1400 18699
chunk length ===  1400 20099
chunk length ===  1400 21499
chunk length ===  1400 22899
chunk length ===  1400 24299
chunk length ===  1400 25699
chunk length ===  1400 27099
chunk length ===  1400 28499

then it's pending all the time.

Tested over http, it works. Should be confirmed if it's related to tls or https.

so the upper limit of download is only 28KB？
is there any testing for upload upper limit?
