2. clasp init & clasp push
3. deploy this as Library and memo Library ID from Project settings
4. add Library with memoed ID from Script Editor

create Reader from Apps Script Project

const client = GasHttpClient.createClient(UrlFetchApp, 'https://example.com')
client.opts({
  method:  'post',
  payload: {
    thank: 'you',
    very:  'mutch',
    exp:   new Date('2017-07-22').getTime()
  },
  withJWT: {
    'secret':      'abc',
    'headerField': 'X-GAS-JWT',
  }
})

const response = client.requestJSON('/post')

Note: requestJSON() add header Accept: application/json and Content-Type: application/json automatically.

You can use opts(), headers() and buildParam() or buildParamJSON() for tesing of building HTTP request, without deploying to Google Apps Script to do real HTTP request.
