Creation of custom package

[saumya_gandhi@outlook.com]

You need to modify the upgrade_request function in websocket library:

Code:

local upgrade_request = function(req, key)
  local format = string.format
  local lines = {
    format('GET %s HTTP/1.1',req.path or ''),
    format('Host: %s',req.host),
    'Upgrade: websocket',
    'Connection: Upgrade',
    format('Sec-WebSocket-Key: %s',key),
    'Sec-WebSocket-Version: 13',
  }
  if self.protocol then
    tinsert(lines, format('Sec-WebSocket-Protocol: %s', self.protocol))
  end
  if req.port and req.port ~= 80 then
    lines[2] = format('Host: %s:%d',req.host,req.port)
  end
  if req.userinfo then
    local auth = format('Authorization: Basic %s', base64enc(req.userinfo))
    tinsert(lines, auth)
  end
  tinsert(lines,'\r\n')
  return tconcat(lines,'\r\n')
end

Then create connection like this (change API key):

Code:

ws = require('user.websocket')
json = require('json')

url = 'wss://door.casambi.com/v1/bridge/'

client, err = ws.client('sync', 10)
client.protocol = 'API-key'
res, err = client:connect(url)

log(res, err)

After making the changes in library, it throws the following error:-

User library websocket:292: attempt to index global 'self' (a nil value)
stack traceback:
User library websocket:292: in function 'upgrade_request'
User library websocket:462: in function 'connect'
