Reading event notifications from Grandstream GDS3710 - tigi - 13.04.2023

I'm trying to setup event notification for the grandstream GDS3710.
I cannot use an lp script since the gds3710 only accepts an ip and port

I've searched the forum for a simple resident script which is able to capture the data the gds3710 sends when an event occurs but without any luck.
I've found a script which at least generates some output but not the whole body.

Code:
* string: POST / HTTP/1.1User-Agent: Wget/1.16.1 (linux-gnu)Accept: */*Accept-Encoding: identityHost: 192.x.x.x:7777Connection: Keep-AliveContent-Type: application/x-www-form-urlencodedContent-Length: 29

Can someone point me to the right direction or alter the script below.

Code:
local socket = require("socket")
local server = assert(socket.bind("*", 7777))
local header
while 1 do
  local client = server:accept()
  local line = client:receive()
  header = line
  while (#line > 0) do
    line = client:receive()
    header = header .. line
  end
  log(header)  
end

Thanks in advance!

Try this:

Code:
local socket = require("socket")
local server = assert(socket.bind("*", 7777))
local crlf = '\r\n'

while true do
  local client = server:accept()

  client:settimeout(5)

  local pat, len

  while true do
    local res, err = client:receive(pat)

    if err then
      break
    end

    if type(pat) == 'number' then
      client:send(
        'HTTP/1.1 200 OK' .. crlf ..
        'Connection: close' .. crlf .. crlf
      )

      log(res) -- contains request body

      break
    elseif #res == 0 then
      pat = len
    elseif not len then
      len = res:match('Content%-Length: (%d+)')
      len = tonumber(len)
    end
  end

  client:close()
end

Works as a charm!
Thank you very much admin! Cool
