http request - Angeles - 21.10.2019

Hi:

I'm trying to extract data from Mitsubishi Web Server - SC-SL4

The data to request is:

mensaje = ='<Packet> \r\n' ..
<Command>getRequest</Command> \r\n' ..
<AirConditioner> \r\n' ..
<OpGroup GrNo="1" OnOff="*" Mode="*" ErrorStatus="*"></OpGroup>\r\n' ..
</AirConditioner> \r\n' ..
</Packet>\r\n' ..

The server response 'error 400: syntax error

This is my code:

Content = string.len(mensaje)
soap = '<?xml version="1.0" encoding="UTF-8"?>'

-- http request
reqs = 'POST /servlet/MIMEReceiveServlet.asp HTTP/1.1\r\n'..
'Content-Type: text/xml\r\n'..
'Content-Length: '..Content..'\r\n' ..
'\r\n' ..
soap..'\r\n' ..mensaje

sock = socket.tcp()
sock Confused

ettimeout(70)

res, err = sock:connect(ip, port)
log(res,err)

if res then
res, err = sock Confused

end(reqs)

if res then
log('send OK ')
else
log('send failed: ' .. tostring(err))
end
else
log('connect failed: ' .. tostring(err))
end

res2, err2 = sock:receive("*a")
sock:close()

log(res2,err2)

The result is nil. We have another installation with another server and LMReactor and it works perfectly.

In this isntallation we have is with LMAmbient

Try this, your content-length header does not include initial XML line.
Edit: you are missing Host and Connection headers.

Code:
data = 
'<?xml version="1.0" encoding="UTF-8"?>\r\n' ..
'<Packet>\r\n' ..
'<Command>getRequest</Command>\r\n' ..
'<AirConditioner>\r\n' ..
'<OpGroup GrNo="1" OnOff="*" Mode="*" ErrorStatus="*"></OpGroup>\r\n' ..
'</AirConditioner>\r\n' ..
'</Packet>'

-- http request  
reqs = 'POST /servlet/MIMEReceiveServlet.asp HTTP/1.1\r\n'.. 
'Content-Type: text/xml\r\n'..
'Host: ' .. ip .. '\r\n' ..
'Connection: close\r\n' ..
'Content-Length: '.. #data..'\r\n\r\n' ..
data

sock = socket.tcp()
sock:settimeout(70)

res, err = sock:connect(ip, port)
log(res,err)

if res then
  res, err = sock:send(reqs)

  if res then
    log('send OK')
    
    res2, err2 = sock:receive("*a")
    sock:close()

    log(res2,err2)
  else
    log('send failed: ' .. tostring(err))
  end
else
  log('connect failed: ' .. tostring(err))
end

sorry I know that it's necessary include the HOST with HTTP/1.1, I tried everything and I have transcribed it badly.
The xml line is in soap variable.
