Socket - send message

[Bierny]

Hi,
I would like to write a script which will connect to a server. I know I have to set up a tcp connection and after that send a registration message which consists of tag, length and value fields. All fields are bytes.
I have found a package "struct" which translates string to binary format but unfortunatelly I do not see appropriate format.

How can i do that?

Thanks in advance for any help/hints!

Best regards,

Hi,
Ok, I found it :-)

Let's say i want to send a message with following bytes "00201":

import struct

msg = struct.pack("!bbbbb", 0, 0, 2, 0, 1)
mySocket.send(msg)

...

and later in order to unpack a received message:

unpacked_msg = struct.unpack

That should work ;-)

Best regards,
