How to implement a custom binary protocol using these rules?

QUESTION

How to implement a custom binary protocol using these rules?

Asked 2019-Sep-16 at 18:14

I am trying to send binary data to a server that gives me back a response on doing so. The rules seems understandable to someone who is familiar with python but I am new to python and socket programming using struct. So the documentation states this:

There is an 8 byte header that has a 32 bit integer for the request tag and a 32 bit integer for the command. The type is uint32. The buffersize depends on the type of command.

Some commands take arguments and they are sent in tandem with the command message header directly after the header with no padding. The size of the arguments buffer is dictated by the command type.

So I connected to the server and now I tried to package to values and send it like that but I dont know if I am doing it right.

...

ANSWER

Answered 2019-Sep-16 at 18:14

Ok so I found the errror and was able to get the response I wanted with the server. The error was with

packer = struct.Struct('i i ') // Needed to format it like ('! i i')

and raw_data = sock.recv(1024) unpacked_data = struct.unpack('>i i', raw_data) // Needed to add ! not > print(unpacked_data) sock.close()

also I wrote a simple unpacker that helped me to unpack it the proper way

def data_unpacking(data): tag, code = struct.unpack('!ii', data[:8]) return tag, code, data[8:]

then called the function in main with the parameter raw_data
