Hi, I'm implementing a python client connecting to a C-backend server and am currently stuck to as to how to proceed with receiving variable-length byte stream coming in from the server.
I have coded the first 4 bytes (in hexadecimal) of message coming in from the server to specify the length of the message payload i.e. 0xad{...} I've managed to receive and translate the message length until I reach my second recv which I readjusted the buffer size to include the new message length. However that failed and recv received 0 bytes. I implemented the same algorithm on the server side using C and it work so appreciate if you can help me on this. # receive message length print 'receiving data' mlen = sock.recv(4) try: nbuf = int(mlen, 16) except ValueError as e: print 'invalid length type' return -1 while True: buf = sock.recv(nbuf) if not buf: break slen = len(buf) str = "{0} bytes received: {1}".format(slen, buf) print str -- http://mail.python.org/mailman/listinfo/python-list
