my socket class: getting a strange error regarding my methods
okay, so the code is below. when i run it coupled with the following test code, I get the following error.
PHP Code:
import socket
class NewSock:
"a class intended to simplify socket programming"
# derived from the class in the HOWTO documents
def __init__( self , sock = None ):
if sock is None:
self.sock = socket.socket( socket.AF_INET , socket.SOCK_STREAM )
else:
self.sock = sock
def connect( host , port ):
try:
self.sock.connect( ( host , port ) )
except error:
return 0
return 1
def bind( host , port ):
try:
self.sock.bind( ( host , port ) )
except error:
return 0
return 1
def run():
self.sock.listen(5)
self.conn , self.addr = self.sock.accept()
# i know this doesn't do anything yet, i'm going to
# implement threads as soon as i get this class
# working
def send( data ):
datlen = len( data )
totalsent = 0
while totalsent < datlen:
sent = self.conn.send( msg[totalsent:] )
if sent == 0:
return 0;
totalsent += sent
else:
return 1
def recv():
'''
okay, so the first recv() loop is meant to gather the initial data,
which will be an integer that tells the second recv() loop how much
data to expect this time around. prebytsz hold this, and the \n
tells the first loop when they have aquired the byte size. for example:
"45\nthismessageisaslongasthenumberbeforethereturn"
for this reason, i take the data byte by byte, waiting for the \n.
then i transfer the data over to the variable "remaining", minus the
last character which, ideally, is a \n, where it is converted to an
integer. as data comes in their len()s are subtracted from remaining,
until its all gone. sounds good on paper, but will it work?
'''
prebytsz = ''
while prebytsz[0:len( prebytsz )] != "\n":
prebytsz += self.conn.recv( 1 )
else:
if prebytsz[0:len( prebytsz )] is "\n":
data = ''
remaining = int( prebytsz[ 0 : len( prebytsz ) - 1 ] )
while len( data ) < remaining:
data += self.conn.recv( 1024 )
remaining -= len( data )
return data
else:
return 0
PHP Code:
sock = NewSock
sock.bind( 'localhost' , 5376 )
sock.run()
sock.send( "I HATE YOU: " + sock.recv() )
Code:
Traceback (most recent call last):
File "C:\Documents and Settings\Daniel\Desktop\python\class_socket.py", line 67, in ?
sock.bind( 'localhost' , 5376 )
TypeError: unbound method bind() must be called with NewSock instance as first argument (got str instance instead)
I'm not sure what to do, at all, could someone help? Thanks.
