I have a project in PYTHON that is two machines (A , B) , 1) request machine A send a request to B to list a directory(in my code i set it to current directory) 2) in second request machine A wants to download the Text file of the directory. (Put a text file in machine B's directory) 3) after that machine A changes the text file and send back to the machine B. 4) and At the end machine A send two number and machine B send back the result of it. it work till step 2 but nothing happen after that it's like a true while I can't understand why?! Here is my Code Machine A (Client):
# -*- coding: UTF-8 -*-
import os
import socket
PORT = 9000
HOST = 'localhost'
socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket.connect((HOST, PORT))
store=[]
direc = raw_input("Enter The Directory to List : ")
socket.sendall(direc)
len_data = socket.recv(2048)
print int(len_data)
for i in range(int(len_data)):
data = socket.recv(2048)
store.append(data)
print("List of Files:")
for i in store:
print(i)
txt_file = raw_input("Please Choose a TEXT file :")
if store.count(txt_file) is 0:
print("There no such a TXT file!!")
else:
socket.sendall(txt_file)
def write_file(name):
fname = open(name,'ab')
while True:
string = socket.recv(2048)
if string:
fname.write(string)
else:
fname.write("changed")
fname.close()
break
def read_file(name):
fileToSend = open(name, 'rb')
while True:
data = fileToSend.readline()
if data:
socket.send(data)
else:
fileToSend.close()
break
write_file(txt_file)
read_file(txt_file)
x = raw_input("Enter The First Num: ")
socket.send(x)
y = raw_input("Enter The Second Num: ")
socket.send(y)
result = socket.recv(1024)
print result
raw_input()
socket.sendall('')
socket.close()
exit()
and the Machine B (Server):
import os,sys,socket
PORT = 9000
HOST = 'localhost'
tcpsocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = (HOST, PORT)
print >>sys.stderr, 'starting up on %s port %s' % server_address
socket.bind((HOST,PORT))
socket.listen(1)
conn, addr = socket.accept()
directory = conn.recv(2048)
if os.listdir(os.curdir):
data = os.listdir(os.curdir)
len_data = data.__len__()
print(len_data)
if len_data:
conn.send(str(len_data))
for i in data:
if i:
print >>sys.stderr, 'sending data back to the client'
conn.send(i)
else:
break
txt_file_name = conn.recv(2048)
def write_file(name):
with open(name,'wb') as fname:
while True:
string = conn.recv(2048)
if string:
fname.write(string)
else:
fname.close()
break
def read_file(name):
with open(name, 'rb') as fileToSend:
while True:
data = fileToSend.readline()
if data:
conn.send(data)
else:
fileToSend.close()
break
def add (x,y):
return str(x+y)
read_file(txt_file_name)
write_file(txt_file_name)
x = conn.recv(1024)
y = conn.recv(1024)
conn.send(add(x,y))
conn.sendall('')
conn.close()
exit()
