Convert file into string then Rebuild that String and make it a file again

Question

I want to send files over the network, however all the tools and commands that was proposed to me wont allow me to automate the process.

Now I remember there's a function in java which allows you to convert the file into json base64 string, then this string will be sent over the network, then the machine that will receive this will rebuild this into file.

I wonder if I could do that kind of stuff in python?

Any ideas? Thanks!

Answer 1

well, reading a file and writing a file are easy:

#read from a file
with open("path/to/file", "rb") as read_file:
    contents = read_file.read()
#write to a file
with open("path/to/file", "wb") as write_file:
    write_file.write(contents)

and for base64 encoding, look at the python docs

sending data over a connection is simple enough, and you can do it in many methods - i am not going to solve it here, but i will give you a list of methods you can use:

• the python socket module, doc
• another post about data: (Python) Send structured packet over network

here is an example using socket from http://wiki.python.org/moin/TcpCommunication

import socket

TCP_IP = '127.0.0.1'
TCP_PORT = 5005
BUFFER_SIZE = 1024
MESSAGE = "Hello, World!"

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((TCP_IP, TCP_PORT))
s.send(MESSAGE)
data = s.recv(BUFFER_SIZE)
s.close()

print "received data:", data
