POPython: Passing Multiple Variables Across TCP Client/Server
text
Body
copied!<p>I'm creating a TCP client and server using Python 3.3 and I'm new to using both Python and sockets. My issue is that I need to be able to store anything passed across the connection as a separate variable for writing to various files, etc. </p> <p>I'm unsure how to do this as it all seems to be one stream of data that I cannot store separately. Below is my latest piece of working code and all it does is send the data I need across the connection. Should I be trying to send all the data across as a list and de-construct it into separate variables? Can I already access them separately and I just haven't figured it out yet? Is my approach all wrong? </p> <p>Server code:</p> <pre><code>import os from socket import * HOST = '' #We are the host PORT = 29876 ADDR = (HOST, PORT) BUFFSIZE = 4096 serv = socket( AF_INET,SOCK_STREAM) serv.bind(ADDR,) #Create tuple with one element serv.listen(5) print ('listening...') conn,addr = serv.accept() print (conn,addr) print ('...connected') with open(os.path.expanduser("~/.ssh/id_rsa.pub")) as f: key = f.read() conn.sendall(key) print(key) while True: data = conn.recv(BUFFSIZE) print(data) conn.close() </code></pre> <p>Client code:</p> <pre><code>from socket import * import os import socket HOST = 'xxx.xxx.xxx.xxx' PORT = 29876 #Must match server.py ADDR = (HOST,PORT) BUFFSIZE = 4096 cli = socket.socket( AF_INET, SOCK_STREAM) cli.connect(ADDR,) s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) s.connect(("gmail.com",80)) ip = ((s.getsockname()[0])) ip = ip.encode('utf-8') cli.send(ip) while True: data = cli.recv(BUFFSIZE) print (data) cli.close() </code></pre>
