Python way to implement Scoket communication

To understand this network communication is really inseparable from the implementation of the flowchart, see the general many know, think this Bo master painting is good, the address is

1. Understand which layer it is in the transmission

2. Understanding its implementation flowchart

So, we can summarize his way of implementation and logic, the code is as follows

Server-side request 1. Create object 2. Bind the socket to the specified address, socket.bing (address) 3.3rd, after binding, the socket must be prepared, and the port is monitored Socket.listen 4. The Accept method of the socket waits for a client to request a connection 5. Processing Phase 6. The server calls the Close method of the socket to close the connection # server  import socket  address = (' 127.0.0.1 ', 31500)  s = socket.socket (socket.af_inet, socket. SOCK_STREAM) # s = Socket.socket ()  s.bind (address)  S.listen (5)  ss, addr = s.accept ()  print ' This is Server ', addr  ss.send (' server ')  RA = ss.recv (+)  print ra  ss.close ()  s.close ()  

　　

Client creation steps: 1. Create a socket connection server 2. Connect to Server Socket.connect ((host,port)) 3 using the Connect method of the socket. Customers and servers communicate via send and Recv methods 4. Call the Close method of the socket to communicate import socket    address = (' 127.0.0.1 ', 31500)  s = Socket.socket ( Socket.af_inet, Socket. SOCK_STREAM)  s.connect (address)    data = S.RECV (+)  print ' This is client ', Data    s.send (' client ')    S.close ()
