如何在python中将消息从客户端发送到服务器

问题描述

我正在阅读Python2.7.10中具有客户端和服务器的两个程序。如何修改这些程序以将邮件从客户端发送到服务器？

server.py：

#!/usr/bin/python           # This is server.py file

import socket               # Import socket module

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345                # Reserve a port for your service.
s.bind((host, port))        # Bind to the port

s.listen(5)                 # Now wait for client connection.
while True:
   c, addr = s.accept()     # Establish connection with client.
   print 'Got connection from', addr
   c.send('Thank you for connecting')
   c.close()                # Close the connection

client.py：

#!/usr/bin/python           # This is client.py file

import socket               # Import socket module

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 80              # Reserve a port for your service.

s.connect((host, port))
print s.recv(1024)
s.close                     # Close the socket when done

解决方案

套接字是双向的。所以连接后，服务器和客户端没有区别，只有流的两端：

import socket               # Import socket module

s = socket.socket()         # Create a socket object
s.bind(('0.0.0.0', 12345))        # Bind to the port

s.listen(5)                 # Now wait for client connection.
while True:
   c, addr = s.accept()     # Establish connection with client.
   print 'Got connection from', addr
   print c.recv(1024)
   c.close()                # Close the connection

和客户端：

import socket               # Import socket module

s = socket.socket()         # Create a socket object
s.connect(('localhost', 12345))
s.sendall('Here I am!')
s.close()                     # Close the socket when done
