使用PythonSocket编程详解

这篇文章主要介绍了Python Socket编程详细介绍，socket可以建立连接，传递数据，具有一定的参考价值，感兴趣的小伙伴们可以参考一下。

import pickle

class SocketServer(object):

    sock_server.bind(('0.0.0.0', self.port))
    sock_server.listen(0)

    while True:
      sock, address = sock_server.accept()
      thread.start_new_thread(self.__invoke, (sock, address))

          response = SimpleRequestHandler().handle(request)
          sock.sendall(pickle.dumps(response) + EOF)
          return
    except Exception as e:
      print e
    finally:

class SocketClient(object):

  def __init__(self, host, port):
    self.host = host
    self.port = port

  def execute(self, request):
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock.connect((self.host, self.port))

    try:

      while True:

class SocketRequest(object):
  def __init__(self, data):
    self.data = data

  def __repr__(self):
    return repr(self.__dict__)


class SocketResponse(object):
  def __init__(self, data):

  def __repr__(self):
    return repr(self.__dict__)


class SimpleRequestHandler(object):
  def __init__(self):
    pass

  def __repr__(self):
    return repr(self.__dict__)

  def handle(self, request):
    return SocketResponse(request.data) 

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from agent.sockets import *

ss = SocketServer(PORT)
ss.startup() 

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import pickle
from agent.sockets import *


sc = SocketClient('localhost', PORT)
request = SocketRequest('abc')
response = sc.execute(request)
print request
print response 

运行测试

首先，运行 socket_server.py

然后，运行 socket_client.py
