python网络编程实例简析,python编程实例简析

本文实例讲述了python网络编程,分享给大家供大家参考。

具体方法如下:

服务端代码如下:

from SocketServer import(TCPServer as TCP, 
             StreamRequestHandler as SRH) 
from time import ctime 

HOST = '' 
PORT = 21567 
ADDR = (HOST, PORT) 
class MyRequestHandle(SRH): 
  def handle(self): 
    print 'connecting from ..', self.client_address 
    self.wfile.write("[%s]:%s" %  
             (ctime(),self.rfile.readline()) 
             ) 
tcp_Server = TCP(ADDR,MyRequestHandle) 
print 'WAITING connecting...' 
tcp_Server.serve_forever() 

客户端代码如下:

from socket import * 

HOST = 'localhost' 
PORT = 21567 
BUFSIZE = 1024 
ADDR = (HOST, PORT) 

while True: 
  tcpCliSock = socket(AF_INET,SOCK_STREAM) 
  tcpCliSock.connect(ADDR) 
  data = raw_input('>>>') 
  if not data: 
    break 
  tcpCliSock.send("%srn" % data) 
  data = tcpCliSock.recv(BUFSIZE) 
  if not data: 
    break 
  print data.strip() 
  tcpCliSock.close() 

希望本文所述对大家的Python程序设计有所帮助。

Python简单网络编程示例【客户端与服务端】,python网络编程示例

本文实例讲述了Python简单网络编程。分享给大家供大家参考,具体如下:

电子游戏平台,内容目录

  1. 客户端(client.py)
  2. 服务端(server.py)

一、客户端(client.py)

import socket
import sys
port = 70
host = sys.argv[1]
filename = sys.argv[2]
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, port))
fd = s.makefile("rw", 0)
fd.write(filename + "n")
for line in fd.readlines():
  sys.stdout.write(line)

程序通过socket.socket()建立一个Socket,参数告诉系统需要一个Internet
Socket进行TCP通信。接着程序链接远程的主机名,并提供文件名。最后获得响应后在屏幕上打印出来。

二、服务端(server.py)

# coding: utf-8
import socket
host = ''
port = 51421
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind((host, port))
s.listen(1)        #每次最多只有一个等候处理
print "Server is running on port %d; press Ctrl-C to terminate." %port
while 1:
  clientsock, clientaddr = s.accept()
  clientfile = clientsock.makefile('rw', 0)
  clientfile.write("Welcome, " + str(clientaddr) + "n")
  clientfile.write("Please enter a string: ")
  line = clientfile.readline().strip()
  clientfile.write("You entered %d characters. n" %len(line))
  clientfile.close()
  clientsock.close()

建立一个socket,设置成可复用的(reusable),绑定端口号51421(可选大于1024的任一值),调用listen()函数,开始等待来自客户端的请求,同时设定最多只有一个等候处理的链接。

主循环对a.accept()函数调用开始,程序连接一个客户端后立马停止,接收用户的输入。

运行一个例子

首先运行server.py

python server.py

另开一个终端,连接localhost的51421端口。 

[email protected]:~/web$ telnet localhost 51421
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Welcome, ('127.0.0.1', 59853)
Please enter a string: mm
You entered 2 characters.
Connection closed by foreign host.

你好,可以不可以给些PYTHON网络编程的资料或例程?

取下在个twisted的电子书。
如果只是简单的socket编程,找些博客文章就行了!
 

python socket 编程疑问

你的例子没问题啊
while 1:
这一段就是一个infinite loop阿
只要client(就是浏览器)和server(就是你的程序)仍然有通信,while循环就不结束

所以你看到的就是卡住的效果,其实是因为server一直等着接收client发的数据

所以只有你强制关掉server程序,这个while循环才退出。

通常,如果你要发送很长的请求到server,是需要某种方法表示出你的数据的长度,一种是Unique
End-of-string Identifier (就是字符串结束标记,在数据尾部),一种是 Size
Indicator(在数据开始时告诉server你的数据有多长)

建议你仔细看下相关的文档或书拉,这里很难解释清楚。
