Pyhon Sokcet通讯的 不同类型的简单DEMO

1、使用socket模块进行TCP 通讯

服务端

#!/usr/bin/python
# -*- coding: utf-8 -*-

import socket

s = socket.socket()
#绑定地址和端口
s.bind(('127.0.0.1', 4455))
#监听指定数量客户端
s.listen(1)
#等待连接
#连接成功后，得到客户端的socket(conn)和地址(addr)
conn, addr = s.accept()

while True:
    print("Have New Connection!")
    request = conn.recv(1024)
    print(request)
    respone = raw_input("Input your name:")
    if respone == 'exit':
        break
    conn.sendall(respone)

s.close()

客户端

#!/usr/bin/python
# -*- coding: utf-8 -*-

import socket

s = socket.socket()
s.connect(('127.0.0.1', 4455))

while True:
    resquest = raw_input("Input your name:")
    s.sendall(resquest)
    respone = s.recv(1024)
    print(respone)

s.close()

2、使用socket模块进行UDP通讯

服务端

#!/usr/bin/python
# -*- coding: utf-8 -*-

import socket

#因为是UDP，所以类型要采用socket.SOCK_DGRAM
s = socket.socket(type=socket.SOCK_DGRAM)
s.bind(('127.0.0.1', 4455))
data, addr = s.recvfrom(1024)
print(data)
respone = raw_input("input your name:")
#UDP要使用sendto来进行通讯
s.sendto(respone,addr)
s.close()

客户端

#!/usr/bin/python
# -*- coding: utf-8 -*-

import socket
#因为是UDP，所以类型要采用socket.SOCK_DGRAM
s = socket.socket(type=socket.SOCK_DGRAM)
message = raw_input("input your name:")
#UDP需要使用sendto来进行消息发送
s.sendto(message,('127.0.0.1',4455))
#UDP要使用rescfrom来进行消息接收
data, addr = s.recvfrom(1024)
print(data)
s.close()

3、使用socketserver中的TCPserver模块进行TCP通讯

服务端

#!/usr/bin/python
# -*- coding: utf-8 -*-

from socketserver import TCPServer, StreamRequestHandler

host = '127.0.0.1'
port = 5566
addr = (host, port)

#自定义handler处理类
#继承自StreamRequestHandler
#重写handle方法

class MyHandler(StreamRequestHandler):
    def handle(self):
        print("The connect client is :", self.client_address)
        while True:
            data = self.request.recv(1024)
            print(data)
            respone = raw_input("input message:")
            self.request.sendall(respone)

#判断地址和handler处理类
tcpserver = TCPServer(addr, MyHandler)
#启动TCP服务
tcpserver.serve_forever()

客户端

#!/usr/bin/python
# -*- coding: utf-8 -*-

import socket

s = socket.socket()
s.connect(('127.0.0.1', 5566))
while True:
    data = raw_input("input message:")
    if data == 'exit':
        break
    s.sendall(data)
    respone = s.recv(1024)
    print(respone)
s.close()

4、使用socketserver中的UDPserver模块进行通讯 使用BaseRequestHandler进行数据传输

服务端

#!/usr/bin/python
# -*- coding: utf-8 -*-

from socketserver import UDPServer, BaseRequestHandler

host = '127.0.0.1'
port = 7777
addr = (host, port)


class MyHandler(BaseRequestHandler):
    def handle(self):
          
        #这里不同的是request是一个元组
        data = self.request
        #元组第一位为接收到的信息
        print(data[0])
        #元组的第二位为socket套接字
        conn = data[1]
        response = raw_input("Input your name:")
        conn.sendto(response, self.client_address)


udp = UDPServer(addr, MyHandler)
udp.serve_forever()

客户端

#!/usr/bin/python
# -*- coding: utf-8 -*-

import socket

host = '127.0.0.1'
port = 7777
addr = (host, port)

s = socket.socket(type=socket.SOCK_DGRAM)

while True:
    data = raw_input("Input your name:")
    if data == 'exit':
        break
    s.sendto(data, addr)
    respone = s.recvfrom(1024)
    print(respone[0])
s.close()

5、使用socketserver中的UDPserver模块进行通讯 使用DatagramRequestHandler进行数据传输

与4相比，使用DatagramRequestHandler中封装好的方法进行消息收发

服务端

#!/usr/bin/python
# -*- coding: utf-8 -*-

from socketserver import UDPServer, DatagramRequestHandler

host = '127.0.0.1'
port = 7777
addr = (host, port)


class MyHandler(DatagramRequestHandler):
    def handle(self):
        #使用rfile接收信息
        request = self.rfile.readlines()
        #request接收到的是一个数组，第一个是接收到的信息
        print(request[0])
        response = raw_input("Input your name:")
        #使用wfile发送信息
        self.wfile.writelines(response)


udp = UDPServer(addr, MyHandler)
udp.serve_forever()

客户端

#!/usr/bin/python
# -*- coding: utf-8 -*-

import socket

host = '127.0.0.1'
port = 7777
addr = (host, port)

s = socket.socket(type=socket.SOCK_DGRAM)

while True:
    data = raw_input("Input your name:")
    if data == 'exit':
        break
    s.sendto(data, addr)
    respone = s.recvfrom(1024)
    print(respone[0])
s.close()
