本文介紹Python實現端口復用實例如下所示：
#coding=utf-8
import socket
import sys
import select
import threading
host='192.168.99.100'
port=80
class Thread(threading.Thread):
def __init__(self,buf,sockfd):
threading.Thread.__init__(self)
self.buf=buf
self.sockfd=sockfd
def run(self):
if len(self.buf)!=0:
if 'GET' in self.buf : #判斷是否是瀏覽器提交的數據如果是則將提交的數據轉發至本地環回地址的80端口
s2=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s2.connect(('127.0.0.1',80))
s2.send(self.buf)
bufer=''
while 1:
recv_data=s2.recv(1024)
bufer+=recv_data
if len(recv_data)==0:
break
print bufer,len(bufer)
if len(bufer)==0:
pass
self.sockfd.send(bufer) #將服務器發送的數據發回客戶端
s2.close
self.sockfd.close
sys.exit()
else:
'ps:connect to ssh' #如果數據不是瀏覽器提交則將其轉發至本地的22端口
s2=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s2.connect(('127.0.0.1',22))
s2.send(self.buf)
recv_data=s2.recv(4096)
conn.send(recv_data)
self.sockfd.close
s2.close
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.setsockopt( socket.SOL_SOCKET, socket.SO_REUSEADDR, 1 ) #端口復用的關鍵點
s.bind((host,port))
s.listen(10)
while 1:
infds,outfds,errfds=select.select([s,],[],[],5) #使用select函數進行非阻塞操作
if len(infds)!=0:
conn,(addr,port)=s.accept()
print 'connected by',addr,port
data=conn.recv(1024)
t=Thread(data,conn)
t.start()
s.close
#coding=utf-8
import socket
import sys
import select
import threading

例子2
import socket
tcp1 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
tcp2 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
#在綁定前調用setsockopt讓套接字允許地址重用
tcp1.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
tcp2.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
#接下來兩個套接字都也可以綁定到同一個端口上
tcp1.bind(('0.0.0.0', 12345))
tcp2.bind(('0.0.0.0', 12345))
import socket
tcp1 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
tcp2 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
#在綁定前調用setsockopt讓套接字允許地址重用
tcp1.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
tcp2.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
#接下來兩個套接字都也可以綁定到同一個端口上
tcp1.bind(('0.0.0.0', 12345))
tcp2.bind(('0.0.0.0', 12345))
