Python实现端口复用实例代码

例子2

import socket
tcp1 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
tcp2 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
#在绑定前调用setsockopt让套接字允许地址重用
tcp1.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
tcp2.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
 #接下来两个套接字都也可以绑定到同一个端口上
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)
#在绑定前调用setsockopt让套接字允许地址重用
tcp1.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
tcp2.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
 #接下来两个套接字都也可以绑定到同一个端口上
tcp1.bind(('0.0.0.0', 12345))
tcp2.bind(('0.0.0.0', 12345))
