udp__2">socket 发送udp 示例

import socket
import time# 初始化端口
self.ip_port = (host_msg,ip_port_msg)
# 创建 socket
self.client = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)  
# 发送
self.client.sendto(self.msg,self.ip_port)
# 关闭 soceket
self.client.close()

UDPServer 用于接收 UDP 示例

# 继承  UDPServer 
class MyUDPServer(UDPServer):def __init__(self, server_address, RequestHandlerClass, queue):# 传递用于接受的队列self.udp_queue = queue  # UDPServer 实例化           地址          服务函数UDPServer.__init__(self, server_address, RequestHandlerClass, bind_and_activate=True)class Handler(BaseRequestHandler):def handle(self):self.data = self.request[0].strip()self.server.udp_queue.put(self.data)

​

class my_udp_server():def __init__(self,udp_queue):super().__init__()# 创建用于接受的队列self.queue = udp_queue# 创建服务，def open_udp_server(self,ip,port):  ADDR = ip, port#实例化 MyUDPServer 类self.UDPServer = MyUDPServer(ADDR, Handler, self.queue)  #创建线程，将UDPServer的serve_forever  传递进线程成中self.server_thread = threading.Thread(target=self.UDPServer.serve_forever)  #设置后台线程self.server_thread.setDaemon(True) #启动线程self.server_thread.start()   def close_udp_server(self):  #服务  shutdownself.UDPServer.shutdown()#关闭服务self.UDPServer.server_close()# 创建 队列用于接收
self.udp_queue= Queue(maxsize=5)
# 实例化 udp 服务
self.udp_server = my_udp_server(self.udp_queue)
# 打开服务
self.udp_server.open_udp_server("192.168.1.100",6000)
# 关闭服务
self.udp_server.close_udp_server()
