[网络协议]python socket UDP收发包

UDP发送端代码 创建socket、(绑定)、发送

import socket
client = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
#client.bind(("192.168.1.128", 8000))
msg = 'a' * 1024
while True:
    client.sendto(msg.encode(),('',8080))
    #data, server_addr = client.recvfrom(1024)#接收
    #print(data.decode('utf-8'))

接收端 创建socket、绑定建通端口、接收

import socket
server = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
server.bind(('127.0.0.1', 8080))
timestamps = []
while True:
    data, client_addr = server.recvfrom(1024)
    timestamps.append(time.perf_counter()) # 记录时间戳
    print('收到客户端发来的udp消息%s' % data.decode('utf-8'))
    #server.sendto(data.upper(), client_addr)  # 发送回去
