python 模拟udp客户端发送报文

import socket

target_host = "xxxxx"
target_port = 7777

# 建立一个socket对象

def send_udp(data):
    # 建立一个socket对象
    client = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

    # 发送一些数据
    response = client.sendto((data).encode(),(target_host.encode(),target_port))

    print(response)

    # 接收一些数据
    data, addr = client.recvfrom(4096)

    print(data)

if __name__ == '__main__':
    data="abcdefg"
    send_udp(data)
