python实现建立udp通信

实现代码如下：

#udp协议通信
import socket,time
class UdpConnect:
    def get_udp(self,ip,port,message):
        #建立udp连接
        mysocket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        mysocket.connect((ip, port))
        #发送数据包并关闭连接
        mysocket.send(message.encode('GBK'))
        mysocket.close()
if __name__ == '__main__':
    ip='localhost'
    port=554
    # 拼接消息体，满足软件的协议规则（以下举例）
    packetId = str(time.time())
    name = "badbadboy"
    host = 'MyHostName'
    command = str(0x00000020)
    content = 'hello world'
    message = '1.0:' + packetId + ':' + name + ":" + host + ':' + command + ":" + content
    UdpConnect().get_udp(ip,port,message)
