Python 初识socket---UDP发送数据

#发送数据



import socket


def main():
    #udp套接字对象
    udp_socket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)

    data = input("请输入要发送的数据")


    #发送数据   字符串前面是b
    #udp_socket.sendto(b"1234",("192.168.x.x", xxxx))

    udp_socket.sendto(data.encode("utf-8"), ("192.168.x.xxx", 8080))

    udp_socket.close()


if __name__ == '__main__':
    main()




#循环发送
import socket

def send(data):


    udp_socket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)


    udp_socket.sendto(data.encode("utf-8"),("192.168.x.xxx", xxxx))

    udp_socket.close()



if __name__ == '__main__':

    while True:
        data = input("input：")
        if data == "exit":
            break
        send(data)

# 先绑定端口再发送数据
import socket


def main():
    #udp套接字对象
    udp_socket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)

    udp_socket.bind(("", 7890))  # 绑定端口
    while True:

        data = input("请输入要发送的数据")


        #发送数据   字符串前面是b
        #udp_socket.sendto(b"1234",("192.168.1.114", 8080))

        udp_socket.sendto(data.encode("utf-8"), ("192.168.1.114", 8080))

    udp_socket.close()


if __name__ == '__main__':
    main()
