聊天器靈活版

上面實(shí)現(xiàn)的聊天雖然可以使用，但是不太方便，我們希望是發(fā)送消息還是接受消息，可以自己選擇，這樣就方便的多。如下的程序運(yùn)行輸入三個(gè)命令來選擇要執(zhí)行的操作，程序如下：

•1表示發(fā)送數(shù)據(jù)
•2表示接收數(shù)據(jù)
•0表示退出

import socket
def send_message(udp_socket):
    # 輸入對(duì)方的ip/port
    dest_ip = input("請(qǐng)輸入對(duì)方的ip：")
    dest_port = int(input("請(qǐng)輸入對(duì)象的port："))
    # 讀取輸入的數(shù)據(jù)
    send_data = input('請(qǐng)輸入要發(fā)送的數(shù)據(jù)：')
    # 發(fā)送數(shù)據(jù)
    dest_addr = (dest_ip, dest_port)
    udp_socket.sendto(send_data.encode('GBK'), dest_addr)
def recv_message(udp_socket):
    # 接收數(shù)據(jù)
    recv_data = udp_socket.recvfrom(1000)
    print("%s:%s" % (recv_data[1], recv_data[0].decode("utf-8")))  
def main():
    # 創(chuàng)建套接字
    udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    while True:
        op = input("請(qǐng)輸入您要執(zhí)行的操作：")
        if op == "1":
            send_message(udp_socket)
        elif op == "2":
            recv_message(udp_socket)
        elif op == "0":
            break
        else:
            print("您的輸入有誤！")
    # 關(guān)閉
