python socket发送消息的方法

# FileName: client.py

import socket

import pandas as pd

port = 8001  # 端口和上面一致

host = "localhost"  # 服务器IP，这里服务器和客户端IP同一个

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

for i in range(10):

    sock.sendto(("Successful! Message %s! " % i).encode(), (host, port))

    port = 8001

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

    sock.bind(("", port))  # 从给定的端口，从任何发送者，接收UDP数据报

    print("Waiting for the port", port)

    while True:

        data, address = sock.recvfrom(1024)  # 接收一个报文为1024字节的数据报

        print("Received:", data.decode(), "from", address)

        if data.decode() == 'over':
