大家好，���络连接和网速在工作中非常重要，本文将介绍如何使用Python程序来监测互联网连接的速度和中断情况。
（）1.导入所需库文件
首先，需要导入以下库：
import speedtestimport timefrom datetime import datetime
这里选择了第三方库speedtest-cli来执行实际的下载和上传速度测试。
（）2.创建循环变量
然后，创建一个名为i的变量，并将其值设为True。
i = True
这只是为了在主函数运行时保持循环，只要i为True，程序就会一直执行下去。
3.执行主要功能的函数
def run_prog(): print("Please wait while GPisc runs it's checks...\n") try: now = datetime.now() time_date = now.strftime("%d/%m/%Y %H:%M:%S") st = speedtest.Speedtest() server = st.get_best_server() server_location = server.get("name") host = server.get("host") dl_speed = st.download() ul_speed = st.upload() print(f'SERVER: {host} | LOCATION: {server_location}\n') with open('DL_LOG.txt', 'a') as log: log.writelines(f'{time_date} - DOWNLOAD SPEED: {dl_speed}\n') print(f'DOWNLOAD SPEED: {dl_speed}\n') with open('UL_LOG.txt', 'a') as log: log.writelines(f'{time_date} - UPLOAD SPEED: {ul_speed}\n') print(f'UPLOAD SPEED: {ul_speed}\n') except: with open('NO_NET_LOG.txt', 'a') as log: now = datetime.now() time_date = now.strftime("%d/%m/%Y %H:%M:%S") log.writelines(f'{time_date} - CONNECTION LOST!\n') print('CONNECTION LOST!\n') 上述代码是执行所有工作的函数。run_prog函数通过选择测试时的最佳服务器来运行下载和上传速度测试，然后将结果记录在3个.txt文件中 - DL_LOG.txt、UL_LOG.txt和NO_NET_LOG.txt。
4.结果记录和日志
日志中的数据如下所示：
05/08/2022 23:18:52 - DOWNLOAD SPEED: 51351410.3696997205/08/2022 23:20:14 - DOWNLOAD SPEED: 54115624.47745725505/08/2022 23:21:31 - DOWNLOAD SPEED: 50422315.8370637905/08/2022 23:22:53 - DOWNLOAD SPEED: 48712675.77967203405/08/2022 23:18:52 - UPLOAD SPEED: 34615688.5653379805/08/2022 23:20:14 - UPLOAD SPEED: 14661625.76618496105/08/2022 23:21:31 - UPLOAD SPEED: 36268210.7666829905/08/2022 23:22:53 - UPLOAD SPEED: 34678387.9505297225/07/2022 21:17:30 - CONNECTION LOST!25/07/2022 21:18:30 - CONNECTION LOST!25/07/2022 21:19:31 - CONNECTION LOST!25/07/2022 21:20:28 - CONNECTION LOST!
如上所示，这里没有将字节结果转换为Mbps，因为希望结果尽可能准确。如果需要，可以使用hurry.filesize 0.9（https://pypi.org/project/hurry.filesize/）来进行转换。
run_prog函数使用try和except来捕获除了速度结果之外的任何内容，这显然是没有连接的情况，因为如果无法连接到速度测试服务器，程序将失败，然后写入无连接日志。
while i: run_prog() time.sleep(60) print('**********************************************\n') 上述代码执行run_prog函数，然后等待60秒再次运行（这就是为什么创建了i = True）。
程序在每次执行测试时都会在控制台打印输出。
5.主函数循环
以下是完整的脚本:
import speedtestimport timefrom datetime import datetimei = Truedef run_prog(): print("Please wait while GPisc runs it's checks...\n") try: now = datetime.now() time_date = now.strftime("%d/%m/%Y %H:%M:%S") st = speedtest.Speedtest() server = st.get_best_server() server_location = server.get("name") host = server.get("host") dl_speed = st.download() ul_speed = st.upload() print(f'SERVER: {host} | LOCATION: {server_location}\n') with open('DL_LOG.txt', 'a') as log: log.writelines(f'{time_date} - DOWNLOAD SPEED: {dl_speed}\n') print(f'DOWNLOAD SPEED: {dl_speed}\n') with open('UL_LOG.txt', 'a') as log: log.writelines(f'{time_date} - UPLOAD SPEED: {ul_speed}\n') print(f'UPLOAD SPEED: {ul_speed}\n') except: with open('NO_NET_LOG.txt', 'a') as log: now = datetime.now() time_date = now.strftime("%d/%m/%Y %H:%M:%S") log.writelines(f'{time_date} - CONNECTION LOST!\n') print('CONNECTION LOST!\n')while i: run_prog() time.sleep(60) print('**********************************************\n')
