使用python监测网络连接和网速的实现代码
作者:python慕遥
大家好,网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 speedtest import time from 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: 51351410.36969972
05/08/2022 23:20:14 - DOWNLOAD SPEED: 54115624.477457255
05/08/2022 23:21:31 - DOWNLOAD SPEED: 50422315.83706379
05/08/2022 23:22:53 - DOWNLOAD SPEED: 48712675.779672034
05/08/2022 23:18:52 - UPLOAD SPEED: 34615688.56533798
05/08/2022 23:20:14 - UPLOAD SPEED: 14661625.766184961
05/08/2022 23:21:31 - UPLOAD SPEED: 36268210.76668299
05/08/2022 23:22:53 - UPLOAD SPEED: 34678387.95052972
25/07/2022 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 speedtest import time from datetime import datetime i = True 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') while i: run_prog() time.sleep(60) print('**********************************************\n')
