需要了解如何使用python刮取实时流数据的帮助

我正试着收集这个本地web服务器的当前使用情况。这个数字每秒更新一次由随机数生成器生成的值。

当前时间:07:25:16 UTC

当前日期:2018-11-28 UTC

电流使用:13kw

到目前为止,这就是我对美丽集团的尝试:

import requests
from bs4 import BeatifulSoup
import time

def get_count():
  url = "http://10.0.0.206/apps/cy8ckit_062_demo/main.html"

  # request with fake header, otherwise you will get an 403 HTTP error
  r = request.get(url, headers={'User-Agent': Mozilla/5.0})

while True:
  print(get_count())
  time.sleep(8)

但是,当我运行这个脚本时,我每8秒得到一个输出'none'

以下是Web服务器检查的输出:

当前时间:07:39:42 UTC

当前日期2018-11-28 UTC

电流使用:8kw

我一直在试着遵循这一点: How to scrape real time streaming data with Python?

这是我在尝试@chitown88代码后得到的输出:

Traceback (most recent call last):
  File "C:/seniord/csusite/readweb.py", line 14, in <module>
    soup = BeautifulSoup(r.text, 'html.parser')
NameError: name 'r' is not defined

在尝试了@chitown88中修改后的代码后,我将其作为输出(不显示动态值,但我认为beautifulsoup解决了这个问题):
