python - 属性错误 : 'NoneType' object has no attribute 'find'

Question

我必须通过网站上的搜索查询来搜索 CVE 或常见漏洞和暴露，然后在我的打印请求中打印导入结果表。我用来抓取结果的网站是 https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=CVE+2017

我正在使用 python 3 进行编码，并且是新手，想将其用作项目

import urllib.request
import urllib
searchStr = input("Enter Search Query \n")
r = urllib.request.urlopen("https://cve.mitre.org/cgi-bin/cvekey.cgi?
keyword="+searchStr)
source_code = r.read()
from bs4 import BeautifulSoup
soup = BeautifulSoup(source_code, 'html.parser')
table = soup.find('tbody', id = 'TableWithRules')
rows = table.find('tr')
for tr in rows:
    cols = tr.find('td')
    p = cols[0].text.strip()
    d = cols[1].text.strip
    print(p)
    print(d)

给我以下错误:

Traceback (most recent call last):
  File "C:\Users\Devanshu Misra\Desktop\Python\CVE_Search.py", line 9, in 
<module>
    rows = table.find('tr')
AttributeError: 'NoneType' object has no attribute 'find'

Answer 1

“正确”的答案不正确
这一行是错误的:

divtag=soup.find('div',{'id':'TableWithRules'})

应该是:

table=soup.find('div',{'id':'TableWithRules'})
