Question

我有以下用于网页抓取的Python代码，当我尝试运行此代码时，它会抛出以下错误。代码：

import lxml.html
import requests
from bs4 import BeautifulSoup

url1='http://stats.espncricinfo.com/ci/engine/stats/index.html?class=11;filter=advanced;orderby=runs;'
url2 ='page='
url3 ='size=200;template=results;type=batting'
url5 = ['http://stats.espncricinfo.com/ci/engine/stats/index.html?class=11;filter=advanced;orderby=runs;size=200;template=results;type=batting']
for i in range(2,3854):
     url4 = url1 + url2 + str(i) + ';' + url3
     url5.append(url4)
for page in url5:
        source_code = requests.get(page, verify=False)
    # just get the code, no headers or anything
        plain_text = source_code.text
    # BeautifulSoup objects can be sorted through easy
        soup = BeautifulSoup(plain_text, "lxml")
        for link in soup.findAll('a', {'class': 'data-link'}):
                href = "https://www.espncricinfo.com" + link.get('href')
                title = link.string  # just the text, not the HTML
                source_code = requests.get(href)
                plain_text = source_code.text
                soup = BeautifulSoup(plain_text, "lxml")
# if you want to gather information from that page
                for item_name in soup.findAll('span', {'class': 'ciPlayerinformationtxt'}):
                             print(item_name.string)

错误：

Answer 1

这是由于您要抓取的网站上的https证书配置错误造成的。作为解决方法，您可以在requests库

中关闭证书检查

requests.get(href, verify=False)

请注意，使用敏感信息时不建议您这样做。
