我在抓取某些页面时收到错误“urllib.error.HTTPError:HTTP Error 403:Forbidden”,并了解在标题中添加http
.authorizeRequests()
.antMatchers("/high_level_url_A/sub_level_1").hasRole('USER')
.antMatchers("/high_level_url_A/sub_level_2").hasRole('USER2')
.somethingElse() // for /high_level_url_A/**
.antMatchers("/high_level_url_A/**").authenticated()
.antMatchers("/high_level_url_B/sub_level_1").permitAll()
.antMatchers("/high_level_url_B/sub_level_2").hasRole('USER3')
.somethingElse() // for /high_level_url_B/**
.antMatchers("/high_level_url_B/**").authenticated()
.anyRequest().permitAll()
之类的内容就是解决此问题的方法。
但是,当我正在尝试抓取的URL位于单独的源文件中时,我无法使其正常工作。如何/在哪里可以将User-Agent添加到下面的代码中?
hdr = {"User-Agent': 'Mozilla/5.0"}
谢谢:)

您可以使用requests
import requests
hdrs = {'User-Agent': 'Mozilla / 5.0 (X11 Linux x86_64) AppleWebKit / 537.36 (KHTML, like Gecko) Chrome / 52.0.2743.116 Safari / 537.36'}
for url in line_in_list:
resp = requests.get(url, headers=hdrs)
soup = BeautifulSoup(resp.content, 'html.parser')
name = soup.find(attrs={'class': "name"})
description = soup.find(attrs={'class': "description"})
for text in description:
print(name.get_text(), ';', description.get_text())
# time.sleep(5)
i += 1
希望它有所帮助!
