Web抓取导致403禁止错误
问题内容：
我正在尝试使用BeautifulSoup从SeekingAlpha网站上抓取每家公司的收益。但是，似乎该站点正在检测到正在使用Web刮板？我收到“
HTTP错误403：禁止访问”
我尝试抓取的页面是：https :
//seekingalpha.com/symbol/AMAT/earnings
有谁知道该怎么做才能绕过这个？
问题答案：
我可以使用从这里找到的代理访问网站内容：
然后，使用该requests模块创建播放负载，即可抓取该网站：
import requests
import re
from bs4 import BeautifulSoup as soup
r = requests.get('https://seekingalpha.com/symbol/AMAT/earnings', proxies={'http':'50.207.31.221:80'}).text
results = re.findall('Revenue of \$[a-zA-Z0-9\.]+', r)
s = soup(r, 'lxml')
titles = list(map(lambda x:x.text, s.find_all('span', {'class':'title-period'})))
epas = list(map(lambda x:x.text, s.find_all('span', {'class':'eps'})))
deciding = list(map(lambda x:x.text, s.find_all('span', {'class':re.compile('green|red')})))
results = list(map(list, zip(titles, epas, results, epas)))
输出：
