我正试图将seekingalpha.com新闻部分作为一个个人项目。然而，我似乎无法成功地模拟浏览器，因为一旦我到达第8页左右，我就会得到403 forbidden output code。如果我以私人模式打开浏览器，我可以手动浏览所有页面，这样我的IP就不会被阻止。
我在Python3.8中使用Requests和Beautifulsoup
我有：
-
添加了合法的用户代理以及尝试的随机用户代理
-
使用应该自动更新cookie的请求会话，我相信(？(
-
添加了Referrer标头
- 请求之间的延迟增加
这是我的代码：
import requests
import time
import random
import webbrowser
from bs4 import BeautifulSoup
import re
import sys
import os
class SeekingAlpha():
from fake_useragent import UserAgent
ua = UserAgent()
BASE_URL = 'https://seekingalpha.com/'
NEWS_URL = BASE_URL + 'articles?page={}'
def __init__(self):
self.session = requests.Session()
self.session.headers['User-Agent'] = 'Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:52.0) Gecko/20100101 Firefox/52.0'
response =self.session.get(self.BASE_URL)
response.raise_for_status()
self.session.headers['Referrer'] = 'https://seekingalpha.com/'
print(self.session.headers)
self.master_urls = []
for i in range(1,100):
page = self.session.get(self.NEWS_URL.format(i))
time.sleep(random.randint(3,5))
page.raise_for_status()
soup = BeautifulSoup(page.content, 'html.parser')
links = soup.find_all('a', href = True)
links = [link for link in links if link.has_attr("sasource") and link['sasource'] == 'all_articles']
self.master_urls.extend(links)
if __name__ == "__main__":
master_urls = SeekingAlpha()

你试过增加随机睡眠吗？我认为3-5太低了，在你第8次请求后，网站可能会关闭你。要么增加它，要么如果你得了403，就去睡觉，过一段时间再试一次。
如果你真的需要尽快的数据，配置一个Tor代理，并使用它一段时间。(给你一个不同的外部IP-放弃你的会话以防万一(
有时，如果你的机器人太烦人，网站的所有者会把你赶出去(至少，这是我的经验：//(。
