python - python请求问题：cloudflare错误消息“启用cookies”

问题描述

我正计划为 Sneakersnstuff.com 网站创建一个基本的网络爬虫，但由于一个错误，我的努力提前停止了。当向 url https://www.sneakersnstuff.com/请求时，而不是显示网站的 html，甚至是入口验证码，我被重定向到带有错误消息“启用 cookie”的 cloudflare 页面。我的代码和响应都如下所示

import requests
import cfscrape


session = requests.session()

response = session.get('https://www.sneakersnstuff.com/')

print(response.headers)

我曾尝试使用许多名为 cfscrape 的库推荐，但无济于事。

解决方案

添加Browser/User-Agent Filtering到 cloudcraper 对我有用。

import cloudscraper
from bs4 import BeautifulSoup

# Adding Browser / User-Agent Filtering should help ie. 

# will give you only desktop firefox User-Agents on Windows
scraper = cloudscraper.create_scraper(browser={'browser': 'firefox','platform': 'windows','mobile': False})

html = scraper.get("https://www.sneakersnstuff.com/").content

soup = BeautifulSoup(html, 'html.parser')

print(soup)
