cloudcraper.exceptions.CloudflareChallengeError:檢測到Cloudflare版本2驗證碼挑戰

2022-11-09 10:36:54 後端開發

主檔案

import cloudscraper

scraper = cloudscraper.create_scraper()
cs_recent_page = scraper.get('https://coinsniper.net/new').text

錯誤

cloudscraper.exceptions.CloudflareChallengeError: Detected a Cloudflare version 2 Captcha challenge, This feature is not available in the opensource (free) version.

我正在嘗試訪問該站點以從中刮取資料,但它使用了 cloudfare 保護,因此我找到了此解決方案但不斷收到此錯誤,還有其他方法可以訪問此站點嗎?

uj5u.com熱心網友回復:

您可以使用ScrapingAnt代替 cloudcraper - 它非常有用,除非您需要抓取大量頁面(免費層每月僅允許 10k 請求)。如果您注冊,他們會給您一個令牌,您可以將其粘貼到下面的代碼中:

import requests
import urllib.parse
from bs4 import BeautifulSoup

sa_key = 'YOUR_API_TOKEN' # paste here
sa_api = 'https://api.scrapingant.com/v2/general'
qParams = {'url': 'https://coinsniper.net/new', 'x-api-key': sa_key}
reqUrl = f'{sa_api}?{urllib.parse.urlencode(qParams)}'  

r = requests.get(reqUrl)
# print(r.text) # --> html
soup = BeautifulSoup(r.content, 'html.parser')

我用自己的函式列印(有時我發現它比 just 更具可讀性)以獲取輸出print(prettify_htmlText(soup))print(soup.text)
