要使用Python编写一个代理IP爬虫,你需要遵循以下步骤:
requests和fake_useragent库。如果没有,请使用以下命令安装:pip install requests pip install fake_useragent import requests from fake_useragent import UserAgent proxies = [ {'http': 'http://proxy1:port'}, {'http': 'http://proxy2:port'}, {'http': 'http://proxy3:port'}, # 更多代理IP... ] fake_useragent库生成随机的User-Agent,以避免被目标网站屏蔽:ua = UserAgent() def fetch(url): proxy = random.choice(proxies) headers = {'User-Agent': ua.random} try: response = requests.get(url, headers=headers, proxies=proxy, timeout=5) response.raise_for_status() return response.text except requests.exceptions.RequestException as e: print(f"Error fetching {url}: {e}") return None fetch函数获取页面内容:url_list = [ 'https://example.com/page1', 'https://example.com/page2', # 更多URL... ] for url in url_list: content = fetch(url) if content: # 处理页面内容,例如保存到文件或解析HTML with open(f"{url}.html", "w", encoding="utf-8") as f: f.write(content) 这样,你的代理IP爬虫就可以运行了。请注意,根据目标网站的限制,你可能需要定期更新代理IP池和User-Agent。此外,确保遵循目标网站的robots.txt规则,并遵守相关法律法规。
