爬取会员视频通常涉及绕过付费限制或登录验证，这可能违反网站的服务条款或相关法律（如《数字千年版权法》）。以下提供两种合法合规的技术实现思路，供学习参考：
方法一：模拟登录后访问公开内容（需合法授权）
假设目标网站提供公开的API或允许合法爬取非会员视频，可通过模拟登录获取基础数据。
import requests
from bs4 import BeautifulSoup
# 配置登录信息（需用户授权）
login_url = "https://example.com/login"
video_url = "https://example.com/video/123"
credentials = {"username": "your_username", "password": "your_password"}
# 创建会话并登录
session = requests.Session()
login_response = session.post(login_url, data=credentials, timeout=5)
if login_response.status_code == 200:
# 获取视频页面（假设有权限访问）
video_response = session.get(video_url)
soup = BeautifulSoup(video_response.text, 'html.parser')
# 解析公开视频链接（示例：假设视频在
video_tag = soup.find("video")
if video_tag:
video_src = video_tag.get("src")
print(f"Found video source: {video_src}")
else:
print("No accessible video found.")
else:
print("Login failed.")
方法二：调用合法API接口（需平台许可）
若平台提供开放API，可通过官方接口获取数据：
import requests
api_url = "https://api.example.com/videos"
api_key = "your_legitimate_api_key" # 需申请合法密钥
headers = {"Authorization": f"Bearer {api_key}"}
params = {"video_id": "123", "quality": "720p"}
response = requests.get(api_url, headers=headers, params=params)
if response.status_code == 200:
video_data = response.json()
print(f"Video title: {video_data['title']}")
print(f"Stream URL: {video_data['stream_url']}")
else:
print(f"API request failed: {response.text}")
注意事项
法律风险：未经许可爬取付费内容可能涉及侵权，务必遵守目标网站的robots.txt和服务条款。反爬机制：多数平台会对频繁请求或异常登录进行封禁，需添加time.sleep()等延迟策略。替代方案：考虑使用平台提供的官方下载工具或合作API。
