# 怎么利用Python网络爬虫获取电影天堂视频下载链接
## 前言
在互联网时代，获取影视资源的方式多种多样。电影天堂（www.dytt8.net）作为国内知名的影视资源站点，提供了大量高清电影、电视剧的下载链接。本文将详细介绍如何利用Python网络爬虫技术，自动化获取电影天堂的视频下载链接。
---
## 一、准备工作
### 1.1 技术栈选择
- **Python 3.x**：基础编程语言
- **Requests库**：发送HTTP请求
- **BeautifulSoup4**：HTML解析
- **正则表达式**：数据清洗
- **Fake-Useragent**：伪装浏览器头
### 1.2 安装依赖库
```bash
pip install requests beautifulsoup4 fake-useragent
电影天堂的典型页面结构： - 首页：分类导航（最新电影、国内电影等） - 详情页：包含磁力链接/迅雷下载地址 - 反爬机制：简单IP限制、无验证码

url = f"https://www.dytt8.net/html/gndy/dyzz/list_23_{page}.html"
headers = {"User-Agent": UserAgent().random}
try:
response = requests.get(url, headers=headers, timeout=10)
response.encoding = 'gb2312' # 注意编码问题
soup = BeautifulSoup(response.text, 'html.parser')
movie_links = []
for a in soup.select('.co_content8 ul a'):
if 'href' in a.attrs:
movie_links.append({
'title': a.text,
'url': 'https://www.dytt8.net' + a['href']
})
