使用说明

环境准备：

bash 复制代码

# 安装依赖库
pip install requests beautifulsoup4 selenium webdriver-manager

浏览器驱动配置：
- 安装Chrome浏览器
- 根据Chrome版本下载对应chromedriver
- 将驱动文件放在系统PATH路径或代码同级目录
运行程序：
bash 复制代码
```
python hotlist_crawler.py
```

功能扩展

添加新平台：

python 复制代码

def fetch_新平台_hot():
    # 实现抓取逻辑
    return [{'title':..., 'url':...}]

# 更新platforms字典
platforms = {
    ...
    '新平台名称': fetch_新平台_hot
}

输出示例

控制台输出：

perl 复制代码

====== 正在抓取 微博热搜 ======
完成！耗时1.23秒，获取到50条数据

====== 正在抓取 知乎热榜 ======
完成！耗时2.15秒，获取到50条数据

...

===== 数据已保存到 hot_data.json =====

===== 最新热榜摘要 =====

▶ 微博热搜（共50条）:
  1. #神舟十八号发射成功#...
     链接：https://s.weibo.com/weibo?q=%23%E7%A5%9E%E...
  2. #五一假期出行预测#...
     链接：https://s.weibo.com/weibo?q=%23%E4%BA%94%...

▶ 今日头条（共20条）:
  1. 国际油价创年内新高...

注意事项

反爬策略：
- 在HEADERS中添加有效的Cookie
- 使用代理IP池（推荐使用付费代理服务）
python 复制代码
```
# 在请求时添加代理
response = requests.get(url, proxies={'http': 'http://ip:port'})
```

性能优化：

python 复制代码

# 启用多线程（示例）
from concurrent.futures import ThreadPoolExecutor

with ThreadPoolExecutor(max_workers=3) as executor:
    futures = {executor.submit(func): name for name, func in platforms.items()}
    for future in as_completed(futures):
        name = futures[future]
        all_data[name] = future.result()

定时任务：

python 复制代码

# 使用APScheduler定时执行
from apscheduler.schedulers.blocking import BlockingScheduler

scheduler = BlockingScheduler()
@scheduler.scheduled_job('interval', hours=1)
def scheduled_job():
    main()
scheduler.start()

建议根据实际需求调整请求频率和反爬策略，完整代码已包含主流平台的热榜抓取功能，可直接运行或二次开发。
