利用python怎么爬取抖音视频-创新互联
利用python怎么爬取抖音视频？针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
1、mitmproxy/mitmdump抓包
import requests path = 'D:/video/' num = 1788 def response(flow): global num target_urls = ['url'] for url in target_urls: if flow.request.url.startswith(url): filename = path + str(num) + '.mp4 res = requests.get(flow.request.url, stream=True) with open(filename, 'ab') as f: f.write(res.content) f.flush() print(filename + '下载完成') num += 1
2、Appium对手机进行模拟操作
利用Start Server按钮即可启动appium服务
再点击Start Session即可启动Android手机上的抖音app并进入到启动页面
3、python脚本来驱动app，直接在pycharm运行即可
实例扩展：
