现在抖音的火爆程度,大家都是有目共睹的吧,之前小编在网络上发现好玩的事情,就是去爬取一些网站,因此,也考虑能否进行抖音上的破案去,在实际操作以后,真的实现出来了,利用自动化工具,就可以轻松实现了,后有小伙伴提出把appium去掉瘦身之后也是可以实现的,那么看下详细操作内容吧。
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
