python爬取抖音视频的实例分析

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

实例扩展：

import requests
import json
import re
import os
from pprint import pprint as pp
import queue

    return get_aweme_list(contentJson.get('max_cursor')) # 有的话获取参数max_cursor
  get_aweme_list()

 # 下载视频
 def get_download(self):
  while True:
   video_name, video_url = self.queue.get()
   file_name = video_name + '.mp4'
   file_path = os.path.join(self.target_folder, file_name)
   if not os.path.isfile(file_path):
    print('download %s form %s.\n' % (file_name, video_url))
    times = 0
    while times < 10:
     try:

      with open(file_path, 'wb') as f:

        f.write(chunk)
       print('下载成功')
      break
     except:
      print('下载失败')
     times += 1

 # 创建对应的文件夹

 def mkdir_dir(self):
  current_folder = os.getcwd()
  self.target_folder = os.path.join(
   current_folder, 'download/%s' % self.user_id)
  if not os.path.isdir(self.target_folder):
   os.mkdir(self.target_folder)

 # 短链接转长地址
 def get_RealAddress(self, url):
  if url.find('v.douyin.com') < 0:
   return url
  response = requests.get(
