Python爬蟲下載視頻文件部分源碼

分享一下我自己整理的代碼，改兩個參數就可使用（掃描下方二維碼獲取python學習資料）

import requests
import time        
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36'
}
movie_url = '在這裡輸入視頻地址，例如：http://www.***********.mp4'
movie_name = '視頻標題'
downsize = 0
print('開始下載')
startTime = time.time()
req = requests.get(movie_url, headers=headers, stream=True, verify=False)  
      with(open(movie_name+'.mp4', 'wb')) as f:
          for chunk in req.iter_content(chunk_size=10000):  
              if chunk:
                  f.write(chunk)
                  downsize += len(chunk)
                  line = 'downloading %d KB/s - %.2f MB， 共 %.2f MB'
                  line = line % (
                    downsize / 1024 / (time.time() - startTime), downsize / 1024 / 1024, downsize / 1024 / 1024)
                  print(line)
