用python制作個視頻下載器

import requests
page = 1
keyword = 'xxxxx' # xxxxx為搜索的關(guān)鍵字
url = 'https://haokan.baidu.com/videoui/page/search?pn=%drn=10_format=jsontab=videoquery=%s'%(page,keyword)
res = requests.get(url)
data = res.json()

p = 'video class="video" src=(.*?)>'

def get_videoUrl(vid):
 '''
 提取視頻信息中的視頻源地址
 '''
 res = requests.get('https://haokan.baidu.com/v?vid=%s'%vid)
 html = res.text
 videoUrl = re.findall('video class="video" src=(.*?)>',html)[0]
 return videoUrl

def download_video(vid):
 '''
 下載視頻文件
 '''
 savePath = 'xxxxx.mp4' # 定義存儲的文件名
 videoUrl = get_videoUrl(vid) # 獲取視頻下載地址 
 res = requests.get(videoUrl)
 with open(savePath,'wb') as f:
 f.write(res.content)
