1. 发送请求 (访问网站)

response = requests.get(url, headers=headers)
# 乱码
response.encoding = \'utf-8\'
# <Response [200]>: 访问成功

2. 获取数据

html_data = response.text

3. 解析数据 (base64解码)

# _SSR_HYDRATED_DATA=(.*?)</script>
# (.*?): 匹配任何字符 换行符除外
json_str = re.findall(\'_SSR_HYDRATED_DATA=(.*?)</script>\', html_data)[0]
# undefined 替换为 null
json_str = json_str.replace(\'undefined\', \'null\')
json_dict = json.loads(json_str)
title = json_dict[\'anyVideo\'][\'gidInformation\'][\'packerData\'][\'video\'][\'title\']
title = title.replace(\' \', \'\')
video_url = json_dict[\'anyVideo\'][\'gidInformation\'][\'packerData\'][\'video\'][\'videoResource\'][\'dash\'][\'dynamic_video\'][\'dynamic_video_list\'][-1][\'main_url\']
audio_url = json_dict[\'anyVideo\'][\'gidInformation\'][\'packerData\'][\'video\'][\'videoResource\'][\'dash\'][\'dynamic_video\'][\'dynamic_audio_list\'][-1][\'main_url\']
video_url = base64.b64decode(video_url)
audio_url = base64.b64decode(audio_url)
video_url = video_url.decode()
audio_url = audio_url.decode()

4. 保存数据 (视频 音频)

源码、解答、资料加Q群：832157862免费领取哦~
video_data = requests.get(video_url).content
with open(f\'{title}.mp4\', mode=\'wb\') as f:
    f.write(video_data)
audio_data = requests.get(audio_url).content
with open(f\'{title}.mp3\', mode=\'wb\') as f:
    f.write(audio_data)
ffmpeg = r\'ffmpeg -i \' + title + \'.mp4 -i \' + title + \'.mp3 -acodec copy -vcodec copy \' + title + \'-out.mp4\'
subprocess.run(ffmpeg)
os.remove(f\'{title}.mp3\')
os.remove(f\'{title}.mp4\')
