巧了！昨天分析了 “好看视频” 的视频下载链接，想着楼主提到的 “视频链接” 应该就在那里，一测试果然如此！
先附上对上述链接 https://haokan.baidu.com/v?vid=15131088464706533363 的下载信息提取结果：

下面是 Python 代码可以根据 “好看视频” 的播放页链接快速提取视频的下载链接，也可以按照这个逻辑改为油猴脚本，主要过程是：
- 提取出 HTML 中的
encrptedVideoMeta 值
- 对该值进行解密即可，解密算法的分析涉及到
js，由于悬赏区不能上传附件（图片），所以省略了。
import httpx
import re
import json
import base64
from io import BytesIO
from pprint import pprint
def get_video_info(html: str):
# 用正则表达式取出 encrptedVideoMeta
meta = re.search(r'"encrptedVideoMeta":\s*"(.*?)"', html).group(1)
# 以下进行解密
a = b"guanghui456"
b = base64.b64decode(meta)
c = BytesIO()
for i in range(len(b)):
c.write(bytes([b[i] ^ a[i % len(a)]]))
pprint(json.loads(c.getvalue()))
if __name__ == "__main__":
url = input("URL: ")
headers = {"User-Agent": "Mozilla/5.0"}
html = httpx.get(url, headers=headers).text
get_video_info(html)
