python requests下载油管

Python中的requests库可以用于发送HTTP请求，因此可以使用requests库下载＊＊＊3. 使用requests库下载视频。

具体实现可以参考以下代码：

import requests

# 从YouTube获取视频ID
url = "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
video_id = url.split("=")[1]

# 构造视频下载链接
download_url = f"https://www.youtube.com/get_video_info?video_id={video_id}"
response = requests.get(download_url)

# 解析视频下载链接
data = response.text
url_encoded_fmt_stream_map = data.split("&url_encoded_fmt_stream_map=")[1]
url_encoded_fmt_stream_map = url_encoded_fmt_stream_map.split("&")[0]
url_encoded_fmt_stream_map = url_encoded_fmt_stream_map.replace("%2F", "/").replace("%3A", ":").replace("%3F", "?").replace("%3D", "=").replace("%26", "&")
url_encoded_fmt_stream_map = url_encoded_fmt_stream_map.split(",")
url_encoded_fmt_stream_map = [x for x in url_encoded_fmt_stream_map if "itag=22" in x][0]
url_encoded_fmt_stream_map = url_encoded_fmt_stream_map.split("&")
url_encoded_fmt_stream_map = [x for x in url_encoded_fmt_stream_map if "url=" in x][0]
download_link = url_encoded_fmt_stream_map.split("url=")[1]

# 使用requests库下载视频
response = requests.get(download_link)
with open("video.mp4", "wb") as f:
    f.write(response.content)
