1.获取yt的cookie

1）google浏览器下载Get cookies.txt LOCALLY插件

https://chromewebstore.google.com/detail/get-cookiestxt-locally/cclelndahbckbenkjhflpdbgdldlbecc

2）导出cookie

推荐使用cookies方式，因为：
更安全，不需要存储密码
避免频繁登录导致的验证码问题
可以访问账号订阅的内容
支持年龄限制视频的下载
记住要定期更新cookies以确保其有效性。

2.yt-dlp下载yt-dlp的GitHub地址

1）使用Pycharm(2024.3)进行代码demo编写

2）使用的python版本3.9.13

3）Pycharm下载对应的第三方库yt-dlp

4）使用命令进行下载

pip install yt-dlp

提示pip警告
[notice] A new release of pip is available: 23.2.1 -> 24.3.1
[notice] To update, run: python.exe -m pip install --upgrade pip

更新就行了
python.exe -m pip install --upgrade pip

5）复制cookie到根目录

5）python代码

import yt_dlp
from pathlib import Path
import osdef yt_test(url):try:# 创建下载目录video_path = Path("downloads/video")audio_path = Path("downloads/audio")video_path.mkdir(parents=True, exist_ok=True)audio_path.mkdir(parents=True, exist_ok=True)# yt-dlp 基础配置common_opts = {'cookiefile': r'www.youtube.com_cookies.txt','quiet': False,'no_warnings': False,'verbose': True,'proxy': 'http://127.0.0.1:10809','socket_timeout': 30,'retries': 3,'nocheckcertificate': True,'prefer_insecure': True}print("开始下载视频...")print(f"使用cookies文件: {common_opts['cookiefile']}")# 视频下载选项video_opts = {**common_opts,'format': 'best[ext=mp4][height<=720]/best[height<=720]/best','outtmpl': str(video_path / '%(title)s.%(ext)s'),}# 音频下载选项audio_opts = {**common_opts,'format': 'bestaudio[ext=m4a]/bestaudio','outtmpl': str(audio_path / '%(title)s.%(ext)s'),}# 获取视频信息print("正在获取视频信息...")with yt_dlp.YoutubeDL(common_opts) as ydl:info = ydl.extract_info(url, download=False)title = info['title']duration = info['duration']thumbnail = info['thumbnail']print(f"视频标题: {title}")print(f"视频时长: {duration // 60}:{duration % 60:02d}")print(f"缩略图URL: {thumbnail}")# 下载视频print("\n开始下载视频文件...")with yt_dlp.YoutubeDL(video_opts) as ydl:ydl.download([url])# 下载音频print("\n开始下载音频文件...")with yt_dlp.YoutubeDL(audio_opts) as ydl:ydl.download([url])# 获取下载后的文件路径video_file = next(video_path.glob(f"{title}.*"))audio_file = next(audio_path.glob(f"{title}.*"))print("\n下载完成!")print(f"视频文件: {video_file}")print(f"音频文件: {audio_file}")return {"status": "success","title": title,"duration": f"{duration // 60}:{duration % 60:02d}","thumbnail": thumbnail,"video_path": str(video_file),"audio_path": str(audio_file)}except Exception as e:print(f"\n下载过程中出错: {str(e)}")return {"status": "error", "message": str(e)}if __name__ == "__main__":# 测试URLtest_url = "******.com/watch?v=_KFzaJSxBcY"print("测试")print("-" * 50)print(f"测试URL: {test_url}")print("-" * 50)result = yt_test(test_url)if result["status"] == "success":print("\n测试成功!")print("-" * 50)print(f"标题: {result['title']}")print(f"时长: {result['duration']}")print(f"视频文件: {result['video_path']}")print(f"音频文件: {result['audio_path']}")else:print("\n测试失败!")print("-" * 50)print(f"错误信息: {result['message']}")

6）运行测试

3.注意事项

1）配置

猫: 常用7890
V2: 常用 10808/10809
S: 常用1080

2）yt-dlp配置

common_opts = {
‘cookiefile’: r’cookies.txt’,
‘quiet’: False,
‘no_warnings’: False,
‘verbose’: True,
#和上方的端口进行对应
‘proxy’: ‘http://127.0.0.1:10809’,
‘socket_timeout’: 30,
‘retries’: 3,
‘nocheckcertificate’: True,
‘prefer_insecure’: True
}
