我正在尝试提取 Upload Dates , Titles , URLsDurations来自特定播放列表的所有 Youtube 视频 youtube-dl ,我不需要视频——只需要上面的数据。
到目前为止,我已经测试了 Alen Paul Varghese 在此处建议的以下两种方法:
Youtube-dl's GitHub Doc Used as reference
The Playlist URL used for testing
方法#1

youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD > example.json

方法#2
youtube-dl --get-upload_date https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD > example.txt
方法#1 输出一个完整的 json 转储——每个视频大约 3000 行——处理大量 Youtube 视频播放列表非常不方便——但它包含 4 个所需的数据。
方法#2 返回以下错误:
youtube-dl: error: no such option: --get-upload_date
我要宠 方法#2 将输出数据限制为仅需要的数据( upload datesTitlesURLsDurations ),遵循 Alen Paul Varghese's 2nd suggestion并在检查 upload_date 后是有效的 youtube-dl选项在这里 Youtube-dl's GitHub Doc Used as reference .
为什么不 upload_data选项得到验证?
有什么替代方案可以限制数据?
我非常感谢您提供的有用建议。
这是 json 转储文件:
example.json

我已经成功安装 Chocolatey NuGetAdmin CMD使用 chocolatey install jq 安装 jq 1.5按照 Download jq - Windows 的要求

然后我跑了你的@pierpy youtube-dl 命令:
youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq '{"date": .upload_date,"title": .title,"URL": .url,"duration": .duration}'
并得到一个语法错误,输出如下:

C:\Users\###\Documents\youtube-dl>
然后我用谷歌搜索了错误 jq: error: syntax error, unexpected INVALID_CHARACTER, expecting $end (Windows cmd shell quoting issues?) 并从这个建议中找到了见解:
It's all about the quoting
然后我相应地调整了您的 @pierpy youtube-dl 命令单引号到双引号:
youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq "{"date": .upload_date,"title": .title,"URL": .url,"duration": .duration}"
现在它输出数据 Upload Dates , Titles , URLsDurations刚好需要。
最终输出:
C:\Users\###\Documents\youtube-dl>youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq "{"date": .upload_date,"title": .title,"URL": .url,"duration": .duration}"

最后一期:

得到的 URLs不要显示标准视频。
为什么不?

Youtube-dl's GitHub Doc Used as reference它指出:
url (string): Video URL
如何检索标准的 Youtube 视频 URL?
上一期答案:
我刚刚查看了我的 example.json昨天生成的文件,发现标准的 Youtube 视频 URL 接受 webpage_url代替 url .

最佳答案

您需要使用方便的工具过滤输出,例如 jq :
粘贴此命令行:youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq '{"date": .upload_date,"title": .title,"URL": .url,"duration": .duration}'您可以获得jq来自 https://stedolan.github.io/jq/download/
更新 :
key "webpage_url"保存标准 YouTube 网址(如果需要)。
有关各种可能键的完整列表,请运行:youtube-dl --skip-download --print-json https://www.youtube.com/playlist?list=PLRqwX-V7Uu6by61pbhdvyEpIeymlmnXzD | jq keys这给出了原始 JSON 中的完整键名。
