概述

最近看到这个视频课程: 【吴恩达团队Tensorflow2.0实践系列课程第一课】TensorFlow2.0中基于TensorFlow2.0的人工智能、机器学习和深度学习简就想下载到本地防止被和谐… 所以就使用you-get 下载. you-get 这个 repo clone下来就可以了: 官方repo. 想着以前也提交过代码再看看也没啥大问题.

使用下载

使用如下命令:

you-get --debug --playlist https://www.bilibili.com/video/BV1zE411T7nb

这个下载没有问题, 但是我发现中文字幕没有了.

所以继续研究了下如何下载

观察视频, 发现字幕是可以拖动的, 于是加上firefox 断点
加上断点后拦截请求, 发现有一个请求会初始化对应的subtitles

在这里插入图片描述像上面这个复制为curl 就可以测试:

curl 'https://api.bilibili.com/x/player.so?id=cid%3A162260003&aid=95051759&bvid=BV1zE411T7nb&buvid=FB2BB46F-B1F3-4BDA-A589-333489Q4e0411A155830infoc' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:78.0) Gecko/20100101 Firefox/78.0' -H 'Accept: */*' -H 'Accept-Language: zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2' --compressed -H 'Origin: https://www.bilibili.com' -H 'Referer: https://www.bilibili.com/video/BV1zE411T7nb' -H 'Connection: keep-alive' -H $'Cookie: _uuid=3FFA2652-F830-7C37-F9A4-333489Q4e0411A155830infoc; buvid3=FB2BB46F-B1F3-4BDA-A589-33348940411A155830infoc; sid=cejpsw6m; CURRENT_FNVAL=16; LIVE_BUVID=AUTO9515820831073003; rpdid=|(k)~RY~mkk|0J\'ul)k|)Juuk; im_notify_type_11615329=0; DedeUserID=11615329; DedeUserID__ckMd5=7c197013cd07c4b6; SESSDATA=b2ce8c5b%2C1600861501%2Ca9549*31; bili_jct=b7000d5d160ed086c798d55808a55f75; PVID=2; CURRENT_QUALITY=80; bsource=search_google; flash_player_gray=false; html5_player_gray=false; bfe_id=6f285c892d9d3c1f8f020adad8bed553' -H 'Pragma: no-cache' -H 'Cache-Control: no-cache' -H 'TE: Trailers'

这里面需要cid, aid, bvid和 buvid. 只有最后这个buvid不知道是干啥的, 折腾了很久发现这个是cookie 中的uuid. 然后经过一些测试后发现该请求还需要一个Reffer 不然会报错-412 (应该就是412 估计是b站自己定义的错误码, 412 意味着前置条件未满足):
在这里插入图片描述所以获取该url的最简单地请求是:

https://api.bilibili.com/x/player.so?id=cid%3A162260003&aid=95051759&bvid=BV1zE411T7nb&buvid=FB2BB46F-B1F3-4BDA-A589-333489Q4e0411A155830infoc

with header -H 'Referer: https://www.bilibili.com/video/BV1zE411T7nb'  后面这个是bv号

解析上面的xml输出

上面的输出有个很重要的url就是 subtitles中的json url:

{"allow_submit":false,"lan":"","lan_doc":"","subtitles":[{"id":23916631605379079,"lan":"zh-CN","lan_doc":"中文（中国）","is_lock":false,"subtitle_url":"//i0.hdslb.com/bfs/subtitle/dfb81041cf92b5c2ebce2540cd14c9e49674f460.json"}]}

下载这个json后我找到了最终的中文字幕:
格式如下:
在这里插入图片描述
4. 将json转为srt字幕
参考的: 这里

修改you-get 代码
修改之后的commit在这里可以直接用我的repo. (可能需要修改下buvid的值每个人应该不一样或者用 you-get的cookie file 应该也可以我没去测试).

结论

下载了所有课程并共享到百度云了百度云链接: https://pan.baidu.com/s/1S93he0skiUwAihUH309-2Q 密码: sn5a
以后有时间了把代码merge到 you-get 中现在懒得提PR了.
有个小疑问, 有没有什么快速的办法在FIREFOX中搜索某个字符串是哪个url返回的呢? 可能前端的同学更加清楚
