How to get a user's entire YouTube watch history?
提问by Fsmv
I'm trying to get a full list of watched videos for a given user in my YouTube API application. I want to add up total duration of all videos.
我正在尝试为我的 YouTube API 应用程序中的给定用户获取已观看视频的完整列表。我想把所有视频的总时长加起来。
When I get the list of videos from history playlist, the API caps it at 50 items. There's pagination but total amount of items is 50 (not just per page); I can't access more data with the API it appears.
当我从历史播放列表中获取视频列表时，API 将其限制为 50 个项目。有分页，但项目总数为 50（不仅仅是每页）；我无法使用它出现的 API 访问更多数据。
Is there any way I can get this playlist without the data cap? I'm hoping for another method (of using the API) or a way to do it without the API. I know YouTube stores this data because I can view my entire history (far more that 50 videos).
有什么办法可以在没有数据上限的情况下获得此播放列表？我希望有另一种方法（使用 API）或一种无需 API 的方法。我知道 YouTube 会存储这些数据，因为我可以查看我的整个历史记录（远远超过 50 个视频）。
I'm using this code:
我正在使用此代码：
var requestOptions = {
playlistId: playlistId,
part: 'snippet',
maxResults: 50
};
gapi.client.youtube.playlistItems.list(requestOptions);
where playlistIdis the id of the history playlist I got from a gapi.client.youtube.channels.listrequest.
playlistId我从gapi.client.youtube.channels.list请求中获得的历史播放列表的 ID在哪里。
Edit (2017):I want to clarify that it was always my intention to download my own history, just out of interest to see how much time I have spent watching videos. I still have not been able to do this.
编辑（2017 年）：我想澄清一下，我一直打算下载自己的历史记录，只是为了看看我花了多少时间观看视频。我仍然无法做到这一点。

I wrote a scraper(in Python 2.7(updated for 3.5) and Scrapy) for this task a while ago. Sans official API, it uses a logged in session cookie and html parsing. Dumps to SQLite by default. https://github.com/zvodd/Youtube-Watch-History-Scraper
不久前，我为此任务编写了一个刮刀（在 Python 2.7（更新为 3.5）和 Scrapy 中）。Sans 官方 API，它使用登录的会话 cookie 和 html 解析。默认转储到 SQLite。 https://github.com/zvodd/Youtube-Watch-History-Scraper
How it's done: essentially it opens the url
它是如何完成的：本质上它打开了 url
https://www.youtube.com/feed/history'
with a valid(logged in) session cookie taken from Chrome. Scrapes all video entries for name, vid(url), channel/user, description, length. Then it finds the button at the bottom of the page with the attribute data-uix-load-more-hrefwhich contains the link to the next page, something like:
使用从 Chrome 获取的有效（登录）会话 cookie。抓取所有视频条目的名称、vid(url)、频道/用户、描述、长度。然后它会在页面底部找到带有属性data-uix-load-more-href的按钮，其中包含指向下一页的链接，例如：
"/browse_ajax?action_continuation=1&continuation=98h32hfoasau0fu928hf2hf908h98hr%253D%253D&target_id=item-section-552363&direct_render=1"
... re-scrapes the video entries from there and dumps them all into an sqlite database; which you can search entries by any of the fields (name, length, user, description, etc).
...从那里重新抓取视频条目并将它们全部转储到 sqlite 数据库中；您可以按任何字段（名称、长度、用户、描述等）搜索条目。
So until they change their feed/history page, it's doable and done. I might even update it.
所以在他们改变他们的提要/历史页面之前，这是可行的。我什至可能会更新它。

The API currently only retrieves the last two weeks of Watch History. For more information refer to the Bug Issue reported: https://code.google.com/p/gdata-issues/issues/detail?id=4642
API 当前仅检索最近两周的观看历史记录。有关更多信息，请参阅报告的错误问题：https: //code.google.com/p/gdata-issues/issues/detail?id=4642
Note:There is a similar question on SO asked here: YouTube API v3 returns truncated watch history
注意：这里有一个关于 SO 的类似问题：YouTube API v3 返回截断的观看历史记录

It seems like this is a known bug originally reported in 2013. The exact same behavior is explained on a Google Code thread: https://code.google.com/p/gdata-issues/issues/detail?id=4642
这似乎是 2013 年最初报告的已知错误。在 Google 代码线程中解释了完全相同的行为：https: //code.google.com/p/gdata-issues/issues/detail?id=4642

Brainstorming, never tried: Have you tried notusing the API and instead parsing the https://www.youtube.com/feed/historyURL?
头脑风暴，从未尝试过：您是否尝试过不使用 API 而是解析https://www.youtube.com/feed/historyURL？
Theoretically, the user browsing could be emulated, including the pagination. I am not aware of how hard though (probably very), since you need to deal with authentication and YouTube probably tries to verify that a human is browsing.
理论上，可以模拟用户浏览，包括分页。我不知道有多难（可能非常困难），因为您需要处理身份验证，而 YouTube 可能会尝试验证是否有人在浏览。
