YouTube数据API版本3分页 [英] Youtube data API version 3 pagination

问题描述

我了解youtube响应中包含下一页和上一页标记，我们可以使用这些标记转到上一页和下一页.

I understand that youtube response contains the next and previous page tokens and we can use those to go to previous and next pages.

例如:

https://www.googleapis.com/youtube/v3/search?&key={key}&part=snippet&maxResults=20&order=viewCount&q=abc&type=video&videoDuration=long&videoType=movie&pageToken=Cd323A

我的问题是如何导航到特定搜索的 n 页?

My question is how can I navigate to nth page of particular search?

请注意，有些人可能认为这是不可能的.但是我看到一些站点实现了这一点.

Please note that some people may see this is impossible. But I have seen some site implemented this.

推荐答案

Youtube API仅提供NextPageToken和PreviousPageToken，就是这样，很抱歉:请参见此处的文档:

Youtube API only provides NextPageToken and PreviousPageToken, that's it, sorry: see documentation here: https://developers.google.com/youtube/v3/docs/videos/list

您仍然可以创建一个分页项目，但是您必须通过多次调用URL，每次在请求中将NextPageToken作为pageToken传递并缓存结果来实现它.

You can still make a pagination item but you will have to implement it by calling multiple times the URL, passing the NextPageToken as pageToken in your requestion every time, and caching results.

顺便说一下，这里已经回答了这个问题(请参见答案的第一点):

By the way, this question is already answered here (see the 1st point of the answer): youtube data api v3 php search pagination?

报价:

在特定情况下，您每页需要50页，而您 显示3分页，如(1,2，NEXT)，则需要获取结果 两次.两种结果都将保留在缓存中，因此对于第1页和第2页 结果将从缓存中检索.接下来，请确保 您正在通过发送nextPageToken再次使Google查询.

In particular your case where you need 50 pages per page and you are showing 3 pagination like (1,2,NEXT) then you need to fetch results two times. Both the results you will keep in cache so for page 1 and 2 results will be retrieved from cache. For next you make it sure that you are making query google again by sending nextPageToken.

因此要显示分页1-n，每页显示50个结果，则需要 向Google api进行n-1个查询.但是，如果您显示的是每条10条结果 页面，然后您可以对50个结果进行单个查询，就可以使用该查询 在检索到的结果的帮助下显示前5页(1-5)，并在 接下来，您应该再次发送上述的下一页令牌.

Thus to show pagination 1-n and every page 50 results then you need to make n-1 queries to google api. But if you are showing 10 results per page then you cane make single query of 50 results using which you can show first 5 pages (1-5) with the help of retrieved results and at next you should again send next page token like above.

注意-Google youtube api最多可提供50个结果.

NOTE- Google youtube api provide 50 results max.
