channelId=UCxA5VFvNdlGUTingA9jMu3A

最大结果=50

pageToken=CIkCEAE

pageToken=CIkCEAE

 "etag": "\"Bdx4f4ps3xCOOo1WZ91nTLkRZ_c/fRLRzDJR1r68v6VuXm7NWw28YHw\"",
 "nextPageToken": "CIkCEAA",
 "prevPageToken": "CNcBEAE",

推荐答案

YouTube 官方文档在其页面中的演示功能可能会出错.

It might happen something wrong with YouTube official documentation's demo feature in their page.

如果您在 Google API 资源管理器中尝试相同的请求，您将获得下一页/上一页中的项目.

If you try the same request in Google API explorer, you'll get the items in the next/previous pages.

N.B 我遇到过类似的情况，在 YouTube 的官方文档页面不起作用，但是，通过在Google 数据 API，它按预期工作.

N.B I have face similar situations where in the YouTube's official documentation page does not work, but, by testing the same request in Google Data API, it works as expected.

我的建议是，下次遇到类似情况时，请尝试以下这些地方:

My advice is, next time you face a similar situation, try in these places:

  • 在 YouTube 官方 deocumentation 页面中测试您的请求.
  • 在 Google API Explorer 中测试您的请求.
  • 在您的网站、API、页面等中测试您的请求.

示例 - 您请求的第 1 页使用给定的 channel_id UCxA5VFvNdlGUTingA9jMu3A.

Example - page 1 of you request using the given channel_id UCxA5VFvNdlGUTingA9jMu3A.
