使用 youtube API V3 [Google APIs Client Library for Python] 分页时的意外行为 [英] Unexpected behaviour while paging with youtube API V3 [Google APIs Client Library for Python]

问题描述

使用适用于 Python 的 Google API 客户端库和搜索端点 API V3 执行以下查询:

Using the Google APIs Client Library for Python and the search endpoint API V3 did the follwing query:

search_response = youtube.search().list(
                        q="Mallorca",
                        part="id,snippet",
                        maxResults=50,
                        order="date",
                        publishedBefore="2014-1-1T2:00:00Z",
                        publishedAfter="2014-1-1T1:00:00Z",
                    ).execute() 

响应显示 search_response.pageInfo.totalResults 为 186.这意味着需要分页来检索所有结果.然而，在这个回复中，我在 search_response.items 下只得到一个结果(一个视频)，而不是第一页的预期 50.

The response shows a search_response.pageInfo.totalResults of 186. That means that paging is needed to retrieve all results. However in this response I get only one result (one video) under search_response.items instead of the expected 50 of the first page.

如果我使用 nextPageToken (=CDIQAA) 查询下一个结果页面:

If I use the nextPageToken (=CDIQAA) to query for the next results page:

search_response = youtube.search().list(
                        q="Mallorca",
                        part="id,snippet",
                        maxResults=50,
                        order="date",
                        publishedBefore="2014-1-1T2:00:00Z",
                        publishedAfter="2014-1-1T1:00:00Z",
                        pageToken= "CDIQAA"
                    ).execute() 

我再次仅获得一个结果，即在第一次查询时检索到的相同视频(相同的 videoId).当我浏览 search_response 的下一页直到没有更多页面可用(nextPageToken 未包含在响应中)时，也会发生同样的事情.

I obtain again only one result, the same video (same videoId) retrieved at the first query. Same thing happens when I navigate through the next pages of the search_response until no more pages are available (nextPageTokennot included in the response).

已阅读上一个问题:

页面令牌使用 youtube api v3

还有这个:

是youtube数据吗如果您使用页面令牌，api 分页是否一致?(v3 数据 API)

但他们没有解释为什么我只得到一个结果，即响应提供的所有页面都使用相同的视频.

but they don't explain why I get only one result, the same video for all pages delivered by the response.

这是 youtube API 的问题还是我做错了什么?感谢您的帮助.

Is this an issue of the youtube API or I am doing something wrong? Thanks for your help.

推荐答案

这是 youtube API 的未解决问题:

This is an open issue for the youtube API:

预计很快会修复...

如果不应用排序，可以获得正确的结果.

The right results can be obtained if ordering is not applied.
