【中文标题】YouTube API v3 未检索频道的视频【英文标题】：YouTube API v3 not retrieving videos for a channel 【发布时间】：2015-07-22 21:35:21 【问题描述】：好的，所以我使用以下 php 代码尝试让 youtube 返回用户视频列表，但是，他们的“项目”显示为空。
$apiKey = "MY-API-KEY";
$channel_name = "UCSzDPMGFGxDgM4YtNM4arTA";
$count = 1;
$apiv3 = json_decode(file_get_contents("https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername=".$channel_name."&key=".$apiKey));
foreach($apiv3->items as $item):
$uploads = $item->contentDetails->relatedPlaylists->uploads;
endforeach;
$youtube = json_decode(file_get_contents("https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&contentDetails&maxResults=".$count."&playlistId=".$uploads."&key=".$apiKey));
return $youtube;
这就是返回的内容：
"kind": "youtube#channelListResponse",
"etag": "\"tbWC5XrSXxe1WOAx6MK9z4hHSU8/3cxjRXf86G9z5Bg7rup3QfCgrxM\"",
"pageInfo":
"totalResults": 0,
"resultsPerPage": 5
,
"items": [
]
然而，在他们的页面上，他们已经上传了视频。我怎样才能让它工作？我在另一个用户上使用了完全相同的代码，它工作正常。
【问题讨论】：
youtube.com/channel/UCSzDPMGFGxDgM4YtNM4arTA/videos 是他们 youtube 视频页面的链接。 您想要该频道发布的所有视频？ 是的，这就是我所希望的。 【参考方案1】：您可以改用视频搜索 API。使用带有channelId 参数的list 方法。抓住这个网址：
https://www.googleapis.com/youtube/v3/search?
part=snippet&channelId=THE_CHANNEL_ID&key=YOUR_API_KEY
响应将如下所示（从 Try It 部分复制）：
"kind": "youtube#searchListResponse",

【讨论】：
太棒了！我用的是googleapis.com/youtube/v3/activities？ part=contenDetails&channelId=THE_CHANNEL_ID&key=YOUR_API_KEY 并且它不起作用。这有效！【参考方案2】：我认为部件属性应该用逗号分隔。
$youtube = json_decode(file_get_contents("https://www.googleapis.com/youtube/v3/playlistItems?part=snippet,contentDetails&maxResults...));

【参考方案3】：@SalmanA 有一个可以使用搜索端点的答案；但是，如果您想使用 Uploads 播放列表，它也可以进行一些调整（只需通过 API 资源管理器确认）。首先，正如@SauminiNavaratnam 提到的，您的“部分”参数需要用逗号分隔。其次，当您检索频道详细信息时，您不能使用 forUsername 参数传入频道 ID。您需要使用 forUsername 参数传入 用户名，或者将频道 ID 作为 id 参数传入（请注意，您遇到的问题是 channelList 响应为空，并且因此没有任何东西可以传递给 playlistItems 调用）。如果您进行这些更改，您将获得正确的上传 ID，然后您的 playlistItems 调用将返回与搜索调用相同的结果。
但是，总而言之，您可能更喜欢搜索端点，因为它能够按日期、受欢迎程度等对结果进行排序。
