YouTube API v3 未检索频道的视频

Question

好的，所以我使用以下 php 代码尝试让 youtube 进入 return 用户视频列表，但是，他们的 "items" 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return编辑的内容：

{
 "kind": "youtube#channelListResponse",
 "etag": "\"tbWC5XrSXxe1WOAx6MK9z4hHSU8/3cxjRXf86G9z5Bg7rup3QfCgrxM\"",
 "pageInfo": {
  "totalResults": 0,
  "resultsPerPage": 5
 },
 "items": [
 ]
}

然而在他们的页面上，他们上传了视频。我如何让它工作？我在另一个用户身上使用了完全相同的代码，它工作正常。

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 URL:

https://www.googleapis.com/youtube/v3/search?
part=snippet&channelId={THE_CHANNEL_ID}&key={YOUR_API_KEY}

响应看起来像这样（从 尝试一下 部分复制）：

Answer 2

我认为部分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...));

Answer 3

@SalmanA 的答案使用了有效的搜索端点；然而，如果你想使用上传播放列表，它也可以通过一些调整来工作（刚刚用 API 浏览器确认）。首先，正如@SauminiNavaratnam 提到的，您的 "part" 参数需要以逗号分隔。其次，获取频道详情时，不能通过forUsername参数传入频道ID。您要么需要使用 forUsername 参数传入 user name，要么将频道 ID 作为 id 参数传入（请注意，您遇到的问题是 channelList 响应是空，因此没有任何内容可以传递给 playlistItems 调用）。如果您进行了这些更改，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。
