Question

好的，所以我使用下面的php代码试图让youtube返回用户的视频列表，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，在他们的网页上，他们上传了视频。我如何让它工作？我在其他用户上使用了完全相同的代码并且工作正常。

Answer 1

您可以改用视频搜索API。将list方法与channelId参数一起使用。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",
 "etag": "\"tbWC5XrSXxe1WOAx6MK9z4hHSU8/28IrYJUKXsyiTkjfJRPDVrAyaLo\"",

Answer 2

我相信部分属性应该以逗号分隔。

$youtube = json_decode(file_get_contents("https://www.googleapis.com/youtube/v3/playlistItems?part=snippet,contentDetails&maxResults...));

Answer 3

@SalmanA有一个答案，使用可以工作的搜索终点;但是，如果您希望使用上传播放列表，它也可以进行一些调整（只是通过API资源管理器确认）。首先，正如@SauminiNavaratnam所提到的，您的“part”参数需要以逗号分隔。其次，在检索通道详细信息时，无法使用forUsername参数传递通道ID。您需要使用forUsername参数传入用户名，或者将通道ID作为id参数传递（请注意，您遇到的问题是channelList响应为空，并且因此没有什么可以传递给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调用将获得与搜索调用相同的结果。

然而，当完成所有操作后，您可能更喜欢搜索端点，因为它可以按日期，受欢迎程度等订购结果。
