php - 如何使用PHP从YouTube数据API访问统计信息

我正在运行一个PHP脚本，该脚本使用channelId从YouTube channel 检索视频。

$API_key    = 'MY_KEY';
$channelID  = 'MY_CHANNEL_ID';
$maxResults = 2;

$videoList = json_decode(file_get_contents('https://www.googleapis.com/youtube/v3/search?order=date&part=snippet&channelId='.$channelID.'&maxResults='.$maxResults.'&key='.$API_key.''));

然后，我将其插入网页中:

<iframe width="280" height="150" src="https://www.youtube.com/embed/'.$item->id->videoId.'" frameborder="0" allowfullscreen></iframe>
                        <h2>'. $item->snippet->title .'</h2>
                        <h2>'. $item->snippet->publishedAt .'</h2>
                        <h2>'. $item->statistics->duration .'</h2>

我似乎无法访问json文件的统计信息部分。当我打印json时，它看起来像这样:

stdClass Object
(
    [kind] => youtube#searchListResponse
    [etag] => "XI7nbFXulYBIpL0ayR_gDh3eu1k/n6hG3LC-2onr-

                        [thumbnails] => stdClass Object
                            (
                                [default] => stdClass Object
                                    (
                                        [url] => https://i.ytimg.com/vi/YxjEmz6KWdU/default.jpg

                                        [height] => 90
                                    )

                                [medium] => stdClass Object
                                    (
                                        [url] => https://i.ytimg.com/vi/YxjEmz6KWdU/mqdefault.jpg
                                        [width] => 320
                                        [height] => 180
                                    )

                                [high] => stdClass Object
                                    (
                                        [url] => https://i.ytimg.com/vi/YxjEmz6KWdU/hqdefault.jpg
                                        [width] => 480
                                        [height] => 360
                                    )

                            )

                        [channelTitle] => Fernanfloo
                        [liveBroadcastContent] => none
                    )

            )

    )

)

因此，显然json文件并不包含所有信息。我相信这是网址的问题。它只是创建带有一些信息的json文件。我尝试将url和不同的路径切换为持续时间。

$videoList = json_decode(file_get_contents('https://www.googleapis.com/youtube/v3/search?order=date&part=snippet&channelId='.$channelID.'&maxResults='.$maxResults.'&key='.$API_key.''));

我是YouTube Data API的新手，但我的知识参差不齐。有人可以解释我做错了吗？

最佳答案

您需要修改API请求，以便在statistics参数中添加part。

另外，您使用的是“搜索”选项-根据其documentation，它不会显示statistics值(这是您所需要的)。

因此，您必须使用“videos”选项。

这是您可以使用的修改后的API请求:

https://www.googleapis.com/youtube/v3/videos?id=YxjEmz6KWdU&maxResults=2&part=snippet%2Cstatistics&key=<YOUR_API_KEY>

以下信息来自YouTube Data API - official documentation:

id:您要检索statistics的YouTube视频的ID。

密钥:您的API密钥。

部分:参数part指定一个API响应将包括的一个或多个搜索资源属性的逗号分隔列表。对于这种情况，我添加了snippet和 statistics 。

该视频的统计信息将显示在API响应的statistics部分中。

这是使用try-it functionality并指定videoId YxjEmz6KWdU得出的结果:
