php - 如何在 php 中使用 Youtube Api 获取 YouTube 视频描述和评论

Question

我正在做一个 YouTube 项目，我正在通过 RSS 从 YouTube 获取数据，我只使用 RSS 获取标题，现在我想获取该特定视频的描述和评论。我尝试了很多方法，但没有一个对我有用，除了一种，但它没有给我描述和评论，它只是返回我的名字、高度宽度、视频 url、作者等
我尝试过的代码如下
此代码正在运行，但没有返回我需要的内容

$youtube = "http://www.youtube.com/oembed?url=". $src_url_r ."&format=json";
$curl = curl_init($youtube);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$return = curl_exec($curl);
curl_close($curl);
$tst = json_decode($return, true);

我尝试过但不工作的其他代码是

$id = substr(get_post_meta(get_the_ID(), 'rss_pi_source_url', TRUE), strrpos(get_post_meta(get_the_ID(), 'rss_pi_source_url', TRUE), '=') + 1);

        //echo "https://gdata.youtube.com/feeds/api/videos/".$id."?v=2&alt=json";
        $json_output = file_get_contents("http://gdata.youtube.com/feeds/api/videos/".$src_url."?v=2&alt=json");
        $json = json_decode($json_output, true);

        //This gives you the video description
        $video_description = $json['entry']['media$group']['media$description']['$t'];

        //This gives you the video views count
        $view_count = $json['entry']['yt$statistics']['viewCount'];

        //This gives you the video title
        $video_title = $json['entry']['title']['$t'];

这是另一段不起作用的代码

$json_output = file_get_contents("https://www.googleapis.com/youtube/v3/videos?part=snippet&id=0KNk-Joi-NM&key=my_api_key");
            $json = json_decode($json_output, true);
            print_r($json);

请任何人指导我

Answer 1

首先把你的

https://www.googleapis.com/youtube/v3/videos?part=snippet&id=0KNk-Joi-NM&key=my_api_key

在您的浏览器中，看看您是否得到正确的响应。如果您的 key 未显示以下内容，请检查您的 key 凭据。用我的 key 在这里工作正常。
