【问题描述】：
我需要从播放列表中嵌入 youtube 视频并显示 viewCount，播放列表项的 YouTube API v3 没有 viewCount，所以我需要使用 API v3 为视频执行另一个查询，它提供统计 viewCount 但需要在查询中添加一个逗号分隔的 YouTube 视频 ID 列表
https://www.googleapis.com/youtube/v3/videos?part=statistics&id='.$listofvideoIDfromPlaylistItems.'&key={YOUR_API_KEY}
这就是我为playlistItems 准备的内容
public function loadPlaylist($maxVideos){
if($this->_key && $this->_playlist) {
$this->_url = filter_var(
$this->_apiUrl.'playlistItems?part=id,snippet,contentDetails,status&maxResults='.$maxVideos.'&playlistId='.$this->_playlist.'&key='.$this->_key,
FILTER_SANITIZE_URL
);
$curlObj = curl_init();
curl_setopt($curlObj, CURLOPT_URL, $this->_url);
curl_setopt($curlObj, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($curlObj, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curlObj, CURLOPT_HTTPGET, true);
curl_setopt($curlObj, CURLOPT_HTTPHEADER, array('Content-type:application/json','Accept: application/json'));
curl_setopt($curlObj,CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($curlObj);
curl_close($curlObj);
$json = json_decode($response, true);
print("<pre>".print_r($json['items'],true)."</pre>");
}
return FALSE;
}
print_r 给了我
Array

[kind] => youtube#playlistItem
[etag] => "xxx"

如何创建以逗号分隔的 videoID？
经过大量阅读:)
这就是我的结局
public static function getVideos($params) {
$key = $params->get('apiKey');
$list = $params->get('playlistID');
$maxVideos = $params->get('maxVideos');
if($key && $list){
function get_data($url)
{
$ch = curl_init();
$timeout = 5;
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPGET, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json','Accept: application/json'));
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$apiPlaylist = get_data("https://www.googleapis.com/youtube/v3/playlistItems?part=id,snippet,contentDetails,status&maxResults=".$maxVideos."&playlistId=".$list."&key=".$key."");
$video = json_decode($apiPlaylist);
$video2 = json_decode($apiPlaylist);
//To display video statistics viewCount
foreach ($video2->items as $statsitem) {
$videoids = $statsitem->contentDetails->videoId. ",";
$apiVideostats = get_data("https://www.googleapis.com/youtube/v3/videos?part=id,statistics&id=".$videoids."&key=".$key."");
$stats = json_decode($apiVideostats);
var_dump($stats->items);
}
$videolist = array();
//To display embed code, title and description
foreach ($video->items as $videoitem) {
$videolist[] = $videoitem;
}
return $videolist;
}
return false;
}
$stats->items var_dump 返回
array (size=1)
0 =>
object(stdClass)[686]
public 'kind' => string 'youtube#video' (length=13)
public 'etag' => string '"xxx"' (length=57)
public 'id' => string 'xxx' (length=11)
public 'statistics' =>
object(stdClass)[687]
public 'viewCount' => string '465' (length=3)
public 'likeCount' => string '1' (length=1)
public 'dislikeCount' => string '0' (length=1)
public 'favoriteCount' => string '0' (length=1)
public 'commentCount' => string '0' (length=1)
array (size=1)
0 =>
object(stdClass)[690]
public 'kind' => string 'youtube#video' (length=13)
public 'etag' => string '"xxx"' (length=57)
public 'id' => string 'xxx' (length=11)
public 'statistics' =>
object(stdClass)[691]
public 'viewCount' => string '439' (length=3)
public 'likeCount' => string '2' (length=1)
public 'dislikeCount' => string '0' (length=1)
public 'favoriteCount' => string '0' (length=1)
public 'commentCount' => string '1' (length=1)
如何组合 2 个 foreach 循环或者我这样做是否正确？
