替换为gdata

Question

我有一个像这样的URL，它包含在一个php文件中以查找关于视频的统计信息。

因为gdata不再有效，我应该如何做到这些？我无法在API中找到它！ （'http://gdata.youtube.com/schemas/2007'）; //获取节点的观众统计 http://gdata.youtube.com/feeds/api/videos/?q= 我不是很确定该怎么做

-old代码 - 这就是我的问题所在。我需要弄清楚这是如何用新的API编写的，

$ media = $ entry-> children（'http://search.yahoo.com/mrss/'）; //得到媒体的节点：随着新的API格式ONE本部命名为媒体信息

$attrs = $media->group->player->attributes();    // get video player URL 
$watch = $attrs['url']; 

$attrs = $media->group->thumbnail[0]->attributes();  // get video thumbnail 
$thumbnail = $attrs['url']; 

$yt = $media->children('http://gdata.youtube.com/schemas/2007'); // get <yt:duration> node for video length 
$attrs = $yt->duration->attributes(); 
$length = $attrs['seconds']; 

$yt = $entry->children('http://gdata.youtube.com/schemas/2007'); // get <yt:stats> node for viewer statistics 
$attrs = $yt->statistics->attributes(); 
$viewCount = $attrs['viewCount']; 

$gd = $entry->children('http://schemas.google.com/g/2005');  // get <gd:rating> node for video ratings 
if ($gd->rating) { 
    $attrs = $gd->rating->attributes(); 
    $rating = $attrs['average']; 
}else{$rating = 0;} 

$vid = preg_replace ('/&feature=youtube_gdata_player/','',$watch); // get video id 
$vid = substr($vid, -11);

我怎么会去再次使这项工作？

Answer 1

对于视频的统计信息，您可以要求

GET https://www.googleapis.com/youtube/v3/videos?part=statistics&id={VIDEO_ID}&key={YOUR_API_KEY} 

有关什么样的数据，你可以从视频获得更多的信息，请阅读this。

您甚至可以使用this来尝试此端点。

Answer 2

是的，那是因为您需要现在使用他们的官方API并获取您的开发人员密钥（免费）并下载php Google服务库。 https://github.com/google/google-api-php-client

这是一个例子，如何从一个视频在PHP

//You need to download these libraries 
require_once 'Google/Client.php'; 
require_once 'Google/Service/YouTube.php'; 

$client = new Google_Client(); 

$client->setDeveloperKey("YOURDEVELOPERKEYHERE"); 
$redirect = filter_var('http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'],FILTER_SANITIZE_URL); 
$client->setRedirectUri($redirect); 

// YouTube object used to make all API requests. 
$youtube = new Google_Service_Youtube($client); 

$videoIds = "a0nii7mxpFc"; //comma separated if > 1 video 

$listResponse = $youtube->videos->listVideos("id,snippet,contentDetails,statistics",array('id' => $videoIds,'maxResults'=>50)); 

$videoList = $listResponse['items'];      
foreach ($videoList as $key => $value){ 
    $video = $videoList[$key]; 
    //Here are the stats 
    echo $video['statistics']['likeCount']; 
    echo $video['statistics']['dislikeCount']; 
}
