我正在尝试使用YouTube API检索描述或仅检索任何数据，但它似乎不适用于我>。>
我在做什么:
<?php
$unparsed_json = file_get_contents("https://www.googleapis.com/youtube/v3/videos?id=7lCDEYXw3mM&key=AIzaSyB-3Ayh1i6MlXXqWCr-NdJ07tepfalklfs&part=snippet,contentDetails,statistics,status");
$json_object = json_decode($unparsed_json, true);
?>
<html>
<head>
<title>Music Player</title>
<link rel="stylesheet" href="/resources/app.css">
</head>
<body>
<p><?php echo $json_object['items']['description']; ?></p>
</body>
</html>
API的输出:

}
我得到的错误是描述是 undefined index 。
最佳答案
请尝试以下代码:
<?php
$unparsed_json = file_get_contents("https://www.googleapis.com/youtube/v3/videos?id=7lcdeyxw3mm&key=aizasyb-3ayh1i6mlxxqwcr-ndj07tepfalklfs&part=snippet,contentdetails,statistics,status");
$json_object = json_decode($unparsed_json, true);
?>
<html>
<head>
<title>music player</title>
<link rel="stylesheet" href="/resources/app.css">
</head>
<body>
<p><?php echo $json_object['items'][0]['snippet']['localized']['description']; ?></p>
</body>
</html>
