问题出在我的PHP代码上，我收到以下错误:
码:
<?php
$feedURL2 = "https://www.googleapis.com/youtube/v3/channels?part=brandingSettings&id=UCD6YMmVyF50oiwXisgbF-2w&key=*****";
function GetytBanner() {
global $feedURL2;
$json = file_get_contents ($feedURL2);
$obj = json_decode($json,true);
return $obj['items']['image']['bannerImageUrl'];
}
?>
<?php echo GetytBanner(); ?>
最佳答案
我使用了错误的格式:
return $obj['items']['image']['bannerImageUrl'];
正确方法:
return $obj['items'][0]['brandingSettings']['image']['bannerTvHighImageUrl'];
