PHP YouTube API – thumbnails.set失败

我已经复制/粘贴了example,并将我们的client_id和client_secret更改为我知道工作的值,因为我现在仍然可以使用这些值上传视频,我只是无法设置缩略图(我刚刚上传的视频)使用相同的凭据).

这是我得到的错误：

An client error occurred: Error calling PUT https://www.googleapis.com/upload/youtube/v3/thumbnails/set?videoId=wL3Rt0sokdI&uploadType=resumable&upload_id=AEnB2UqFI4w1qO1gjoFS-fOlc61OthOht0ngdFAcdG9Nnufds61IyMIUUxf1rAvmoDl77LeEQZb1-HMyqtc9Op3Jg4hRfcyuOQ: (403) Forbidden

编辑 – 更多信息：这是我在打印完整个异常时获得的一小部分信息：

{
    ["errors":protected]=> array(1) 
    {
        [0]=> array(5) { 
            ["domain"]=> string(17) "youtube.thumbnail" 
            ["reason"]=> string(9) "forbidden" 
            ["message"]=> string(9) "Forbidden" 
            ["locationType"]=> string(6) "header" 
            ["location"]=> string(13) "Authorization" 
    } 
}

这是我正在使用的脚本(它与示例代码相同,但我将它放在这里,以防上面的示例URL出现故障)：
