PHP YouTube API - thumbnails.set失败

我试图更新使用YouTube上的视频缩略图YouTube API,与 google-api-php-client库.我们正在上版1.0.3-beta.

我已经复制/粘贴了这个示例,并将我们client_id和client_secret我知道的值更改为了工作,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了相同的凭据).

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:这是打印出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):

我终于找到了答案.YouTube 帐户无权上传自定义缩略图(尽管可以从YouTube后端"选择"缩略图.

您可以在以下网址找到该帐户启用的功能列表:http: //www.youtube.com/features

就我而言,我需要未启用的自定义缩略图权限:

只要您的帐户信誉良好,显然验证您的YouTube帐户就会授予此权限.
