php – Google Drive API缩略图参数

2023年7月21日 331次阅读

我正在使用Google Drive API(v3)与Google的
PHP api客户端列出并显示来自我的云端硬盘的视频,其中我还显示了所述视频的缩略图.虽然我在请求参数中启用了thumbnailLink,但我很难从API中获取缩略图网址：

'fields' => 'nextPageToken, files(id, name, thumbnailLink, webContentLink, webViewLink)'

thumbnailLink的值仍为空,其他值成功返回.我在api文档中查找缩略图设置,但没有成功. API也不会返回任何错误.会是什么呢？

这是我正在使用的代码：

$drive_service = new Google_Service_Drive($client);

$optParams = array(
'pageSize' => 4,
'q' => "'0B_nSMgQioOWwNy1ha0tFWEE0QWs' in parents and mimeType contains 'video/'",
'fields' => 'nextPageToken, files(id, name, modifiedTime, mimeType, createdTime, thumbnailLink, webContentLink, webViewLink)'
);

return $files_list = $drive_service->files->listFiles($optParams)->getFiles();

和响应的var_dump

最佳答案 尝试仔细检查您是否正确使用了正确的范围.我建议您使用https://www.googleapis.com/auth/drive获取完全许可范围来访问所有用户的文件.如果仍然无法正常工作,请尝试建议的解决方案
