下载标题总是返回403

Question

当我captions.download使用从captions.list端点检索的ID 调用端点时,它总是返回403.例如:

https://www.youtube.com/watch?v=1HRwpwOj4aA

我打电话captions.list给:

GET https://www.googleapis.com/youtube/v3/captions?part=id&videoId=1HRwpwOj4aA&key={YOUR_API_KEY}

这是回应:

{
 "kind": "youtube#captionListResponse",
 "etag": "\"dhbhlDw5j8dK10GxeV_UG6RSReM/Rztb3ln4Zb6O07vb7_KSZi2y1NM\"",
 "items": [
  {
   "kind": "youtube#caption",

   "id": "kHlUsiuNS4TjB25loauZNXGrjK91I1tEdNyOpTRNA78="
  }
 ]
}

当我使用上面的id来调用captions.download:

GET https://www.googleapis.com/youtube/v3/captions/kHlUsiuNS4TjB25loauZNXGrjK91I1tEdNyOpTRNA78%3D?key={YOUR_API_KEY}

这是回应:

Forbidden

有什么想法可以在这里发生吗？

Answer 1

状态 403 禁止表示任何人都无权访问该 URL。例如，如果您的 API 密钥错误，您就不会收到该消息；这应该给出 Status 401 Unauthorized。我会仔细检查网址。
