java - 缩略图上传 YouTube API v3 失败

Question

YouTube API v3 的文档非常糟糕。我已经多次报告过许多错误，但没有人使用react。我仍然必须使用此 API 来上传缩略图。该指南指出:

POST https://www.googleapis.com/youtube/v3/thumbnails/set

Auth scopes:

• https://www.googleapis.com/auth/youtubepartner
• https://www.googleapis.com/auth/youtube.upload
• https://www.googleapis.com/auth/youtube

Parameters:

• videoId: string The videoId parameter specifies a YouTube video ID for which the custom video thumbnail is being provided.

首先 - 网址错误。它必须是 https://www.googleapis.com/upload/youtube/v3/thumbnails/set。下面的代码，它使用 Unirest:

final HttpResponse<String> response = Unirest.post("https://www.googleapis.com/upload/youtube/v3/thumbnails/set")
                    .header("Content-Type", "application/octet-stream")
                    .header("Authorization", accountService.getAuthentication(account).getHeader())
                    .field("videoId", videoid)
                    .field("thumbnail", thumbnail)
                    .asString();

收到的回复:

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "required",
    "message": "Required parameter: videoId",
    "locationType": "parameter",
    "location": "videoId"
   }
  ],
  "code": 400,
  "message": "Required parameter: videoId"
 }
}

这怎么可能？ videoId 已设置!有人已经玩过这部分 API 了吗？

我可以将请求更改为

Unirest.post("https://www.googleapis.com/upload/youtube/v3/thumbnails/set?videoId=" + videoid)
                    .header("Content-Type", "application/octet-stream")
                    .header("Authorization", accountService.getAuthentication(account).getHeader())
                    .field("mediaUpload", thumbnail)
                    .asString();

这会抛出这个错误:

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "backendError",
    "message": "Backend Error"
   }
  ],
  "code": 503,
  "message": "Backend Error"
 }
}

编辑:与 Ibrahim Ulukaya 发布的 URL 相同的请求(来自引用指南的原始 URL):

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "wrongUrlForUpload",
    "message": "Uploads must be sent to the upload URL. Re-send this request to https://www.googleapis.com/upload/youtube/v3/thumbnails/set"
   }
  ],
  "code": 400,
  "message": "Uploads must be sent to the upload URL. Re-send this request to https://www.googleapis.com/upload/youtube/v3/thumbnails/set"
 }
}

Answer 1

我们解决了这个问题，如果您不想使用该库，则必须遵循以下步骤。

1) 发布 https://www.googleapis.com/upload/youtube/v3/thumbnails/set?videoId=VIDEO_ID&uploadType=resumable空空如也

2) 取回 Location: 响应头中的 URL，并使用 Content-Type: image/png 和正文中的缩略图 POST 到该 URL
