YouTube注释API:注释插入403权限不足

这就是我用来向youtube添加评论的方法:

This is what im using to add comments to youtube :

gapi.client.youtube.commentThreads.insert({
          part: "snippet", commentData
        }).then(function (response) {
          console.log("response", response);
    })

这就是我被击中时得到的:

This is what im getting while hit that :

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "insufficientPermissions",
    "message": "Insufficient Permission: Request had insufficient authentication scopes."
   }
  ],
  "code": 403,
  "message": "Insufficient Permission: Request had insufficient authentication scopes."
 }
}
