swift - 列出我的 YouTube 播放列表时出错

Question

我通过 Google 登录 iOS SDK 获得了我的用户访问 token 。 然后我使用以下源代码在 YouTube 中获取我的播放列表:

func listMyPlaylists(completionHandler: @escaping (_ result: Any?, _ error: Error?) -> ())
{
    let url = URL(string: "https://www.googleapis.com/youtube/v3/playlists")!
    let parameters: Parameters = ["part": "id","mine": "true"]
    let headers: HTTPHeaders = ["Authorization": "Bearer " + accessToken, "Content-Type": "application/json"]

    Alamofire.request(url, method: .get, parameters: parameters, encoding: URLEncoding.default, headers: headers).responseJSON { json in

        if let error = json.result.error
        {
            completionHandler(nil, error)
        }
        else
        {
            completionHandler(json.result.value, nil)
        }
    }
}

但是，我收到以下错误。我想念什么？

{
error =     {
    code = 403;
    errors =         (
                    {
            domain = global;
            message = "Insufficient Permission";
            reason = insufficientPermissions;
        }
    );
    message = "Insufficient Permission";
};

Answer 1

这通常发生在您未包括 Youtube API Common request errors 中所述的授权范围时

forbidden (403) - insufficientPermissions The OAuth 2.0 token provided for the request specifies scopes that are insufficient for accessing the requested data.

Youtube scopes 之一你可以使用

https://www.googleapis.com/auth/youtube.force-ssl
