Question

尝试测试YoutubeAPI的搜索功能，但得到这个

可能是因为我的频道（绑定到我的gmail帐户，我目前在console.developers.google中使用）被禁止了吗？

UPD：创建新帐户，情况仍然相同

嗯，我在这里做了什么：

在console.developers.google
激活youtube数据api（选择这样的app或somth，而不是 js one），下载了json，看起来像那样

首先我调用Authorize方法（新页面显示，询问权限，我只点击allow按钮，一切似乎都好），但后来我尝试使用Search 我得到401错误

继承人的代码

           ;
            var filePath = string.Format("{0}{1}",AppDomain.CurrentDomain.BaseDirectory, @"App_Data\client_id.json");

                    new FileDataStore("YouTubeData")
                    ).Result;
            }

            _currentYouTubeService = new YouTubeService(new BaseClientService.Initializer
            {
                HttpClientInitializer = userCreds,
                ApplicationName = "yttest"
            });

            SerachTest();

        }

        private void SerachTest()
        {
            var searchListRequest = _currentYouTubeService.Search.List("snippet");
            searchListRequest.Q = "Google"; // Replace with your search term.
            searchListRequest.MaxResults = 50;

            // Call the search.list method to retrieve results matching the specified query term.
            var searchListResponse = searchListRequest.Execute();

            var asa = new List<string>();

        }
    }
}

UPD2：试过其他类型的应用程序 - 没有帮助。 JSON文件看起来像那样

Answer 1

好吧，我决定从头开始一切，所以，我不知道究竟对我有什么帮助，但这里有一个关于我如何使它发挥作用的简单说明。而且，这里是证明:)

所以，首先我创建了新项目，设置了它的名称DanilTestApp。

其次，在那里打开了YouTube Data API。

当我创建新凭据时，选择OAuth Client ID然后选择Other作为类型。

准备就绪后，我刚刚下载了JSON。

然后在我的代码中我决定添加刷新令牌功能，所以现在它看起来像这个

            var filePath = string.Format("{0}{1}", AppDomain.CurrentDomain.BaseDirectory, @ "App_Data\client_id.json");
            using (var stream = new FileStream(filePath, FileMode.Open, FileAccess.Read))
            {
                userCreds = GoogleWebAuthorizationBroker.AuthorizeAsync(
                 GoogleClientSecrets.Load(stream).Secrets,
                 new[] {
          YouTubeService.Scope.YoutubeReadonly
                 },
                 "user",
                 CancellationToken.None,
                 new FileDataStore("YouTubeData")
                ).Result;
            }

            RefreshToken(userCreds);

            _currentYouTubeService = new YouTubeService(new BaseClientService.Initializer
            {
                HttpClientInitializer = userCreds,
                ApplicationName = "DanilTestApp"
            });

            SerachTest();

        }

        private void SerachTest()
        {
            var searchListRequest = _currentYouTubeService.Search.List("snippet");
            searchListRequest.Q = "Google"; // Replace with your search term.
            searchListRequest.MaxResults = 50;

            // Call the search.list method to retrieve results matching the specified query term.
            var searchListResponse = searchListRequest.Execute();

            var asa = new List<string>();

        }
        //might not work, but something like this, got working code at home, office right now
        private void UpdateTokenIfExpired(UserCredential credential)
        {
           if (credential.Token.IsExpired(credential.Flow.Clock))
           {

               Console.WriteLine("The access token has expired, refreshing it");
               if (credential.RefreshTokenAsync(CancellationToken.None).Result)
               {
                   Console.WriteLine("The access token is now refreshed");
               }
               else
               {
                   throw new Exception("refresh token failed");
               }

           }
       }

    }
}

已授予Youtube API访问权限，但我仍然有“无效凭据”错误
