Youtube API 访问权限已授予，但我仍然遇到无效凭据错误

Question

正在尝试测试 YoutubeAPI 的搜索功能，但得到了这个

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

更新：创建了新帐户，情况还是一样

好吧，我在这里做了什么：

在 console.developers.google
激活了 youtube 数据 api（选择了这样的应用程序，而不是 js 一个），已下载 json，看起来像

首先我调用 Authorize 方法（新页面显示，请求许可，我只是点击 allow 按钮，一切似乎都正常），但随后我尝试使用 Search 我收到 401 错误

代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace WebApplication3.Services.ServiceAuthoriaztion.Impl
{
    using System.Data.Entity.Core.Metadata.Edm;
    using System.IO;
    using System.Threading;
    using Google.Apis;
    using Google.Apis.Auth.OAuth2;
    using Google.Apis.Services;
    using Google.Apis.Util.Store;
    using Google.Apis.YouTube.v3;


    public class Youtube : ICustomService
    {
        private static YouTubeService _currentYouTubeService;

        public void Authorize()
        {
            UserCredential userCreds;
           ;
            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;
            }

            _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：尝试了其他类型的应用程序 - 也没有帮助。 JSON 文件看起来像这样

Answer 1

好吧，我决定一切从头开始，所以，我不知道到底是什么帮助了我，但这里有一个关于我如何让它工作的简单说明。而且，这是证明:)

所以，首先我创建了一个新项目，并为其设置了名称DanilTestApp。

其次，打开YouTube Data API那里。

当我创建新的凭据时，选择了 OAuth Client ID，然后，作为类型，选择了 Other。

准备好后我就下载了 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样

            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(

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

            RefreshToken(userCreds);

            _currentYouTubeService = new YouTubeService(new BaseClientService.Initializer
            {
                HttpClientInitializer = userCreds,

            SerachTest();

        }

            // 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");
               }

           }
       }

    }
}
