的Youtube API訪問被授權，但我仍然有憑證無效的錯誤

Question

試圖測試YoutubeAPI的搜索功能，但得到這個

難道是因爲我的頻道（這是綁定到我的Gmail帳戶中，這我目前在console.developers.google中使用）被禁止？

UPD： 創建新帳號，情況還是一樣

那麼，我在這裏做：

1. 創建，項目在console.developers.google
2. 激活YouTube數據API（應用程序選用或somth是這樣的，不是 js one），下載了json，看起來像那樣

首先我稱之爲Authorize方法（新頁面顯示，徵求許可，在這裏我只是點擊allow按鈕，一切看起來OK），但後來我試圖用Search 我得到401錯誤

繼承人的代碼

using System.Linq; 
using System.Web; 

namespace WebApplication3.Services.ServiceAuthoriaztion.Impl 
{ 
    using System.Data.Entity.Core.Metadata.Edm;

    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： 嘗試過其他類型的應用程序 - 也毫無幫助。 JSON文件看起來像

Answer 1

好吧，我決定一切從頭開始，所以，我不知道究竟是什麼幫助了我，但這裏是我如何使它運行的一個簡單的說明。而且，這裏的證明:)

所以，首先我創建新的項目，它DanilTestApp集名稱。

其次，在那裏打開YouTube Data API。

當我創建新憑據時，選擇OAuth Client ID，然後作爲類型選擇Other。

準備就緒後，我剛剛下載了JSON。

然後在我的代碼，我決定增加爽口令牌功能，所以現在它看起來像這樣

    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; 
      } 

      RefreshToken(userCreds); 

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

      SerachTest(); 

     }

      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"); 
       } 

      } 
     } 

    }
