我正在使用BotAuth nuget包登錄我的機器人用戶。最近,我按照https://docs.microsoft.com/en-us/bot-framework/dotnet/bot-builder-dotnet-state-azure-table-storage中提到的步驟執行Azure Table存儲以存儲和管理機器人狀態數據。BotAuth與Azure表存儲錯誤

我的Global.asax.cs文件看起來像這樣:

public class WebApiApplication : System.Web.HttpApplication 
{ 
    protected void Application_Start() 
    { 

     var store = new TableBotDataStore(CloudStorageAccount.DevelopmentStorageAccount); 
     Conversation.UpdateContainer(builder => 
     { 

      builder.Register(c => store) 
       .Keyed<IBotDataStore<BotData>>(AzureModule.Key_DataStore) 
       .AsSelf() 
       .SingleInstance(); 

      builder.Register(c => new CachingBotDataStore(store, 
         CachingBotDataStoreConsistencyPolicy 
         .ETagBasedConsistency)) 
         .As<IBotDataStore<BotData>>() 
         .AsSelf() 
         .InstancePerLifetimeScope(); 
     }); 
     GlobalConfiguration.Configure(WebApiConfig.Register); 
    } 
} 

而且MessagesController是一樣的人在BOT模板:現在

[BotAuthentication] 
public class MessagesController : ApiController 
{ 
    /// <summary> 
    /// POST: api/Messages 
    /// Receive a message from a user and reply to it 
    /// </summary> 
    public async Task<HttpResponseMessage> Post([FromBody]Activity activity) 
    { 
     if (activity.Type == ActivityTypes.Message) 
     { 
      await Conversation.SendAsync(activity,() => new Dialogs.RootDialog()); 
     } 
     else 
     { 
      HandleSystemMessage(activity); 
     } 
     var response = Request.CreateResponse(HttpStatusCode.OK); 
     return response; 
    } 

    private Activity HandleSystemMessage(Activity message) 
    { ...... } 
} 

,在測試它,我得到如預期的登錄卡和點擊並完成授權過程後,我在瀏覽器中出現以下錯誤:

{ 
"message": "An error has occurred.", 
"exceptionMessage": "Object reference not set to an instance of an object.", 
"exceptionType": "System.NullReferenceException", 
"stackTrace": " at BotAuth.AADv1.ADALAuthProvider.<GetTokenByAuthCodeAsync>d__4.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult()\r\n at BotAuth.Controllers.CallbackController.<Callback>d__3.MoveNext()" 
} 

我錯過了什麼?它是一些autofac模塊註冊。有沒有人有任何工作示例。

能否請您發表您的消息控制器呢? – JasonSowers

加入@JasonSowers。消息控制器與bot初始模板中的相同。我沒有做任何改變。 –

我在github上發現[這個問題:「***啓用自定義狀態服務導致身份驗證失敗***」](https://github.com/richdizz/BotAuth/issues/8),你可以參考weshackett的評論和嘗試修改'CallBack控制器'以使用您配置的數據存儲。 –
