c# – 使用Azure表存储的BotAuth出错

2023年10月22日 181次阅读

我正在使用
BotAuth nuget包登录我的机器人用户.最近,我按照
https://docs.microsoft.com/en-us/bot-framework/dotnet/bot-builder-dotnet-state-azure-table-storage中提到的步骤实现了Azure Table存储来存储和管理机器人的状态数据.

我的Global.asax.cs文件如下所示：

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MessagesController与bot模板中的相同：

[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)
    { ...... }
}

现在,在测试它时,我按预期获得了登录卡,在点击并完成授权过程后,我在浏览器中收到以下错误：

{
"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()"
}

我到底错过了什么？是一些autofac模块注册.有没有人有这方面的工作样本.

最佳答案 正如@FeiHan在评论中指出的那样,这是一个公开的问题,在
richdizz/BotAuth. –
“Enabling custom state service causes authentication failure”.

此问题已于MicrosoftDX/botauth修复,因此首选使用此问题
