Question

我正在尝试对用户进行身份验证，然后再继续执行其余的漫游器功能，并使用此代码确保用户存在

  [Serializable]
public class ModifyLicenceDialog: IDialog<object>
{
    private const string CreateLicence = "Create a new licence";
    private const string ModifyEndDate = "Modify end date";
    private const string CancelLicence = "Cancel a licence";

    public async Task StartAsync(IDialogContext context)
    {
        if (!CommonConversation.User.IsAuthorized)
        {
            context.Call(new AuthDialog(), ResumeAfterAuth);
        }
    }

    private async Task ResumeAfterAuth(IDialogContext context, IAwaitable<object> result)
    {
        await result;
        PromptDialog.Choice(context, ResumeAfterChoice, new[] { CreateLicence, ModifyEndDate, CancelLicence },
           "What licence function would you like?",
           "I am sorry i did not understand that, please select one of the below options");
    }

    private async Task ResumeAfterChoice(IDialogContext context, IAwaitable<string> result)
    {
        string selected = await result;

        switch (selected)
        {
            case CreateLicence:
                context.Call(new CreateLicenseDialog(), AfterLicenseDialog(CreateLicence));
                break;
            case ModifyEndDate:
                break;
            case CancelLicence:
                break;

        }
    }

    private ResumeAfter<object> AfterLicenseDialog(IDialogContext context, string licenseEvent)
    {
        switch (licenseEvent)
        {
            case CancelLicence:
                await context.PostAsync("Auth done");
                context.Done(licenseEvent);
                break;

        }
    }

然而，当我的代码进入AuthDialog时，当它尝试调用api时，如果带有提供的电子邮件的用户存在（specifically at res = await client.GetAsync(uri)），一旦api返回结果，bot会返回到父对话框（ModifyLicenceDialog））并执行ResumeAfterAuth

   [Serializable]
    public class AuthDialog: IDialog<object>
    {
        private const string InputEmail = "Please input your email address to continue.";
        private int _attempts = 3;

        public async Task StartAsync(IDialogContext context)
        {
            await context.PostAsync(InputEmail);
            context.Wait(MessageReceivedAsync);
        }  

        private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
        {
            IMessageActivity activity = await result;
            string email = activity.Text;

            await context.PostAsync("Please wait while we verify this...");

            HttpResponseMessage res = new HttpResponseMessage();
            HttpClient client = AuthFunctions.Client;

            string uri = $"api/v1/auth/licenses/{email}";

            res = await client.GetAsync(uri);

            if (res.IsSuccessStatusCode)
            {
                CommonConversation.User = JsonConvert.DeserializeObject<CustomerUser>(await res.Content.ReadAsStringAsync());
                await context.PostAsync($"Welcome {CommonConversation.User.FirstName}!");
                context.Done(email);
            }
            else if (_attempts > 0)
            {
                _attempts--;

                await context.PostAsync("I am sorry we do not recognize that email address, lets try again. Please input your email address");
                context.Wait(MessageReceivedAsync);
            }
            else
            {
                context.Fail(new Exception("I am afraid you are not an authorized user"));
            }
        }



    }
}

经过Nicolas R的一些指导后，

更新结果证明此时会抛出异常例外情况如下

{"Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host."}
"   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 SupportHelpdeskBot.Dialogs.AuthDialog.<MessageReceivedAsync>d__3.MoveNext() in C:\\Workspace\\SupportBot\\SupportHelpdeskBot\\SupportHelpdeskBot\\Dialogs\\AuthDialog.cs:line 41"

我已经尝试过System.Net.ServicePointManager.Expect100Continue = false;来阻止这种情况发生，但是这没有任何建议吗？

您的实施中没有错误：您正在使用AuthDialog完成context.Done(email)：

if (res.IsSuccessStatusCode)
{
    CommonConversation.User = JsonConvert.DeserializeObject<CustomerUser>(await res.Content.ReadAsStringAsync());
     await context.PostAsync($"Welcome {CommonConversation.User.FirstName}!");
     context.Done(email);
}

这是正常行为。你想要实现什么？我认为你的问题不完整

在api get调用之后，对话框返回到父对话框，而不是继续到当前对话框
