Botframework 主动式机器人创建PromptDialog。选择

我有一个控制器，从另一个应用程序接收post请求

因此，我能够通过以下操作与添加了bot的用户启动对话：

ChannelAccount userAccount = new ChannelAccount();
ChannelAccount botAccount = new ChannelAccount();
IMessageActivity message = Activity.CreateMessageActivity();
userAccount = new ChannelAccount(id: "a", name: "b");
botAccount = new ChannelAccount(id: "28:...", name: "bot1");
var connector = new ConnectorClient("uriexample");
var conversationId = await connector.Conversations.CreateDirectConversationAsync(botAccount, userAccount);
message.From = botAccount;
message.Recipient = userAccount;
message.Conversation = new ConversationAccount(id: conversationId.Id);
message.ReplyToId = userAccount.Id;
message.Text = "text";
message.Locale = "en-Us";
await connector.Conversations.SendToConversationAsync((Activity)message);

这允许我在我的ApiController中向用户提示消息，而无需用户首先启动与bot的对话。接下来，我通过调用以下命令将此信息发送到另一个类：

 await Conversation.SendAsync(message, () => new Dialogs.NewDialog());

新建对话框：

[Serializable]
    public class NewDialog : IDialog<object>
    {
        public async Task StartAsync(IDialogContext context)
        {
            ChannelAccount userAccount = new ChannelAccount();
            ChannelAccount botAccount = new ChannelAccount();
            IMessageActivity message = Activity.CreateMessageActivity();
            userAccount = new ChannelAccount(id:"a", name: "b");
            botAccount = new ChannelAccount(id: "28:...", name: "bot1");
            var connector = new ConnectorClient("uriexample");
            var conversationId = await connector.Conversations.CreateDirectConversationAsync(botAccount, userAccount);

            PromptOptions<string> options = new PromptOptions<string>("Hello! yes or no?",
                "Not valid",
                "Exceeded",
                true ?
                new List<string>() { AppConstants.YesOption, AppConstants.NoFraudOption, AppConstants.ExitOption, } :
                new List<string>() { AppConstants.YesOption, AppConstants.ExitOption, },
                3);
                PromptDialog.Choice(context, this.OnOptionSelec, options);

         }

         private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
        {
            var message = await result;

            context.Wait(MessageReceivedAsync);
        }

        private async Task OnOptionSelec(IDialogContext context, IAwaitable<string> result)
        {
            try
            {
                string optionSelected = await result;

                switch (optionSelected)
                {
                    case AppConstants.YesOption:
                         context.Call(new YesDialog(), this.ResumeAfterOptionDialog);
                         break;

                    case AppConstants.NoOption:
                         context.Call(new NoDialog(), this.ResumeAfterOptionDialog);
                         break;

                    case AppConstants.ExitOption:
                         context.Call(new ExitDialog(), this.ResumeAfterOptionDialog);
                         break;
                }
            }
            catch (TooManyAttemptsException)
            {
            }
        }
    }
}

我不明白你为什么在初始化对话时包含IDialogs？顺便说一句：当您创建对话时，您应该有如下内容：

var userAccount=newchannelaccount（toId，toName）；var botAccount=新的ChannelAccount（fromId，fromName）因为有一个外部应用程序想要连接到我的bot，并且bot将广播给多个用户。对于该请求，我必须向用户提示选项。我使用IDialogs是因为在收到来自另一个应用程序的请求后，我希望将对话作为正常的机器人流程进行处理。请更好地解释流程您向用户发送了什么消息？您正在向API控制器发送消息；不适合用户。我猜你的意思是你过去做过这件事。我认为发送一个即时选择是不可能的。您必须发送消息，让用户进行交互，然后发送提示选择。在代码中，您只是创建对话，但也没有向其发送消息
