botFramework:在bot框架下禁用Web聊天中的卡按钮

Question

我想在bot框架下禁用网络聊天中的卡片按钮.例如,在一张卡片我有多个按钮,我想根据一些数据值禁用一些按钮.我怎样才能做到这一点？

Answer 1

在将来,我建议缩小您的要求,使其不那么广泛,并包含与您要实现的目标相关的详细信息.尽管如此,我已经填补了一些空白并做了一些我希望会有所帮助的事情.:)

我有一个工作示例机器人,执行以下操作:

• 每个响应显示一张英雄卡片
• 如果用户说'hi'或'hello',卡上会显示两个按钮
• 如果用户没有问候机器人,只会显示一个按钮.
• 告诉用户他们是否与机器人打交道(SendGreeting,true或false)

我在UserData,SendGreeting中保存了一个布尔值,通知机器人是否显示第二个按钮.在控制器中,我有以下代码:

• 实例化UserData,
• 确定SentGreeting是true还是false

• 然后将该布尔值保存到UserData.SentGreeting.

           // create connector service
          ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));
          // get state client object
          StateClient stateClient = activity.GetStateClient();
          // retrieve user data
          BotData userData = await stateClient.BotState.GetUserDataAsync(activity.ChannelId, activity.From.Id);
  
          bool SentGreeting;
          if (activity.Text == "hello" || activity.Text == "hi")
          {
              SentGreeting = true;
          } else
          {
              SentGreeting = false;
          }
          userData.SetProperty<bool>("SentGreeting", SentGreeting);
  
          // save state
          await stateClient.BotState.SetUserDataAsync(activity.ChannelId, activity.From.Id, userData);
  
          // initiate CardDialog
          await Conversation.SendAsync(activity, () => new CardDialog());
  

在对话框中,有以下代码:

• 从UserData检索SentGreeting
• 创建英雄卡

• 只有在SentGreeting为true时,才会创建秘密按钮并将其添加到按钮列表中

          // create sentGreeting
      bool sentGreeting;
      // assign value from UserData.SentGreeting
      context.UserData.TryGetValue<bool>("SentGreeting", out sentGreeting);
  
      // create standard button list (for those who do not greet the bot)
      var GenericButtonList = new List<CardAction>
      {
          new CardAction(ActionTypes.OpenUrl, "Bot Framework", value: "https://docs.botframework.com/en-us/"),
      };
  
      // create the hero card
      var Card = new HeroCard()
      {
          Title = "Select an Action",
          Subtitle = "Choose from available actions",
          Text = "If you were polite and said \'hi\' or \'hello\' to this bot, you will see two buttons below.",
          Images = new List<CardImage> { new CardImage("https://cloud.githubusercontent.com/assets/14900841/23733811/c618e402-042f-11e7-9b8e-6262d9f2d898.JPG") },
          Buttons = GenericButtonList
      };
      // create secret button that only users who said hi can see
      CardAction secretButton = new CardAction();
      secretButton.Title = "Very Polite";
      secretButton.Type = "openUrl";
      secretButton.Value = "https://github.com/Microsoft/BotBuilder-Samples/tree/master/CSharp/demo-ContosoFlowers/ContosoFlowers.Services";
  
      if (sentGreeting)
      {
          Card.Buttons.Add(secretButton);
      }
