node.js - 如果用户响应无效值，则 Azure Botframework : How to re-prompt the Prompt. 文本

Question

我有一个对话框，其中有多个提示(Prompts.text, Prompts.number, Prompts.Choice，提示.确认)。虽然 Prompts.choice 和 Prompts.confirm 似乎有内置验证，但如何验证 Prompts.text ？

我已经浏览过这个线程How to handle wrong input from the user?但通过将文本转换为选择来纠正它。

此外，我不想重新启动整个对话框，因为它会提出从那时开始的问题，如 create custom prompts to validate input 所示。

这是我的对话框的简短版本:

bot.dialog('/getDetails', [

 function (session, args, next) {

    let options = {
                retryPrompt: 'The response id invalid'
                }

      builder.Prompts.text(session, 'What is your full name?', options);
     //passing options as argument works for Prompts.choice, which seems an inbuilt validation

 },
 function (session, results, next){

     var name = session.dialogData.name;

     //How to to reprompt if user does not enters its full name?
     if (results.response) {
         name.fullname = results.response;
     }

       builder.Prompts.text(session, 'Can you please provide your country name?');  

 },
 function (session, results) {

     var name = session.dialogData.name;

     //How to reprompt only last Prompts.text if user enter an invlid value?
     if (results.response) {
         name.text = results.response;
     }

    }
 }]).triggerAction({
    matches: 'GetDetails', 
})

这是我如何通过 DialogAction.validatedPrompt 解决这个问题的

bot.dialog('/getDetail', [
    function (session) {
      session.beginDialog('/validateAge', { prompt: "What's your age?" });

      //if false response, then prmopts "I did not understand {age}""    

    },
    function (session, results) {

        if (results.response) {
            session.send("Thank you for adding your age");
        } 
    }
]).triggerAction({
     matches: /^lets validate$/i

})


bot.dialog('/validateAge', builder.DialogAction.validatedPrompt(builder.PromptType.text, function (response) {
   if(response> 0 && response < 70){

    return response;
   }
}));
