我只有一个dialog，其中有多个提示（Prompts.text，Prompts.number，Prompts.Choice，Prompts.confirm）。虽然Prompts.choice和Prompts.confirm似乎具有内置的验证，但是如何验证Prompts.text？
我已经通过了该线程How to handle wrong input from the user?，但已通过将文本转换为选择而得到纠正。
另外，我也不想重新启动整个对话框，因为它会从create custom prompts to validate input所示开始询问问题表单。
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',
})
最佳答案
这是我通过DialogAction.validatedPrompt解决问题的方法
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;
}
}));
