如何在Alexa中以编程方式清除自定义插槽值？ [英] How to clear custom slot value programmatically in Alexa?

问题描述

我具有Alexa技能，该技能要求以编程方式覆盖用户提供的值。

I have an Alexa skill which requires to programmatically override the values given by the user.

我尝试使该值无效，然后将其作为更新的Intent传递。

I have tried nullifying the value and later pass it in as the "updated Intent".

this.event.request.intent.userPrompt.value = null;
var updatedIntent = this.event.request.intent;
this.emit(':elicitSlot', 'userPrompt',"Say something","Say something", updatedIntent);

但是，输入JSON显示先前的值。有解决方案吗？

However, the input JSON shows previous value. Is there a solution to this?

推荐答案

有

delete this.event.request.intent.slots.<slotname>.value;
var updatedIntent = this event.request.intent;
this.emit(':elicitSlot', <slotname>,"Say something","Say something", updatedIntent);

如果您使用自定义广告位类型的广告位，也必须

if you have a slot with a custom slot type you also have to

delete this.event.request.intent.slots.<slotname>.resolutions;
