Question

我有一个Alexa技能，需要以编程方式覆盖用户给出的值。

我尝试使值无效，然后将其作为“更新的Intent”传递。

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显示以前的值。有解决方案吗？

Answer 1

有

 WebElement  elem = driver.findElement(By.id("summaryTable"));

    List<WebElement> lists = elem.findElements(By.tagName("th"));

    for(WebElement el : lists){

        WebElement element = el.findElement(By.tagName("a"));

        String  str = element.getAttribute("innerHTML");
        System.out.println(str);

    }

如果您有自定义插槽类型的插槽，则还必须

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

对于版本V2，您应该以这种方式（据我所知）更新意图

 handlerInput.responseBuilder
    .addDelegateDirective(newIntent)
    .getResponse();

如何在Alexa中以编程方式清除自定义插槽值？
