使用ask-sdk-core自定義技能的Alexa sdk v2失敗，原因：會話終止，原因：ERROR
[英]Alexa sdk v2 using ask-sdk-core custom skill fails with : Session ended with reason: ERROR
問題描述
我正在開發一種自定義技能，並且對此意圖有一些麻煩，也就是說，在if / else控制流中滿足所有條件的最后階段，我的意思是當它到達最后的else語句時，該命令無法返回預期的響應，但是所有返回的響應都可以正常工作，在這里我可能會遺漏什么：請密切注意resolve（handlerInput.responseBuilder.speak .... etc）的最后一部分。 我不確定我現在在做什么，我將不勝感激

終於解決了問題： 這只是我未正確處理的諾言問題 ，我不得不將一切都包裹在else語句中，這就是我如何重組最后的else語句以獲得所需的結果。
else {
return new Promise((resolve, reject) => {
let params = '';
let lookupFunc = '';
let placeNameLookup = '';
if (zipcode.length > 0 && zipCodeValidator(zipcode)) {
params = zipcode;
lookupFunc = apiCalls.zipcodeLookup;
}else {
if (state.length === 0) {
params = city;
placeNameLookup = city;
}else{
params = `${city}+${state}`;
placeNameLookup = `${city} ${state}`;
}
lookupFunc = apiCalls.placeNameLookup;
}
lookupFunc (params, (error, result, duration) => {
if(error || result === null) {
// API Call failed or result is null
speechOutput = speech.getSpeechText('error2', false);
repromtText = speech.getSpeechText('reprompt3', false);
resolove(handlerInput.responseBuilder
.speak(speechOutput)
.reprompt(repromtText)
.withSimpleCard(cardTitle, speechOutput)
.withShouldEndSession(false)
.getResponse());
}else if (Object.keys(result).length === 0) {

我如何使用alexa-sdk在我的alexa技能中使用http？
