Alexa 测试响应不包含输出语音

Question

我是Alexa的新手，并且遵循了airportinfo教程，并且我已经从github https://github.com/bignerdranch/alexa-airportinfo 复制了代码，当我使用npm对其进行测试并输入机场代码(例如SFO)时，没有"outputSpeech："，我尝试对同一问题进行类似的技能，我不确定我做错了什么。我有索引.js和FAADataInfo.js提前感谢您的帮助。

这是索引.js文件

'use strict';
module.change_code = 1;
var _ = require('lodash');
var Alexa = require('alexa-app');
var skill = new Alexa.app('airportinfo');
var FAADataHelper = require('./faa_data_helper');
skill.launch(function(req, res) {
var prompt = 'For delay information, tell me an Airport code.';
res.say(prompt).reprompt(prompt).shouldEndSession(false);
});
skill.intent('airportInfoIntent', {
'slots': {
'AIRPORTCODE': 'FAACODES'
},
'utterances': [
'{|flight|airport} {|delay|status} {|info} {|for} {-|AIRPORTCODE}'
]
},
function(req, res) {
var airportCode = req.slot('AIRPORTCODE');
var reprompt = 'Tell me an airport code to get delay information.';
if (_.isEmpty(airportCode)) {
var prompt = 'I didn't hear an airport code. Tell me an airport code.';
res.say(prompt).reprompt(reprompt).shouldEndSession(false);
return true;
} else {
var faaHelper = new FAADataHelper();
console.log(airportCode);
faaHelper.getAirportStatus(airportCode).then(function(airportStatus) {
console.log(airportStatus);
res.say(faaHelper.formatAirportStatus(airportStatus)).send();
}).catch(function(err) {
console.log(err.statusCode);
var prompt = 'I didn't have data for an airport code of ' +
airportCode;
res.say(prompt).reprompt(reprompt).shouldEndSession(false).send();
});
return false;
}
}
);
module.exports = skill;

这里是FAADataInfo.js

'use strict';
var _ = require('lodash');
var requestPromise = require('request-promise');
var ENDPOINT = 'http://services.faa.gov/airport/status/';
function FAADataHelper() {
}
FAADataHelper.prototype.getAirportStatus = function(airportCode) {
var options = {
method: 'GET',
uri: ENDPOINT + airportCode,
json: true
};
return requestPromise(options);
};
FAADataHelper.prototype.formatAirportStatus = function(aiportStatusObject) {
if (aiportStatusObject.delay === 'true') {
var template = _.template('There is currently a delay for ${airport}. ' +
'The average delay time is ${delay_time}.');
return template({
airport: aiportStatusObject.name,
delay_time: aiportStatusObject.status.avgDelay
});
} else {
//no delay
var template =_.template('There is currently no delay at ${airport}.');
return template({
airport: aiportStatusObject.name
});
}
};
module.exports = FAADataHelper;

这是我得到的回应

{
"version": "1.0",
"response": {
"directives": [],
"shouldEndSession": true
},
"sessionAttributes": {},
"dummy": "text"
}

本教程使用的 alexa 应用程序版本已过期。使用最新的 alexa-app npm 版本 (4.0.0) 时，如果运行异步函数，.intent() 函数的返回值应该是 Promise，而不是布尔值。

在索引.js中添加：

return faaHelper.getAirportStatus(....) {}.catch(){}

并在捕获后取出return false;。

这是完整的skill.intent()代码

skill.intent('airportInfoIntent', {
'slots': {
'AIRPORTCODE': 'FAACODES'
},
'utterances': [
'{|flight|airport} {|delay|status} {|info} {|for} {-|AIRPORTCODE}'
]
},
function(req, res) {
var airportCode = req.slot('AIRPORTCODE');
var reprompt = 'Tell me an airport code to get delay information.';
if (_.isEmpty(airportCode)) {
var prompt = 'I didn't hear an airport code. Tell me an airport code.';
res.say(prompt).reprompt(reprompt).shouldEndSession(false);
return true;
} else {
var faaHelper = new FAADataHelper();
console.log(airportCode);
return faaHelper.getAirportStatus(airportCode).then(function(airportStatus) {
console.log(airportStatus);
res.say(faaHelper.formatAirportStatus(airportStatus)).send();
}).catch(function(err) {
console.log(err.statusCode);
var prompt = 'I didn't have data for an airport code of ' +
airportCode;
res.say(prompt).reprompt(reprompt).shouldEndSession(false).send();
});
//return false;
}
}
);
