不，它与speechOutput的格式无关。问题是
request执行该方法的回调时，对它的引用
this会丢失。为了解决这个问题，请
this在调用之前保留对它的引用
request（例如，分配
this给名为的变量
self）：
'use strict';var http = require('http');var request = require('request');var Alexa = require('alexa-sdk');var APP_ID = "amzn1.ask.skill.XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX";exports.handler = function(event, context, callback) { var alexa = Alexa.handler(event, context); alexa.appId = APP_ID; alexa.registerHandlers(handlers); alexa.execute();};var handlers = { 'LaunchRequest': function () { this.emit(':tell', 'Hi!'); }, 'ApiWelcomeIntent': function () { self = this request('https://some.web/api', function (error, response, body) { if (!error && response.statusCode == 200) { // from within the callback, write data to response, essentially returning it. var speechOutput = JSON.stringify(body); console.log(body + " :Raw output?"); console.log(speechOutput + ' :JSON stringified'); console.log(response.statusCode); self.emit(':tell', speechOutput); // USE SELF HERE } else { console.log(error + ' : ' + response.statusCode); self.emit(':tell', 'There was an error'); // AND HERE AS WELL } }); }, 'AMAZON.HelpIntent': function () {} //.........And other built in intents. }};
