【问题描述】:
我正在使用 NodeJS 请求模块将 JSON 请求传递到 URL 并从中生成 JSON 响应。我尝试了这段代码,它生成了一个有效的响应。我正在粘贴我要求的 StackOverflow 问题的链接。
NodeJS Request returning an empty array inside a JSON response
但是,当我在 AWS Lambda 中使用相同的逻辑时,模块根本没有响应。由于根本没有反应,我无法理解问题所在。
这是使用 Alexa 作为触发器的 AWS Lambda 的处理函数。
'use strict';
var request = require('request');
var accountNumberRequest = {};
var balanceResponse = {};
const url = "https://ibluatapig.indusind.com/app/uat/balinq/AccountEnquiry?client_id=6867b781-9b21-45c5-9c55-948f7cd1a33f&client_secret=hP3yB3hM2oH4pH4hM1kV3uY8vR3qV7jY8cF6bG2sF5jX8lT1vN";
var bal = {};
exports.handler = function (event,context) {
try{
console.log("Try Started");
var req = event.request;
console.log("Request Generated");
if(req.type === "LaunchRequest") {
console.log("Launch Request! Calling handleLaunchRequest");
handleLaunchRequest(context);
} else if(req.type === "IntentRequest") {
console.log("IntentRequest");
let options = {};
console.log(0);
if(req.intent.name === "BalanceIntent") {
console.log("Balance Intent");
//Got the account number from Alexa request
let accNo = req.intent.slots.AccountNumber.value;
console.log(accNo);
accountNumberRequest = {
"AERequest":{
"serviceType":"BE",
"deviceId":"Test",
"accountId":accNo
}
};
console.log(accountNumberRequest);
console.log("Calling NodeJS.Request");

"content-type": "application/json",
},

},
function(error, response,body){
if(!error && response.statusCode === 200){
console.log(body.AEResponse.AcctBal[1].BalAmt);
} else {
//options.speechText = `The account <say-as interepret-as = "digits">${accNo}</say-as> does not exist`;
console.log("error: "+error);
console.log("response.statusCode"+response.statusCode);
console.log("response.statusText"+response.statusText);
}
}
);
console.log("Balance Response should be assigned by now");
console.log(bal);
/* if(accountNumbers.hasOwnProperty(accNo)) {
var balance = accountNumbers[accNo];
accountExists = true;
}
if(accountExists == true){
options.speechText = `The balance of account number <say-as interpret-as = "digits">${accNo}</say-as> is <say-as interpret-as = "cardinal">${balance}</say-as>`;
} else {
options.speechText = `The account <say-as interepret-as = "digits">${accNo}</say-as> does not exist`;
}*/
context.succeed(buildResponse(options));
}
} else if(req.type === "SessionEndedRequest") {
//Code here
} else {
throw("Unknown Intent Type");
}
} catch(e){
context.fail("Exception "+e);
}
};
function getBalance(){
//Code to parse the JSON response and extract values from the response.
}
function handleLaunchRequest(context){
//Code for handling launch requests }
function buildResponse(options){
//Code for generating response
}
【问题讨论】:
-
运行代码时看到了什么?在调试器中单步执行代码时会看到什么?
-
您在 AWS Lambda 日志中得到了什么?检查云观察。当您从中调用另一个 Web 服务时,它可能会因超时而终止(默认值:3 秒)
