[英]Alexa - Accessing External API via Lambda
我正在掌握Alexa技能,需要它來查詢API,但是它似乎根本不起作用,我嘗試了100萬種不同的方法。 如果有人可以看一下下面的代碼並添加基本的API查詢,那就太好了,謝謝!
const playersOnlineHandler = {
canHandle(handlerInput) {
const request = handlerInput.requestEnvelope.request;
return (request.type === 'IntentRequest'
&& request.intent.name === 'playersOnlineIntent');
},
handle(handlerInput) {
const data =https.get("URL");
const x = "Hello";
const speechOutput = "There is currently" + data + "players online";
return handlerInput.responseBuilder
.speak(speechOutput)
.getResponse();
},
};
您可以嘗試將此代碼用於HTTP GET API調用
const playersOnlineHandler = {
canHandle(handlerInput) {
const request = handlerInput.requestEnvelope.request;
return (request.type === 'IntentRequest'
&& request.intent.name === 'playersOnlineIntent');
},
handle(handlerInput) {
let data;
const request = require("request");
let options = { method: 'GET',
url: 'http://exaple.com/api.php',
qs:
{ action: 'query' } };
request(options, function (error, response, body) {
if (error) throw new Error(error);
let json = body;
let obj = JSON.parse(json);
data = obj.element.value;
});
const x = "Hello";
const speechOutput = "There is currently" + data + "players online";
return handlerInput.responseBuilder
.speak(speechOutput)
.getResponse();
},
};
您可以參考以下代碼段。 與https
內置模塊配合使用
handle(handlerInput) {
https.get('https://jsonplaceholder.typicode.com/todos/1', res => {
res.setEncoding("utf8");
let body = "";
res.on("data", data => {
body += data;
});
//On receiving the entire info from the API
res.on("end", () => {
body = JSON.parse(body);
speechOutput += 'Sample Info' + body.userId;
return handlerInput.responseBuilder
.speak(speechOutput)
.getResponse();
});
});
},
