要将AWS Alexa技能与OAuth 2集成在一起,你可以按照以下步骤进行操作:
创建AWS Alexa技能:
设置OAuth 2.0授权:
编写Lambda函数:
以下是一个Node.js示例,演示了如何在AWS Lambda函数中集成Alexa技能和OAuth 2:
const Alexa = require('ask-sdk-core');
const request = require('request');
const clientId = 'YOUR_CLIENT_ID';
const clientSecret = 'YOUR_CLIENT_SECRET';
const redirectUri = 'YOUR_REDIRECT_URI';
const authorizationUrl = 'YOUR_AUTHORIZATION_URL';
const tokenUrl = 'YOUR_TOKEN_URL';
const scope = 'YOUR_SCOPE';
const LaunchRequestHandler = {
canHandle(handlerInput) {
return Alexa.getRequestType(handlerInput.requestEnvelope) === 'LaunchRequest';
},
handle(handlerInput) {
// Check if the user is already authenticated
const accessToken = handlerInput.requestEnvelope.context.System.user.accessToken;
if (!accessToken) {
// User is not authenticated, initiate OAuth 2 flow
const authorizationRequest = `${authorizationUrl}?client_id=${clientId}&response_type=code&redirect_uri=${redirectUri}&scope=${scope}`;
return handlerInput.responseBuilder
.withLinkAccountCard()
.withAskForPermissionsConsentCard([scope])
.getResponse();
} else {
// User is authenticated, continue with skill logic
return handlerInput.responseBuilder
.speak('Welcome to the skill!')
.getResponse();
}
},
};
const OAuthCallbackIntentHandler = {
canHandle(handlerInput) {
return Alexa.getRequestType(handlerInput.requestEnvelope) === 'IntentRequest'
&& Alexa.getIntentName(handlerInput.requestEnvelope) === 'OAuthCallbackIntent';
},
handle(handlerInput) {
const authorizationCode = Alexa.getSlotValue(handlerInput.requestEnvelope, 'authorizationCode');
// Exchange authorization code for access token
const tokenRequestOptions = {
url: tokenUrl,
method: 'POST',
form: {
grant_type: 'authorization_code',
code: authorizationCode,
redirect_uri: redirectUri,
client_id: clientId,
client_secret: clientSecret,
},
};
request(tokenRequestOptions, (error, response, body) => {
if (response.statusCode === 200) {
const tokenResponse = JSON.parse(body);
const accessToken = tokenResponse.access_token;
const refreshToken = tokenResponse.refresh_token;
// Store the access token and refresh token for future use
// (e.g., in a database or session)
// Continue with skill logic
const speakOutput = 'You have successfully authenticated!';
handlerInput.responseBuilder.speak(speakOutput);
} else {
const speakOutput = 'Authorization failed. Please try again.';
handlerInput.responseBuilder.speak(speakOutput);
}
return handlerInput.responseBuilder.getResponse();
});
},
};
const skillBuilder = Alexa.SkillBuilders.custom();
exports.handler = skillBuilder
.addRequestHandlers(
LaunchRequestHandler,
OAuthCallbackIntentHandler,
)
.lambda();
