我通过参考基于Dialogflow的实现库的dialogflow文档,在dialogflow上创建了一个简单的聊天机器人。该机器人可以很好地与Google Assistant集成。
但是,当我开始在node.js代码中使用上下文(获取和设置上下文)时,该机器人无法在Google助手上运行。
此行agent.context.get('iotcontext');
在Google Assistant中为空,但在dialogflow测试控制台中效果很好。
以下是我的代码:
'use strict';
var https = require ('https');
const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));
function welcome(agent) {
agent.add(`Welcome to my agent!`);
}
function fallback(agent) {
agent.add(`I didn't understand`);
agent.add(`I'm sorry, can you try again?`);
}
function myIntentHandler(agent) {
console.log("Function myIntentHandler Run");
const codeContext=agent.context.get("iotcontext");
agent.add("Date spoken by user: "+codeContext.parameters["date.original"]);
}
// Run the proper function handler based on the matched Dialogflow intent name
let intentMap = new Map();
intentMap.set('Default Welcome Intent', welcome);
intentMap.set('Default Fallback Intent', fallback);
// intentMap.set('your intent name here', yourFunctionHandler);
intentMap.set('IoTIntent', myIntentHandler);
agent.handleRequest(intentMap);
});
