对话流谷歌日历集成"Error: No handler for requested intent at WebhookClient.handleRequest"

Question

我使用Fullfilment在Dialogflow中进行了Google日历集成。当我测试操作时，我在谷歌云平台中得到以下错误

Error: No handler for requested intent
at WebhookClient.handleRequest (/workspace/node_modules/dialogflow-fulfillment/src/dialogflow-fulfillment.js:317:29)
at exports.dialogflowFirebaseFulfillment.functions.https.onRequest (/workspace/index.js:62:8)
at cloudFunction (/workspace/node_modules/firebase-functions/lib/providers/https.js:57:9)
at process.nextTick (/layers/google.nodejs.functions-framework/functions-framework/node_modules/@google-cloud/functions-framework/build/src/invoker.js:100:17)
at process._tickCallback (internal/process/next_tick.js:61:11)

这是我的云功能代码-使用的意图的名称是"；book.预约"；

'use strict';
// Import the Dialogflow module from Google client libraries.
const functions = require('firebase-functions');
const {google} = require('googleapis');
const {WebhookClient} = require('dialogflow-fulfillment');

// Set up Google Calendar Service account credentials
const serviceAccountAuth = new google.auth.JWT({
email: serviceAccount.client_email,
key: serviceAccount.private_key,
scopes: 'https://www.googleapis.com/auth/calendar'
});
const calendar = google.calendar('v3');
process.env.DEBUG = 'dialogflow:*'; // enables lib debugging statements
const timeZone = 'Europe/Berlin';
const timeZoneOffset = '+02:00';
// Set the DialogflowApp object to handle the HTTPS POST request.
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
console.log("Parameters", agent.parameters);
const appointment_type = agent.parameters.AppointmentType;
function makeAppointment (agent) {
// Calculate appointment start and end datetimes (end = +1hr from start)
const dateTimeStart = new Date(Date.parse(agent.parameters.date.split('T')[0] + 'T' + agent.parameters.time.split('T')[1].split('-')[0] + timeZoneOffset));
const dateTimeEnd = new Date(new Date(dateTimeStart).setHours(dateTimeStart.getHours() + 1));
const appointmentTimeString = dateTimeStart.toLocaleString(
'en-US',
{ month: 'long', day: 'numeric', hour: 'numeric', timeZone: timeZone }
);
// Check the availability of the time, and make an appointment if there is time on the calendar
return createCalendarEvent(dateTimeStart, dateTimeEnd, appointment_type).then(() => {
agent.add(`Ok, let me see if we can fit you in. ${appointmentTimeString} is fine!.`);
}).catch(() => {
agent.add(`I'm sorry, there are no slots available for ${appointmentTimeString}.`);
});
}
// Handle the Dialogflow intent named 'book.appointment'.
let intentMap = new Map();
intentMap.set('book.appointment', makeAppointment);
agent.handleRequest(intentMap);
});
//Creates calendar event in Google Calendar
function createCalendarEvent (dateTimeStart, dateTimeEnd, appointment_type) {
return new Promise((resolve, reject) => {
calendar.events.list({
auth: serviceAccountAuth, // List events for time period
calendarId: calendarId,
timeMin: dateTimeStart.toISOString(),
timeMax: dateTimeEnd.toISOString()
}, (err, calendarResponse) => {
// Check if there is a event already on the Calendar
if (err || calendarResponse.data.items.length > 0) {
reject(err || new Error('Requested time conflicts with another appointment'));
} else {
// Create event for the requested time period
calendar.events.insert({ auth: serviceAccountAuth,
calendarId: calendarId,
resource: {summary: appointment_type +' Appointment', description: appointment_type,
start: {dateTime: dateTimeStart},
end: {dateTime: dateTimeEnd}}
}, (err, event) => {
err ? reject(err) : resolve(event);
}
);
}
});
});
}

你知道我做错了什么吗？提前感谢，Bianca

您必须在中使用"+"而不是"-"进行拆分

const dateTimeStart = new Date(Date.parse(agent.parameters.date.split('T')[0] + 'T' + agent.parameters.time.split('T')[1].split('-')[0] + timeZoneOffset));

因为您的时区偏移为"+02:00">

或者尝试将所有这些更改为：

const dateTimeStart = new Date(Date.parse(agent.parameters.date.split('T')[0] + 'T' + agent.parameters.time.split('T')[1]));

const dateTimeEnd = new Date(new Date(dateTimeStart).setHours(dateTimeStart.getHours() + 1));

const appointmentTimeString = dateTimeStart.toLocaleString(
'en-US',
{ weekday: 'short', day: 'numeric', month: 'short', hour: 'numeric', minute: 'numeric', timeZone: timeZone }
);

我希望这能奏效，因为它确实对我有用。
