I am trying to build up a facebook messenger chatbot using Dialogflow. In the dialogflow fulfillment inline editor, I found that I can use agent.request_.body to get the body of the request. I assume "request_" is a property of WebhoodClient object? But I couldn't find any documentation elaborate that, could you please advise if my understanding is correct and where I can find the reference or documentation?
const agent = new WebhookClient({ request, response });
console.log(JSON.stringify(agent.request_.body));
Thanks
Google provides documentation for Dialogflow webhooks here, which include this sample webhook to inspect parameters and dynamically create slot filling prompts:
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
function flight(agent) {
const city = agent.parameters['geo-city'];
const time = agent.parameters['time'];
const gotCity = city.length > 0;
const gotTime = time.length > 0;
if(gotCity && gotTime) {
agent.add(`Nice, you want to fly to ${city} at ${time}.`);
} else if (gotCity && !gotTime) {
agent.add('Let me know which time you want to fly');
} else if (gotTime && !gotCity) {
agent.add('Let me know which city you want to fly to');
} else {
agent.add('Let me know which city and time you want to fly');
}
}
let intentMap = new Map();
intentMap.set('flight', flight);
agent.handleRequest(intentMap);
});
My guess would be to add
console.log(agent);
right before defining the flight function, then checking the logs to see which objects agent contains, then adding iterations of console.log(agent.fakeObjectName) until you find the information you're looking for.
If you're following the deployment process recommended in Actions on Google's Codelabs level 2, your logs will show up in the Firebase console, like this:
Hope that helps!
Just a note.
I had a code similar to this:
const city = agent.parameters['geo-city'];
There is an icon that suggest it's better written in dot notation.
that is gone after I changed it to:
const city = agent.parameters.geo-city;

I am trying to save the data through the conversation with user.storage, I am accessing the user.storage like this:
app.post('/', express.json(), (req, res) => {
const agent = new WebhookClient({ request: req, response: res })
let personalD=new personalDetails(agent)
function personal_details(){
personalD.foo()
}
let intentMap = new Map()
intentMap.set('inform.PersonalDetails',personal_details)
agent.handleRequest(intentMap)
}
//that's the personalDetails class:
class PersonalDetails{
constructor(agent){
this.agent=agent;
this.conv=this.agent.conv();
}
foo() {
this.conv.user.storage.name=this.agent.parameters.name;
this.conv.user.storage.age=this.agent.parameters.age;
this.conv.user.storage.gender=this.agent.parameters.gender;
const gotname = this.conv.user.storage.name==''?0:1
const gotage = this.conv.user.storage.age==''?0:1
const gotgender =this.conv.user.storage.gender==''?0:1
const name=this.conv.user.storage.name;
const gender=this.conv.user.storage.gender;
if (gotname && !gotage&&!gotgender)
this.agent.add(`Ok, ${name}, How old are you? and what is you'r gender?`)
else if (gotname && gotage&&!gotgender)
this.agent.add(`Ok, ${name}, What gender you belong to`)
else if(gotname && !gotage&&gotgender)
this.agent.add(`Ok, ${name}, How old are you?`)
else if (!gotname && gotage&&gotgender)
this.agent.add(`What's your name please?`)
else if (!gotname && !gotage&&gotgender)
this.agent.add(`Well dear ${gender}, What is your name and how old are you`)
else if(!gotname && gotage&&!gotgender)
this.agent.add('Let me know what is your name and what is your gender')
else if (!gotname && !gotage&&!gotgender)
this.agent.add(`I want to get to know you before we begin. what is you'r name?`)
}
}
module.exports=PersonalDetails;
Dialogflow wants from the user three entites: name, age and gender. When the user does not provide all of them the code does some logic to see what is missing.
The problem is that at first I enter lets say name and age, and then it asks the user about the gender, when the user enteres the gender it's already forgetting the name and the age...
please help
In your dialogflow fulfillment code, you are initializing parameters in user.storage on every request from the intent, instead of only when you have a value from the user. This code is your problem:
this.conv.user.storage.name=this.agent.parameters.name;
this.conv.user.storage.age=this.agent.parameters.age;
this.conv.user.storage.gender=this.agent.parameters.gender;
You have to set the user.storage only once and then, you can use it anywhere directly.
app.intent('GetUserName', (conv, {name}) => {
conv.user.storage.name= name;
conv.ask(`Hi, ${conv.user.storage.name}!.
Please tell me how can I help you? `);
});
app.intent('AboutSC', (conv) => {
conv.ask(`well ${conv.user.storage.name}. What more would you like to know? `);
});
You can use the user.storage parameters directly. But using variable/constants that are initialized on every request will change the value everytime & will not help.
I'm developing a chat bot for Telegram using DialogFlow, but I can't go through two topics, and I can't find the documentation for them.
The flow of the conversation, is the user answer some closed questions and send an image.
How do I get this image?
And to save her along with the other answers?
The answers need to be saved as a form/survey and not as a conversation history.
I have a similar setup in my chatbot. I store the answers in a Firebase database.
In order to interact with the Firestore Database you should implement a Fulfillment
You can see a guide on how to implement Firebase for DialogFlow here
Here you can see a sample of my code. In general lines after setting up the connection to the Firebase database you just want to map your intents to your functions using intentMap.set.
As you said you are using closed answers you can set intets to handle the responses and each "final" intent will trigger a different function that will write a different message to the db.
To write the response to the Firesbase database you just only need to implement admin.database().ref().push().set({}) with the information and the desired structure.
In my example I also store the conversation Id from the chat payload and the date.
'use strict';
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
//const DialogflowApp = require('actions-on-google').DialogflowApp;
process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements
admin.initializeApp({
credential : admin.credential.applicationDefault(),
databaseURL: 'ws://YOURDATABASE.firebaseio.com/'
});
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));
var userId;
let conv = agent.conv();
const ROOTREF = admin.database().ref();
const actions = new Map();
let intentMap = new Map();
intentMap.set('Default Fallback Intent', fallback);
intentMap.set('NoTunel', handleWriteToDbNoTunnel(agent));
agent.handleRequest(intentMap);
function assignConv(agent){
userId = agent.parameters.UserId;
return admin.database().ref('Users/'+ userId).set({
Apellido:"XXXX",
Nombre:"XXXX",
chatId:333,
});}
function fallback(agent) {
agent.add(`I didn't understand`);
agent.add(`I'm sorry, can you try again?`);
}
var token = "YOUR TOKEN HERE";
var url = "https://api.telegram.org/bot"+ token;
function handleWriteToDbNoTunnel(agent){
const Dia = new Date();
if(matricula !== "")
return admin.database().ref('Limpieza/').push().set({
chatId: request.body.queryResult.outputContexts[3].parameters.telegram_chat_id+'"',
Field1: answer1,
Field2: answer2,
day: day.getTime()
});
}
});
Also if you want to store images with the user responses you can implement the getfile method from the telegram api and store the image code or the image itself
I am adding this answer to slightly improve on Chris32's answer.
There is a better way to get the value of the Telegram Chat ID as I am using it in a personal project.
I will go end to end to explain my approach.
I have mapped some files to some specific intents. In my intent-mapper.js file, I have mapped Default Welcome Intent to welcome.js file as prescribed in the documentation for the Dialogflow Fufillment library for NodeJS (Please note that the library is deprecated and not being updated, personally I am using a fork of the repo that I have worked on personally).
const intentMap = new Map();
intentMap.set('Default Welcome Intent', welcome);
.
.
Then, in welcome.js,
const globalParameters = {
'name': 'global-parameters',
'lifespan': 9999,
'parameters': {}
};
globalParameters.parameters.telegramChatId = agent.originalRequest?.payload?.data?.chat?.id || -1;
.
.
agent.setContext(globalParameters);
The telegramChatId variable in the global parameters context will save the value for the chat ID which can be passed to a helper function to send a message. In order to to retrieve the value from the global parameters, the code snippet is this.
const globalParameters = agent.getContext('global-parameters');
const telegramChatId = globalParameters.parameters.telegramChatId;
Then the Telegram message helper function is largely the same as in Chris32's answer. The message can be any string and chatId can be passed as an argument to the following helper function.
const TelegramBot = require('node-telegram-bot-api');
const { telegramBotToken } = process.env.TELEGRAM_BOT_TOKEN;
const bot = new TelegramBot(telegramBotToken, { polling: false });
const sendTelegramTextMessage = (message, chatId) => {
try {
bot.sendMessage(chatId, message, {parse_mode: 'html'});
} catch (err) {
console.log('Something went wrong when trying to send a Telegram notification', err);//remove console.log()
}
};
The reason I have put this all in a context since in my use case I am sending push notifications via Telegram once the user asks for it (this happens later in the conversation flow), so I have implemented it this way. The main point to note is that the agent object already has the detectIntentRequest variable saved inside it which in turn has the value we need as a part of its payload. Here's a snippet of the same.
Please note I have removed many lines from my code for brevity, but in a nutshell, the chat ID can be accessed from
agent.originalRequest?.payload?.data?.chat?.id
And the value for the telegram bot token is a secret value which can be saved in an environment variable or Secrets Manager. Please note my answer explains a better way to retrieve the chat ID without needing to refer directly to the request object since Dialogflow Fulfillment library already caches the value in the body for us. The other stuff for receiving and sending images is explained in the main answer.
I am using Dialogflow nodejs SDK(V2) to Integrate Dialogflow in my nodjs application for that I am using dialogflow npm node library. I'm able to create the Intent and get the list of Intents and I'm able to query as well. But I can't find any method for updating the existing Intent and getting Intent details based on the Intent ID.
can you please help me or guide me how to resolve this issue?
Thanks.
To update an intent, first, you need to get the intent details. If you have the intent name or ID, then you can simply make a request to list intent API and find the intent details with matching intent name.
Once you have the intent details you wish to update( here referred as existingIntent), you can use the below code to update it.
async function updateIntent(newTrainingPhrases) {
// Imports the Dialogflow library
const dialogflow = require("dialogflow");
// Instantiates clients
const intentsClient = new dialogflow.IntentsClient();
const intent = existingIntent; //intent that needs to be updated
const trainingPhrases = [];
let previousTrainingPhrases =
existingIntent.trainingPhrases.length > 0
? existingIntent.trainingPhrases
: [];
previousTrainingPhrases.forEach(textdata => {
newTrainingPhrases.push(textdata.parts[0].text);
});
newTrainingPhrases.forEach(phrase => {
const part = {
text: phrase
};
// Here we create a new training phrase for each provided part.
const trainingPhrase = {
type: "EXAMPLE",
parts: [part]
};
trainingPhrases.push(trainingPhrase);
});
intent.trainingPhrases = trainingPhrases;
const updateIntentRequest = {
intent,
languageCode: "en-US"
};
// Send the request for update the intent.
const result = await intentsClient.updateIntent(updateIntentRequest);
return result;
}
I have a dialogflow assistant app with 3 intents. The first intent asks the user for location and name details from google. I am using a webhook for the fulfillment of this intent. I am able to extract the user information name and location, but after it is showing output from webhook, it is exiting from flow. But it is supposed to pass the location parameters to next intent and stay on the flow. Can anybody help me how to stop assistant from exiting?
Here is the webhook code
'use strict';
const functions = require('firebase-functions');
const DialogflowApp = require('actions-on-google').DialogflowApp;
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const requestPermission = (app) => {
app.askForPermissions('To report ', [app.SupportedPermissions.NAME, app.SupportedPermissions.DEVICE_PRECISE_LOCATION]);
};
const userInfo = (app) => {
if (app.isPermissionGranted()) {
const address = app.getDeviceLocation().coordinates;
const name = app.getUserName().givenName;
if (name) {
app.tell(`You are name ${name}`);
}
else {
// Note: Currently, precise locaton only returns lat/lng coordinates on phones and lat/lng coordinates
// and a geocoded address on voice-activated speakers.
// Coarse location only works on voice-activated speakers.
app.tell('Sorry, I could not figure out where you are.Plaese try again');
}
} else {
app.tell('Sorry, I could not figure out where you are.Please try again');
}
};
const app = new DialogflowApp({request, response});
const actions = new Map();
actions.set('request_permission', requestPermission);
actions.set('user_info', userInfo);
app.handleRequest(actions);
});
The problem is that you are calling app.tell() in your code which is a signal to the Assistant to send the message and then end the conversation.
If you want to send the message and then leave the microphone open for the user to reply, you should use app.ask() instead. It takes the same parameters - the only difference is that it expects the user to reply.
So that portion of your code might look something like
if (name) {
app.ask(`You are name ${name}. What would you like to do now?`);
}
(You should make sure that the prompt for the user is one that they will expect to reply. The review process will reject your Action if you reply and it isn't obvious that the user is supposed to reply to you.)
I am building an app using Dialogflow. The user answers some questions, and can review their answers later. My problem is with building the server to return the user's previous answers.
This is the code so far, where the intents are QUESTION_1 and QUESTION_2, and the parameters are GRATEFUL_1 and GRATEFUL_2:
'use strict';
process.env.DEBUG = 'actions-on-google:*';
const App = require('actions-on-google').DialogflowApp;
const functions = require('firebase-functions');
// a. the action names from the Dialogflow intents
const QUESTION_1 = 'Question-1';
const QUESTION_2 = 'Question-2';
// b. the parameters that are parsed from the intents
const GRATEFUL_1 = 'any-grateful-1';
const GRATEFUL_2 = 'any-grateful-2';
exports.JournalBot = functions.https.onRequest((request, response) => {
const app = new App({request, response});
console.log('Request headers: ' + JSON.stringify(request.headers));
console.log('Request body: ' + JSON.stringify(request.body));
// Return the last journal entry
function reflect (app) {
let grateful_1 = app.getArgument(GRATEFUL_1);
app.tell('Here is your previous entry: ' + grateful_1);
}
// Build an action map, which maps intent names to functions
let actionMap = new Map();
actionMap.set(QUESTION_1, reflect);
app.handleRequest(actionMap);
});
I want the 'reflect' function to be mapped to the GRATEFUL_2 response as well as GRATEFUL_1. I know how to do this, but how do I change this next bit to include both intents:
actionMap.set(QUESTION_1, reflect);
If you wanted the QUESTION_2 intent to also go to the reflect() function, you can simply add
actionMap.set(QUESTION_2, reflect);
But I don't think that is your problem. Inside reflect() you need to know which intent it was that got you there.
You can use app.getIntent() to get a string with the intent name and then match this to which response you want to give. So something like this might work:
function reflect( app ){
let intent = app.getIntent();
var grateful;
switch( intent ){
case QUESTION_1:
grateful = GRATEFUL_1;
break;
case QUESTION_2:
grateful = GRATEFUL_2;
break;
}
var response = app.getArgument( grateful );
app.tell( 'You previously said: '+response );
}
There are other variants, of course.
There is no requirement you actually use the actionMap and app.handleRequest() at all. If you have another way you want to determine which output you want to give based on the intent string, you're free to use it.
