BotMan Dialogflow Driver

BotMan driver to handle Dialogflow fulfillment with BotMan.

Build Status codecov StyleCI

It uses eristemena/dialog-fulfillment-webhook-php library, so it supports v1 and v2 of Dialogflow request.

Installation & Setup

First you need to pull in the Driver.

composer require eristemena/botman-driver-dialogflow

If you're using BotMan Studio, that's pretty much it.

But if you don't, then load the driver before creating the BotMan instance:

DriverManager::loadDriver(\BotMan\Drivers\Dialogflow\DialogflowDriver::class);

// Create BotMan instance
BotManFactory::create([]);

Usage

Hearing Messages

You can start receiving message using hears() based on the Intent of the message,

$botman->hears('Intent Name', function ($botman) {
    // replies here
});

Single Message Reply

The simplest way to reply to an incoming message is using BotMan's own reply() method:

$botman->hears('Default Welcome Intent', function ($botman) {
    $botman->reply('Hi, welcome!');
});

Multiple Message Replies

Normally when you want to send multiple replies, you use reply() multiple times. Unfortunately this doesn't work for Dialogflow driver, cause the messages should be in a single response payload.

For that, you have to use specific methods for this driver addMessage() and sendMessage() as follow,

$botman->hears('Default Welcome Intent', function ($botman) {
    $botman->addMessage('Good morning');
    $botman->addMessage('How may i help you?');
    $botman->sendMessage();
});

Rich Messages

Use Dialogflow\RichMessage\Text

    $text = Text::create()
        ->text('Hello')
        ->ssml('
            <speak>
                Hello!
                <audio src="https://actions.google.com/sounds/v1/cartoon/clang_and_wobble.ogg"></audio>
            </speak>
        ')
    ;

    $botman->reply($text);

Use Dialogflow\RichMessage\Image

    $image = Image::create('https://picsum.photos/200/300');
    $botman
        ->addMessage('This is an image')
        ->addMessage($image)
        ->sendMessage()
    ;

Use Dialogflow\RichMessage\Card

    $card = Card::create()
        ->title('This is title')
        ->text('This is text body, you can put whatever here.')
        ->image('https://picsum.photos/200/300')
        ->button('This is a button', 'https://docs.dialogflow.com/')
    ;

    $botman
        ->addMessage('This is a card')
        ->addMessage($card)
        ->sendMessage()
    ;

Use Dialogflow\RichMessage\Suggestion

    $suggestion = Suggestion::create(['Tell me a joke', 'Tell me about yourself']);

    $botman
        ->addMessage('Hi, how can i help you with?')
        ->addMessage($suggestion)
        ->sendMessage()
    ;

Use Dialogflow\RichMessage\Payload

    $payload = Payload::create([
        'expectUserResponse' => false
    ]);

    $botman
        ->addMessage('Have a good day')
        ->addMessage($payload)
        ->sendMessage()
    ;
