BotMan Middleware to connect DialogFlow with BotMan

Thank's to @eclips16. The code source was taken from pull request.

Installation

Composer

composer require genkovich/dialog-flow-bot-man-middleware

Usage

.env

GOOGLE_CLOUD_PROJECT=project-id
GOOGLE_APPLICATION_CREDENTIALS=/path/to/security-file.json

Where can I get this variables?

Login at https://dialogflow.cloud.google.com/
Create NewAgent (or use an existing one)
Click on "Settings" icon (1)
Copy your project id (2) into .env file
Click on project id (2)

After that you will find "Service accounts" section (click (1) or (2))

Click on "Create service account", fill "name" field and click "Create"

On the next step you have to add two roles, "DialogFlow API Admin" and "DialogFlow API Client" and click "Done"

Now, go to the page "Manage keys"

Create new key in .json format

Move downloaded file into project root directory
Add path to file in .env

Code example

$dialogflow = \BotMan\Middleware\DialogFlow\V2\DialogFlow::create('en');
$botman->middleware->received($dialogflow);
$botman->hears('smalltalk.(.*)', function ($bot) {
    $extras = $bot->getMessage()->getExtras();
    $bot->reply($extras['apiReply']);
})->middleware($dialogflow);

smalltalk.(.*) - there is action name pattern

If you create actions with different prefixes, you can use ->ignoreIntentPattern()

$dialogflow = DialogFlow::create('en')->ignoreIntentPattern();
