This library is a helper for google actions with php.

Install via composer

Require the package with composer:

composer require maxbeckers/google-actions-php

Usage

Handle the request:

• map request data to request object
• validate request
• handle request data
• create response
• send response

Map request data to request object

Map needed request headers and request body to Request.

use MaxBeckers\GoogleActions\Request\Request;
...
$requestBody  = file_get_contents('php://input');
$googleRequest = Request::fromGoogleRequest($requestBody);

Validate request

The RequestValidator will handle the google request validation.

use MaxBeckers\GoogleActions\Validation\RequestValidator;
...
$validator = new RequestValidator();
$validator->validate($googleRequest);

Register request handlers

For different requests it's helpful to create different RequestHandlers.

use MaxBeckers\GoogleActions\RequestHandler\RequestHandlerRegistry;
...
$requestHandlerRegistry = new RequestHandlerRegistry();
$requestHandlerRegistry->addHandler($myRequestHandler);

Use registry to handle request

use MaxBeckers\GoogleActions\RequestHandler\RequestHandlerRegistry;
...
$requestHandler = $requestHandlerRegistry->getSupportingHandler($googleRequest);
$response       = $requestHandler->handleRequest($googleRequest);

Render response

header('Content-Type: application/json');
echo json_encode($response);
exit();

Create a new request handler

The new request handler must extend AbstractRequestHandler. First implement the abstract supportsRequest-method.

public function supportsRequest(Request $request): bool
{
    return true; // check request data
}

Then implement the handleRequest-method. For simple responses there is a ResponseHelper.

use MaxBeckers\GoogleActions\Helper\ResponseHelper;
...
/** @var ResponseHelper */
private $responseHelper;
...
public function handleRequest(Request $request): Response
{
    // todo set needed response data
    return $responseHelper->respond('Success :)');
}
