This is an unofficial php sdk for Dialogflow and it's still in progress...
Dialogflow: Build brand-unique, natural language interactions for bots, applications and devices.
Via composer:
$ composer require iboldurev/dialogflow
Using the low level Client:
require_once __DIR__.'/vendor/autoload.php';
use DialogFlow\Client;
try {
$client = new Client('access_token');
$query = $client->get('query', [
'query' => 'Hello',
]);
$response = json_decode((string) $query->getBody(), true);
} catch (\Exception $error) {
echo $error->getMessage();
}Using the low level Query:
require_once __DIR__.'/vendor/autoload.php';
use DialogFlow\Client;
use DialogFlow\Model\Query;
use DialogFlow\Method\QueryApi;
try {
$client = new Client('access_token');
$queryApi = new QueryApi($client);
$meaning = $queryApi->extractMeaning('Hello', [
'sessionId' => '1234567890',
'lang' => 'en',
]);
$response = new Query($meaning);
} catch (\Exception $error) {
echo $error->getMessage();
}Using the low level asynchronous api:
require_once __DIR__.'/vendor/autoload.php';
use DialogFlow\Client;
use DialogFlow\Model\Query;
use DialogFlow\Method\QueryApi;
use GuzzleHttp\HandlerStack;
use React\EventLoop\Factory;
use WyriHaximus\React\GuzzlePsr7\HttpClientAdapter;
$loop = Factory::create();
$reactGuzzle = new \GuzzleHttp\Client([
'base_uri' => Client::API_BASE_URI . Client::DEFAULT_API_ENDPOINT,
'timeout' => Client::DEFAULT_TIMEOUT,
'connect_timeout' => Client::DEFAULT_TIMEOUT,
'handler' => HandlerStack::create(new HttpClientAdapter($loop))
]);
$client = new Client('bc0a6d712bba4b3c8063a9c7ff0fa4ea', new DialogFlow\HttpClient\GuzzleHttpClient($reactGuzzle));
$queryApi = new QueryApi($client);
$queryApi->extractMeaningAsync('Hello', [
'sessionId' => '123456789',
'lang' => 'en'
])->then(
function ($meaning) {
$response = new Query($meaning);
},
function ($error) {
echo $error;
}
);
$loop->run();The Dialog class provides an easy way to use the query api and execute automatically the chaining steps :
First, you need to create an ActionMapping class to customize the actions behavior.
namespace Custom;
class MyActionMapping extends ActionMapping
{
/**
* @inheritdoc
*/
public function action($sessionId, $action, $parameters, $contexts)
{
return call_user_func_array(array($this, $action), array($sessionId, $parameters, $contexts));
}
/**
* @inheritdoc
*/
public function speech($sessionId, $speech, $contexts)
{
echo $speech;
}
/**
* @inheritdoc
*/
public function error($sessionId, $error)
{
echo $error;
}
}And using it in the Dialog class.
require_once __DIR__.'/vendor/autoload.php';
use DialogFlow\Client;
use DialogFlow\Method\QueryApi;
use DialogFlow\Dialog;
use Custom\MyActionMapping;
try {
$client = new Client('access_token');
$queryApi = new QueryApi($client);
$actionMapping = new MyActionMapping();
$dialog = new Dialog($queryApi, $actionMapping);
// Start dialog ..
$dialog->create('1234567890', 'Привет', 'ru');
} catch (\Exception $error) {
echo $error->getMessage();
}
