This is an unofficial php sdk for Wit.ai and it's still in progress...
Wit.ai: Easily create text or voice based bots that humans can chat with on their preferred messaging platform.
## Install:
Via composer:
$ composer require tgallice/wit-php
Using the low level Client:
require_once __DIR__.'/vendor/autoload.php';
use Tgallice\Wit\Client;
$client = new Client('app_token');
$response = $client->get('/message', [
'q' => 'Hello I live in London',
]);
// Get the decoded body
$intent = json_decode((string) $response->getBody(), true);You can used the Api class which provided some shortcut to call the wit api:
require_once __DIR__.'/vendor/autoload.php';
use Tgallice\Wit\Client;
use Tgallice\Wit\Api;
$client = new Client('app_token');
$api = new Api($client);
$intent = $api->getIntentByText('Hello I live in London');The Conversation class provides an easy way to use the converse api and execute automatically the chaining steps :
First, you need to create an ActionMapping class to customize the actions behavior.
namespace Custom;
class MyActionMapping extends ActionMapping
{
/**
* @inheritdoc
*/
public function action($sessionId, $actionName, Context $context)
{
return call_user_func_array(array($this, $actionName), array($sessionId, $context));
}
/**
* @inheritdoc
*/
public function say($sessionId, $message, Context $context)
{
echo $message;
}
....
}And using it in the Conversation class.
require_once __DIR__.'/vendor/autoload.php';
use Tgallice\Wit\Client;
use Tgallice\Wit\Api;
use Tgallice\Wit\Api\Conversation;
use Custom\MyActionMapping;
$client = new Client('app_token');
$api = new Api($client);
$actionMapping = new MyActionMapping();
$conversation = new Conversation($api, $actionMapping);
$context = $conversation->converse('session_id', 'Hello I live in London');Conversation::converse() return the last available Context.
Some examples are describe in the tgallice/php-wit-example repository.
- Create dedicated Api class for Intent
- Create dedicated Api class for Entity
