It is my first time working with bots. I decided to use wit.ai bot, using PHP. What I am trying to do is to set callback function for the bot, for example when user ask for weather the bot will execute getWeather(). How can I pass this function to the bot if I am using cURL? Is it possible to do that? I found some SDKs on git but all of them are unofficial for wit.ai.
$ch = curl_init(); $headr = array(); $headr[] = "Authorization: Bearer XXXXXXXXXXXXXXXX"; curl_setopt($ch, CURLOPT_URL,"https://api.wit.ai/message?v=20170118&q=what is weather in London ?"); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_HTTPHEADER,$headr); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $server_output = curl_exec ($ch); curl_close ($ch); echo $server_output; i've found this SDK https://github.com/tgallice/wit-php, but i am not able to use ActionMapping its always given error :
Fatal error: Class 'ActionMapping' not found in /Users/jack/Documents/www/bar/index.php on line 12
my code :
<?php require_once __DIR__.'/vendor/autoload.php'; use Tgallice\Wit\Client; use Tgallice\Wit\ConverseApi; use Tgallice\Wit\Conversation; use Tgallice\Wit\Model\Step\Action; use Tgallice\Wit\Model\Step\Message; class MyActionMapping extends ActionMapping { /** * @inheritdoc */ public function action($sessionId, Context $context, Action $step) { return call_user_func_array(array($this, $step->getAction()), array($sessionId, $context)); } /** * @inheritdoc */ public function say($sessionId, Context $context, Message $step) { echo $step->getMessage(); } } $client = new Client('XXX'); $api = new ConverseApi($client); $actionMapping = new MyActionMapping(); $conversation = new Conversation($api, $actionMapping); $context = $conversation->converse('session_id', 'Hello I live in London'); 2 Answers

According to your error, are you sure about these things:
Install library:
First of all, install library via composer so that all files should add correctly. Maybe it will be the main cause.
Parameter passed in curl:
For wheater, you have used https://wit.ai/docs/http/20160526 API. Also here token part is missing form curl
and hit this function :
$ curl -XPOST 'https://api.wit.ai/converse?v=20160526&session_id=123abc&q=weather%20in%20Brussels' \ -H "Content-Type: application/json" \ -H "Accept: application/json" \ -H 'Authorization: Bearer $TOKEN' Response: { "type": "merge", "entities": {"location": [{"body": "Brussels", "value": {"type": "value", "value": "Brussels", "suggested": true}, "start": 11, "end": 19, "entity": "location"}]}, "confidence": 1 } Answers 2
The error clearly tells you the problem,
The ActionMapping that you are extending is not found, so you will need to import it:
add this use Tgallice\Wit\ActionMapping;
require_once __DIR__.'/vendor/autoload.php'; use Tgallice\Wit\Client; use Tgallice\Wit\ConverseApi; use Tgallice\Wit\Conversation; use Tgallice\Wit\ActionMapping; use Tgallice\Wit\Model\Step\Action; use Tgallice\Wit\Model\Step\Message; class MyActionMapping extends ActionMapping { /** * @inheritdoc */ public function action($sessionId, Context $context, Action $step) { return call_user_func_array(array($this, $step->getAction()), array($sessionId, $context)); } /** * @inheritdoc */ public function say($sessionId, Context $context, Message $step) { echo $step->getMessage(); } } $client = new Client('XXX'); $api = new ConverseApi($client); $actionMapping = new MyActionMapping(); $conversation = new Conversation($api, $actionMapping); $context = $conversation->converse('session_id', 'Hello I live in London'); By the way if you took some time to explore some examples you would notice that.
