Mijn Facebook-chat bot werkt, maar het is het terugsturen van meerdere berichten na mijn eerste bericht om het. Dit is mijn webhook script (ik waardeer het is een zeer ruwe werkend voorbeeld):
$challenge = $_REQUEST['hub_challenge'];
$verify_token = $_REQUEST['hub_verify_token'];
if ($verify_token === 'MY_VERIFICATION_TOKEN') {
echo $challenge;
}
$input = json_decode(file_get_contents('php://input'), true);
$sender = $input['entry'][0]['messaging'][0]['sender']['id'];
$message = $input['entry'][0]['messaging'][0]['message']['text'];
//API Url
$url = 'https://graph.facebook.com/v2.6/me/messages?access_token=<my-token>';
//Initiate cURL.
$ch = curl_init($url);
//The JSON data.
$jsonData = '{
recipient:{
id:'.$sender.'
},
message:{
text:Hey Lee!
}
}';
//Encode the array into JSON.
$jsonDataEncoded = $jsonData;
//Tell cURL that we want to send a POST request.
curl_setopt($ch, CURLOPT_POST, 1);
//Attach our encoded JSON string to the POST fields.
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded);
//Set the content type to application/json
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
//Execute the request
$result = curl_exec($ch);
