我想建立一個非常簡單的機器人。我生成了一個訪問令牌,在我的Web服務器(SSL認證)上創建了一個簡單的index.php
文件,設置了一個webhook,指向我的index.php
文件,訂閱了我的webhook到我的頁面事件(developers.facebook.com上的所有內容)機器人並沒有得到答案。可能是什麼問題?信使機器人不工作
(我已經檢查一切:兩個標記,我管理等)
這裏是我的代碼:
<?php
$access_token = "i-filled-this-out";
$verify_token = "i-also-filled-this-out";
$hub_verify_token = null;
if(isset($_REQUEST['hub_challenge'])) {
$challenge = $_REQUEST['hub_challenge'];
$hub_verify_token = $_REQUEST['hub_verify_token'];
}
if ($hub_verify_token === $verify_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'];
$message_to_reply = '';
$message_to_reply = 'Huh! what do you mean?';
//API Url
$url = 'https://graph.facebook.com/v2.6/me/messages?access_token='.$access_token;
//Initiate cURL.
$ch = curl_init($url);
//The JSON data.
$jsonData = '{
"recipient":{
"id":"'.$sender.'"
},
"message":{
"text":"'.$message_to_reply.'"
}
}';
//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'));
//curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
//Execute the request
if(!empty($input['entry'][0]['messaging'][0]['message'])){
$result = curl_exec($ch);
}
