【问题描述】:
我想根据这个脚本编写Messenger bot:
<?php
$challenge = $_REQUEST['hub_challenge'];
$verify_token = $_REQUEST['hub_verify_token'];
// Set this Verify Token Value on your Facebook App
if ($verify_token === 'testtoken') {
echo $challenge;
}
$input = json_decode(file_get_contents('php://input'), true);
// Get the Senders Graph ID
$sender = $input['entry'][0]['messaging'][0]['sender']['id'];
// Get the returned message
$message = $input['entry'][0]['messaging'][0]['message']['text'];
//API Url and Access Token, generate this token value on your Facebook App Page
$url = 'https://graph.facebook.com/v2.6/me/messages?access_token=<ACCESS-TOKEN-VALUE>';
//Initiate cURL.
$ch = curl_init($url);
//The JSON data.
$jsonData = '{
"recipient":{
"id":"' . $sender . '"
},
"message":{
"text":"The message you want to return"
}
}';
//Tell cURL that we want to send a POST request.
curl_setopt($ch, CURLOPT_POST, 1);
//Attach our encoded JSON string to the POST fields.
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
//Set the content type to application/json
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
//Execute the request but first check if the message is not empty.
if(!empty($input['entry'][0]['messaging'][0]['message'])){
$result = curl_exec($ch);
}
?>
一切正常,但我收到两个对变量 $message 的响应,例如:
- 发送“你好”;
- $message = "你好";
- 接收消息:“嗨”;
- $message = "你好";
我想跳过 3 分和 4 分,只收到“Hello”消息,因为我必须检查 $message 是否是我的问题或答案。可能吗? 问候
