PHP中的Fecebook Messenger Bot并不总是响应用户 [英] Fecebook Messenger Bot in PHP doesn't always respond to user

问题描述

  $ access_token =xxxxxxx; 
 $ 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] ['message'] [0] ['sender'] ['id']; 
 $ message = $ input ['entry'] [0] ['message'] [0] ['message'] ['text']; 
 
 $ url ='https://graph.facebook.com/v2.6/me/messages?access_token='.$access_token。'; 
 
 $ ch = curl_init（$ url）; 
 
 if（$ message ==嗨）
 {
 $ jsonData ='{
收件人：{
id： '$发件人''
}，
message：{
text：hello！ 
} 
}'; 
} 
 
 $ jsonDataEncoded = $ jsonData; 
 
 curl_setopt（$ ch，CURLOPT_POST，1）; 
 
 curl_setopt（$ ch，CURLOPT_POSTFIELDS，$ jsonDataEncoded）; 
 
 curl_setopt（$ ch，CURLOPT_HTTPHEADER，array（'Content-Type：application / json'））; 
 
 $ result = curl_exec（$ ch）; 
  

我的cron工作与开发人员指南相同

  curl -ik -X POSThttps://graph.facebook.com/v2.6/me/subscribed_apps?access_token=xxxxxx
  

所以基本上，除了连接和一个响应之外什么都没有。
当我个人发送嗨（作为页面所有者和应用程序所有者）时，我的机器人总是正确响应，但是当其他人尝试说Hi-bot有时候会有所回应，有时候不会（通常不是5个机器人）回覆一次）

此外，当我访问我的脚本网址时，它会给我错误：

 <$$${message：（＃100）参数收件人是必需的，type：OAuthException，code：100，fbtrace_id：DvrO1UEw5BJ} 
  

请帮助我设置正确。

解决方案

如果您忘记设置内容类型，也可能会发生这种情况。

I have relatively simple Facebook Messenger bot in php for research purposes:

$access_token = "xxxxxxx";
$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'];

$url = 'https://graph.facebook.com/v2.6/me/messages?access_token='.$access_token.';

$ch = curl_init($url);

if($message=="hi")
{
        $jsonData = '{
        "recipient":{
                "id":"'.$sender.'"
        },
    "message":{
            "text":"hello!"
    }
    }';
}

$jsonDataEncoded = $jsonData;

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded);

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));

$result = curl_exec($ch);

and my cron job is same as in developer guide

curl -ik -X POST "https://graph.facebook.com/v2.6/me/subscribed_apps?access_token=xxxxxx"

So basically, nothing besides connection and one response. When i personally send "hi" (as a page owner and app owner), my bot always responds correctly, but when other people try to say hi - bot sometimes responds, sometimes not (usually not, in 5 cases bot responded once)

Additionally, when i visit my script url, it gives me error:

{"error":{"message":"(#100) The parameter recipient is required","type":"OAuthException","code":100,"fbtrace_id":"DvrO1UEw5BJ"}}

Please help me to set this right.

解决方案

This might also happen if you forget to set the content-type as well.
