MQTT 订阅问题

[crazyday7]

我是参考 https://github.com/bluerhinos/phpMQTT
执行范例接收MQTT没问题，但改用CodeIgniter去接收就不行
请问要怎么改才能运作?

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

include_once(__DIR__ . '/../third_party/phpMQTT.php');

class MQTT_subscribe extends CI_Controller {

	public function __construct()
	{
		parent::__construct();
	}

	public function MQTTSubscribe()
	{
		$server = "IP";     // change if necessary
		$port = 1883;                     // change if necessary
		$username = "XXX";                   // set your username
		$password = "XXX";                   // set your password
		$client_id = "phpMQTT-subscriber"; // make sure this is unique for connecting to sever - you could use uniqid()

		$mqtt = new phpMQTT($server, $port, $client_id);

		if(!$mqtt->connect(true, NULL, $username, $password)) {
			
			goto err_out;
		}

		$topics['bluerhinos/phpMQTT/examples/publishtest'] = array("qos" => 0, "function" => "procmsg");

		$mqtt->subscribe($topics, 0);

		while($mqtt->proc()){
				
		}
		
		$mqtt->close();

	err_out:
		return ;		
	}	
	
	function procmsg($topic, $msg){
		//echo "Msg Recieved: " . date("r") . "\n";
		//echo "Topic: {$topic}\n\n";
		//echo "\t$msg\n\n";

	err_out:
		return $msg;			
	}	
}

ci中的引入方式 不是这种吧 就想tp 有 vendor 函数一样 你引入后 实力化的时候 也是 $object = new \Model(); 这种方式 具体的你占一下错误信息把

有放log到phpMQTT.php，function有被呼叫 但function procmsg沒被呼叫 并没有提示错误
