如何从rabbitMQ向物联网集线器设备发送消息？

Question

I am trying to send message from rabbitMQ to IoT hub device named as dvc-test with php, i referred official documentation and tried the send.php code like below:

<?php
    require_once __DIR__ . '/vendor/autoload.php';
use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Message\AMQPMessage;

$host = '[MYHUBNAME].azure-devices.net';
$userName = 'XXXXXXXX'; //confused which iot hub crediential should comes device or iothub
$password = 'XXXXXXXX'; //confused which iot hub crediential should comes device or iothub
$connection = new AMQPStreamConnection($host, 5672, $userName, $password);
$channel = $connection->channel();

$channel->queue_declare('hello', false, false, false, false);
$json = '{"id":1, "value":"test"}';
$msg = new AMQPMessage($json);
$channel->basic_publish($msg, '', 'hello');

echo " [x] Sent ";

$channel->close();
$connection->close();

It worked for localhost with default given parameteres given in documentation, But if i tried with iot hub credientials it does not work for me.

please help

Answer 1

Please check rabbitmq logs if you see any connections from your ip. If there is nothing in log, then maybe some firewall is blocking amqp connection.

BTW, I assume that you are sending messages TO rabbimq, not from.

Answer 2

You can find an example here how to send messages with low level AMQP. For the authentication you need to generate a SAS token based on your device key.
