关于mqtt:php调用阿里云mqtt

依赖

composer require php-mqtt/client v1.1.0

应用

$mqtt - new MqttService([
  'acessKeyID' => 'XXXX',// 账号的 AccessKey，在阿里云控制台查看
  'accessKeySecret' => 'XXXX', // 账号的的 SecretKey，在阿里云控制台查看
  'endpoint' => 'XXXX.mqtt.aliyuncs.com',// 设置以后用户的接入点域名，接入点获取办法请参考接入筹备章节文档，先在控制台创立实例
  'instanceId' => 'XXXX', // 实例 ID，购买后从控制台获取
  'groupId' => 'GID_XXXX',//MQTT GroupID, 创立实例后从 MQTT 控制台创立
  'topic'=>'XXXX', // 须要操作的 Topic, 第一级父级 topic 须要在控制台申请
  'deviceId' => 'XXXX',// 客户端惟一示意
])
# 获取客户端参数
$mqtt->getClientInfo($deviceId)
# p2p 发送音讯
$mqtt->p2pPublish(deviceId, '我是测试');
# 自定义发送音讯内容 $clientId 生成规定：$topic + $groupId + '@@@' + $deviceId 例如:'topic/p2p/GID_XXXX@@@00001'
$mqtt->publish($clientId, '我是测试');
