下载tokudu-PhpMQTTClient-ba4e494.zip

下载rsmb_1.2.0.zip（windows环境下要开\windows\broker.exe 切记切记）

解压tokudu-PhpMQTTClient-ba4e494.zip

www下边新建目录androidpush

把解压文件tokudu-PhpMQTTClient-ba4e494中的SAM文件夹copy到androidpush目录下

把解压文件tokudu-PhpMQTTClient-ba4e494中的send_mqtt.php文件copy到androidpush目录下

结构如图：

send_mqtt.php主文件

[php] view plaincopyprint?
  1. <?php
  3. require('SAM/php_sam.php');
  5. //create a new connection object
  6. //创建一个新的连接对象
  7. $conn =new SAMConnection();
  9. //start initialise the connection
  10. //开始初始化连接 SAM_HOST服务器host路径 ；SAM_PORT服务器port端口号
  11. $conn->connect(SAM_MQTT,array(SAM_HOST =>'127.0.0.1',
  12. SAM_PORT => 1883));
  13. //create a new MQTT message with the output of the shell command as the body
  14. //建立一个新的MQTT shell命令的输出消息以作为主体（$msgCpu是通知内容）
  15. //new SAMMessage() 参数一般写为json格式
  16. $msgCpu =new SAMMessage("测试通知");
  18. //send the message on the topic cpu
  19. //发送该信息的主体
  20. //860173018344139是设备号，每一台android手机对应一个唯一的设备号
  21. //$msgCpu通知内容
  22. //send()推送通知
  23. $conn->send('topic://'.'860173018344139',$msgCpu);
  25. //关闭连接
  26. $conn->disconnect();
  28. echo 'MQTT Message to ' .'860173018344139' .' sent: ' .'测试通知';
