const iot = require('alibabacloud-iot-device-sdk');
const device = iot.device({

  	// "protocol": 'alis://', "protocol": 'wxs://'
});

device.subscribe('/b3QtGH1ubB2/test/user/get');  
device.on('connect', () => {
  console.log('connect successfully!');
  device.publish('/b3QtGH1ubB2/test/user/update','hello world!');
});
device.on('message', (topic, payload) => {
  console.log(topic, payload.toString());
});
