## Overview

The current SDK is to facilitate developers to connect to Tuya’s message center and access pulsar.

For more information, see Tuya [Message Queue](https://developer.tuya.com/en/docs/iot/open-api/message-service/message-service?id=K95zu0nzdw9cd).

## Preparation before use

* ACCESS_ID: Obtained from Tuya platform

* ACCESS_KEY: Obtained from Tuya platform

* Pulsar address: Choose Pulsar address according to different business areas. For more information about acquiring the address, see Tuya [Message Queue](https://developer.tuya.com/en/docs/iot/open-api/message-service/message-service?id=K95zu0nzdw9cd).

## Example

```

public class ConsumerExample {

    private static final Logger logger = LoggerFactory.getLogger(ConsumerExample.class);

    private static String URL = MqConfigs.CN_SERVER_URL;

    private static String ACCESS_ID = "";

    private static String ACCESS_KEY = "";

    public static void main(String[] args) throws Exception {

        MqConsumer mqConsumer = MqConsumer.build().serviceUrl(URL).accessId(ACCESS_ID).accessKey(ACCESS_KEY)

                .messageListener(message -> {

                    System.out.println("---------------------------------------------------");

                    System.out.println("Message received:" + new String(message.getData()) + ",time="

                            + message.getPublishTime() + ",consumed time=" + System.currentTimeMillis());

                    String payload = new String(message.getData());

                    payloadHandler(payload);

                });

        mqConsumer.start();

    }

    /**

     * This method is used to process your message business

     */

    private static void payloadHandler(String payload) {

        try {

            MessageVO messageVO = JSON.parseObject(payload, MessageVO.class);

            //decryption data

            String dataJsonStr = AESBase64Utils.decrypt(messageVO.getData(), ACCESS_KEY.substring(8, 24));

            System.out.println("messageVO=" + messageVO.toString() + "\n" + "data after decryption dataJsonStr=" + dataJsonStr);

        } catch (Exception e) {

            logger.error("payload=" + payload + "; your business processing exception, please check and handle. e=", e);

        }

    }

}
