阿里云微服务消息队列MQTT管控API本地测试Quick Start

Step By Step

1、设备端建立连接进行消息收发
2、添加pom.xml依赖
3、集成测试

一、设备端建立连接进行消息收发参考官方Demo：MQ4IoTSendMessageToMQ4IoTUseSignatureMode完整正常的消息收发，确保设备在线。控制台快速查看

二、添加pom.xml依赖

 dependency 
 groupId com.aliyun /groupId 
 artifactId aliyun-java-sdk-core /artifactId 
 version 4.1.1 /version 
 /dependency 
 dependency 
 groupId com.aliyun /groupId 
 artifactId onsmqtt20200420 /artifactId 
 version 1.0.1 /version 
 /dependency

三、集成测试3.1 CodeSample

import com.aliyun.onsmqtt20200420.models.*;
import com.aliyun.teaopenapi.models.*;
import com.google.gson.Gson;
public class Sample {
 * 使用AK SK初始化账号Client
 * @param accessKeyId
 * @param accessKeySecret
 * @return Client
 * @throws Exception
 public static com.aliyun.onsmqtt20200420.Client createClient(String accessKeyId, String accessKeySecret) throws Exception {
 Config config = new Config()
 // 您的AccessKey ID
 .setAccessKeyId(accessKeyId)
 // 您的AccessKey Secret
 .setAccessKeySecret(accessKeySecret);
 // 访问的域名
// config.endpoint = "onsmqtt.cn-qingdao.aliyuncs.com";
 config.endpoint = "onsmqtt.cn-beijing.aliyuncs.com";
 return new com.aliyun.onsmqtt20200420.Client(config);
 public static void main(String[] args_) throws Exception {java.util.List String args = java.util.Arrays.asList(args_);
 com.aliyun.onsmqtt20200420.Client client = Sample.createClient(" access key ", " access secret 
 QuerySessionByClientIdRequest querySessionByClientIdRequest = new QuerySessionByClientIdRequest()
 .setClientId("GID_demo1@@@DEVICE_001")
 .setInstanceId("post-cn-st*********");
 // 复制代码运行请自行打印 API 的返回值
 QuerySessionByClientIdResponse response = client.querySessionByClientId(querySessionByClientIdRequest);
// System.out.println(response.body.onlineStatus);
 System.out.println(new Gson().toJson(response.body));
}

3.2 The Result

{"onlineStatus":true,"requestId":"87D17FA5-F1F9-48F3-893C-BD70C8CA3DED"}
