AWS：获取所有 IoT 事物 ->Java 获取 aws-iot 所有事物

python 版本的可以参考：https://blog.csdn.net/qq_33811662/article/details/80732275

首先需要一个 ListThings 权限 AWS 的 IAM 帐号，需要获取 access_key 与 secret_key。

需要引用一个 iot 包，此处我是使用 Maven 构建的项目，在 pom.xml 中加入

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-iot</artifactId>
    <version>1.11.347</version>
</dependency>

接下去就是代码部分：

import java.util.List;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.regions.Region;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.iot.AWSIot;
import com.amazonaws.services.iot.AWSIotClient;
import com.amazonaws.services.iot.model.ListThingsRequest;
import com.amazonaws.services.iot.model.ListThingsResult;
import com.amazonaws.services.iot.model.ThingAttribute;

public class IoTTest {
    static AWSIot iot;
    private static String AWS_ACCESS_KEY = "xxxxxxxx"; // 你的 access_key
    private static String AWS_SECRET_KEY = "xxxxxxxx"; // 你的 secret_key

    static {
        iot = new AWSIotClient();
        iot.setRegion(Region.getRegion(Regions.US_EAST_1)); // 根据自己的地区调整
    }

    public static void main(String[] args) {
        AWSCredentials credentials = new AWSCredentials() {
            @Override
            public String getAWSSecretKey() {
                return AWS_SECRET_KEY;
            }

            @Override
            public String getAWSAccessKeyId() {
                return AWS_ACCESS_KEY;
            }
        };
        ListThingsRequest listThingsRequest = new ListThingsRequest();
        listThingsRequest.setRequestCredentials(credentials);
        ListThingsResult listThingsResult = iot.listThings(listThingsRequest);
        List<ThingAttribute> list = listThingsResult.getThings();
        list.forEach(e -> System.out.println(e.getThingName()));
    }

}
