阿里云物联网获取设备属性api接口：QueryDevicePropertyData

阿里云物联网接口：QueryDevicePropertyData

说明：调用该接口查询指定设备或数字孪生节点，在指定时间段内，单个属性的数据

比如提取上传到物联网的温度数据

api文档：QueryDevicePropertyData_物联网平台_API文档-阿里云OpenAPI开发者门户QueryDevicePropertyData调用该接口查询指定设备或数字孪生节点，在指定时间段内，单个属性的数据。是物联网平台的API文档，是阿里云OpenAPI开发者门户提供的OpenAPI开发手册，包括云产品的OpenAPI、出入参、错误码、变更历史。https://next.api.aliyun.com/document/Iot/2018-01-20/QueryDevicePropertyData

搞了好久才搞出来：

1、java实现：

QueryDeviceTempData.java

java 复制代码

package com.example.iot;

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.iot.model.v20180120.QueryDevicePropertyDataRequest;
import com.aliyuncs.iot.model.v20180120.QueryDevicePropertyDataResponse;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;

public class QueryDeviceTempData {

    public static void main(String[] args) {
        // 阿里云访问密钥
        String accessKeyId = "**";
        String accessKeySecret = "**";
        String regionId = "cn-shanghai";

        // 设备信息
        String productKey = "**";
        String deviceName = "**";

        // 初始化客户端
        IClientProfile profile = DefaultProfile.getProfile(regionId, accessKeyId, accessKeySecret);
        IAcsClient client = new DefaultAcsClient(profile);

        // 创建请求
        QueryDevicePropertyDataRequest request = new QueryDevicePropertyDataRequest();
        request.setProductKey(productKey);
        request.setDeviceName(deviceName);
        request.setIdentifier("indate"); // 温度属性标识符
        request.setStartTime(System.currentTimeMillis() - 3600 * 1000); // 查询过去一小时的数据
        request.setEndTime(System.currentTimeMillis());
        request.setAsc(1); // 按时间升序排列
        request.setPageSize(10); // 每页返回的数据条数

        try {
            // 发送请求并获取响应
            QueryDevicePropertyDataResponse response = client.getAcsResponse(request);
            System.out.println("Response: " + response);

            // 解析响应
            if (response != null && response.getData() != null) {
                for (QueryDevicePropertyDataResponse.Data.PropertyInfo propertyInfo : response.getData().getList()) {
                    System.out.println("Time: " + propertyInfo.getTime() + ", Value: " + propertyInfo.getValue());
                }
            }
        } catch (ClientException e) {
            e.printStackTrace();
        }
    }
}

pom.xml文件：

java项目结构
java输出：

2、python实现

输出json格式，想要哪些字段自行解析

python 复制代码

from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkiot.request.v20180120.QueryDevicePropertyDataRequest import QueryDevicePropertyDataRequest

# 设置你的AccessKey ID和AccessKey Secret
access_key_id = '**'
access_key_secret = '**'
region_id = 'cn-shanghai'  # 根据你的实际情况选择region

# 创建AcsClient实例
client = AcsClient(access_key_id, access_key_secret, region_id)

# 创建QueryDevicePropertyDataRequest实例
request = QueryDevicePropertyDataRequest()
request.set_accept_format('json')

# 设置请求参数
request.set_ProductKey('**')  # 产品Key
request.set_DeviceName('**')  # 设备名称
request.set_Identifier('temp')  # 属性标识符
request.set_StartTime(1740346648574)  # 开始时间，Unix时间戳，单位毫秒
request.set_EndTime(1740357451888)  # 结束时间，Unix时间戳，单位毫秒
request.set_PageSize(10)  # 每页记录数
request.set_Asc(0)  # 0表示降序，1表示升序

try:
    # 发送请求并获取响应
    response = client.do_action_with_exception(request)
    print(response.decode('utf-8'))
except ClientException as e:
    print(e.get_error_code())
    print(e.get_error_msg())
except ServerException as e:
    print(e.get_error_code())
    print(e.get_error_msg())

python程序输出：{"RequestId":"036BBE41-52E9-5C5F-9312-D561C0D82282","Data":{"NextValid":false,"NextTime":1740355512752,"List":{"PropertyInfo":[{"Value":"-2.0","Time":1740357315548},{"Value":"-2.0","Time":1740357015021},{"Value":"-2.0","Time":1740356714858},{"Value":"-5.0","Time":1740356414687},{"Value":"-5.0","Time":1740356113089},{"Value":"-5.0","Time":1740355812915},{"Value":"-5.0","Time":1740355512754}]}},"Code":"","Success":true}
