电信天翼CtWing java对接上传设备、删除设备、下发指令

最近在做物联网的项目，正好对接电信aep的物联网开放平台，这里就跟大家分享一下我的遇到的问题和问题解决方式， 希望可以帮到大家

配置文件

我的后台用的springboot，所以直接在application.yml文件进行配置即可

jar包引入

需要导入两个jar包，可以在电信aep平台，找到下载地址

<dependency>
    <groupId>com.ctg.ag</groupId>
    <artifactId>ctg-ag-sdk-core</artifactId>
    <version>2.5.0-SNAPSHOT</version>
</dependency>

<dependency>
    <groupId>com.ctg.ag</groupId>
    <artifactId>ag-sdk-biz-84419.tar.gz</artifactId>
    <version>20220430.105806-SNAPSHOT</version>
</dependency>

工具类

@Component
public class CtWingUtil {
    //绑定配置文件中的参数，以后进行修改不用修改代码

    private static String APP_KEY;
    private static String APP_SECRET;

    @Value("${ctWing.APP_KEY}")
    public  void setAppKey(String appkey) {
        APP_KEY = appkey;
    }

    @Value("${ctWing.APP_SECRET}")
    public  void setAppSecret(String appSecret) {
        APP_SECRET = appSecret;
    }

    //增加设备 后面的参数是API文档中的请求参数
    public String createDevice(CreateDeviceDto dto, String masterKey){

        //创建一个客户端连接
        AepDeviceManagementClient client = AepDeviceManagementClient
                .newClient()
                .appKey(APP_KEY)
                .appSecret(APP_SECRET).build();

        CreateDeviceRequest request = new CreateDeviceRequest();
        request.setParamMasterKey(masterKey);

        //将对象转换为一个byte数组作为body传递
        byte[] body = JSON.toJSONBytes(dto);
        request.setBody(body);

        CreateDeviceResponse response=null; //为了方便在try外使用该参数

        //客户端调用方法
        try {
            response = client.CreateDevice(request);
        } catch (Exception e) {
            e.printStackTrace();
        }

        String string = new String(response.getBody());
        client.shutdown();  //关闭连接返回响应结果
        return string;
    }

    //增加设备 后面的参数是API文档中的请求参数
    public String deleteDevice(DelDeviceDto dto, String masterKey){

        //创建一个客户端连接
        AepDeviceManagementClient client = AepDeviceManagementClient
                .newClient()
                .appKey(APP_KEY)
                .appSecret(APP_SECRET).build();

        DeleteDeviceRequest request = new DeleteDeviceRequest();
        request.setParamMasterKey(masterKey);
        request.setParamDeviceIds(dto.getDeviceIds());
        request.setParamProductId(dto.getProductId());
        //将对象转换为一个byte数组作为body传递
//        byte[] body = JSON.toJSONBytes(dto);
//        request.setBody(body);

        DeleteDeviceResponse response=null; //为了方便在try外使用该参数

        //客户端调用方法
        try {
            response = client.DeleteDevice(request);
        } catch (Exception e) {
            e.printStackTrace();
        }

        String string = new String(response.getBody());
        client.shutdown();  //关闭连接返回响应结果
        return string;
    }

    //查询设备状态
    public int getDeviceStatus( String masterKey,String deviceId){
        //创建一个客户端连接
        AepDeviceManagementClient client = AepDeviceManagementClient
                .newClient()
                .appKey(APP_KEY)
                .appSecret(APP_SECRET).build();
        QueryDeviceRequest request=new QueryDeviceRequest();
        request.setParamMasterKey(masterKey);
        request.setParamDeviceId(deviceId);
        request.setParamProductId(xxxxx);

        QueryDeviceResponse response=null;
        try {
            response=client.QueryDevice(request);
        } catch (Exception e) {
            e.printStackTrace();
        }
        JSONObject body = JSONObject.parseObject(new String(response.getBody(), StandardCharsets.UTF_8));
        if(body.getJSONObject("result")!=null)
        {
            return  body.getJSONObject("result").getIntValue("netStatus");
        }
        client.shutdown();
        return 0;
    }

    //下发指令
    public JSONObject sendCommand(String requestStr,String masterKey) {
        //创建一个下发命令客户端
        AepDeviceCommandLwmProfileClient  client = AepDeviceCommandLwmProfileClient.newClient().appKey(APP_KEY).appSecret(APP_SECRET).build();
        //设备级命令
        CreateCommandLwm2mProfileRequest request = new CreateCommandLwm2mProfileRequest ();

    // 将请求体转换为JSON，再转化为Byte数组
     System.out.println(requestStr);
        JSONObject jsonObject = JSON.parseObject(requestStr);
        byte[] bytes = JSON.toJSONBytes(jsonObject);
        request.setBody(bytes);
        request.setParamMasterKey(masterKey);
        CreateCommandLwm2mProfileResponse response=null;
        try {
            response = client.CreateCommandLwm2mProfile(request);
        } catch (Exception e) {
            e.printStackTrace();
        }

        String resp= new String(response.getBody());
        System.out.println(resp);
        client.shutdown();  //关闭连接
        return JSONObject.parseObject(resp);
    }

遇到的问题

下发指令的格式 因为我这边使用的是LWM2M,在下发指令的时候，需要拼接好指令的格式，如下

/**
 * 下发指令
 */
@RequestMapping(value = "/sendCommd",method = RequestMethod.POST)
public Result sendCommd(@RequestBody Devices devices){
    Devices devices1=devicesService.getById(devices.getId());
    String json="{" +
            "  "deviceId": ""+devices1.getCode()+""," +
            "  "operator": "string"," +
            "  "productId": xxxx," +
            "  "ttl": 7200," +
            "  "level": 1," +
            "  "command":{" +
            " "serviceId":"DownCmdToDeviceLong","+
            " "method":"DownCmdLong","+
            " "paras": {"+
            "      "CmdId": "02"," +
            "      "TmpWidth": ""+devices.getTmpWidth()+""," +
            "      "TimePeriod": ""+devices.getTimePeriod()+""," +
            "      "MinCntSet": ""+devices.getMinCntSet()+""," +
            "      "Extend1": ""+devices.getExtend1()+""," +
            "      "Extend2": ""+devices.getExtend2()+""" +
            "    } }" +
            "}";
    ctWingUtil.sendCommand(json,"xxxxxxxxxxxxxxx");
    return Result.success();
}
