此错误又回来了！

我是Retrofit的初学者，我看过这篇文章：Retrofit: Expected BEGIN_OBJECT but was BEGIN_ARRAY

但即使我尝试将其改编为我的模型，我仍然无法使其工作。所以我的错误是：

Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 55 path $[0].genericDevice

我得到了什么：

[

    "deviceUuid": "btB4:99:4C:59:F8:1F",
    "genericDevice": {
      "manufacturerName": "BeeWi",

      "smartFunctions": [

        "rgbled",
        "whiteled"
      ]
    }
  },
  {

解析类'属性：

private String             deviceUuid;
private IoTGenericDevice   ioTGncDvc;

IoTGenericDevice子类'attributes：

public String                   manufacturerName;
public String                   productName;
public ArrayList<String>        smartFunctions = new ArrayList<String>();

改造电话：

@GET("/iot/scanning")
public void             getIoTs(@Header(Auth.ID_SESSION_HEADER) String idSession, Callback<IoT[]> cbk);

经理：

public void             getIoTs(final CallbackIoTs cbkIoTs)
    {
        AdapterUtils.createBboxService(bbox, IBboxIoTService.class).getIoTs
                (bbox.getSessionId(), new Callback<List<IoT>>()                                       //REST call
                {
                    @Override
                    public void success(List<IoT> iots, Response rsp)
                    {
                        int statCode = rsp.getStatus();

                        if (statCode == 200) {
                            List<IoT> iotLst = Arrays.asList(iots);
                            Log.e(LOG_TAG, iotLst.get(0).getIoTGncDvc().getMnf());
                            cbkIoTs.onResult(statCode, iotLst);
                        } else {
                            Log.e(LOG_TAG, "Unexpected response while getting IoTs. HTTP code: "
                                    + String.valueOf(statCode)
                                    + " - 200 expected");
                            cbkIoTs.onResult(statCode, null);
                        }
                    }

                        if (rtfErr.getResponse() != null)
                            statCode = rtfErr.getResponse().getStatus();

Answer 1

这应该是对象：

public class Test{

@Expose
private String deviceUuid;
@Expose
private GenericDevice genericDevice;
}

这是通用设备对象：

public class GenericDevice {

@Expose
private String manufacturerName;
@Expose
private String productName;
@Expose
private List<String> smartFunctions = new ArrayList<String>();
}

改装电话：

@GET("/iot/scanning")
public void             getIoTs(@Header(Auth.ID_SESSION_HEADER) String idSession, Callback<List<Test>> cbk);

适配器调用：

AdapterUtils.createBboxService(bbox, IBboxIoTService.class).getIoTs
                (bbox.getSessionId(), new Callback<List<Test>>(){...}

[Retrofit]：预计BEGIN_OBJECT但是BEGIN_ARRAY
