Retrofit Android：如何获得 JSON 数据与 ZB9794896D699A6A78542122D3MVPC700

Question

伙计们，我对如何使用具有 MVP 架构的 retrofit 检索数据感到困惑，我已经尝试了其他步骤但对我不起作用，你能帮帮我吗？ 我仍在学习将 retrofit 与 MVP 架构一起使用

这是我的 JSON 数据：`

{
"status": 200,
  "success": true,
  "data": {
    "token": {
      "token_type": "Bearer",
      "expires_in": 1296000,

这是我的回应：

public class Connector implements Serializable {

@SerializedName("status")
@Expose
private String status;

@SerializedName("success")
@Expose
private String success;

@SerializedName("data")
@Expose
private List<Data> data;

public String getStatus() {
    return status;
}

public void setStatus(String status) {
    this.status = status;
}

public String getSuccess() {
    return success;
}

public void setSuccess(String success) {
    this.success = success;
}

public List<Data> getData() {
    return data;
}

public void setData(List<Data> data) {
    this.data = data;
}

@Override
public String toString() {
    return "Connector{" +
            "status='" + status + '\'' +
            ", success='" + success + '\'' +
            ", data=" + data +
            '}';
}

我的视图界面：

    public interface DataView {
    void onConnected(Connector response);
    void onErrorResponse(String errorResponse);
}

我的 PresenterImpl：

    public interface DataPresenterImpl {
    void connected(String status, String success, Connector connector);
}

我的主持人：

    public class DataPresenter implements DataPresenterImpl {

    DataView view;
    Context context;

    public DataPresenter(Context context, DataView view) {
        this.view = view;
        this.context = context;
    }

    @Override
    public void connected(String status, String success, Connector connector) {
        final Observable<Connector> connectorApi = NetworkClient.getNetworkClient(context)
                .getConnector().subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread());

        DisposableObserver<Connector> con =  connectorApi.subscribeWith(new DisposableObserver<Connector>() {
            @Override
            public void onNext(@NonNull Connector connector) {
                view.onConnected(connector);
            }

            @Override
            public void onError(@NonNull Throwable e) {
                view.onErrorResponse(e.getMessage());
            }

            @Override
            public void onComplete() {

            }
        });
    }
}

我的网络客户端：

public class NetworkClient extends Application {

    public static NetworkAPI getNetworkClient(Context context){
        Gson gson = new GsonBuilder().setPrettyPrinting().serializeNulls().setLenient().create();
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(BuildConfig.BASE_URL)
                .client(getClient())
                .addConverterFactory(GsonConverterFactory.create(gson))
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create()).build();

        return retrofit.create(NetworkAPI.class);
    }

    public static OkHttpClient getClient() {
        return new OkHttpClient.Builder()
                .connectTimeout(1, TimeUnit.MINUTES)
                .readTimeout(1, TimeUnit.MINUTES)
                .writeTimeout(1, TimeUnit.MINUTES)
                .addInterceptor(getLoggingInterceptor())
                .build();
    }


    public static HttpLoggingInterceptor.Level getInterceptorLevel(){
        if (BuildConfig.DEBUG)
            return HttpLoggingInterceptor.Level.BODY;
        else
            return HttpLoggingInterceptor.Level.NONE;
    }

    public static HttpLoggingInterceptor getLoggingInterceptor() {
        HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor();
        httpLoggingInterceptor.setLevel(getInterceptorLevel());
        return httpLoggingInterceptor;
    }
}

我的 API 接口：

public interface NetworkAPI {

    @FormUrlEncoded
    @POST("xxxx")
    Observable<LoginResponse> login(@Field("username") String username,
                                    @Field("password") String password,
                                    @Field("serial_number") String serial_number);

    @GET("xxx")
    Observable<Connector> getConnector();

}

Answer 1

问题：

您正在将关键data解析到列表中，但它是一个JSONObject包含子对象： token 、 user和team 。

@SerializedName("data")
@Expose
private List<Data> data;

此代码需要 JSONArray，但您的响应包含 JSONObject。

解决方案：

首先，为data键内的子对象为每个 object 创建 POJO 类。 在Data class 中为这些类声明变量以进行序列化。 最后，将上面的声明private List<Data> data改为private Data data ，
