我想使用翻新从服务中获取数据，如何在android中实现呢？

Question

感谢http://www.jsonschema2pojo.org/

，我已经在自己的项目中创建了班级模型

下面的json是我必须从中获取数据的jsonArray。

{
  "response": true,
  "timestamp": "23-11-2018 01:21:13",
  "status": 200,
  "data_response": {
    "responseCapaDigital": {
      "responseDescription": "Operación exitosa",
      "responseID": 1
    },
    "encabezadoResp": {
      "tscNum": "0",
      "tscAlfa": "Operación exitosa",
      "fechaRsp": "2018-11-23T01:21:12.878"
    },
    "codeResponseFI": "0000",
    "descriptionResponseFI": "Bancos obtenidos correctamente",
    "totalBanks": "1",
    "bankList": [
      {
        "bankCode": "421",
        "bankName": "GEM-HSBC2",
        "bankShortName": "421"
      }
    ]
  },
  "description": "GET BANK CATALOG"
}

这应该工作的方式是当我发送一个BankCode例如“ 443”时，该服务将返回一个类似于上面的Json数组。

我的connectionHanlder包含：

@Headers({"Content-Type: application/json",
            "Authorization: Basic eE9IMC5JdlJaRFZaVTNkV05YazUwZHltVk9MTz"})
    @POST("catalog/getCatalogoBancos")
    Call<ResponseServiceModel> getCatalogoBancos(@Body String body);

我的RetrofitClient：

 public static final String BASE_URL = "http://my_ip:8484/v1/";

private static Retrofit retrofit = null;
final static OkHttpClient okHttpClient = new OkHttpClient.Builder()
        .readTimeout(120, TimeUnit.SECONDS)
        .connectTimeout(120, TimeUnit.SECONDS)
        .build();


public static Retrofit getApi() {
    if (retrofit == null) {
        GsonBuilder builder = new GsonBuilder();
        retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(ScalarsConverterFactory.create())
                .addConverterFactory(GsonConverterFactory.create(builder.create()))
                .client(getUnsafeOkHttpClient())
                .build();
    }
    return retrofit;
}

public static OkHttpClient getUnsafeOkHttpClient() {
    try {
        // Create a trust manager that does not validate certificate chains
        final TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
            @Override
            public void checkClientTrusted(
                    java.security.cert.X509Certificate[] chain,
                    String authType) throws CertificateException {
            }

            @Override
            public void checkServerTrusted(
                    java.security.cert.X509Certificate[] chain,
                    String authType) throws CertificateException {
            }

            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return new java.security.cert.X509Certificate[0];
            }
        }};

        // Install the all-trusting trust manager
        final SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(null, trustAllCerts,
                new java.security.SecureRandom());
        // Create an ssl socket factory with our all-trusting manager
        final SSLSocketFactory sslSocketFactory = sslContext
                .getSocketFactory();

        OkHttpClient okHttpClient = new OkHttpClient();
        okHttpClient = okHttpClient.newBuilder()
                .sslSocketFactory(sslSocketFactory)
                .readTimeout(120, TimeUnit.SECONDS)
                .connectTimeout(120, TimeUnit.SECONDS)
                .hostnameVerifier(org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER).build();

        return okHttpClient;
    } catch (Exception e) {
        throw new RuntimeException(e);
    }

}

最后是我在RequestMethods类中拥有的方法，在其中进行调用：

public void getBankNickName(final String bankId) {

    loadingDialog.show();
    JSONObject jsonCatalog = new JSONObject();
    try {
        jsonCatalog.put("bankId", bankId);
    } catch (JSONException e) {
        e.printStackTrace();
    }
    responseService = conectionHandler.getCatalogoBancos(jsonCatalog.toString());
    responseService.enqueue(new Callback<ResponseServiceModel>() {
        @Override
        public void onResponse(Call<ResponseServiceModel> call, Response<ResponseServiceModel> response) {
            Log.e("Catalog Code ", String.valueOf(response.code()));
            if (response.isSuccessful()) {
                ResponseServiceModel responseServiceModel = response.body();
                if (responseServiceModel.getResponse().equals(true)) {

                    Log.e("BankName",responseServiceModel.getDataResponse().getBankList().getBankName());

                    loadingDialog.dismiss();
                } else {
                    loadingDialog.dismiss();
                    responseError(response.body().getMessage());
                }
            } else {
                loadingDialog.dismiss();
                serverError();
            }
        }

        @Override
        public void onFailure(Call<ResponseServiceModel> call, Throwable t) {

        }
    });

}

当我在RequestMethods类中调用getBankNickName时，它将打印我的Log "Catalog code"但不打印Log"BankName"

我知道这是很多代码，但是我无法弄清楚！！！请帮助

您需要从mavenCentral()中添加gson-converter，以消耗JSON：

dependencies {
    api "com.squareup.retrofit2:retrofit:2.4.0"
    api "com.squareup.retrofit2:converter-gson:2.4.0"
}

然后使用jsonschema2pojo来创建所需的对象映射。
