使用 json 获取查询 - Retrofit 2.0

Question

如何进行这个我将在下面提到的查询？

方法@GET。查询应如下所示：

/top40?data={"ranking":"world"} /top40?data={"ranking":"country"}

@GET("/api/top40")
    Call<FamousTop40Model> getStatus(
        // what should be there?
    );

    class Factory {
        private static FamousTop40Api service;

        public static FamousTop40Api getInstance() {
            Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl(ApiConstants.BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();

            service = retrofit.create(FamousTop40Api.class);

            return service;
        }
    }

你们能帮帮我吗？

编辑：+ 我应该在标题中有accessKey。

Answer 1

这对我有帮助：

public interface FamousTop40Api {
    @GET("/api/top40")
    Call<FamousTop40Model> getStatus(
            @Query("data") String ranking
    );

    class Factory {
        private static FamousTop40Api service;

        public static FamousTop40Api getInstance() {
            OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
            httpClient.addInterceptor(new Interceptor() {
                @Override
                public Response intercept(Interceptor.Chain chain) throws IOException {
                  Request original = chain.request();

                  Request request = original.newBuilder()
                          .header("accessKey", MainActivity.ACCESS_KEY)
                          .method(original.method(), original.body())
                          .build();

                  return chain.proceed(request);
                }
            });

            OkHttpClient client = httpClient.build();

            Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl(ApiConstants.BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(client)
                    .build();

            service = retrofit.create(FamousTop40Api.class);

            return service;
        }
    }
}

所以你需要在标题中添加@Query和accessKeyOkHttpClient

和

FamousTop40Api.Factory.getInstance().getStatus("{\"ranking\":\"country\"}").enqueue();

你可以这样调用你的 GET 方法：

public interface EndPointInterface{
@GET(ProximityConstants.URL_FETCH_STORE_INFO)
    Call<Store> getStoreInfoByBeaconUUID(@Query(ProximityConstants.BEACON_UUID) String beaconUUID);

}

要调用 GET 方法 webservice 像这样继续：

 Call<StoreSettings> call = apiService.getStoreSettings(mStore.getStoreID(), mCustomer.getCustId(),
                mStore.getBeaconID(), ProximityConstants.SETTINGS_CUST_TYPE, ProximityConstants.ACTION_STORE_VISIT);
        call.enqueue(new Callback<StoreSettings>() {
            @Override
            public void onResponse(Call<StoreSettings> call, Response<StoreSettings> response) {
                ProximityUtil.writeLog(TAG, "Received store settings");
                mStoreSettings = response.body();
                SharedPreferences.Editor editor = mAppPreferences.edit();
                editor.putString(ProximityConstants.SETTINGS_OBJ_STORE_SETTINGS, new Gson().toJson(mStoreSettings));
                editor.commit();
                Intent intent = new Intent(BeaconScanService.this, ProximityWelcomeActivity.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                BeaconScanService.this.startActivity(intent);
            }

            @Override
            public void onFailure(Call<StoreSettings> call, Throwable t) {
                Toast.makeText(BeaconScanService.this, "Error: " + t.getMessage(), Toast.LENGTH_LONG).show();
            }
        });

尝试如下：创建类Task.java：

public class Task {  
private String ranking;

public Task(String ranking) {
    this.ranking = ranking;
}
}

然后执行以下操作：

public interface TaskService {  

@POST("/top40?data=")
Call<Top40Model> getStatus(@Body Task task);

}

并使用如下：

Task task = new Task("world");  
Task task = new Task("country");  

Call<Top40Model> call=new Factory.getInstance().getStatus(task);
call.enqueue(new Callback<Top40Model>() {});
