在改造Android的YouTube数据API

问题描述

我用我的Andr​​oid应用程序YouTube数据API V3。我还使用了改造提出请求的API。我能够与服务器，但我得到的响应进行沟通是不是能解析它。

I am using Youtube data API V3 in my android application. I am also using Retrofit for making requests to the API. I am able to communicate with the server but the response I am getting is not able to parse it.

public interface APIService {

    //////////////////////// Auth ///////////////////
    @GET("/youtube/v3/search")
    Call<JSONObject> getYoutbeFeeds(@Query("key") String developerKey, @Query("channelId") String channelId,@Query("part") String id,@Query("alt") String alt);
    /////////////////////////////////////////////
}

从那里我打电话的Youtube API片段

Fragment from where I am calling Youtube API

public class YoutubeFeedsFragment extends BaseFragment{

private APIService apiService = APIClient.getAPIService(Constants.YOUTUBE_FEEDS_URL);;


@Override
public void onStart() {
    super.onStart();
    Call<JSONObject> callBack = apiService.getYoutbeFeeds(Constants.DEVELOPER_KEY,Constants.CHANNEL_ID,"id","json");
    Log.i("data", "service called");
    Log.i("data", callBack.toString());
    callBack.enqueue(new retrofit.Callback<JSONObject>() {
        @Override
        public void onResponse(Response<JSONObject> response) {
            if(response.body() != null) {
                Log.i("data", "not null");

            }
            Log.i("data",response.data());

        @Override
        public void onFailure(Throwable t) {
            Toast.makeText(getActivity(),"sorry connection problem",Toast.LENGTH_LONG).show();
            }
        });
    }
}

常量类

public class Constants {
    public static final String CHANNEL_ID = "XXXXXXXXXXXXXXXXX";
    public static final String DEVELOPER_KEY = "AAAAAAAAAAAAAAAAAAAAA";

    public static String YOUTUBE_FEEDS_URL = "https://www.googleapis.com";
}

API客户端构建网址

API Client building the URL

public class APIClient {
    public static APIService getAPIService(String baseUrl) {

    OkHttpClient client = new OkHttpClient();
    client.interceptors().add(new LoggingInterceptor());

    if (apiService == null) {
        Retrofit restAdapter = new Retrofit.Builder()
                .baseUrl(baseUrl)
                .addConverterFactory(GsonConverterFactory.create())
                .client(client)
                .build();

        apiService = restAdapter.create(APIService.class);
    }
    return apiService;
}

我得到的响应为空。当我提出从邮差GET请求（REST API）我得到的JSON。请告诉我如何解析Android中使用的改装YouTube数据API响应。

I am getting response as null. When I am making the GET request from the Postman(REST API) I am getting the JSON. Please tell me how to parse the Youtube Data API response in Android using retrofit.

由于提前

推荐答案

您使用 .addConverterFactory（GsonConverterFactory.create（））这将不返回的JSONObject ，但已经被解析JSON（通过GSON转换器）。
例如，如果你的JSON必须返回是这样的：

You used .addConverterFactory(GsonConverterFactory.create()) which won't return a JSONObject but an already parsed json (via the Gson converter).For example if your json must return something like:

{
  result: "searchResult"
}

然后，您将创建一个类结果是这样的：

public class Result {

  @SerializedName("result")
  private String result;

  public String getResult(){
    return result;
  }

  public void setResult(String result) {
    this.result = result;
  }
}

和您的 ApiService 将这个样子的：

public interface APIService {

    //////////////////////// Auth ///////////////////
    @GET("/youtube/v3/search")
    Call<Result> getYoutbeFeeds(@Query("key") String developerKey, @Query("channelId") String channelId,@Query("part") String id,@Query("alt") String alt);
    /////////////////////////////////////////////
}
