Question

我正在学习如何在GSON中使用Retrofit库，这样我就可以让我的未来应用程序更加稳定。但是，我期待“奇怪的错误”。我从https://www.metaweather.com/api/location/search/?query=san获取位置（用于测试目的）

这是我的代码

MainActivity

public class MainActivity extends AppCompatActivity {

    private SOService mService;
    private long currentTime; //start time
    private long finishedTime; //end time


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mService = ApiUtils.getClient();

        currentTime = System.currentTimeMillis();
        mService.getLocations().enqueue(new Callback<List<LocationsList>>() {
            @Override
            public void onResponse(Call<List<LocationsList>> call, Response<List<LocationsList>> response) {
                if(response.isSuccessful()){
                    Log.d("TAG", response.body().toString());
                    finishedTime = System.currentTimeMillis();

                    Log.d("TAG", "It took " + TimeUnit.MILLISECONDS.toSeconds(finishedTime - currentTime) + " seconds to complete");

                }
                else{
                    Log.d("TAG","Code"+response.code());

                }
            }

            @Override
            public void onFailure(Call<List<LocationsList>> call, Throwable t) {
                Log.d("TAG",t.getMessage());
            }
        });


    }
}

ApiUtils

public class ApiUtils {

    private static final String BASE_URL="https://www.metaweather.com/";

    public static SOService getClient(){
     return RetrofitClient.getClient(BASE_URL).create(SOService.class);
    }
}

RetrofitClient

public class RetrofitClient {
    private static Retrofit client;

    public static Retrofit getClient(String baseUrl){
        if(client == null){
            client = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }
        return client;

    }
}

SOService

public interface SOService {
    @GET("/api/location/search/?query=san")
    Call<List<LocationsList>> getLocations();
}

我删除了包和导入以获得更干净的代码。 LocationList是POJO。执行代码时，我收到以下消息： 09-25 16：23：12.913 10994-10994 / pw.davor.www.retrofit D / TAG：[LocationsList {title ='San Francisco'....

09-25 16：23：12.913 10994-10994 / pw.davor.www.retrofit D / TAG：完成需要10秒钟

但是，当我在Postman中执行GET请求时，大约需要100-300ms。

改造和GSON - 需要10秒才能获取数据
