import retrofit2.converter.gson.GsonConverterFactory;

public class RetrofitApi {

                .baseUrl(UrlUtil.BASE_URL)//baseurl必須以/結尾
                .addConverterFactory(GsonConverterFactory.create())//添加數據解析器，即序列化器
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .client(OkHttpUtil.okHttpClient)//指定http客戶端
