本文介绍了一个使用Retrofit实现的网络请求辅助类的设计与实现细节。该辅助类封装了Retrofit实例的创建过程，并提供了获取不同API接口的方法。通过单例模式确保了OkHttpClient和Retrofit实例的唯一性，同时利用了懒加载来优化资源使用。

public class RetrofitHelper {

    private static volatile OkHttpClient okHttpClient;
    private static volatile Retrofit retrofit;

    static {
        initHttp();
    }

    private static void initHttp() {
        if (okHttpClient == null) {
            synchronized (RetrofitHelper.class) {
                if (okHttpClient == null) {
                    HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
                    logging.setLevel(HttpLoggingInterceptor.Level.BODY);

                            .addInterceptor(new GetParamsInterceptor())
                            .addInterceptor(logging)

    private static <T> T createApi(Class<T> clazz){
        return getRetrofit().create(clazz);
