本文介绍了一个使用Retrofit结合OkHttp进行网络请求封装的实用案例。该案例通过单例模式创建Retrofit实例，并配置了OkHttp客户端实现网络请求的日志记录、超时设置及缓存管理等功能。

public class RetrofitUtils {
    private static RetrofitUtils retrofitUtils=null;
    private OkHttpClient okHttpClient;

    public static RetrofitUtils newInstance(){
        if(retrofitUtils==null){
            synchronized(RetrofitUtils.class){
                if(retrofitUtils==null){
                    retrofitUtils=new RetrofitUtils();
                }
            }
        }
        return retrofitUtils;
    }

    //构造方法 添加okhttpclient
    public RetrofitUtils(){
        //缓存目录
        File sdcache = new File(Environment.getExternalStorageDirectory(), "cache");
        int cacheSize = 10 * 1024 * 1024;
        //OkHttp3拦截器
        HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {
            @Override
            public void log(String message) {
                Log.i("xxx", message.toString());
            }
        });
        //Okhttp3的拦截器日志分类 4种
        httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);


        okHttpClient = new OkHttpClient.Builder().connectTimeout(15, TimeUnit.SECONDS)
                //添加OkHttp3的拦截器
                .addInterceptor(httpLoggingInterceptor)
                .writeTimeout(20, TimeUnit.SECONDS).readTimeout(20, TimeUnit.SECONDS)
                .cache(new Cache(sdcache.getAbsoluteFile(), cacheSize))
                .build();

    }
    //创建retrofitservice类
    public RetrofitService create(Class<RetrofitService> retrofitService, String baseurl){
        Retrofit retrofit = new Retrofit.Builder()
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .addConverterFactory(GsonConverterFactory.create())
                .baseUrl(baseurl)
                .client(okHttpClient)
                .build();
        RetrofitService service = retrofit.create(retrofitService);
        return service;
    }
