博客介绍了如何在OkHttp中定义常量和初始化对象，包括创建Request、Response、Call对象，设置OkHttpClient的超时时间，并定义了不同类型的MediaType常量以及网络请求的标记TAG。

   //创建队列，用于异步调用
    private Request request;

    //线程阻塞方式调用
    private Response response;

    //访问对象
    private Call call;

    //okhttp实例
    private OkHttpClient mOkHttpClient;

    //线程阻塞方式请求的get，post状态码
    private final static int GET_INSTANCE = 0;
    private final static int POST_INSTANCE = 1;

    //默认超时时间
    private final static int VALUE_DEFAULT_TIME_OUT = 20 * 1000;

    /**
     * 参数类型
     * "text", 文本
     * "image", 图片
     * "audio",音频
     * "video"，视频
     * "object",其他
     */
    private static final MediaType MEDIA_TYPE_TEXT = MediaType.parse("text/x-markdown; charset=utf-8");
    private static final MediaType MEDIA_TYPE_JPG = MediaType.parse("image/png");
    private static final MediaType MEDIA_TYPE_AUDIO = MediaType.parse("audio/mp3");
    private static final MediaType MEDIA_TYPE_VIDEO = MediaType.parse("video/mp4");
    private static final MediaType MEDIA_TYPE_OBJECT = MediaType.parse("application/octet-stream");
    private static final MediaType MEDIA_TYPE_JSON = MediaType.parse("application/json; charset=utf-8");

//给每个网络请求的标记
    public static final String TAG_DATA = "tag_data";
    public static final String TAG_IMAGE = "tag_image";
    public static final String TAG_FILE = "tag_file";

private RequestHandle() {
        //创建okHttpClient对象
        mOkHttpClient = new OkHttpClient();
        mOkHttpClient.setConnectTimeout(VALUE_DEFAULT_TIME_OUT, TimeUnit.MILLISECONDS);//连接超时
        mOkHttpClient.setReadTimeout(VALUE_DEFAULT_TIME_OUT, TimeUnit.MILLISECONDS);//读取超时
        mOkHttpClient.setWriteTimeout(VALUE_DEFAULT_TIME_OUT, TimeUnit.MILLISECONDS);//写入超时
    }
