本文介绍了一个使用OkHttp 3.x版本进行网络请求的封装类NetUtils，支持GET和POST请求，并通过回调传递响应结果。文章展示了如何创建OkHttpClient实例，并提供doPost方法发送带参数的POST请求。

首先添加依赖:

compile 'com.squareup.okhttp3:okhttp:3.3.0'

public class NetUtils implements  Callback {
         private  static   NetUtils INSTANCE;
         private  final OkHttpClient   httpClient;
         private  HttpUtilsCallback mhttpUtilsCallback;
         public  NetUtils(){
             httpClient = new OkHttpClient.Builder().build();
                }
                //单例模式
          public  static  NetUtils  getInstance(){
             if (INSTANCE==null){
                 INSTANCE=new  NetUtils();
             }
             return  INSTANCE ;
          }
       /*         public String doGet(String path){
                    Request request = new Request.Builder().url(Constant.BASE_URL+ path).build();
                    Call call = httpClient.newCall(request);
                    call.enqueue(this);
                    return  "data ok";
    }*/
    public  void doPost(String path, HashMap<String,String> map, HttpUtilsCallback httpUtilsCallback){
               this.mhttpUtilsCallback=httpUtilsCallback;
        FormBody.Builder builder = new FormBody.Builder();
        Iterator<String> iterator = map.keySet().iterator();
        while (iterator.hasNext()){
            String key = iterator.next();
            String value = map.get(key);
            builder.add(key,value);
        }
        FormBody body = builder.build();
        Request request = new Request.Builder()
                .url(Constant.BASE_URL+path)
                .post(body)
                .build();
        Call call = httpClient.newCall(request);
        call.enqueue(this);
    }

    @Override
    public void onFailure(Call call, IOException e) {

    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
        String s = response.body().string();
        mhttpUtilsCallback.onSuccess(s);
        //Log.e("--------","data"+string);
    }
}
