okhttp 封装 个笔记

1，到okhttp 找最新的版本：

implementation 'com.squareup.okhttp3:okhttp:3.10.0'

封装回调接口：

public abstract class OkhttpCallBack {
    public  abstract void FailureBack(Call request, Exception e);
    public  abstract void  SuccessBack(Response response) throws IOException;


}

OkHttp get 请求：

package com.example.administrator.okhttpencapsulation;


import android.content.Context;

import java.io.File;
import java.io.IOException;
import java.util.concurrent.TimeUnit;

import okhttp3.Cache;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public   class OkhttpMamager  {
   private  static  OkhttpMamager mInstance;
    private final OkHttpClient mokhttpClient;


    public  static OkhttpMamager getinstance(Context context){
         if (mInstance==null){
             synchronized (OkhttpMamager.class){
                 if (mInstance==null){

                     mInstance = new OkhttpMamager(context);
                 }

             }

         }
         return  mInstance;


     }
    public OkhttpMamager(Context context) {
        File sdcache=  context.getExternalCacheDir();
        int cache=10*1024*1024;
        OkHttpClient.Builder builer = new OkHttpClient.Builder().connectTimeout(15, TimeUnit.SECONDS)
                .readTimeout(20, TimeUnit.SECONDS)
                .writeTimeout(20, TimeUnit.SECONDS)
                .cache(new Cache(sdcache.getAbsoluteFile(), cache));
             mokhttpClient=builer.build();

    }


    public  void  getASynHttp(String url, final OkhttpCallBack callBack){
                        final Request request=new Request.Builder().url(url).build();
                  mokhttpClient.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                 callBack.FailureBack(call,e);
              }
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                 callBack.SuccessBack(response);
              }
        });



    }
