okhttp的使用

  okhttp使用之前必须导入

compile 'com.squareup.okhttp:okhttp:2.4.0'compile 'com.squareup.okio:okio:1.5.0'

public void getdata() {    //创建okHttpClient对象    OkHttpClient mOkHttpClient = new OkHttpClient();    //创建一个Request    final Request request = new Request.Builder()            .url(url)            .build();    //new call    Call call = mOkHttpClient.newCall(request);    call.enqueue(new Callback() {        @Override        public void onFailure(Request request, IOException e) {        }        @Override        public void onResponse(Response response) throws IOException {            final String res = response.body().string();                   然后开启主线程进行使用；                }            });        }    });}
