OkHttp基本使用

异步Get请求

//第一步，创建OkHttpClient对象OkHttpClient client = new OkHttpClient();//第二步，创建request请求对象，以及把URL封装在里面Request request = new Request        .Builder()        .url(url)       .build();//第三步，进行异步请求client.newCall(request).enqueue(new Callback() {    @Override    public void onFailure(Call call, IOException e) {    }    @Override    public void onResponse(Call call, Response response) throws IOException {        mBody = response.body().string();    }});

同步Get请求

//同步请求只需在第三步只把enqueue改为execute，返回response对象 Response response = client.newCall(request).execute();
