okhttp LoggingInterceptor.java拦截器

首先创建一个类，

TokenInterceptor implements Interceptor 

public class TokenInterceptor implements Interceptor {
    @Override
    public Response intercept(Interceptor.Chain chain) throws IOException {
        //这个chain里面包含了request和response，所以你要什么都可以从这里拿
        Request request = chain.request();

        long t1 = System.nanoTime();//请求发起的时间


        Response response = chain.proceed(request);

        long t2 = System.nanoTime();//收到响应的时间

        //这里不能直接使用response.body().string()的方式输出日志
        //因为response.body().string()之后，response中的流会被关闭，程序会报错，我们需要创建出一
        //个新的response给应用层处理
        ResponseBody responseBody = response.peekBody(1024 * 1024);


        return response;
    }
}

之后在MainActivity类中，异步请求数据

final OkHttpClient client = new OkHttpClient.Builder().addNetworkInterceptor(new TokenInterceptor()).build();

        Request request = new Request.Builder().header("User-Agent", "OkHttp Example").url(url).build();
        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }

            @Override
            public void onResponse(Call call, final Response response) throws IOException {

      //请求成功
    runOnUiThread(new Runnable() {
    @Override
    public void run() {
        final String result;
        try{

            result = response.body().string();

            System.out.println("请求成功 = " + result+ "请求成功");

         /*   Gson gson = new Gson();
            Bean1 bean1 = gson.fromJson(result, Bean1.class);
            song_list = bean1.getSong_list();//集合

            mLayoutManager = new LinearLayoutManager(MainActivity.this,LinearLayoutManager.VERTICAL,false);
            rv.setLayoutManager(mLayoutManager);
            rv.setItemAnimator(new DefaultItemAnimator());

            myAdapter = new MyListAdapter(MainActivity.this,song_list);
            rv.setAdapter(myAdapter);

        */

         

        }catch (Exception e) {

        }
    }
});
            }
        });
