OkHttp3简单拦截器

先写一个类:用于okhttp中去实现

public class LoggingInterceptor implements Interceptor {
    @Override
    public Response intercept(Chain chain) throws IOException {
        //拿到Request对象
        Request request = chain.request();

        long t1 = System.nanoTime();
        System.out.println(" request  = " + String.format("Sending request %s on %s%n%s",
                request.url(), chain.connection(), request.headers()));

        //拿到Response对象
        Response response = chain.proceed(request);

        long t2 = System.nanoTime();
        //得出请求网络,到得到结果,中间消耗了多长时间
        System.out.println("response  " + String.format("Received response for %s in %.1fms%n%s",
                response.request().url(), (t2 - t1) / 1e6d, response.headers()));
        return response;
    }
}

然后去okhttp中去调用

LoggingInterceptor logging = new LoggingInterceptor();
client = new OkHttpClient.Builder()
        .addInterceptor(logging)
        .connectTimeout(5, TimeUnit.SECONDS)
        .writeTimeout(5, TimeUnit.SECONDS)
        .readTimeout(5, TimeUnit.SECONDS)
        .build();

即可
