interface中:

package shopping.bwie.com.baiduditu.intfacex;

import retrofit2.http.GET;
import retrofit2.http.Query;
import rx.Observable;


public interface Retrofit_Intreface {
    @GET("news.php?type=top&tdsourcetag=s_pcqq_aiomsg")
    Observable getUrl(@Query("page") int page);
}

拦截器

package shopping.bwie.com.baiduditu.model;

import java.io.IOException;

import okhttp3.Interceptor;
import okhttp3.Request;
import okhttp3.Response;

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;
    }
}
