okhttp中多个拦截器前一个拦截后，后面的拦截器是否不拦截

Question

我在使用okhttp3时设置拦截器时发现一个问题就是在当中设置多个拦截器

    //打印log的拦截器
    client.addInterceptor(LoggingInterceptor);
    //HTTP检查器
    client.addInterceptor(new ChuckInterceptor(application));
    //检查是否有网络
    client.addNetworkInterceptor(REWRITE_CACHE_CONTROL_INTERCEPTOR);
    //无网络读取本地缓存
    client.addInterceptor(REWRITE_CACHE_CONTROL_INTERCEPTOR);
    

我在第三个中打印log发现没有log打印出来，只有第一个拦截器中有log打印，所以我想问下是否时okhttp中的拦截器会当前拦截会导致之后的拦截器无法拦截

//判断是否需要读取缓存
private static final Interceptor REWRITE_CACHE_CONTROL_INTERCEPTOR = new Interceptor() {

    @Override
    public Response intercept(Interceptor.Chain chain) throws IOException {
        boolean netWorkConection = NetUtils.hasNetWorkConection(MyApplication.getIntstance());
        Request request = chain.request();
        if (!netWorkConection) {
            request = request.newBuilder()
                    .cacheControl(CacheControl.FORCE_CACHE)
                    .build();
        }

        Response response = chain.proceed(request);
        if (netWorkConection) {
            //有网的时候读接口上的@Headers里的配置，你可以在这里进行统一的设置
            String cacheControl = request.cacheControl().toString();
            response.newBuilder()
                    .removeHeader("Pragma")// 清除头信息，因为服务器如果不支持，会返回一些干扰信息，不清除下面无法生效
                    .header("Cache-Control", cacheControl)
                    .build();
        } else {
            int maxStale = 60 * 60 * 24 * 7;
            response.newBuilder()
                    .removeHeader("Pragma")
                    .header("Cache-Control", "public, only-if-cached, max-stale=" + maxStale)
                    .build();
        }
        KLog.i(TAG, "-----LoggingInterceptor----- :\nrequest url:" + request.url()  + "\nbody:" + response.body().string() + "\n");
        return response;
    }
};

//打印log的拦截器

private static final Interceptor LoggingInterceptor = new Interceptor() {
    @Override
    public Response intercept(Interceptor.Chain chain) throws IOException {
        Request request = chain.request();
        long t1 = System.nanoTime();
        okhttp3.Response response = chain.proceed(chain.request());
        long t2 = System.nanoTime();
        okhttp3.MediaType mediaType = response.body().contentType();
        String content = response.body().string();
        KLog.i(TAG, "-----LoggingInterceptor----- :\nrequest url:" + request.url() + "\ntime:" + (t2 - t1) / 1e6d + "\nbody:" + content + "\n");
        return response.newBuilder()
                .body(okhttp3.ResponseBody.create(mediaType, content))
                .build();
    }
};

response.body().string() 只能调用一次
