在实战中学AI-车流量统计项目-YOLOV11车辆检测-YOLOV11模型的部署考虑实际落地中部署推理资源消耗，速度与模型精度之间的均衡，同时，车辆属于比较通用场景的目标检测，我们将YOLOV11作为最终的模型选择，目前官方开源的模型基于coco数据集训练，里面已经包含了车辆相关类别，经测试，在监控视角下效果基本可用，所以，在落地过程中，我们先用这个模型来打通部署链路，后面再逐步优化模型性能。在Nvidia的硬件下做部署，部署框架优先选择官方框架TensorRT，下面重点讲述如何用TensorRT部署YOLOV11模型。阅读详情

20 CVPR Learning 3D Semantic Scene Graphs From 3D Indoor Reconstructions 学习笔记 3RScan是大规模真实世界的室内场景，特点是对478个自然改变的室内环境在不同的时间帧进行了1482 RGB-D scans，每一个scene都包括了一些位置被改变的物体。它和ScanNet数据集的区别主要在于ScanNet中的每一个采样环境都不相同，但是3RScan中存在采样环境相同但物体的位置不同的场景。Scene Graph Annotations 则是在3RScan的基础上给物体加入了场景图需要的关系、物体特征和类别标注，同时对3RScan进行了扩展，以此形成了场景图数据。阅读详情

			HttpHost proxy = new HttpHost(HsbcSmsUtilConfiguration.getPROXY_ADDRESS(), HsbcSmsUtilConfiguration.getPROXY_PORT());
			RequestConfig config = RequestConfig.custom().setProxy(proxy).build();

找了半天也没找到靠谱的地方，最后没办法去阿帕奇的官网找了找，找到个demo，已测试成功，希望能帮助后面的人。[/quote]忘了把地址挂上了 https://hc.apache.org/httpcomponents-client-ga/httpclient/examples/org/apache/http/examples/client/ClientProxyAuthentication.java

楼主能讲解一下么，我试了很多次，还是行不通。例如：我的代理是proxy.future.com,端口8080 用户：xiaoli，密码：000000 调用的请求： HttpGet httpGet = new HttpGet("http://www.ip138.com:8080/search.asp?mobile=13000467124&action=mobile"); 理论上设置这四个数就行了，为什么有多个认证范围，我怎么调用都报错：java.net.UnknownHostException: localhost.localdomain 如果楼主方便的话，请帮我写一下代码，先谢谢了。

/**

	 * @return
	 */
	public static CloseableHttpClient getHttpClient(String hostOrIP,int port,String userName,String password){
		//设置代理地址、代理端口号、协议类型
		HttpHost proxy = new HttpHost(hostOrIP,port,"http");
		DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxy);
		//创建认证，并设置认证范围
		CredentialsProvider credsProvider = new BasicCredentialsProvider();
		credsProvider.setCredentials(new AuthScope(hostOrIP,port),new UsernamePasswordCredentials(userName, password));
		
		HttpClientBuilder builder = HttpClients.custom();
		builder.setRoutePlanner(routePlanner);
		builder.setDefaultCredentialsProvider(credsProvider);
		CloseableHttpClient httpclient = builder.build();
//		CloseableHttpClient httpclient = builder.create().build();
		return httpclient;

你去网上找 4.3啊。

CloseableHttpClient httpclient = <...>

for (int i = 0; i < 3; i++) {
    CloseableHttpResponse response = httpclient.execute(

    try {
        HttpEntity entity = response.getEntity();

    } finally {
        response.close();
    }
}

具体你再看看。

十分感谢您的耐心解答，昨天就找到了，和您的这个是一样的，十分感谢

引用 3 楼 rui888 的回复:



client.getParams().setAuthenticationPreemptive(true);



Credentials defaultcreds = new UsernamePasswordCredentials("username", "password");

client.getState().setCredentials(new AuthScope("myhost", 80, AuthScope.ANY_REALM), defaultcreds);

参考

这个我i试过了，但是还是会报错，有一些类被弃用

System.getProperties().setProperty("proxySet", "true"); System.getProperties().setProperty("http.proxyHost", "xxxxxx"); System.getProperties().setProperty("http.proxyPort", "8080"); 这种不行吗

你帮我看下这个，public static String post(String url, Map<String, String> paramsMap) { { /* // yupian网地址 private static String URI = "yunpian.com"; //代理地址 private static String proxyAddress="10.0.0.122"; //代理地址的端口号 private static Integer proxyPort=1993;*/ // 创建HttpClientBuilder HttpClientBuilder httpClientBuilder = HttpClientBuilder.create(); CloseableHttpClient client =httpClientBuilder.build(); String responseText = ""; CloseableHttpResponse response = null; // 访问的目标站点，端口和协议 HttpHost targetHost = new HttpHost(URI, 443, "https"); System.out.println(targetHost); // 代理的设置 HttpHost proxy = new HttpHost(proxyAddress, proxyPort); RequestConfig config = RequestConfig.custom().setProxy(proxy).build(); try { HttpPost method = new HttpPost(url); method.setConfig(config); if (paramsMap != null) { List<NameValuePair> paramList = new ArrayList<NameValuePair>(); for (Map.Entry<String, String> param : paramsMap.entrySet()) { NameValuePair pair = new BasicNameValuePair(param.getKey(), param.getValue()); paramList.add(pair); } method.setEntity(new UrlEncodedFormEntity(paramList, ENCODING)); } response = client.execute(targetHost, method); HttpEntity entity = response.getEntity(); if (entity != null) { responseText = EntityUtils.toString(entity); } } catch (Exception e) { e.printStackTrace(); } finally { try { response.close(); } catch (Exception e) { e.printStackTrace(); } } // System.out.println(responseText); return responseText; } } 上面的这段代码用了代理，但是现在想让代理有用户名和密码，不知道在那里设置，找了好久了，不知道怎么去做
