今天在公司使用httpClient时候.发生了如下错误：

经过查阅资料才发现,由于在公司使用的是代理地址

![这里写图片描述][Image 1]

只能使用HttpClient 代理模式访问 http/https请求  
代码如下  
String data = HttpClientUtil.proxyHttpGetRequest(url, “10.0.60.80”, 8080);

public static  String proxyHttpGetRequest(String url,String host,int port) throws IOException {
      //代理对象
      HttpHost proxy = new HttpHost(host,port,"http");
            RequestConfig requestConfig =     RequestConfig.custom().setProxy(proxy).build();
            //实例化CloseableHttpClient对象
            CloseableHttpClient httpclient = HttpClients.custom().setDefaultRequestConfig(requestConfig).build();
            //访问目标地址
            HttpGet httpGet = new HttpGet(url);
            //请求返回
            CloseableHttpResponse httpResp = httpclient.execute(httpGet);
            return EntityUtils.toString(httpResp.getEntity());
        }
