HttpClient4.5.3设置代理（Proxy）访问目标地址

数据采集，爬虫等可能需要用到代理IP来访问目标地址，以下代码为HttpClient4.5.3使用代理（Proxy）访问目标地址

        //设置代理IP、端口、协议（请分别替换）        HttpHost proxy = new HttpHost("你的代理的IP", 8080, "http");        //把代理设置到请求配置        RequestConfig defaultRequestConfig = RequestConfig.custom()                .setProxy(proxy)                .build();        //实例化CloseableHttpClient对象        CloseableHttpClient httpclient = HttpClients.custom().setDefaultRequestConfig(defaultRequestConfig).build();        //访问目标地址        HttpGet httpGet = new HttpGet("http://www.baidu.com");        //请求返回        CloseableHttpResponse httpResp = httpclient.execute(httpGet);        try {            int statusCode = httpResp.getStatusLine().getStatusCode();            if (statusCode == HttpStatus.SC_OK) {                System.out.println("成功");            }        } catch (Exception e) {        } finally {            httpResp.close();        }
