java代理ip有效检测

java实现代理ip有效检测，依赖Apache的HttpClient 正式版：

      /**       * 批量代理IP有效检测       *       * @param proxyIpMap       * @param reqUrl       */      public static void checkProxyIp(Map<String, Integer> proxyIpMap, String reqUrl) {             for (String proxyHost : proxyIpMap.keySet()) {                  Integer proxyPort = proxyIpMap.get(proxyHost);                   int statusCode = 0;                  try {                        HttpClient httpClient = new HttpClient();                        httpClient.getHostConfiguration().setProxy(proxyHost, proxyPort);                         // 连接超时时间（默认10秒 10000ms） 单位毫秒（ms）                        int connectionTimeout = 10000;                        // 读取数据超时时间（默认30秒 30000ms） 单位毫秒（ms）                        int soTimeout = 30000;                        httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(connectionTimeout);                        httpClient.getHttpConnectionManager().getParams().setSoTimeout(soTimeout);                         HttpMethod method = new GetMethod(reqUrl);                         statusCode = httpClient.executeMethod(method);                  } catch (Exception e) {                        // TODO Auto-generated catch block                        e.printStackTrace();                  }                  System.out.format(“%s:%s–>%s\n”, proxyHost, proxyPort, statusCode);            }      }       /**       * 代理IP有效检测       *       * @param proxyIp       * @param proxyPort       * @param reqUrl       */      public static void checkProxyIp(String proxyIp, int proxyPort, String reqUrl) {            Map<String, Integer> proxyIpMap = new HashMap<String, Integer>();            proxyIpMap.put(proxyIp, proxyPort);            checkProxyIp(proxyIpMap, reqUrl);      }            public static void main(String[] args) {                        Map<String, Integer> proxyIpMap = new HashMap<String, Integer>();            proxyIpMap.put(“114.80.136.112”, 7780);            proxyIpMap.put(“114.80.136.166”, 7780);            proxyIpMap.put(“114.80.136.167”, 7780);            proxyIpMap.put(“114.80.136.168”, 7780);            proxyIpMap.put(“114.80.136.169”, 7780);            proxyIpMap.put(“114.80.136.170”, 7780);            proxyIpMap.put(“114.80.136.171”, 7780);            proxyIpMap.put(“123.129.207.102”, 7780);            proxyIpMap.put(“123.129.207.100”, 7780);            proxyIpMap.put(“123.129.207.103”, 7780);            proxyIpMap.put(“123.129.207.104”, 7780);            proxyIpMap.put(“123.129.207.105”, 7780);            proxyIpMap.put(“123.129.207.108”, 7780);            proxyIpMap.put(“114.80.136.164”, 7780);            proxyIpMap.put(“123.129.207.107”, 7780);            proxyIpMap.put(“180.153.251.3”, 7780);            proxyIpMap.put(“180.153.251.4”, 7780);            proxyIpMap.put(“180.153.251.5”, 7780);            proxyIpMap.put(“180.153.251.6”, 7780);            proxyIpMap.put(“180.153.251.7”, 7780);            proxyIpMap.put(“180.153.251.8”, 7780);            proxyIpMap.put(“180.153.251.9”, 7780);            proxyIpMap.put(“180.153.251.10”, 7780);            proxyIpMap.put(“180.153.251.11”, 7780);            proxyIpMap.put(“180.153.251.12”, 7780);            proxyIpMap.put(“180.153.251.13”, 7780);            proxyIpMap.put(“180.153.251.14”, 7780);            proxyIpMap.put(“180.153.251.15”, 7780);            proxyIpMap.put(“180.153.251.16”, 7780);            proxyIpMap.put(“180.153.251.2”, 7780);            checkProxyIp(proxyIpMap, “http://t.sohu.com/new_index”);       }
