使用 hutool 工具包来发起 http 请求，以及后续爬虫功能

 参考文档:Hutool

<dependency>
            <groupId>com.xiaoleilu</groupId>
            <artifactId>hutool-all</artifactId>
            <version>3.2.3</version>
        </dependency>

2.mian method

 public static void main(String[] args) throws Exception{
        String bankNo = "银行卡号";
        //银行代码请求接口 url
        String url = "https://ccdcapi.alipay.com/validateAndCacheCardInfo.json?_input_charset=utf-8&cardNo="+bankNo+"&cardBinCheck=true";
        //发送请求，得到 josn 类型的字符串
        String result = HttpUtil.get(url);
        // 转为 Json 对象
        JSONObject json = new JSONObject(result);
        //获取到 bank 代码
        String bank = String.valueOf(json.get("bank"));
        //爬取支付宝银行合作商页面
        String listContent = HttpUtil.get("http://ab.alipay.com/i/yinhang.htm","gb2312");
        //过滤得到需要的银行名称
        List<String> titles = ReUtil.findAll("<span title=\"(.*?)\" class=\"icon "+bank+"\">(.*?)</span>", listContent, 2);
        for (String title : titles) {
            //打印银行名称
