2.实现

2.1代码实现：

2.2.2相关依赖：

 public static void main(String[] args) {
        String host = "https://zid.market.alicloudapi.com";
        String path = "/idcheck/Post";
        String method = "POST";
        String appcode = "ab68c2e9dbc04b37a27dc514c8fd4612";
        Map<String, String> headers = new HashMap<String, String>();
        //最后在header中的格式(中间是英文空格)为Authorization:APPCODE 83359fd73fe94948385f570e3c139105
        headers.put("Authorization", "APPCODE " + appcode);
        //根据API的要求，定义相对应的Content-Type
        headers.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
        Map<String, String> querys = new HashMap<String, String>();
        Map<String, String> bodys = new HashMap<String, String>();
        bodys.put("cardNo", "xxxxxxxxxxxxxxxxxx");
        bodys.put("realName", "xxx");
        try {
            HttpResponse response = HttpUtils.doPost(host, path, method, headers, querys, bodys);
            System.out.println(response.toString());
            //获取response的body
            System.out.println(EntityUtils.toString(response.getEntity()));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

2.2返回值解释：

2.3转换格式 用于返回给前端显示认证结果：

String result=EntityUtils.toString(response.getEntity());
            // 解析成Map对象

            //三个Map
            //全体
            Map<String,Object> responseMap = stringToJsonToMap(result);
            //查询结果
            Map<String,Object> resultMap = stringToJsonToMap(String.valueOf(responseMap.get("result")));
            //详细信息
            Map<String,Object> idCardInforMap = stringToJsonToMap(String.valueOf(resultMap.get("IdCardInfor")));
            traverseMap(responseMap);
            traverseMap(resultMap);
            traverseMap(idCardInforMap);
