使用阿里云接口进行银行卡三要素实名认证（阿里云api接口java）

本文主要是介绍使用阿里云接口进行银行卡三要素实名认证（阿里云api接口java），对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

如今随着互联网产业的多元化发展，尤其是互联网金融，O2O，共享经济等新兴商业形式的兴起，企业对实名认证业务的数据形式和数据质量有了更高的需求。如今也衍生出银行卡实名认证业务，通过接口将【银行卡号、身份证号码、姓名】上传至阿里云，再与银行系统进行匹配，判断信息的一致性。
在使用接口服务的方面我推荐使用技术实力强大的阿里云；

首先点击：【阿里云API接口】获取相应的订单后在控制台中可以得到您的appcode；

此处依java版为实例，其他语言实例代码见产品页面中间接口文档。

具体实现类（java）：

public static void main(String[] args) {
        String host = "https://yunyidata3.market.alicloudapi.com";
        String path = "/bankAuthenticate3";
        String method = "POST";
        String appcode = "你自己的AppCode";
        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", "62155811111111111");
        bodys.put("idNo", "340421199922225555");
        bodys.put("name", "张三");
 
 
        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();
        }
    }
