使用阿里雲介面進行銀行卡三要素實名認證

如今隨著網際網路產業的多元化發展，尤其是網際網路金融，O2O，共享經濟等新興商業形式的興起，企業對實名認證業務的資料形式和資料質量有了更高的需求。如今也衍生出銀行卡實名認證業務，通過介面將【銀行卡號、身份證號碼、姓名】上傳至阿里雲，再與銀行系統進行匹配，判斷資訊的一致性。
在使用介面服務的方面我推薦使用技術實力強大的阿里雲；

首先點選：【阿里雲API介面】獲取相應的訂單後在控制檯中可以得到您的appcode；

具體實現類：

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>();
        //最後在header中的格式(中間是英文空格)為Authorization:APPCODE 83359fd73fe94948385f570e3c139105
        headers.put("Authorization", "APPCODE " + appcode);
        //根據API的要求，定義相對應的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", "張三");


        try {
            /**

            HttpResponse response = HttpUtils.doPost(host, path, method, headers, querys, bodys);
