JAVA-银行卡归属地查询

文档地址：https://market.cloud.tencent.com/products/4730#tab=api

调用示例：

//传入银行卡号，返回银行名字
public String getCardInformation(String cardNumber) {
        String bankName= null;
        String path = "/get";
        String query = "cardNum="+cardNumber;
        String url = "https://service-mljqc6it-1255468759.ap-shanghai.apigateway.myqcloud.com/release";
        url = url + path + "?" + query;
        String result = SignAndSend.sendGet(url, secretId, secretKey);
        System.out.println(result);
        JSONObject jsonObject = JSONObject.parseObject(result);
        String code = (String) jsonObject.get("showapi_res_code");
        if (code.equals("0")){
            JSONObject jsonObject1 = JSONObject.parseObject(jsonObject.get("showapi_res_body").toString());
            //获取银行卡名
          bankName = (String)jsonObject1.get("bankName");
        }
        return bankName;
    }
