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;
}
