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;}
