2021年调用工商二维码退款查询接口

调用工商二维码退款查询接口   这里使用main方法调用

特别说明     二维码退款成功 使用RSA  退款就用RSA     

文档很坑直接写死RSA2

public class QrGenerateQueryTest {

    public static void main(String[] args) {
        
        String appId = "你公司的appid";
        String privateKey = "私钥";
        String icbcPulicKey = "公钥"

        //签名类型为RSA2时，需传入appid，私钥和网关公钥，签名类型使用定值IcbcConstants.SIGN_TYPE_RSA2，其他参数使用缺省值
        DefaultIcbcClient client = new DefaultIcbcClient(appId, IcbcConstants.SIGN_TYPE_RSA, privateKey, icbcPulicKey);


        QrcodeRejectQueryRequestV4 request = new QrcodeRejectQueryRequestV4();
        request.setServiceUrl("https://gw.open.icbc.com.cn/api/qrcode/reject/query/V4");

        QrcodeRejectQueryRequestV4.QrcodeRejectQueryRequestV4Biz bizContent = new QrcodeRejectQueryRequestV4.QrcodeRejectQueryRequestV4Biz();
        bizContent.setMerId("1******9"); // 商户线下档案编号(特约商户12位，特约部门15位)
        //bizContent.setCustId("1076dAbpBsrJXpI4J+/HXthaHj+mORib");//该字段非必输项
        bizContent.setOutTradeNo("Z******6");//该字段非必输项,out_trade_no和order_id选一项上送即可
       // bizContent.setOrderId("0*************1");//该字段非必输项,out_trade_no和order_id选一项上送即可
        bizContent.setRejectNo("X000000001");
        request.setBizContent(bizContent);

        QrcodeRejectQueryResponseV4 response;

        try {
            response = client.execute(request, "msgId");
            if (response.isSuccess()) {
                // 业务成功处理
                System.out.println("ReturnCode:" + response.getReturnCode());
                System.out.println("response:" + response);
            } else {
                // 失败
                System.out.println("失败");
                System.out.println("ReturnCode:" + response.getReturnCode());
                System.out.println("ReturnMsg:" + response.getReturnMsg());
            }
        } catch (IcbcApiException e) {
            e.printStackTrace();
        }
    }
}

运行结果 returncode  0 就是成功
