创建订单流程

java

private HashNutClient hashnutClient;
private HashNutService hashNutService;
private final String chainCode="polygon-erc20";
private final String coinCode="usdt";
private final String merchantAddress="0xe1fd94f8874d698567e03f671a8c62e4e2e4be90";
private final String accessKeyId="01HRP45GKQX6X8HVVSNRAYNWDY";
private final String secretKey ="4ppKsAP3RPR8i5vKVqaXAMKW57GYvFiW";
private final String receiptAddress="0x202921baf49319c522f8885368ae96415b9ca414";

@Before
public void before(){
    hashnutClient = new HashNutClientImpl(secretKey, true);
    hashNutService = new HashNutServiceImpl(hashnutClient);
}

@Test
public void createOrder() throws HashNutException {
    final String merchantOrderId = UUID.randomUUID().toString();
    BigDecimal amount=new BigDecimal("1.13");
    CreateOrderResponse response = hashNutService.createOrder(new CreateOrderRequest.Builder()
            .withAccessKeyId(accessKeyId)
            .withMerchantOrderId(merchantOrderId)
            .withChainCode(chainCode)
            .withCoinCode(coinCode)
            .withAmount(amount)
            .withReceiptAddress(receiptAddress)
            .build());
    HashNutOrder order=response.getData();

    ObjectMapper objectMapper=new ObjectMapper();
    ObjectNode objectNode=objectMapper.createObjectNode();
    objectNode.put("payOrderId",order.getPayOrderId());
    objectNode.put("merchantOrderId",order.getMerchantOrderId());
    objectNode.put("accessSign",order.getAccessSign());
    objectNode.put("receiptAddress",order.getReceiptAddress());

    System.out.println(objectNode.toPrettyString());
}

查询订单

java

@Test
public void queryOrder() throws HashNutException {
    final String payOrderId="01HRKFC3H3BVZZAEEB1KM06SG0";
    final String mchOrderNo="3df2cd1d-5c2d-45a2-9ea7-fa47d6fec362";
    final String accessSign="F85EAB044144878CCA4C2C874A0E72042435D3D199AB44387D4F2559F40D7B88";

    QueryOrderResponse response=hashNutService.queryOrder(new QueryOrderRequest.Builder()
            .withPayOrderId(payOrderId)
            .withMerchantOrderId(mchOrderNo)
            .withAccessSign(accessSign)
            .build());
    HashNutOrder order=response.getData();
    System.out.println("get order payOrderId: " + order.getPayOrderId());
    System.out.println("get order merchantOrderId: " + order.getMerchantOrderId());
    System.out.println("get order accessSign: " + order.getAccessSign());
    System.out.println("get order amount: " + order.getAmount());
    System.out.println("get order state: " + OrderState.toString(order.getState()));
}

处理回调通知流程

java

// NOTE: read body as a String not json
private String readBodyFromRequest(HttpServletRequest request){
    try{
        InputStream inputStream = request.getInputStream();
        BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
        StringBuilder requestBody = new StringBuilder();
        String line;

        while ((line = reader.readLine()) != null) {
            requestBody.append(line);
        }
        return requestBody.toString();
    }catch (Exception e){
        return null;
    }
}

@PostMapping(value="/hashNutWebhook")
public void hashNutWebhook(HttpServletRequest request,
                      HttpServletResponse response) throws Exception {
    log.info("hashnut notify process start");

    // verify sign, NOTE: must read body as a String not json
    String body=readBodyFromRequest(request);
    if(!verifyWebhook(request,body)){
        log.info("hashnut notify process failed");
        outResult(response,"failed");
        return;
    }

    // query pay order detail info and process pay order
    JsonNode jsonNode=objectMapper.readTree(body);
    String payOrderId=jsonNode.get("payOrderId").asText();
    String merchantOrderId=jsonNode.get("merchantOrderId").asText();
    String accessSign=jsonNode.get("accessSign").asText();

    QueryOrderResponse hashnutResponse=hashNutService.queryOrder(new QueryOrderRequest.Builder()
            .withPayOrderId(payOrderId)
            .withMerchantOrderId(merchantOrderId)
            .withAccessSign(accessSign)
            .build());
    HashNutOrder hashNutOrder=hashnutResponse.getData();

    if(hashNutOrder.getState() >= OrderState.SUCCESS){
        log.info("hashnut pay order success");
        goodsOrderService.updateOrderState(merchantOrderId, Constant.GOODS_ORDER_STATUS_SUCCESS);
    }
    if(hashNutOrder.getState() < OrderState.INIT){
        log.info("hashnut pay order failed state {}",hashNutOrder.getState());
        goodsOrderService.updateOrderState(merchantOrderId, Constant.GOODS_ORDER_STATUS_FAIL);
    }
    log.info("hashnut notify process success");
    outResult(response,"success");
}
