paypal Java 查询支付状态

查询支付状态

这里只讲查询支付状态的，获得 token 什么的比较简单，这里就不讲解了。
这里是根据按钮进行对接的，也就是这篇

根据回调参数 txn_id 查询支付状态

官网有Show captured payment details
postman
只需要带个 token 就行了

代码如下

    public static ServiceResult<String> getPaypalPaymentResult(String txnId) {
        if (StringUtils.isBlank(txnId)) {
            return ServiceResult.asFail("The transaction number does not exist!");
        }
        LogUtils.PAYPAL_LOG.info("get Paypal Payment Result txnId:" + txnId);
        Request request = new Request.Builder()
                .url(GET_PAYPAL_PAYMENT_STATUS_URL + txnId)
                .get()
                .addHeader("Authorization", "Bearer " + getPaypalToken())
                .addHeader("Content-Type", "application/json")
                .build();
        String responseStr = "";
        try {
            responseStr = paypalClient.newCall(request).execute().body().string();
            LogUtils.PAYPAL_LOG.info("get Paypal Payment Status request:" + request.toString() + " response String:" + responseStr);
            return ServiceResult.asSuccess(responseStr, "response");
        } catch (Exception e) {
            LogUtils.ERROR_LOGGER.error("get Paypal Payment Status request send failed request :" + request.toString());
        }
        return ServiceResult.asFail("get Paypal Payment Status failed!");
    }

根据按钮 sdk 返回的 orderID 查询订单信息

官网有Show order details
postman

如果不知道OrderID在哪里获取，请点这里

代码如下：

    public static ServiceResult<PaypalOrderModel> getPaypalOrderDetails(String orderId) {
        if (StringUtils.isBlank(orderId)) {
            return ServiceResult.asFail("orderId is required!");
        }
        LogUtils.PAYPAL_LOG.info("get Paypal order Details orderId:" + orderId);
        Request request = new Request.Builder()
                .url(GET_PAYPAL_ORDER_STATUS_URL + orderId)
                .get()
                .addHeader("Authorization", "Bearer " + getPaypalToken())
                .addHeader("Content-Type", "application/json")
                .build();
        ServiceResult result = ServiceResult.asFail("");
        try {
            String responseStr = paypalClient.newCall(request).execute().body().string();
            LogUtils.PAYPAL_LOG.info("get Paypal order Details request:" + request.toString() + " response String:" + responseStr);
            result.success = PaypalOrderStatus.isPaymentSuccess(responseStr);
            PaypalOrderModel paypalOrderModel = jsonConvertOrderModel(responseStr);
            result.obj = paypalOrderModel;
        } catch (Exception e) {
            LogUtils.ERROR_LOGGER.error("get Paypal order Details request send failed request :" + request.toString() + ", order Details transfer PaypalOrderModel failed!");
        }
        return result;
    }
