获取使用Java中PayPal API完成付款的卡详细信息

Question

我正在使用 paypal api 类，用于在 java 我的应用程序中进行付款。我的贝宝（Paypal）砂盒帐户中有三张卡，这些卡是主，Visa和American Express。

我要在付款之前设置所需的信息，我正在为相同的代码提供代码。

// ###Details
        Details details = new Details();
        details.setShipping("0");
        details.setSubtotal("1");
        details.setTax("0");
        // ###Amount
        Amount amount = new Amount();
        amount.setCurrency(jobLine.getCurrency());
        amount.setTotal("1");
        amount.setDetails(details);
        // ###Transaction
        Transaction transaction = new Transaction();
        transaction.setAmount(amount);
        transaction.setDescription("This is the payment transaction for vetjobs.com.au");
        // ### Items
        Item item = new Item();
        item.setName("vetjob post job").setQuantity("1").setCurrency(jobLine.getCurrency()).setPrice("1");
        ItemList itemList = new ItemList();
        List<Item> items = new ArrayList<Item>();
        items.add(item);
        itemList.setItems(items);
        transaction.setItemList(itemList);
        List<Transaction> transactions = new ArrayList<Transaction>();
        transactions.add(transaction);
        Payer payer = new Payer();
        payer.setPaymentMethod("paypal");
        // ###Payment
        Payment payment = new Payment();
        payment.setIntent("sale");
        payment.setPayer(payer);
        payment.setTransactions(transactions);

因此，在付款之前未决定卡，这将在付款后知道。

现在，我已经使用Visa付款了，我想在JSP页面上显示该卡名称。那么如何检索这些细节？

Answer 1

我解决了您的查询。这是答案

功能以获取卡细节。

public Map<String, Object> getCardDetails() throws PayPalRESTException {
        Map<String, Object> response = new HashMap<String, Object>();
        try {
            APIContext context = new APIContext(clientId, clientSecret, "sandbox");
            CreditCard creditCard = CreditCard.get(context, "CARD-9D2462350Y753123NLS4YVTY");
            response.put("status", "sucsess");
            response.put("Details", creditCard);
            return response;
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

API获取卡详细信息

@RequestMapping(value = "cardDetails", method = RequestMethod.GET)
    public ResponseEntity<Map<String, Object>> cardDetails() {
        Map<String, Object> response = new HashMap<String, Object>();
        Map<String, Object> data = new HashMap<String, Object>();
        try {
            Map<String, Object> cardResponse = paypalVaultPaymentService.getCardDetails();
            String json = cardResponse.get("Details").toString();
            Map<String, Object> map = toMap(new JSONObject(json));
            data.put("cardDetails", map);
            response.put("data", data);
            response.put("status", "OK");
            response.put("code", "200");
            response.put("message", "Card Details Found successfully.");
            return new ResponseEntity<Map<String, Object>>(response, HttpStatus.OK);
        } catch (Exception e) {
            e.printStackTrace();
            response.put("status", "ERROR");
            response.put("code", "500");
            response.put("message", "Something went wrong");
            return new ResponseEntity<Map<String, Object>>(response, HttpStatus.INTERNAL_SERVER_ERROR);
        }
    }
public static Map<String, Object> toMap(JSONObject object) throws JSONException {
        Map<String, Object> map = new HashMap<String, Object>();
        Iterator<String> keysItr = object.keys();
        while (keysItr.hasNext()) {
            String key = keysItr.next();
            Object value = object.get(key);
            if (value instanceof JSONArray) {
                value = toList((JSONArray) value);
            }
            else if (value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }
            map.put(key, value);
        }
        return map;
    }
    public static List<Object> toList(JSONArray array) throws JSONException {
        List<Object> list = new ArrayList<Object>();
        for (int i = 0; i < array.length(); i++) {
            Object value = array.get(i);
            if (value instanceof JSONArray) {
                value = toList((JSONArray) value);
            }
            else if (value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }
            list.add(value);
        }
        return list;
    }

Answer 2

存储信用卡时，它会返回卡_ ID，例如" card-1sw33690th184423ckm2z"，您可以使用card_id获取卡详细信息。尝试此请求以获取卡详细信息
