玩！框架支付处理（电子商务/ PayPal）

Question

我正在寻找建立一个应用程序，用户将有能力从我的网站购买产品。购买将包括他们正在购买的实物商品，运费，税金（如果适用）等。我知道PayPal有许多可用于付款的选项，其中之一是Web服务，另一个只是重定向到他们的网站。我想为用户的体验，以尽可能无缝的，但我并不想进入存储信用卡等业务

如果我做处理我的服务器上的事务（与安全连接/ SSL ），我是否会将信用卡信息传递给他们的服务进行处理？

玩！ Framework v1.2对WebServices有很好的支持。 Play没有贝宝模块，但代码不太复杂。我为我们的工作板（www.express-board.fr）实施了Web服务解决方案，并花了3天时间。

第一：用户总是重定向到贝宝网站。没有贝宝客户端面临的解决方案。如果您使用Webservice解决方案（developer.paypal.com），则可以使用您的徽标自定义贝宝网页。不是最好的解决方案，但它有效。

在播放方面，这里是一个检验方法的样本代码，使用贝宝的Web服务：

public static void checkout() { 
    Double amount = Double.parseDouble(session.get("amount")); 
    Long userId = Long.parseLong(session.get("user-id")); 
    User user = User.findById(userId); 
    if (user != null) { 
     renderArgs.put("user", user); 
    } 

    // we calculate the net and gross amount with French V.A.T (19.6%) 
    BigDecimal amountBD = new BigDecimal(amount * 1.196); 
    BigDecimal netAmountBD = new BigDecimal(amount); 
    BigDecimal taxAmountBD = amountBD.subtract(netAmountBD); 

    String netAmount = netAmountBD.setScale(2, BigDecimal.ROUND_HALF_EVEN).toString(); 
    String totalAmount = amountBD.setScale(2, BigDecimal.ROUND_HALF_EVEN).toString(); 
    String taxAmount = taxAmountBD.setScale(2, BigDecimal.ROUND_HALF_EVEN).toString(); 

    String subject="Publication d'une offre d'emploi"; 


// Paypal Web service callback executed by Play! 
// I have a paypal.api.server configuration property with prod and sandbox server 

    WS.HttpResponse res = WS.url(Play.configuration.get("paypal.api.server").toString() + 
      "&USER=%s" +

    String message = res.getString();

    if (paypalResponse.isSuccess()) {

     payment.taxAmount = taxAmount; 
     payment.token = paypalResponse.getToken(); 
     payment.correlationID = paypalResponse.getCorrelationID(); 
     payment.save(); 

     redirect(Play.configuration.get("paypal.api.http").toString() + "/cgi-bin/webscr?cmd=_express-checkout&token=" + paypalResponse.getToken()); 
    } 

    Logger.error("Error on SetExpressCheckout with: "); 
    for (String tokens : message.split("&")) { 
     try { 
      Logger.error(URLDecoder.decode(tokens, "UTF-8")); 
     } catch (UnsupportedEncodingException e) { 
     } 
    } 

    error("Error from Paypal"); 

} 

希望它可以帮助
