Question

我正在使用paypal NVP和NVP响应键值对字符串

示例

TOKEN = EC-3XXXXXXXXXXX154J＆安培; BILLINGAGREEMENTACCEPTEDSTATUS = 1＆安培; CHECKOUTSTATUS = PaymentActionNotInitiated＆安培; TIMESTAMP = 2012-07-10T11：45：59Z＆安培;的correlationID = ecf9bfe9b1168＆安培; ACK =成功＆安培; VERSION = 64.0＆安培; BUILD = 3242673＆安培; EMAIL = govind_1341920205_per @ gmail.com＆安培; PAYERID = 3V85HKW32SXKG＆安培; PAYERSTATUS =验证＆安培; FIRSTNAME =戈文德＆安培; LASTNAME =马尔维亚＆安培; COUNTRYCODE = US＆安培; SHIPTONAME =戈文德 Malviya＆amp; SHIPTOSTREET = 1 Main St＆amp; SHIPTOCITY = San 何塞＆放大器; SHIPTOSTATE = CA＆放大器; SHIPTOZIP = 95131＆放大器; SHIPTOCOUNTRYCODE = US＆放大器; SHIPTOCOUNTRYNAME =美国 States＆amp; ADDRESSSTATUS =已确认＆amp; CURRENCYCODE = USD＆amp; AMT = 30.90＆amp; SHIPPINGAMT = 0.00＆amp; HANDLINGAMT = 0.00＆amp; TAXAMT = 0.00＆amp; DESC = test EC 付款＆安培; INSURANCEAMT = 0.00＆安培; SHIPDISCAMT = 0.00＆安培; PAYMENTREQUEST_0_CURRENCYCODE = USD＆安培; PAYMENTREQUEST_0_AMT = 30.90＆安培; PAYMENTREQUEST_0_SHIPPINGAMT = 0.00＆安培; PAYMENTREQUEST_0_HANDLINGAMT = 0.00＆安培; PAYMENTREQUEST_0_TAXAMT = 0.00＆安培; PAYMENTREQUEST_0_DESC =测试 EC 付款＆安培; PAYMENTREQUEST_0_INSURANCEAMT = 0.00＆安培; PAYMENTREQUEST_0_SHIPDISCAMT = 0.00＆安培; PAYMENTREQUEST_0_INSURANCEOPTIONOFFERED =假安培; PAYMENTREQUEST_0_SHIPTONAME =戈文德 Malviya＆amp; PAYMENTREQUEST_0_SHIPTOSTREET = 1 Main ST＆安培; PAYMENTREQUEST_0_SHIPTOCITY =散何塞＆放大器; PAYMENTREQUEST_0_SHIPTOSTATE = CA＆放大器; PAYMENTREQUEST_0_SHIPTOZIP = 95131＆放大器; PAYMENTREQUEST_0_SHIPTOCOUNTRYCODE = US＆放大器; PAYMENTREQUEST_0_SHIPTOCOUNTRYNAME =美国国＆安培; PAYMENTREQUESTINFO_0_ERRORCODE = 0

我想在强类型数据中对其进行去序列化，就像JavaScriptSerializer为json字符串做的那样。请不要使用字典提供解决方案我想避免魔术字符串，我可以在每个属性上添加属性。

我的班级是

 public class GetExpressCheckoutDetailsResponse : IPaypalResponse
    {
        public string Token { get; set; }
        public string BillingAgreementAcceptedStatus { get; set; }
        public string CheckoutStatus { get; set; }
        public string Timestamp { get; set; }
        public string CorrelationID { get; set; }
        public Status Acknowledgement { get; set; }
        public string Version { get; set; }
        public string Build { get; set; }
        public string Email { get; set; }
        public string PayerID { get; set; }
        public string PayerStatus { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string CountryCode { get; set; }
        public string ShiptoName { get; set; }
        public string ShiptoStreet { get; set; }
        public string ShipToCity { get; set; }
        public string ShipToState { get; set; }
        public string ShipToZip { get; set; }
        public string ShipToCountryCode { get; set; }
        public string ShipToCountryName { get; set; }
        public string AddressStatus { get; set; }
        public string CurrencyCode { get; set; }
        public string Amount { get; set; }
        public string ShippingAmount { get; set; }
        public string HandlingAmount { get; set; }
        public string TaxAmount { get; set; }
        public string Description { get; set; }
        public string InsuranceAmount { get; set; }
        public string ShipdiscAmount { get; set; }
        public string PaymentRequestCurrencycode { get; set; }
        public string PaymentRequestAmount { get; set; }
        public string PaymentRequestShippingAmount { get; set; }
        public string PaymentRequestHandlingAmount { get; set; }
        public string PaymentRequestTaxAmount { get; set; }
        public string PaymentRequestDescription { get; set; }
        public string PaymentRequestInsuranceAmount { get; set; }
        public string PaymentRequestShipdiscAmount { get; set; }
        public string PaymentRequestInsuranceOptionOffered { get; set; }
        public string PaymentRequestShipToName { get; set; }
        public string PaymentRequestShipToStreet { get; set; }
        public string PaymentRequestShipToCity { get; set; }
        public string PaymentRequestShipToState { get; set; }
        public string PaymentRequestShipToZip { get; set; }
        public string PaymentRequestShipToCountryCode { get; set; }
        public string PaymentRequestShipToCountryName { get; set; }
        public string PaymentRequestInfoErrorCode { get; set; }
    }

Answer 1

您可以使用LINQ将数据提取到Dictionary<TKey, TValue>，然后您可以使用它来映射您班级中的数据，例如

。

var paypalResponse = "...";
var data = paypalResponse.Split('&') 
                         .Select(x => x.Split('=')) 
                         .ToDictionary(x => x[0], x => x[1]);

然后你可以将它传递给GetExpressCheckoutDetailsResponse类的构造函数，甚至可以在其中执行此操作，例如。

public class GetExpressCheckoutDetailsResponse : IPaypalResponse
{
    public GetExpressCheckoutDetailsResponse(Dictionary<string, string> data)
    {
        this.Token = data["TOKEN"];
        this.BillingAgreementAcceptedStatus = data["BILLINGAGREEMENTACCEPTEDSTATUS"];
        ...
    }
}

对于这样的事情使用反射可能比它的价值更麻烦，因为您的属性不完全匹配，因此您需要为每个属性添加元数据属性。

Answer 2

您可以使用HttpUtility.ParseQueryString将字符串转换为NameValueCollection。其余的只是reflection

string responseString = "TOKEN=EC......";
var dict = HttpUtility.ParseQueryString(responseString);
GetExpressCheckoutDetailsResponse respObj = new GetExpressCheckoutDetailsResponse();
foreach (var p in respObj.GetType().GetProperties())
{
    p.SetValue(respObj, dict[p.Name]);
}

//respObj is ready to use

Answer 3

因此，由于您的问题没有现成的反序列化器，您应该执行以下操作：

为每个属性添加属性，代表paypal的响应'。
反映类实例的属性并将其缓存到Dictionary<string, PropertyInfo>，其中字符串是属性的值。
在paypal响应中迭代"some string".Split(..)方法的结果，收集字符串和值，然后将它们存储到您应该在字典中查找的相应属性中。

Answer 4

在您的特定情况下，而不是重新发明轮子;你如何使用PayPal SDK？

http://paypal.github.io/sdk/

你想要的是Express Checkout SDK for C#

它已经拥有了您需要的所有字段以及正确的数据类型，它还具有在几个简单的函数调用后自动完成响应的所有调用/解析的附加好处。

手工构建自己的API调用并解析响应并不是最好的方法。当然，最终你将会让它发挥作用，但在你这样做之前，这将是一个耗时且容易出错的过程......
