反序列化鍵值串

Question

我使用貝寶NVP和NVP在鍵值對串做出響應

例

TOKEN = EC-3XXXXXXXXXXX154J & BILLINGAGREEMENTACCEPTEDSTATUS = 1 & CHECKOUTSTATUS = PaymentActionNotInitiated & TIMESTAMP = 2012 -07-10T11：45：59Z &的correlationID = ecf9bfe9b1168 & ACK =成功& VERSION = 64.0 & BUILD = 3242673 & EMAIL=govind_1341920205_per@gmail.com & PAYERID = 3V85HKW32SXKG & PAYERSTATUS =驗證& FIRSTNAME =戈文德& LASTNAME =馬爾維亞& COUNTRYCODE = US & SHIPTONAME =戈文德 馬爾維亞& SHIPTOSTREET = 1 MAIN ST & SHIPTOCITY =聖 聖何塞& SHIPTOSTATE = CA & SHIPTOZIP = 95131 & SHIPTOCOUNTRYCODE = US & SHIPTOCOUNTRYNAME =美國 美國& ADDRESSSTATUS =確認& CURRENCYCODE = USD & AMT = 30.90 & SHIPPINGAMT = 0.00 & HANDLINGAMT = 0.00 & TAXAMT = 0.00 & DESC =測試EC 付款& INSURANCEAMT = 0.00 & SHIPDISCAMT = 0.00 & PAYMENTREQUEST_0_CURRENCYCODE = USD & PAYMENTREQUEST_0_AMT = 30.90 & PAYMENTREQUEST_0_SHIPPINGAMT = 0.00 & PAYMENTREQUEST_0_HANDLINGAMT = 0.00 & PAYMENTREQUEST_0_TAXAMT = 0.00 & PAYMENTREQUEST_0_DESC =測試 EC 付款& PAYMENTREQUEST_0_INSURANCEAMT = 0.00 & PAYMENTREQUEST_0_SHIPDISCAMT = 0.00 & PAYMENTREQUEST_0_INSURANCEOPTIONOFFERED = false & PAYMENTREQUEST_0_SHIPTONAME = Govind Malviya & PAYMENTREQUEST_0_SHIPTOSTREET = 1主 聖& PAYMENTREQUEST_0_SHIPTOCITY =聖 聖何塞& PAYMENTREQUEST_0_SHIPTOSTATE = CA & PAYMENTREQUEST_0_SHIPTOZIP = 95131 & PAYMENTREQUEST_0_SHIPTOCOUNTRYCODE = US & PAYMENTREQUEST_0_SHIPTOCOUNTRYNAME =美國 美國& PAYMENTREQUESTINFO_0_ERRORCODE = 0

我想desrialize它的強類型數據，就像JavaScriptSerializer爲json字符串做的一樣。請不要使用字典提供解決方案我想避免魔術字符串，我可以在每個屬性上添加屬性。

我的班級

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 PaymentRequestInfoErrorCode { get; set; } 
    } 

Answer 1

您可以使用HttpUtility.ParseQueryString將您的字符串轉換爲NameValueCollection。其餘的只是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 2

所以，因爲沒有現成的使用deserializator對於您的問題，您應該做到以下幾點：

1. 屬性添加到每個代表的財產貝寶的迴應「。
2. 反映類實例的屬性並將它們緩存到Dictionary<string, PropertyInfo>，其中字符串是屬性的值。
3. 通過"some string".Split(..)在PayPal響應中迭代方法的結果，收集字符串和值，然後將它們存儲到您應該在字典中查找的相應屬性中。

Answer 3

您可以使用LINQ將數據提取到Dictionary<TKey, TValue>，然後您可以使用它來映射班級中的數據，例如

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

然後，您可以通過這個到您的GetExpressCheckoutDetailsResponse類的構造函數，甚至爲此它裏面例如

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

使用這樣的事情，不值得爲你的屬性不完全匹配，所以你需要添加元數據屬性每個屬性的可能是更多的麻煩反思。

Answer 4

在你的具體情況，而不是重新發明輪子;您如何使用PayPal SDK？

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

你想要的是Express Checkout SDK for C#

它已經需要用正確的數據類型的所有字段，它具有自動響應的所有通話/分析的好處在幾個簡單的函數調用之後。

手動構建自己的API調用並解析響應不是最好的方法。當然，最終你會得到它的工作，但直到你這樣做，這將是一個耗時和容易出錯的過程...
