C# 将大型httpresponse流转换为JSON字符串？

问题背景:

更新：

我仍然不知道如何从这个回复中提取相关信息。我已经尝试将响应类型设置为JSON，但仍然收到如下所示的响应。我已经考虑了关于使用NameValueCollection所说的话，但仍然看不出这对如此大的响应有什么帮助。理想情况下，我希望将其映射到某种对象结构，它不一定是JSON

问题:

我目前正在使用PayPalAPI的“ExpressCheckout”方法，允许用户在我的测试站点上为项目付费。来自API的HTTP响应提供了一个大型响应，其中包含我需要提取的关键信息，例如买家地址、付款是否成功等

问题是：

目前，我被困在如何处理响应上。理想情况下，我会将数据转换为JSON字符串，然后使用Newtonsoft将数据映射到C类，从而允许轻松访问数据。以下是Httpresponse的一个示例：

TOKEN=EC%2XXXXXXXXXXXXXXXXXR&BILLINGAGREEMENTACCEPTEDSTATUS=0&CHECKOUTSTATUS=PaymentActionNotInitiated&TIMESTAMP=2015%2d01%2d02T21%3a11%3a30Z&CORRELATIONID=ab184fdba7a30&ACK=Success&VERSION=88%2e0&BUILD=14443165&EMAIL=test%40aol%2ecom&PAYERID=3XXXXXXXXXX4N&PAYERSTATUS=verified&BUSINESS=Test%20Biz%27s%20Test%20Store&FIRSTNAME=Joe&LASTNAME=King&COUNTRYCODE=GB&SHIPTONAME=Joe%20King%27s%20Test%20Store&SHIPTOSTREET=1%20Main%20Terrace&SHIPTOCITY=Wolverhampton&SHIPTOSTATE=West%20Midlands&SHIPTOZIP=W12%204LQ&SHIPTOCOUNTRYCODE=GB&SHIPTOCOUNTRYNAME=United%20Kingdom&ADDRESSSTATUS=Confirmed&CURRENCYCODE=GBP&AMT=15%2e56&ITEMAMT=15%2e56&SHIPPINGAMT=0%2e00&HANDLINGAMT=0%2e00&TAXAMT=0%2e00&INSURANCEAMT=0%2e00&SHIPDISCAMT=0%2e00&L_NAME0=ItemOne&L_QTY0=4&L_TAXAMT0=0%2e00&L_AMT0=3%2e89&L_ITEMWEIGHTVALUE0=%20%20%200%2e00000&L_ITEMLENGTHVALUE0=%20%20%200%2e00000&L_ITEMWIDTHVALUE0=%20%20%200%2e00000&L_ITEMHEIGHTVALUE0=%20%20%200%2e00000&PAYMENTREQUEST_0_CURRENCYCODE=GBP&PAYMENTREQUEST_0_AMT=15%2e56&PAYMENTREQUEST_0_ITEMAMT=15%2e56&PAYMENTREQUEST_0_SHIPPINGAMT=0%2e00&PAYMENTREQUEST_0_HANDLINGAMT=0%2e00&PAYMENTREQUEST_0_TAXAMT=0%2e00&PAYMENTREQUEST_0_INSURANCEAMT=0%2e00&PAYMENTREQUEST_0_SHIPDISCAMT=0%2e00&PAYMENTREQUEST_0_INSURANCEOPTIONOFFERED=false&PAYMENTREQUEST_0_SHIPTONAME=Joe%20King%27s%20Test%20Store&PAYMENTREQUEST_0_SHIPTOSTREET=1%20Main%20Terrace&PAYMENTREQUEST_0_SHIPTOCITY=Wolverhampton&PAYMENTREQUEST_0_SHIPTOSTATE=West%20Midlands&PAYMENTREQUEST_0_SHIPTOZIP=W12%204LQ&PAYMENTREQUEST_0_SHIPTOCOUNTRYCODE=GB&PAYMENTREQUEST_0_SHIPTOCOUNTRYNAME=United%20Kingdom&PAYMENTREQUEST_0_ADDRESSSTATUS=Confirmed&L_PAYMENTREQUEST_0_NAME0=ItemOne&L_PAYMENTREQUEST_0_QTY0=4&L_PAYMENTREQUEST_0_TAXAMT0=0%2e00&L_PAYMENTREQUEST_0_AMT0=3%2e89&L_PAYMENTREQUEST_0_ITEMWEIGHTVALUE0=%20%20%200%2e00000&L_PAYMENTREQUEST_0_ITEMLENGTHVALUE0=%20%20%200%2e00000&L_PAYMENTREQUEST_0_ITEMWIDTHVALUE0=%20%20%200%2e00000&L_PAYMENTREQUEST_0_ITEMHEIGHTVALUE0=%20%20%200%2e00000&PAYMENTREQUESTINFO_0_ERRORCODE=0

如果有人能给我一个简单的方法将这些数据映射到一个C对象，那就太好了。

您想要JSON格式的数据有什么具体的原因吗？若它不是必需的，若您可以使用键值对，那个么这里有一种方法可以将响应作为键值对进行处理

public partial class Form1 : Form
{
    Dictionary<string, string> processedResponse = null;
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        string rawResponse = "TOKEN=EC%2XXXXXXXXXXXXXXXXXR&BILLINGAGREEMENTACCEPTEDSTATUS=0&CHECKOUTSTATUS=PaymentActionNotInitiated&TIMESTAMP=2015%2d01%2d02T21%3a11%3a30Z&CORRELATIONID=ab184fdba7a30&ACK=Success&VERSION=88%2e0&BUILD=14443165&EMAIL=test%40aol%2ecom&PAYERID=3XXXXXXXXXX4N&PAYERSTATUS=verified&BUSINESS=Test%20Biz%27s%20Test%20Store&FIRSTNAME=Joe&LASTNAME=King&COUNTRYCODE=GB&SHIPTONAME=Joe%20King%27s%20Test%20Store&SHIPTOSTREET=1%20Main%20Terrace&SHIPTOCITY=Wolverhampton&SHIPTOSTATE=West%20Midlands&SHIPTOZIP=W12%204LQ&SHIPTOCOUNTRYCODE=GB&SHIPTOCOUNTRYNAME=United%20Kingdom&ADDRESSSTATUS=Confirmed&CURRENCYCODE=GBP&AMT=15%2e56&ITEMAMT=15%2e56&SHIPPINGAMT=0%2e00&HANDLINGAMT=0%2e00&TAXAMT=0%2e00&INSURANCEAMT=0%2e00&SHIPDISCAMT=0%2e00&L_NAME0=ItemOne&L_QTY0=4&L_TAXAMT0=0%2e00&L_AMT0=3%2e89&L_ITEMWEIGHTVALUE0=%20%20%200%2e00000&L_ITEMLENGTHVALUE0=%20%20%200%2e00000&L_ITEMWIDTHVALUE0=%20%20%200%2e00000&L_ITEMHEIGHTVALUE0=%20%20%200%2e00000&PAYMENTREQUEST_0_CURRENCYCODE=GBP&PAYMENTREQUEST_0_AMT=15%2e56&PAYMENTREQUEST_0_ITEMAMT=15%2e56&PAYMENTREQUEST_0_SHIPPINGAMT=0%2e00&PAYMENTREQUEST_0_HANDLINGAMT=0%2e00&PAYMENTREQUEST_0_TAXAMT=0%2e00&PAYMENTREQUEST_0_INSURANCEAMT=0%2e00&PAYMENTREQUEST_0_SHIPDISCAMT=0%2e00&PAYMENTREQUEST_0_INSURANCEOPTIONOFFERED=false&PAYMENTREQUEST_0_SHIPTONAME=Joe%20King%27s%20Test%20Store&PAYMENTREQUEST_0_SHIPTOSTREET=1%20Main%20Terrace&PAYMENTREQUEST_0_SHIPTOCITY=Wolverhampton&PAYMENTREQUEST_0_SHIPTOSTATE=West%20Midlands&PAYMENTREQUEST_0_SHIPTOZIP=W12%204LQ&PAYMENTREQUEST_0_SHIPTOCOUNTRYCODE=GB&PAYMENTREQUEST_0_SHIPTOCOUNTRYNAME=United%20Kingdom&PAYMENTREQUEST_0_ADDRESSSTATUS=Confirmed&L_PAYMENTREQUEST_0_NAME0=ItemOne&L_PAYMENTREQUEST_0_QTY0=4&L_PAYMENTREQUEST_0_TAXAMT0=0%2e00&L_PAYMENTREQUEST_0_AMT0=3%2e89&L_PAYMENTREQUEST_0_ITEMWEIGHTVALUE0=%20%20%200%2e00000&L_PAYMENTREQUEST_0_ITEMLENGTHVALUE0=%20%20%200%2e00000&L_PAYMENTREQUEST_0_ITEMWIDTHVALUE0=%20%20%200%2e00000&L_PAYMENTREQUEST_0_ITEMHEIGHTVALUE0=%20%20%200%2e00000&PAYMENTREQUESTINFO_0_ERRORCODE=0";
        //Process response
        processedResponse = ProcessResponse(rawResponse);

        //Use received data e.g.

        //Get First name
        string fName = GetRecordValue("FIRSTNAME");

        //Get Last name
        string lName = GetRecordValue("LASTNAME");
    }

    private Dictionary<string,string> ProcessResponse(string response)
    {
        Dictionary<string, string> responseData = new Dictionary<string, string>();

        if(!string.IsNullOrWhiteSpace(response))
        {
            string[] firstPass = response.Split(new char[] { '&' });
            foreach(string pair in firstPass)
            {
                string[] secondPass = pair.Split(new char[] { '=' });
                if(secondPass!=null && secondPass.Length>0)
                {
                    responseData.Add(secondPass[0].Trim(), secondPass[1].Trim());
                }
            }
        }
        return responseData;
    }

    private string GetRecordValue(string record)
    {
        string recordValue = null;
        if(processedResponse!=null)
        {
            if(!string.IsNullOrWhiteSpace(record) && processedResponse.ContainsKey(record))
            {
                recordValue= processedResponse[record];
            }
        }
        return recordValue;
    }
}

仍然不确定将其作为NameValueCollection处理有什么问题

例如

这里正在处理的是响应字符串，而不是请求，因此您将无法使用request.QueryString检索详细信息

如评论中所述：

string rawResponse = "TOKEN=EC%2XXXXXXXXXXXXXXXXXR&BILLINGAGREEMENTACCEPTEDSTATUS=0&CHECKOUTSTATUS=PaymentActionNotInitiated&TIMESTAMP=2015%2d01%2d02T21%3a11%3a30Z&CORRELATIONID=ab184fdba7a30&ACK=Success&VERSION=88...."

var foo = HttpUtility.ParseQueryString(rawResponse); //NameValueCollection
var bar = foo["FIRSTNAME"]; //Joe

为了能够使用Json.Net将响应转换为模型，您需要paypal向您发送Json。您发布的不是Json，所以需要手动解析。这是来自服务器端调用吗？您可以参考：将其作为NameValueCollection进行映射有什么问题？为什么额外的JSON转换非常理想？这是一个很好的答案，谢谢。我现在有一个填充的NameValueCollection可以使用。我添加到您的答案中的唯一一项是使用“HttpUtility.urldecodrawsresponse”删除“rawsresponse”字符串上的所有HTML代码。如果允许的话，我会在8小时内给你50分的赏金。再次感谢你！这里正在处理的是响应字符串，而不是请求，因此您将无法使用request.QueryString检索详细信息。
