Question

问题背景：

更新

我仍然不确定如何从此回复中提取相关信息。我已经尝试将我的响应类型设置为JSON但仍然收到响应，如下所示。我已经考虑了有关使用NameValueCollection的内容，但仍然无法看到这对如此大的响应有何帮助。理想情况下，我希望映射到某种对象结构，它必然必须是JSON。

问题：

我目前正在使用PayPal Api＆＃39; ExpressCheckout＆＃39;允许用户为我的测试网站上的项目付费的方法。来自API的HTTP响应提供了大量响应，其中包含我需要提取的关键信息 - 例如买方地址，付款是否成功等等。

问题：

目前我一直坚持如何使用响应。理想情况下，我将数据转换为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很棒的C＃对象。

Answer 1

您是否有任何特定原因需要JSON格式？如果它不是必需的，并且你可以使用键值对，那么这里可以将响应作为键值对处理。

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;
    }
}

Answer 2

仍然不确定以NameValueCollection 处理它是什么问题。

E.g。

//NameValueCollection 
//or use  HttpUtility.ParseQueryString(some_string_of_names_values)
var foo = Request.QueryString; 

var bar = foo["FIRSTNAME"]; //based on above this is "Joe"

更新

这是正在处理的响应字符串而不是请求因此您无法使用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

将大型httpresponse流转换为JSON字符串？
