javascript - 在 C# 中反序列化 Paypal 响应的正确方法

Question

简介

我正在为我的演示项目使用 paypal 支付实现。当用户确认请求时，响应和请求以 json 格式收到(正如你们大多数人所知)。

代码设置

Action 数据被“解析”的地方

string str = JObject.Parse(executedPayment.ConvertToJson()).ToString(Newtonsoft.Json.Formatting.Indented);
var payerInfo = new JavaScriptSerializer().Deserialize<ResponseMappingObject.Payer_Info>(str);

foreach(var item in payerInfo)
{
string abc = payerInfo.first_name;
string abc2 = payerInfo.last_name;
}

我为了舒适而添加的映射类

public class Payer_Info
        {
            public string email { get; set; }
            public string first_name { get; set; }
            public string last_name { get; set; }
            public string payer_id { get; set; }
        }

问题

正常情况下，“string str”中的数据接收和解析成功，反序列化也成功。但是构建时出错

foreach statement cannot operate on variables of type 'ResponseMappingObject.Payer_Info' because ResponseMappingObject.Payer_Info' does not contain a public definition for 'GetEnumerator'

问题

如果反序列化 json 响应的方式正确，如何解决这个问题？

如果安全的话，我们可以在 javascript 中反序列化吗？

API 为您提供 c# object ( code source )，使用它的属性，没有什么可以反序列化。你不需要再次转换成 JSON，JSON.parse，序列化，反序列化。例如:

var firstName = executedPayment.payer.payer_info.first_name;
var lastName = executedPayment.payer.payer_info.last_name;

Intellisense 将非常有助于“发现”您需要的所有属性。
