ASP.. NET MVC 5 - JSON -(动态?)模型绑定- REST服务- Webhooks - Charge

这应该很容易，但我卡住了。我已经建立了一个webhook的服务(ChargeBee)，是成功发布我的网站JSON。这是我试图绑定的模型:

public class ChargeBeeWebhookModel
{
    public string id { get; set; }
    public string occurred_at { get; set; }
    public string source { get; set; }
    public string @object { get; set; }        
    public string content { get; set; }
    public string event_type { get; set; }
    public string webhook_status { get; set; }
}

所有内容都是绑定的，除了"content"，它是空的。问题在于"内容"将根据触发的事件类型而改变。例如，对于"customer created"事件:

 "customer": {
        "id": "8avVGOkx8U1MX",
        "first_name": "Benjamin",
        "last_name": "Ross",
        "email": "Benjamin@test.com",
        "auto_collection": "on",
        "created_at": 1317407411,
        "object": "customer",
        "card_status": "valid",
        "payment_method": {
            "object": "payment_method",
            "type": "card",
            "gateway": "chargebee",
            "reference_id": "tok_KyVr8xPHl5BSx1",
            "status": "valid"
        },
        "account_credits": 0
    },
    "card": {
        "customer_id": "8avVGOkx8U1MX",
        "status": "valid",
        "gateway": "chargebee",
        "iin": "411111",
        "last4": "1111",
        "card_type": "visa",
        "expiry_month": 1,
        "expiry_year": 2016,
        "object": "card",
        "masked_number": "************1111"
    }

我只需要将这些复杂对象绑定到某种类型。绳子坏了。一旦它被绑定，我就可以很容易地检查它是否是我想要使用event_type属性处理的事件，并将其反序列化为适当的自定义类型。

我该怎么做?我觉得我错过了一些很简单的东西。据我所知，Chargebee不会让我为每种类型的事件使用不同的URL，这是我认为最有意义的。这是一个URL，我必须绑定许多可能的响应。

我需要一个自定义模型绑定器或其他东西吗?有更简单的方法吗?

也许有人可以做一个ChargeBee标签?

谢谢每一个人。

按照请求，这是示例请求的样子:

            }],

        },
        "customer": {
            "id": "3Nl8ERLPElBCGl1",
            "first_name": "Benjamin",
            "last_name": "Ross",
            "email": "Benjamin@test.com",
            "auto_collection": "on",
            "created_at": 1341167305,

            "card_status": "valid",
            "payment_method": {
                "object": "payment_method",
                "type": "card",
                "reference_id": "3Nl8ERLPElBCGl1",
                "status": "valid"
            }
        }
    },
    "event_type": "subscription_created",
    "webhook_status": "not_configured"
}

除非我弄错了，我只是认为模型绑定器不能处理这种情况。它需要预定义的类型，不能处理可变性或动态的东西，据我所知。如果我说错了，请纠正我。无论如何，稍后我将用一个完整的代码示例回答这个问题，但现在我已经抛弃了纯模型绑定方法，正在阅读Request。InputStream获取我需要的JSON数据。然后，根据event_type(模型绑定器没有问题)，我将其反序列化为预定义类型。只是我从来没有真正需要手动从请求中选择一些东西;我一直使用模型绑定器

    [HttpPost]
    [BasicAuthentication(username: "x", password: "y", BasicRealm = "z")]
    public HttpStatusCodeResult ChargeBeeWebhook()
    {
        if (ModelState.IsValid)
        {          
            Event chargeBeeEvent = new Event(Request.InputStream);
            EventTypeEnum? eventType = chargeBeeEvent.EventType;
            Event.EventContent eventContent = chargeBeeEvent.Content;
            if (eventType == EventTypeEnum.SubscriptionCreated)
            {
                Subscription subscription = eventContent.Subscription;
                Customer customer = eventContent.Customer;
                // more stuff
            }          
            return new HttpStatusCodeResult(200);
        }
        else
        {
            return new HttpStatusCodeResult(400); // bad request
        }
    }
