Question

如何在返回到客户端之前编辑和更改ASP.NET Web API返回的JSON。例如：

    public HttpResponseMessage GetCustomerById(int customerId)
    {
        Customer customer = DAL.GetCustomer(123);

        if (customer == null)
        {
            return Request.CreateResponse(HttpStatusCode.NotFound, "Could not find                                        customer " + customerId.ToString());
        }
        else
        {
            return Request.CreateResponse(HttpStatusCode.OK, customer);
             **//  Here I like to edit the JSON before I return it**
        }
    }

您需要使用例如JsonExSerializer库将JSON反序列化为某种对象。然后，您可以开始修改对象，将其序列化为JSON并发送修改后的JSON字符串。使用JsExSer的示例。

Serializer ser = new Serializer(typeof(ArrayList));
ArrayList json = ser.Deserialize(jsonstring);
json.Add("something");
string jsonready = ser.Serialize(json);

另请注意，必须在返回之前进行修改，如下：

**//  Here I like to edit the JSON before I return it**
return Request.CreateResponse(HttpStatusCode.OK, customer);

在ASP.Net Web API中自定义JSON返回的数据
