Ответ 1
Благодаря всем ссылкам на другие страницы Stackoverflow, я собираюсь опубликовать три решения, чтобы любой другой, имеющий подобную проблему, мог выбрать свой код. Первый пример кода - это тот, который я создал после просмотра того, что делали другие люди. Последние два из других пользователей Stackoverflow. Надеюсь, это поможет кому-то еще!
// Solution #1 - This is my solution. It updates the JsonMediaTypeFormatter whenever a response is sent to the API call.
// If you ever need to keep the controller methods untouched, this could be a solution for you.
using System;
using System.Net;
using System.Net.Http;
using System.Net.Http.Formatting;
using System.Web.Http;
using Newtonsoft.Json.Serialization;
public class CamelCasedApiController : ApiController
{
public HttpResponseMessage CreateResponse(object responseMessageContent)
{
try
{
var httpResponseMessage = Request.CreateResponse(HttpStatusCode.OK, responseMessageContent, JsonMediaTypeFormatter.DefaultMediaType);
var objectContent = httpResponseMessage.Content as ObjectContent;
if (objectContent != null)
{
var jsonMediaTypeFormatter = new JsonMediaTypeFormatter
{
SerializerSettings =
{
ContractResolver = new CamelCasePropertyNamesContractResolver()
}
};
httpResponseMessage.Content = new ObjectContent(objectContent.ObjectType, objectContent.Value, jsonMediaTypeFormatter);
}
return httpResponseMessage;
}
catch (Exception exception)
{
return Request.CreateResponse(HttpStatusCode.InternalServerError, exception.Message);
}
}
}
Второе решение использует атрибут для украшения метода контроллера API.
// http://stackoverflow.com/questions/14528779/use-camel-case-serialization-only-for-specific-actions
// This code allows the controller method to be decorated to use camel-casing. If you can modify the controller methods, use this approach.
using System.Net.Http;
using System.Net.Http.Formatting;
using System.Web.Http.Filters;
using Newtonsoft.Json.Serialization;
public class CamelCasedApiMethodAttribute : ActionFilterAttribute
{
private static JsonMediaTypeFormatter _camelCasingFormatter = new JsonMediaTypeFormatter();
static CamelCasedApiMethodAttribute()
{
_camelCasingFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
}
public override void OnActionExecuted(HttpActionExecutedContext httpActionExecutedContext)
{
var objectContent = httpActionExecutedContext.Response.Content as ObjectContent;
if (objectContent != null)
{
if (objectContent.Formatter is JsonMediaTypeFormatter)
{
httpActionExecutedContext.Response.Content = new ObjectContent(objectContent.ObjectType, objectContent.Value, _camelCasingFormatter);
}
}
}
}
// Here is an example of how to use it.
[CamelCasedApiMethod]
public HttpResponseMessage Get()
{
...
}
Последнее решение использует атрибут для украшения всего API-контроллера.
// http://stackoverflow.com/questions/19956838/force-camalcase-on-asp-net-webapi-per-controller
// This code allows the entire controller to be decorated to use camel-casing. If you can modify the entire controller, use this approach.
using System;
using System.Linq;
using System.Net.Http.Formatting;
using System.Web.Http.Controllers;
using Newtonsoft.Json.Serialization;
public class CamelCasedApiControllerAttribute : Attribute, IControllerConfiguration
{
public void Initialize(HttpControllerSettings httpControllerSettings, HttpControllerDescriptor httpControllerDescriptor)
{
var jsonMediaTypeFormatter = httpControllerSettings.Formatters.OfType<JsonMediaTypeFormatter>().Single();
httpControllerSettings.Formatters.Remove(jsonMediaTypeFormatter);
jsonMediaTypeFormatter = new JsonMediaTypeFormatter
{
SerializerSettings =
{
ContractResolver = new CamelCasePropertyNamesContractResolver()
}
};
httpControllerSettings.Formatters.Add(jsonMediaTypeFormatter);
}
}
// Here is an example of how to use it.
[CamelCasedApiController]
public class SomeController : ApiController
{
...
}
