MVC JsonResult驼峰系列化

问题描述：

我试图让我的动作返回一个JsonResult，其中所有的属性都在驼峰。

I am trying to make my action return a JsonResult where all its properties are in camelCase.

我有一个简单的模型：

public class MyModel
{
    public int SomeInteger { get; set; }

    public string SomeString { get; set; }
}

和一个简单的控制器动作：

And a simple controller action:

public JsonResult Index()
    {
        MyModel model = new MyModel();
        model.SomeInteger = 1;
        model.SomeString = "SomeString";

        return Json(model, JsonRequestBehavior.AllowGet);
    }

调用这个动作方法现在返回一个包含下列数据的JsonResult：

Calling this action method now returns a JsonResult containing the following data:

{"SomeInteger":1,"SomeString":"SomeString"}

有关我的应用我需要的行动驼峰返回数据，在某种程度上是这样的：

For my uses i need the action return the data in camelCase, somehow like this:

{"someInteger":1,"someString":"SomeString"}

有没有优雅的方式来做到这一点？

Is there any elegant way to do this?

我正在研究在这里可能的解决方案，并发现MVC3 JSON序列化：如何控制属性名称在那里设置数据成员定义到模型的每一个属性，但我真的不希望这样做？

I was looking into possible solutions around here and found MVC3 JSON Serialization: How to control the property names? where they set DataMember definitions to every property of the model, but I do not really want to do this.

此外，我发现，他们说，这是可能的解决正是这种问题的一个链接：http://www.asp.net/web-api/overview/formats-and-model-binding/json-and-xml-serialization#json_camelcasing.它说：

Also I found a link where they say that it is possible to solve exactly this kind of issue: http://www.asp.net/web-api/overview/formats-and-model-binding/json-and-xml-serialization#json_camelcasing. It says:

要写入骆驼外壳JSON属性的名称，而不改变你的数据模型，设置串行的CamelCasePropertyNamesContractResolver：

var json = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();

在这个博客上http://frankapi.word$p$pss.com/2012/09/09/going-camelcase-in-asp-net-mvc-web-api/也mentiones这个解决方案，并指出你可以简单地把它添加到 RouteConfig.RegisterRoutes 以解决此问题。我试了一下，但我不能使它工作。

One entry on this blog http://frankapi.wordpress.com/2012/09/09/going-camelcase-in-asp-net-mvc-web-api/ also mentiones this solution and states you can simply add it to the RouteConfig.RegisterRoutes to fix this issue. I tried it, but I couldn't make it work.

难道你们有什么想法，我是做错了什么？

Do you guys have any idea where I was doing something wrong?

答

控制器的JSON函数只是包装器创建JsonResults：

The Json functions of the Controller are just wrappers for creating JsonResults:

protected internal JsonResult Json(object data)
{
    return Json(data, null /* contentType */, null /* contentEncoding */, JsonRequestBehavior.DenyGet);
}

protected internal JsonResult Json(object data, string contentType)
{
    return Json(data, contentType, null /* contentEncoding */, JsonRequestBehavior.DenyGet);
}

protected internal virtual JsonResult Json(object data, string contentType, Encoding contentEncoding)
{
    return Json(data, contentType, contentEncoding, JsonRequestBehavior.DenyGet);
}

protected internal JsonResult Json(object data, JsonRequestBehavior behavior)
{
    return Json(data, null /* contentType */, null /* contentEncoding */, behavior);
}

protected internal JsonResult Json(object data, string contentType, JsonRequestBehavior behavior)
{
    return Json(data, contentType, null /* contentEncoding */, behavior);
}

protected internal virtual JsonResult Json(object data, string contentType, Encoding contentEncoding, JsonRequestBehavior behavior)
{
    return new JsonResult
    {
        Data = data,
        ContentType = contentType,
        ContentEncoding = contentEncoding,
        JsonRequestBehavior = behavior
    };
}

JsonResult内部使用的JavaScriptSerializer，所以你不要有关于序列化进程控制：

JsonResult internally uses JavaScriptSerializer, so you don't have control about the serialisation process:

public class JsonResult : ActionResult
{
    public JsonResult()
    {
        JsonRequestBehavior = JsonRequestBehavior.DenyGet;
    }

    public Encoding ContentEncoding { get; set; }

    public string ContentType { get; set; }

    public object Data { get; set; }

    public JsonRequestBehavior JsonRequestBehavior { get; set; }

    /// <summary>
    /// When set MaxJsonLength passed to the JavaScriptSerializer.
    /// </summary>
    public int? MaxJsonLength { get; set; }

    /// <summary>
    /// When set RecursionLimit passed to the JavaScriptSerializer.
    /// </summary>
    public int? RecursionLimit { get; set; }

    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null)
        {
            throw new ArgumentNullException("context");
        }
        if (JsonRequestBehavior == JsonRequestBehavior.DenyGet &&
            String.Equals(context.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase))
        {
            throw new InvalidOperationException(MvcResources.JsonRequest_GetNotAllowed);
        }

        HttpResponseBase response = context.HttpContext.Response;

        if (!String.IsNullOrEmpty(ContentType))
        {
            response.ContentType = ContentType;
        }
        else
        {
            response.ContentType = "application/json";
        }
        if (ContentEncoding != null)
        {
            response.ContentEncoding = ContentEncoding;
        }
        if (Data != null)
        {
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            if (MaxJsonLength.HasValue)
            {
                serializer.MaxJsonLength = MaxJsonLength.Value;
            }
            if (RecursionLimit.HasValue)
            {
                serializer.RecursionLimit = RecursionLimit.Value;
            }
            response.Write(serializer.Serialize(Data));
        }
    }
}

您必须创建自己的JsonResult，写自己的Json控制器功能（如果你需要/想这一点）。您可以创建新的或改写现有的，它是由你。这链接也可能会感兴趣。

You have to create your own JsonResult and write your own Json Controller functions (if you need / want that). You can create new ones or overwrite existing ones, it is up to you. This link might also interest you.
