将JSON.NET格式化程序用于普通控制器

Question

当从控制器(MVC 4 RC)返回Json时,我想修改Json以使用camel-casing作为属性并执行此操作我尝试设置GlobalConfiguration.Formatters.JsonFormatter(不确定这是否正确... don没有代码在我面前),但这似乎不会影响Controller.Json方法输出的Json.

环顾四周之后,这种方法似乎只会影响Web API控制器等.这是真的吗？此外,是否可以更改Controller.Json()方法来实现这一点？

就像@rouen建议的那样,创建了自己的JsonDotNetResult.

这是我项目中的一个:

public class JsonNetResult : ActionResult
{
    public Encoding ContentEncoding { get; set; }
    public string ContentType { get; set; }
    public object Data { get; set; }
    public int StatusCode { get; set; }

    public JsonSerializerSettings SerializerSettings { get; set; }

    public JsonNetResult()
    {
        SerializerSettings = new JsonSerializerSettings
        {
            ContractResolver = new CamelCasePropertyNamesContractResolver()
        };
    }

    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null)
            throw new ArgumentNullException("context");

        var response = context.HttpContext.Response;

        response.StatusCode = StatusCode;
        response.ContentType = string.IsNullOrEmpty(ContentType) ? "application/json" : ContentType;

        if ((StatusCode >= 400) && (StatusCode <= 599))
            response.TrySkipIisCustomErrors = true;

        if (ContentEncoding != null)
            response.ContentEncoding = ContentEncoding;

        if (Data == null)
            return;

        var formatting = Formatting.None;

#if DEBUG
        formatting = Formatting.Indented;
#endif

        var writer = new JsonTextWriter(response.Output) { Formatting = formatting };

        var serializer = JsonSerializer.Create(SerializerSettings);
        serializer.Serialize(writer, Data);

        writer.Flush();
    }
}

然后我有自己的baseController,我继承了给我JsonDotNet(对象viewModel)类型的方法.

例如

protected JsonNetResult JsonNet(object data = null, int statusCode = (int)HttpStatusCode.OK, string contentType = null)
{
    return new JsonNetResult
               {
                   Data = data,
                   StatusCode = statusCode,
                   ContentType = contentType
               };
}

protected JsonNetResult JsonNetForbidden()
{
    return JsonNet(statusCode: (int)HttpStatusCode.Forbidden);
}

protected JsonNetResult JsonNetNotFound()
{
    return JsonNet(statusCode: (int)HttpStatusCode.NotFound);
}

protected JsonNetResult JsonNetNoContent()
{
    return JsonNet(statusCode: (int)HttpStatusCode.NoContent);
}

protected JsonNetResult JsonNetCreated(object data)
{
    return JsonNet(data, (int)HttpStatusCode.Created);
}

protected JsonNetResult JsonNetReload()
{
    return JsonNet(new { reload = true });
}

protected JsonNetResult JsonNetRedirect(string url = null, string contentType = null)
{
    return JsonNet(new { redirectUrl = url }, contentType: contentType);
}

protected JsonNetResult JsonNetClientError(ErrorDictionary errors)
{
    return JsonNet(new { Errors = errors }, (int)HttpStatusCode.BadRequest);
}

protected JsonNetResult JsonNetUnauthorized()
{
    return JsonNet(null, (int)HttpStatusCode.Unauthorized);
}

protected JsonNetResult JsonNetFlashMessage(string message)
{
    return JsonNet(new { flashMessage = message });
}
