ASP.NET MVC 6上每个控制器的特定JSON设置

问题描述

在ASP.NET MVC 6 webApi中，每个控制器都需要特定的JSON设置.我发现此示例对MVC 5有效(希望！):在每个控制器的ASP.NET WebAPI上强制使用CamelCase

I need specific JSON settings per controller in my ASP.NET MVC 6 webApi.I found this sample that works (I hope !) for MVC 5 :Force CamelCase on ASP.NET WebAPI Per Controller

using System;
using System.Linq;
using System.Web.Http.Controllers;
using System.Net.Http.Formatting;
using Newtonsoft.Json.Serialization;

public class CamelCaseControllerConfigAttribute : Attribute, IControllerConfiguration
{
    public void Initialize(HttpControllerSettings controllerSettings, HttpControllerDescriptor controllerDescriptor)
    {
        var formatter = controllerSettings.Formatters.OfType<JsonMediaTypeFormatter>().Single();
        controllerSettings.Formatters.Remove(formatter);

        formatter = new JsonMediaTypeFormatter
        {
            SerializerSettings = {ContractResolver = new CamelCasePropertyNamesContractResolver()}
        };

        controllerSettings.Formatters.Add(formatter);

    }
}

推荐答案

此类正常工作:

using System;
using System.Linq;
using Newtonsoft.Json.Serialization;
using Microsoft.AspNet.Mvc.Filters;
using Newtonsoft.Json;
using Microsoft.AspNet.Mvc.Formatters;

namespace Teedl.Web.Infrastructure
{
    [AttributeUsage(AttributeTargets.Class, AllowMultiple = false, Inherited = true)]

    public class MobileControllerConfiguratorAttribute : Attribute, IResourceFilter
    {
        private readonly JsonSerializerSettings serializerSettings;

        public MobileControllerConfiguratorAttribute()
        {
            serializerSettings = new JsonSerializerSettings()
            {
                ContractResolver = new CamelCasePropertyNamesContractResolver(),
                TypeNameHandling = Newtonsoft.Json.TypeNameHandling.Objects,
                TypeNameAssemblyFormat = System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Simple,
                Binder = new TypeNameSerializationBinder("Teedl.Model.Mobile.{0}, Teedl.Model.ClientMobile")
        };
        }


        public void OnResourceExecuted(ResourceExecutedContext context)
        {
        }

        public void OnResourceExecuting(ResourceExecutingContext context)
        {
            var mobileInputFormatter = new JsonInputFormatter(serializerSettings);
            var inputFormatter = context.InputFormatters.FirstOrDefault(frmtr => frmtr is JsonInputFormatter);
            if (inputFormatter != null)
            {
                context.InputFormatters.Remove(inputFormatter);
            }
            context.InputFormatters.Add(mobileInputFormatter);

            var mobileOutputFormatter = new JsonOutputFormatter(serializerSettings);
            var outputFormatter = context.OutputFormatters.FirstOrDefault(frmtr => frmtr is JsonOutputFormatter);
            if (outputFormatter != null)
            {
                context.OutputFormatters.Remove(outputFormatter);
            }
            context.OutputFormatters.Add(mobileOutputFormatter);
        }
    }
}

使用:

[Route("api/mobile/businessrequest")]
[Authorize]
[MobileControllerConfigurator]
public class MobileBusinessRequestController : BaseController
{
