ASP.NET MVC 6上每个控制器的特定JSON设置

我需要在ASP.NET MVC 6 webApi中为每个控制器设置特定的JSON设置。 我发现这个样本（我希望！）适用于MVC 5： 在每个控制器的ASP.NET WebAPI上强制使用CamelCase

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().Single(); controllerSettings.Formatters.Remove(formatter); formatter = new JsonMediaTypeFormatter { SerializerSettings = {ContractResolver = new CamelCasePropertyNamesContractResolver()} }; controllerSettings.Formatters.Add(formatter); } } 

Answer 1

您可以在控制器操作方法上使用返回类型的JsonResult。 在我的情况下，我需要特定的操作来返回某些遗留场景的Pascal Case。 JsonResult对象允许您传递可选参数作为JsonSerializerSettings。

 public JsonResult Get(string id) { var data = _service.getData(id); return Json(data, new JsonSerializerSettings { ContractResolver = new DefaultContractResolver() }); } 

为了获得更一致的控制器方法签名，我最终创建了一个扩展方法：

 public static JsonResult ToPascalCase(this Controller controller, object model) { return controller.Json(model, new JsonSerializerSettings { ContractResolver = new DefaultContractResolver() }); } 

现在我可以简单地在我的控制器中调用扩展方法，如下所示：

 public IActionResult Get(string id) { var data = _service.getData(id); return this.ToPascalCase(data); }

这个类很好用：

 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 {
