Question

我在我的应用程序中使用了MVC和WebApi。为了实现IoC，我使用结构图示例包（StructureMap.WebApi2）

在MVC控制器中一切正常但是当我使用web api时，例如将某些内容发布到服务器上我会收到此错误：

[HttpException]: The controller for path &#39;/api/Activity/AddActivity&#39; was not found or does not implement IController.
   at System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType)
   at System.Web.Mvc.MvcHandler.ProcessRequestInit(HttpContextBase httpContext, IController& controller, IControllerFactory& factory)
   at System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContextBase httpContext, AsyncCallback callback, Object state)
   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step)
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

这是AddActivity行动：

[HttpPost]
[ActionName("AddActivity")]
public HttpResponseMessage AddActivity(ActivityDTO activityDTO)
  {
      ActivityDTO data = activityDTO;
      HttpResponseMessage response = new HttpResponseMessage();

      data.UserID = User.Identity.GetUserId();

      int id = _activityServices.Add(data);

      if (id != -1)
      {
         response = this.Request.CreateResponse(HttpStatusCode.OK, id);
      }
      else
      {
         response=this.Request.CreateErrorResponse(HttpStatusCode.InternalServerError, "Activity doesn't save.");
      }

       return response;
  }

我检查了行动的路径，这是正确的。

你可以帮帮我吗？

感谢

更新1：

WebApiConfig.cs

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {

        var container = IoCFactory.Container;

        GlobalConfiguration.Configuration.Services.Replace(
            typeof(IHttpControllerActivator), new IoCWebApiControllerFactory(container));

        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "ControllerActionApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional }
            );

        config.Routes.MapHttpRoute(
            name: "ControllerApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

AjaxRequest：

$.post("/api/Activity/AddActivity", data)

您的问题不是依赖项注入。在构造函数上放置一个断点，并检查注入的依赖项是否不为null。如果这些不为null，则说明您的设置正确。

您遇到路由问题。使用[ActionName("AddActivity")]时，应该定义如下的路由：

routes.MapHttpRoute(
   name: "ActionApi",
   routeTemplate: "api/{controller}/{action}/{id}",
   defaults: new { id = RouteParameter.Optional } );

web-api的默认routeTemplate没有{action}部分。另外，您不应该在这里使用ActionName，因为it has a different purpose。将其替换为Route属性以使用attribute routing功能。 More info
