找不到WebApi控制器 [英] WebApi controller isn't found

问题描述

我的WebApi项目中有一个示例控制器:

I have an example controller in my WebApi-project:

public class MilestonesController : ApiController
{
    // GET api/milestones
    public IEnumerable<string> Get()
    {
        return new string[] { "M#1", "M#2" };
    }

    // GET api/milestones/5
    public string Get(int id)
    {
        return "M with {id}";
    }

    // POST api/milestones
    public void Post([FromBody]string value)
    {
    }

    // PUT api/milestones/5
    public void Put(int id, [FromBody]string value)
    {
    }

    // DELETE api/milestones/5
    public void Delete(int id)
    {
    }
}

如果我尝试导航到它:

http://localhost:59493/api/milestones

我总是会收到错误:

No HTTP resource was found that matches the request URI 'http://localhost:59493/api/milestones'.

No type was found that matches the controller named 'milestones'.

提前谢谢！

我的WebApiConfig:

my WebApiConfig:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        // Web API routes
        config.MapHttpAttributeRoutes();

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

Global.asax:

Global.asax:

public class WebApiApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        GlobalConfiguration.Configure(WebApiConfig.Register);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        WebApiConfig.Register(GlobalConfiguration.Configuration);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
    }
}

可能的解决方案:

我已经删除了我的项目，并且创建了一个新项目(WebAPi项目)，现在它可以工作了.WebApiConfig等是相同的，所以我真的不知道第一次尝试出了什么问题

I have deleted my project and I've created a new one (WebAPi project) and now it works. The WebApiConfig etc was the same, so I don't really know what was wrong with my first try

推荐答案

看看您在哪里创建了该控制器.也许它不在Controllers文件夹中，不在其他名称空间中，或者该控制器类嵌套在另一个类中

Take a look at where you created that controller. Maybe it is not in the Controllers folder, different namespace or that controller class is nested into another class
