问题描述

我看到了许多与我的标题相似的其他问题，但似乎没有一个是我需要的相同问题或提供的见解.

I've seen many other questions that are similar to my title but none seem to be same issue or supply insight that I need.

我已将 Web API 控制器添加到现有的旧版 4.5 WebForms 应用程序中，并尝试在对现有代码库进行最少更改的情况下使其工作.因此，当您从头开始创建项目时，我没有典型的静态 WebApiConfig 类和其他默认创建的项目.我现有的代码库是:

I've added a Web API Controller to an existing, legacy 4.5 WebForms application and am trying to get it working with minimal changes to existing code base. So I don't have the typical static WebApiConfig class and other default created items when you create project from scratch. My existing code base is:

Global.asax

protected void Application_Start( Object sender, EventArgs e )
{
    GlobalConfiguration.Configure( config =>
    {
        config.MapHttpAttributeRoutes();

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

控制器

namespace Modeler.Endpoints
{
    public class KatAppEndpoints : ApiController
    {
        [HttpGet]
        [Route( "api/katapp/calculations" )]
        public IEnumerable<string> GetCalculations()
        {
            return new string[] { "value1", "value2" };
        }
    }
}

Javascript

$(document).ready(function() {
    $.getJSON("api/katapp/calculations")
        .done(function () { debugger; })
        .fail(function (_jqXHR, errorStatus, errorMessage) { debugger; })
        .always(function () { debugger; });
});

调用时，我点击了fail 和always，结果是:

When called, I hit the fail and always and the result is:

错误状态:错误"
错误消息:未找到"

有什么明显我遗漏的地方吗?

Anything obvious I'm missing?

更新

如果相反，我将控制器更改为...

If instead I change my Controller to...

namespace Modeler.Endpoints
{
    public class KatAppsController : ApiController
    {
        public IEnumerable<string> Get()
        {
            return new string[] { "value1", "value2" };
        }
    }
}

我的 javascript 到:

And my javascript to:

$.getJSON("api/katapps")
    .done(function () { debugger; })
    .fail(function (_jqXHR, errorStatus, errorMessage) { debugger; })
    .always(function () { debugger; });

一切正常.但是，我有一些端点并想使用属性，但如果我能弄清楚如何在 url 中获取另一部分(即上面的/calculations 部分)，也许我会放弃它.

Things work correctly. However, I have a handful of endpoints and wanted to use Attributes, but maybe I'll give up on that if I can figure out how to get another portion in the url (i.e. the /calculations part from above).
