如何将所有路由传递给 Web API 中的单个控制器？

Question

我有一个 OWIN 托管应用程序，它可以做 2 件事：

1. 在mydomain.com/api/...提供API

2. 将所有其他请求路由到返回 HTML 页面的单个控制器

我目前有这条路线：

config.Routes.MapHttpRoute(
    name: "default",
    routeTemplate: "{controller}",
    defaults: new { controller = "Index" }
);

还有这个控制器：

public class IndexController : ApiController
{
    public HttpResponseMessage Get()
    {
        string html = File.ReadAllText(@"C:/www/.../index.html");
        HttpResponseMessage response = new HttpResponseMessage
        {
            Content = new StringContent(html),
            StatusCode = System.Net.HttpStatusCode.OK
        };
        response.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html");
        return response;
    }
}

当我去我的家乡路线时，这很好用：

mydomain.com => HTML

如何配置路由模板，以便我总是转到同一个控制器？

mydomain.com/path1 => I want the same HTML
mydomain.com/path1/something => I want the same HTML
mydomain.com/path2 => I want the same HTML
mydomain.com/path3/somethingElse => I want the same HTML
etc

我想要的似乎很简单...我不在乎它是 GET、POST 还是其他。除非路由以api/ 开头，否则我想返回一个 HTML 页面。

有没有使用 Web API 实现此目的的好方法？

=== 编辑

我也在使用静态文件 - 所以静态文件系统的路径应该被明确忽略：

HttpConfiguration config = new HttpConfiguration();
config.MapHttpAttributeRoutes();
config.Routes.IgnoreRoute("StaticFiles", "Public/{*url}");
...

创建单独的路线。一个用于API，另一个用于所有其他路径

//mydomain.com/api/...
config.Routes.MapHttpRoute(
    name: "api",
    routeTemplate: "api/{controller}",
    defaults: new { controller = "Service" }
);


//mydomain.com/path1 => I want the same HTML
//mydomain.com/path1/something => I want the same HTML
//mydomain.com/path2 => I want the same HTML
//mydomain.com/path3/somethingElse => I want the same HTML
config.Routes.MapHttpRoute(
    name: "default-catch-all",
    routeTemplate: "{*url}",
    defaults: new { controller = "Index", action = "Handle" }
);

控制器可以根据需要处理请求。

public class IndexController : ApiController {
    [HttpGet]
    [HttpPost]
    [HttpPut]
    public IHttpActionResult Handle(string url) {
        string html = File.ReadAllText(@"C:/www/.../index.html");
        var response = Request.CreateResponse(System.Net.HttpStatusCode.OK, html, "text/html");
        return ResponseMessage(response);
    }
}
