Question

这是我的Web API项目中路由的Register方法

config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
    name: "AllRoutes",
    routeTemplate: "{*url}",
    defaults: new { controller = "IncomingRequest", action = "ProcessRequest" });

我希望一切都能在我的IncomingRequest控制器上运行我的ProcessRequest方法。但是所有路线都会产生404.例如

http://localhost/CatCatcher/Cat/3

有人可以告诉我可能错过的内容吗？

试试这个：

routes.MapRoute(
"AllRoutes",
 "{*id}",
  new { controller = "IncomingRequest", action = "ProcessRequest", id = "" }
);

对不起，我现在测试了它......

在Web API项目中，您无法通过不同的方式设置路由，如：

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

要实现URL（“http://localhost/CatCatcher/Cat/3”），您可以在控制器和操作上设置路由前缀。以下是示例：

[RoutePrefix("CatCatcher")]
public class CatCatcherController : ApiController
{

    [HttpGet]
    [Route("Cat")]
    public object Cat(int Id){
    //Do something
    }

}

如果你想在点击Action之前继续执行，那么让我们按照我用IP / Domain保护API的例子来说：

public class AuthorizeIPAddressAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(HttpActionContext filterContext)
        {
            //Even you can do here what you want
            //Get users IP Address 
            string ipAddress = HttpContext.Current.Request.UserHostAddress;

            if (!IsIpAddressValid(ipAddress.Trim()))//check allow ip
            {
                //Send back a HTTP Status code of 403 Forbidden  
                filterContext.Response = new HttpResponseMessage(System.Net.HttpStatusCode.NotFound);
            }

            base.OnActionExecuting(filterContext);
        }

在项目中添加此类后，您只需在控制器上执行此操作：

[AuthorizeIPAddress]   
[RoutePrefix("CatCatcher")]
public class CatCatcherController : ApiController
{

    [HttpGet]
    [Route("Cat")]
    public object Cat(int Id){
    //Do something
    }

}

希望这会对你有帮助..

MVC Catch-All路由是唯一定义的路由，但它给了我404
