我有简单的MyRouter:
public class MyRouter : IRouter
{
private readonly IRouteBuilder _routeBuilder;
public MyRouter(IRouteBuilder routeBuilder)
{
_routeBuilder = routeBuilder;
}
public async Task RouteAsync(RouteContext context)
{
if (ShouldReroute(...))
{
SetNeededPath(context, reroute);
}
await GetDefaultRouter().RouteAsync(context);
}
private bool ShouldReroute(...)
{
return true;
}
public VirtualPathData GetVirtualPath(VirtualPathContext context)
{
return GetDefaultRouter().GetVirtualPath(context);
}
private IRouter GetDefaultRouter()
{
return _routeBuilder.DefaultHandler;
}
private void SetNeededPath(RouteContext context, Reroute reroute)
{
context.RouteData.Values.Clear();
context.RouteData.Values["action"] = "StoreContacts";
context.RouteData.Values["controller"] = "Information";
}
}
如您所见,它将请求的目的地更改为:
[Route("")]
public class InformationController : Controller
{
[Route("StoreContacts")]
public IActionResult StoreContacts()
{
return View();
}
}
Startup.cs中的路由器描述为:
app.UseMvc(routes =>
{
routes.MapRoute(
name: "areas",
template: "{area:exists}/{controller=Home}/{action=Index}");
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
routes.Routes.Add(new MyRouter(routes));
});
因此,在我的大脑中,它应该将所有未映射的请求重定向,例如 mysite.com/unexistingRoute 应该转到InformationController.StoreContacts
,但我只有404。
mysite.com/StoreContacts 也可以通过直接URL访问。
答案 0 :(得分:1)
属性路由将取代常规路由,因此您可以删除属性路由:
public class InformationController : Controller
{
public IActionResult StoreContacts()
{
return View();
}
}
然后通过IRouter将逻辑移到自定义路由。 mysite.com/unexistingRoute
不会映射到Startup.cs中现有的路由模板配置。因此remove属性应该在您的方案中起作用。要映射其他网址,例如mysite.com/OtherAction
,可以编写自定义逻辑,例如:
if (context.HttpContext.Request.Path.Value.StartsWith("/StoreContacts"))
{
context.RouteData.Values["controller"] = "Information";
context.RouteData.Values["action"] = "StoreContacts";
}
