通过我在我的MVC控制器下面的方法未找到:MVC 5途径,如果参数在URL
[HttpGet]
public ActionResult Add(Guid b)
{
ViewBag.Title="Add Location";
//init some info
return View("Edit",<Model>);
}
[HttpGet]
public ActionResult Edit(Guid l)
{
ViewBag.Title="Edit Location";
//get object from db
return View("Edit",<Model>);
}
以下是路线报名:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
现在,当我尝试访问以下两条路线:
1. http://localhost:60732/Location/Add?b=512f770f-51c3-4791-8eba-61fe753e2a83
2. http://localhost:60732/Location/Edit?l=512f770f-51c3-4791-8eba-61fe753e2a83
第一个作品,但第2给出了404
我也试图与AttributeRouting
以下途径:
[HttpGet]
[Route("Location/AddLocation/{g}")]
public ActionResult Add(Guid g)
[HttpGet]
[Route("Location/EditLocation/{l}")]
public ActionResult Edit(Guid l)
再次,
http://localhost:60732/Location/AddLocation/512f770f-51c3-4791-8eba-61fe753e2a83
的作品,但
http://localhost:60732/Location/EditLocation/512f770f-51c3-4791-8eba-61fe753e2a83
没有。
我在做什么错?
奇怪的是,如果我通过错Guid
像:
http://localhost:60732/Location/EditLocation/512f770f
它提供了以下错误:
The parameters dictionary contains a null entry for parameter 'l' of non-nullable type
'System.Guid' for method 'System.Web.Mvc.ActionResult Edit(System.Guid)' in
'AppointmentScheduler.Controllers.LocationController'. An optional parameter must be a
reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters
我看到这段代码没有错,它应该工作。我们在这里错过了什么吗? – DavidG
@DavidG这是我无法弄清楚的。这里没有什么特别的东西,但它仍然不起作用。 – TheVillageIdiot
通过编辑,看起来错误来源于操作方法。这是否会抛出404错误或'HttpNotFound'异常? – DavidG
