Question

我在global.asax中定义了默认路由

    routes.MapRoute(
        "Default", // Route name
        "{controller}/{action}/{id}", // URL with parameters
        new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
    );

我需要实现这一点。

/somecontroller/edit/1 - 当id是一个数字时，就放手吧 /somecontroller/edit/xxxx - 当id为字符串时，将其重定向到/somecontroller/xxxx

仅在调用动作时才编辑。

Answer 1

可能你不能只通过路线处理它。您需要在Edit操作中进行检查，并在字符串值的情况下重定向到Index操作，否则请处理编辑操作。

路由约束

public class IsIntegerConstraint : IRouteConstraint
{
    #region IRouteConstraint Members

    public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
    {
        int result;

        return int.TryParse(values[parameterName].ToString(), out result);
    }

    #endregion
}

<强>路由

routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults
            new { id = new IsIntegerConstraint() }
        );

在RegisterRoutes方法中，url被转换为控制器，动作和其他参数的名称和值您可以编写自己的地图路线逻辑 - 将继续执行满足的第一行。

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

// empty url is mapping to Home/Index
routes.MapRoute(null, "", new { controller = "Home", action = "Index", id = UrlParameter.Optional });

// accepts "Whatever/Edit/number", where Whatever is controller name (ie Home/Edit/123)
routes.MapRoute(null,
      // first is controller name, then text "edit" and then parameter named id
      "{controller}/edit/{id}", 
      // we have to set action manually - it isn't set in url - {action} not set
      new { action = "edit"},  
      new { id = @"\d+" }      // id can be only from digits
    );


// action name is AFTER edit (ie Home/Edit/MyActionMethod)
routes.MapRoute(null, "{controller}/edit/{action}");

// default action is index -> /Home will map to Home/Index
routes.MapRoute(null, "{controller}", new{action="Index"}); 

// accepts controller/action (Home/Index or Home/Edit)
routes.MapRoute(null, "{controller}/{action}");                 

// controller_name/action_name/whatever, where whatever is action method's id parameter (could be string)
routes.MapRoute(null, "{controller}/{action}/{id}");

按路线值重定向路线
