我正在asp.NET中为Web门户构建MVC应用程序.我准备了一系列控制器,并将所有不与之相关的路径映射到Page控制器,这将呈现适当的页面.
我的默认路由如下：
routes.MapRoute(
"Default","{level1}/{level2}/{level3}",new { controller = "Page",action = "Index",level1 = "home",level2 = "",level3 = "" }
);
但这有固定的宽度,它只接受最多3个级别.此外,我想管理附加到路径的操作,如“编辑”和“删除”.这可能吗？
company/about/who_we_are/staff -> Controller: Page,Action: Index,Parms: company/about/who_we_are/staff company/about/who_we_are/staff/edit -> Controller: Page,Action: Edit,Parms: company/about/who_we_are/staff company/edit -> Controller: Page,Parms: company
解决方法
您可以使用通配符路由：
"{*data}"
看看这个SO：ASP.net MVC custom route handler/constraint
简单的解决方案：
(未经测试但……)
路线：
routes.Add(new Route
(
"{*data}",new RouteValueDictionary(new {controller = "Page",data = ""}),new PageRouteHandler()
)
);
处理程序看起来像：
public class PageRouteHandler : IRouteHandler
{
public IHttpHandler GetHttpHandler(RequestContext requestContext)
{
return new PageHttpHandler(requestContext);
}
}
class PageHttpHandler : MvcHandler
{
public PageHttpHandler(RequestContext requestContext)
: base(requestContext)
{
}
protected override void ProcessRequest(HttpContextBase httpContext)
{
IController controller = new PageController();
((Controller)controller).ActionInvoker = new PageActionInvoker();
controller.Execute(RequestContext);
}
}
class PageActionInvoker : ControllerActionInvoker
{
protected override ActionResult InvokeActionMethod(ControllerContext controllerContext,ActionDescriptor actionDescriptor,IDictionary<string,object> parameters)
{
string data = controllerContext.RouteData.GetrequiredString("data");
string[] tokens = data.Split('/');
int lenght = tokens.Length;
if (lenght == 0)
return new NotFoundResult();
if (tokens[tokens.Length - 1] == "edit")
{
parameters["action"] = "edit";
lenght--;
}
for (int i = 0; i < length; i++)
parameters["level" + (i + 1).ToString()] = tokens[i];
return base.InvokeActionMethod(controllerContext,actionDescriptor,parameters);
}
}
