我正在尝试在ASP.Net MVC Core 2应用程序中为管理员实现Area
。
我已按如下方式为该区域配置路线:
// Default route
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
// Admin area route
app.UseMvc(routes =>
{
routes.MapRoute(
name: "admin",
template: "{area=Admin}/{controller=Home}/{action=Index}/{id?}");
});
这一切都很好。
此管理员area
使用与主网站相同的Layout
,尽管_ViewStart.cshtml
位于Areas/Admin/Views
目录中,但这仍然正常。
我遇到的问题是导航菜单组件位于主站点布局文件中,并且所有锚点中的href
链接指向管理区域内的错误URL。
说我有以下链接:
<a asp-controller="Account" asp-action="Index">My Account</a>
<a asp-controller="Shopping" asp-action="Basket">Shopping Basket</a>
<a asp-controller="Admin" asp-action="Users">Manage Users</a>
当在管理区域内时,链接现在相对于该区域,因此看起来好像如下:
http://localhost/Admin/Account/Index
http://localhost/Admin/Shopping/Basket
http://localhost/Admin/Admin/Users
有没有很好的方法来制作相对于网站根目录的所有这些链接?

您在应用程序中设置的方式有几个问题。
app.UseMvc()
两次。我认为基本上最后一个将覆盖你的第一个设置。这就是为什么您看到所有链接都有/admin
区域前缀。admin
区域下生成指向用户管理的链接,则应使用asp-area
,而不是<a asp-area="admin" asp-controller="users" asp-action="index">Manage Users</a>
。这就是我设置区域的方式。
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
// The area routing setup has to come before your default routing!
// Remember the order of these setups is very important!
// Mvc will use that template as soon as it finds a matching!
app.UseMvc(routes =>
{
routes.MapRoute(
name: "areaRoute",
template: "{area:exists}/{controller=dashboard}/{action=index}/{id?}"
);
routes.MapRoute(
name: "default",
template: "{controller=home}/{action=index}/{id?}"
);
}
// Assume you have an Admin area under /Areas/Admin
namespace DL.SO.Web.UI.Areas.Admin.Controllers
{
[Area("admin")]
public abstract class AdminControllerBase : Controller
{
}
}
// Dashboard controller. I know you have home controller inside
// your admin area but they should work the same.
namespace DL.SO.Web.UI.Areas.Admin.Controllers
{
public class DashboardController : AdminControllerBase
{
public IActionResult Index()
{
return View();
}
}
}
// Users controller. I know you have User(s) controller but I usually
// just keep the name of the controller singular.
namespace DL.SO.Web.UI.Areas.Admin.Controllers
{
public class UserController : AdminControllerBase
{
public IActionResult Index()
{
return View();
}
}
}
// My habit is to always specify the area with the anchor tag helper.
// For public links (those are not under any areas):
// I just pass empty string, like asp-area=""
// For links pointing to any controller under any area:
// Just pass the area, like asp-area="admin"
// http://localhost/account
<a asp-area="" asp-controller="account" asp-action="index">My Account</a>
// http://localhost/shopping/basket
<a asp-area="" asp-controller="shopping" asp-action="basket">Shopping Basket</a>
// http://localhost/admin/user
<a asp-area="admin" asp-controller="user" asp-action="index">Manage Users</a>
// http://localhost/admin/dashboard
<a asp-area="admin" asp-controller="dashboard" asp-action="index">Admin Panel</a>

您可以编辑要显示为首选的URL的模板。即改为
template: "{controller=Home}/{action=Index}/{id?}");
