c# - 将区域文件夹中的页面设置为asp.net core 2.2 MVC中的默认页面

Question

我想将登录页面设置为默认页面。登录页面存在于区域文件夹中

下面是项目结构

我曾尝试在 Startup.cs 页面中设置默认路由，但无法设置下面是 starup.cs 的快照

 app.UseMvc(routes =>
    {
        routes.MapRoute(
              name: "default",
              template: "identity/{controller=Account}/{action=Signin}");

        routes.MapRoute(
              name: "areaRoute",
              template: "{area:exists}/{controller}/{action}"
            );
    });

每次我收到错误 404 错误无法找到确切的问题所在

Controller 代码:

    [Area("Identity")]
    [Route("identity/[controller]")]
    public class AccountController : BaseController
    {
        private readonly UserManager<ApplicationUser> _userManager;
        private readonly SignInManager<ApplicationUser> _signInManager;


        public AccountController(
         UserManager<ApplicationUser> userManager,
         SignInManager<ApplicationUser> signInManager
         )
        {
            _userManager = userManager;
            _signInManager = signInManager;
        }


        // GET: /Account/SignIn 
        [Route("[action]")]
        [HttpGet]
        [AllowAnonymous]
        public async Task<IActionResult> SignIn(string returnUrl = null)
        {                
            return View();
        }
    }

I want to set Login Page as Default page.Login page is present in Area Folder

最简单的方法是为area、controller和action配置默认值:

    app.UseMvc(routes =>    {        routes.MapRoute(            name: "default",            template: "identity/{controller=Account}/{action=Signin}");        
  
   routes.MapRoute(              name: "areaRoute",              template: "{area:exists}/{controller}/{action}"            );
          routes.MapRoute(            name: "areaRoute",            template: "{area=Identity}/{controller=Account}/{action=Signin}"        );    });

Controller code : Need to Remove Route parameter

    [Area("Identity")]        
    public class AccountController : BaseController
    {
        private readonly UserManager<ApplicationUser> _userManager;
        private readonly SignInManager<ApplicationUser> _signInManager;


        public AccountController(
         UserManager<ApplicationUser> userManager,
         SignInManager<ApplicationUser> signInManager
         )
        {
            _userManager = userManager;
            _signInManager = signInManager;
        }


        // GET: /Account/SignIn            
        [HttpGet]
        [AllowAnonymous]
        public async Task<IActionResult> SignIn(string returnUrl = null)
        {                
            return View();
        }
    }
