如何设置身份服务器重定向URL？

Question

我在.net core 3.1中创建了身份服务器，并且在launchSettings中编写了

{
  "iisSettings": {
    "windowsAuthentication": false, 
    "anonymousAuthentication": true, 
    "iisExpress": {
      "applicationUrl": "http://localhost:50587",
      "sslPort": 44360
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "MyProject.IdentServer": {
      "commandName": "Project",
      "launchBrowser": true,
      "applicationUrl": "https://localhost:5001;http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

我在.net Core 2.2中有一个客户端应用程序，在ConfigureServices方法中的startup.cs文件中，我称为ConfigureIdentityServer（services）;

        private void ConfigureIdentityServer(IServiceCollection services)
        {
            var builder = services.AddAuthentication(options => SetAuthenticationOptions(options));

            builder.AddCookie();
            builder.AddOpenIdConnect(options => SetOpenIdConnectOptions(options));
        }

        private void SetOpenIdConnectOptions(OpenIdConnectOptions options)
        {
            options.Authority = "https://localhost:44360";
            options.ClientId = "MyProject.IdentServer";
            //options.ClientId = "mvc";
            options.ClientSecret = "secret";
            options.ResponseType = "code id_token";
            options.SaveTokens = true;
            options.GetClaimsFromUserInfoEndpoint = true;
            options.RequireHttpsMetadata = false;
            options.Scope.Add("openid");
            options.Scope.Add("profile");
            options.Scope.Add("offline_access");
            options.TokenValidationParameters = new TokenValidationParameters()
            {
                NameClaimType = "name",
                RoleClaimType = "role"
            };


        }

        private void SetAuthenticationOptions(AuthenticationOptions options)
        {
            options.DefaultScheme = Microsoft.AspNetCore.Authentication.Cookies.CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = Microsoft.AspNetCore.Authentication.OpenIdConnect.OpenIdConnectDefaults.AuthenticationScheme;
        }

在用于重定向的客户端控制器操作中，我写了

return Challenge(new AuthenticationProperties() { RedirectUri = "Home/Index" },
             Microsoft.AspNetCore.Authentication.OpenIdConnect.OpenIdConnectDefaults.AuthenticationScheme);

如何以及在何处提供客户端重定向URL，以重定向到身份服务器？
