使用 IHttpContextAccessor 时尚未为此应用程序或请求配置会话错误

Question

我在 .NET 6 Core 中创建了一个自定义授权策略。它可以很好地满足我的要求，但是我在调​​试时发现了一个错误-尚未为此应用程序或请求配置会话。但我已经在我的 program.cs 中配置了会话。调试时是否应该显示此错误，是否还有要为会话配置的内容？

授权处理程序：

using Microsoft.AspNetCore.Authorization;

namespace myApp.Security
{
    public class CrudAccessHandler : AuthorizationHandler<AccessRequirement>
    {
        private readonly IHttpContextAccessor httpContextAccessor;

        public CrudAccessHandler(IHttpContextAccessor httpContextAccessor)
        {
            this.httpContextAccessor = httpContextAccessor ?? throw new ArgumentNullException(nameof(httpContextAccessor));
        }
        protected override Task HandleRequirementAsync(AuthorizationHandlerContext context, AccessRequirement requirement)
        {
            string? controllerName = httpContextAccessor.HttpContext?.Request.RouteValues["controller"]?.ToString();

            string? actionName = httpContextAccessor.HttpContext?.Request.RouteValues["action"]?.ToString();

            if (controllerName != null && actionName != null)
            {
                if (context.User.HasClaim(claim => (claim.Type == controllerName && claim.Value == actionName)))
                {
                    context.Succeed(requirement);
                }
            }

            if (controllerName != null && actionName == "Index")
            {
                if (context.User.HasClaim(claim => (claim.Type == controllerName && claim.Value == "Read")))
                {
                    context.Succeed(requirement);
                }
            }

            if (controllerName != null && actionName == "Clone")
            {
                if (context.User.HasClaim(claim => (claim.Type == controllerName && claim.Value == "Create")))
                {
                    context.Succeed(requirement);
                }
            }

            return Task.CompletedTask;
        }
    }
}

// Add services to the container.

builder.Services.AddAuthorization(options =>

});

builder.Services.AddTransient<IAuthorizationHandler, SuperAdminHandler>();

builder.Services.AddTransient<IAuthorizationHandler, CrudAccessHandler>();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.UseSession();
app.MapControllerRoute(name: "default", pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

Answer 1

我通过如下更改 HTTP 请求管道顺序解决了我的问题：

app.UseRouting();
app.UseSession();

app.UseAuthentication();
app.UseAuthorization();

这解决了我的 .NET 6 Core 问题
