mvc6未经授权导致重定向

Question

当我从Controller返回NotAuthorized IActionResult时,我一直在尝试阻止重定向,但无论我的尝试如何,NotAuthorized都会转换为Redirect.

我已经尝试了这里提到的(同样的问题,使用旧的beta框架,我使用1.0.0-rc1-final).我没有Notifications命名空间(已在rc1-final中删除).

这是我的登录控制器:

    [HttpPost]
    [AllowAnonymous]
    public async Task<IActionResult> Login(LoginViewModel model, string returnUrl = null)
    {
        if (ModelState.IsValid)
        {
            var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, lockoutOnFailure: false);
            if (result.Succeeded)
            {
                return Ok(model);
            }
            if (result.IsLockedOut)
            {
                return new HttpStatusCodeResult((int)HttpStatusCode.Forbidden);
            }
            else
            {
                return HttpUnauthorized();
            }
        }
        return HttpUnauthorized();
    }

在Startup.cs中,我尝试了以下变体:

        services.Configure<CookieAuthenticationOptions>(o =>
        {
            o.LoginPath = PathString.Empty;
            o.ReturnUrlParameter = PathString.Empty;
            o.AutomaticChallenge = false;
        });

每次登录失败时(请忽略密码在Ok上返回)并且应该导致空的401页面,我将重定向到/ Account/Login.这里的诀窍是什么？

解决方案不是直接配置CookieAuthenticationOptions,而是通过IdentityOptions这样做:

        services.Configure<IdentityOptions>(o =>
        {
            o.Cookies.ApplicationCookie.Events = new CookieAuthenticationEvents()
            {
                OnRedirectToLogin = ctx =>
                {
                    if (ctx.Response.StatusCode == (int)HttpStatusCode.Unauthorized)
                    {
                        return Task.FromResult<object>(null);
                    }
                    ctx.Response.Redirect(ctx.RedirectUri);
                    return Task.FromResult<object>(null);
                }
            };
        });

摘自此处(Shawn Wildermuth - > ASP.NET 5身份和REST API - >"Mehdi Hanafi"的评论)并使用Postman测试API

config.Cookies.ApplicationCookie.Events = new CookieAuthenticationEvents()
{
    OnRedirectToLogin = ctx =>
    {
        if (ctx.Request.Path.StartsWithSegments("/api") &&
        ctx.Response.StatusCode == 200)
        {
            ctx.Response.StatusCode = (int)HttpStatusCode.Unauthorized;
            return Task.FromResult<object>(null);
        }
        else
        {
            ctx.Response.Redirect(ctx.RedirectUri);
            return Task.FromResult<object>(null);
        }
    }
};
