Asp.net为web-api解雇重定向的核心授权

Question

我尝试使用SPA开始使用asp.net核心Web应用程序.我已经通过教程构建了所有内容.所以我设置了这样的授权:

            app.UseIdentity()
            .UseCookieAuthentication(new CookieAuthenticationOptions()
            {
                AuthenticationScheme = "MyCookieMiddlewareInstance",
                AutomaticAuthenticate = true,
                AutomaticChallenge = true
            });

我有web-api控制器:

[Route("Somewhere")]
[Produces("application/json")]
[Authorize()]
public class MyControllerController : Controller
{
    [HttpGet]
    public async Task<IEnumerable<Something>> GetSomething()
    {
       //....
    }
}

和授权功能:

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> Login(LoginViewModel model)
    {
        //...
        var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe);
        if (result.Succeeded)
        {
            _logger.LogInformation(1, "User logged in.");
            return Redirect("somewhere");
        }
        //...
    }

但是当我在JS中调用我的webapi端点时,我会收到重定向到登录页面而不是401状态.

我已经开始进行调查,发现在计算器的答案,我要设置false到AutomaticChallenge并删除.UseIdentity().但是当我这样做时,我的[POST]AccountController.Login方法停止在线工作 - var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe);例外 - No authentication handler is configured to handle the scheme: Identity.Application.

我想在我的MVC控制器中接收重定向,但是在没有授权的情况下从Webapi端点接收401/403.如何实现AuthorizeAttributeMVC和WebApi控制器的不同行为？谢谢你的任何进步.

MichałDymel写了一篇关于这篇文章的博文:https://devblog.dymel.pl/2016/07/07/return-401-unauthorized-from-asp-net-core-api/

而不是设置AutomaticChallenge为false,他使用IdentityOptions截取重定向到登录视图,并在请求URL以"/ api /"段开头时拒绝它.要实现此目的,您应该Startup.ConfigureServices按如下方式修改方法:

services.AddIdentity<User, Role>(identityOptions =>
    {
        identityOptions.Cookies.ApplicationCookie.Events =
            new CookieAuthenticationEvents
            {
                OnRedirectToLogin = context =>
                                    {
                                        if (context.Request.Path.StartsWithSegments("/api") &&
                                            context.Response.StatusCode == (int) HttpStatusCode.OK)
                                            context.Response.StatusCode = (int) HttpStatusCode.Unauthorized;
                                        else
                                            context.Response.Redirect(context.RedirectUri);

                                        return Task.CompletedTask;
                                    }
            };
    });
