c# - 如何在 core2.2 mvc 项目中使用 IClaimsTransformation

问题描述

我正在尝试学习如何IClaimsTransformation在 Windows 身份验证中使用来修改用户声明。但是当我尝试使用它时，我收到一条错误消息

“InvalidOperationException：没有指定 authenticationScheme，也没有找到 DefaultChallengeScheme。”

我主要在mac上尝试它，但我也在公司域的公司电脑上尝试过。他们都给了我同样的错误。我也是 IIS express（来自 VS 和 Rider 的调试模式）。

在我的启动文件中

public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<CookiePolicyOptions>(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });

        services.AddAuthentication(IISDefaults.AuthenticationScheme);
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

        services.AddSingleton<IClaimsTransformation, UserClaims>();

    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }

        app.UseHttpsRedirection();
        app.UseStaticFiles();
        app.UseCookiePolicy();
        app.UseAuthentication();
        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });



    }

我有这个课程用于索赔转换

public class UserClaims: IClaimsTransformation
{
    public Task<ClaimsPrincipal> TransformAsync(ClaimsPrincipal principal)
    {
        var ci = (ClaimsIdentity) principal.Identity;
        var c = new Claim(ci.RoleClaimType, "Admin");
        ci.AddClaim(c);
        return Task.FromResult(principal);
    }
}

也为我的控制器使用这个装饰器

[Authorize(Roles = "Admin")]
