我试图阻止应用重定向到 /Account/Login当用户未登录时，在 asp.net core 2.2 中。
即使我写 LoginPath = new PathString("/api/contests");任何未经授权的请求仍会重定向到 /Account/Login这是我的 Startup.cs:

你好，欢迎来到 StackOverflow 👋
您遇到的行为与您使用 ASP.NET Identity 的事实有关。
当您调用 services.AddIdentity ，在后台注册了一个基于 cookie 的身份验证方案并将其设置为默认质询方案，如代码 here on GitHub 中所示.
即使您自己注册了一个 cookie 身份验证方案并将其设置为默认方案，具体的默认方案 — 如 AuthenticateScheme , ChallengeScheme , SignInScheme ，等等……——优先考虑。 DefaultScheme仅当未设置特定时才由身份验证系统使用。
要回答您的问题，您可以使用帮助方法 services.ConfigureApplicationCookie 将配置设置应用于 ASP.NET 身份 cookie 选项。 ，像这样:
// ===== Add Identity ========
services.AddIdentity<User, IdentityRole>(o =>
{
o.User.RequireUniqueEmail = true;
o.Tokens.EmailConfirmationTokenProvider = "EMAILCONF";
// I want to be able to resend an `Email` confirmation email
// o.SignIn.RequireConfirmedEmail = true;
}).AddRoles<IdentityRole>()
.AddEntityFrameworkStores<ContestContext>()
.AddTokenProvider<EmailConfirmationTokenProvider<User>>("EMAILCONF")
.AddDefaultTokenProviders();
services.Configure<DataProtectionTokenProviderOptions>(o =>
o.TokenLifespan = TimeSpan.FromHours(3)
);
services.Configure<EmailConfirmationTokenProviderOptions>(o =>
o.TokenLifespan = TimeSpan.FromDays(2)
);
// ===== Configure Identity =======
service.ConfigureApplicationCookie(options =>
{
options.Cookie.Name = "auth_cookie";
options.Cookie.SameSite = SameSiteMode.None;
options.LoginPath = new PathString("/api/contests");
options.AccessDeniedPath = new PathString("/api/contests");
// Not creating a new object since ASP.NET Identity has created
// one already and hooked to the OnValidatePrincipal event.
// See https://github.com/aspnet/AspNetCore/blob/5a64688d8e192cacffda9440e8725c1ed41a30cf/src/Identity/src/Identity/IdentityServiceCollectionExtensions.cs#L56
options.Events.OnRedirectToLogin = context =>
{
context.Response.StatusCode = StatusCodes.Status401Unauthorized;
return Task.CompletedTask;
};
});
这也意味着您可以安全地删除添加基于 cookie 的身份验证方案的部分，因为这由 ASP.NET Identity 本身负责。
让我知道你怎样去!
