asp.net-mvc-4 – 在Startup.Auth.cs之外配置的CookieAuthentica

我在.NET MVC 4.5设置中使用OWIN进行cookie身份验证.我在Startup.Auth.cs(下面的代码)中设置了cookie认证配置,我想访问在控制器中的CookieAuthenticationOptions中设置的LoginPath,以便如果由于某种原因,我的LoginPath更改,我只需要更改它在一个地方.所以只是寻找类似的东西

context.GetCookieAuthenticationOptions().LoginPath

有没有办法访问Startup.Auth.cs之外的CookieAuthenticationOptions,或者是我唯一的选择,可以在Web.config中添加一个appSetting,然后再使用它？

Startup.Auth.cs代码,我想访问此文件之外的LoginPath.

app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,LoginPath = new PathString("Login"),SlidingExpiration = true,ExpireTimeSpan = _expirationTimeSpan,Provider = new CookieAuthenticationProvider
            {
                // Enables the application to validate the security stamp when the user logs in.
                // This is a security feature which is used when you change a password or add an external login to your account.  
                OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager,ApplicationUser>(
                    validateInterval: TimeSpan.FromMinutes(30),regenerateIdentity: (manager,user) => user.GenerateUserIdentityAsync(manager,DefaultAuthenticationTypes.ApplicationCookie))
            },});

var cookieOptions = new CookieAuthenticationOptions
{
    // ...
    LoginPath = new PathString("/Account/Login"),// ...
};

app.UseCookieAuthentication(cookieOptions);
app.CreatePerOwinContext(() => new MyCookieAuthOptions(cookieOptions));

var cookieOptions = HttpContext.GetOwinContext().Get<MyCookieAuthOptions>().Options;

public class MyCookieAuthOptions : IDisposable
{
    public MyCookieAuthOptions(CookieAuthenticationOptions cookieOptions)
    {
        Options = cookieOptions;
    }

    public CookieAuthenticationOptions Options { get; }

    public void Dispose()
    {

    }
}
