在ASP.NET和ASP.NET核心站点上共享OWIN Cookie

我有一个现有的ASP.NET WebForms应用程序，当前正在使用表单身份验证 . 我们正在ASP.NET Core 2中构建一个新站点，它是IIS中的虚拟目录 . 我们需要在两个站点之间共享身份验证，以便用户无需登录两次 .

我已将.NET Core应用程序配置为使用cookie身份验证，如下所示：

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(options =>
    {
        options.Cookie.Name = "cred";
        options.LoginPath = new PathString("/Login");
        options.LogoutPath = new PathString("/Logout");
    });

登录时，使用此代码创建cookie，并且用户已成功登录：

var claims = new List<Claim>
{
    new Claim(ClaimTypes.Name, user.UserName),
    new Claim("FullName", $"{user.FirstName} {user.LastName}"),
    new Claim(ClaimTypes.Role, user.UserType),
    new Claim(ClaimTypes.Email, user.EmailAddress),
};

var claimsIdentity = new ClaimsIdentity(claims, CookieAuthenticationDefaults.AuthenticationScheme);
return new ClaimsPrincipal(claimsIdentity);

var _authenticationProperties = new AuthenticationProperties
{
    IsPersistent = true,
    ExpiresUtc = DateTime.UtcNow.AddMinutes(60),
    AllowRefresh = true
};
await _httpContextAccessor.HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal, _authenticationProperties);

在我的WebForms应用程序中，我在web.config上将Authentication设置为None，并将其配置为使用Microsoft.Owin.Security.Cookies和Interop，如下所示：

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    CookieName = "cred",
    AuthenticationType = CookieAuthenticationDefaults.AuthenticationType,
    LoginPath = new PathString("/LoginPage.aspx"),
    CookieManager = new SystemWebCookieManager(), //Owin and ASP.NET do not play nicely with Response Cookies.  Remove at your peril,
    ExpireTimeSpan = TimeSpan.FromHours(1),
    TicketDataFormat = new AspNetTicketDataFormat(
        new DataProtectorShim(
            DataProtectionProvider.Create(new DirectoryInfo(@"d:\keys\"), (builder) => { builder.SetApplicationName("Aliss");})
                .CreateProtector("Microsoft.AspNetCore.Authentication.Cookies.CookieAuthenticationMiddleware", "Cookies", "v2"))),
});
