使用OWIN Cookie身份验证时无需数据库即可存储/检索用户数据

Question

How do I correctly store and retrieve data belonging to a user when using OWIN cookie authentication? No database is available. The data should preferably be available as long as the cookie remains valid. If that's not possible, it's acceptable if the user needs to re-login providing the data again if it is missing. Currently login is simply done using something similar to:

// Check credentials here

var claims = new List<Claim> { new Claim(ClaimTypes.Name, name) };

var id = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie);

HttpContext.GetOwinContext().Authentication.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent }, identity);

Answer 1

Cookie中间件负责保存您的Claimsidentity中的任何内容，因此您可以自由地将所需的任何数据放入ClaimsIdentity中，并且该数据在该Cookie的整个生命周期内都可用。
