是的你可以。身份验证和授权部分独立工作。如果您有自己的身份验证服务,则可以只使用 OWIN 的授权部分。考虑你已经有一个UserManager
这验证了username
and password
。因此,您可以在回发登录操作中编写以下代码:
[HttpPost]
public ActionResult Login(string username, string password)
{
if (new UserManager().IsValid(username, password))
{
var ident = new ClaimsIdentity(
new[] {
// adding following 2 claim just for supporting default antiforgery provider
new Claim(ClaimTypes.NameIdentifier, username),
new Claim("http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider", "ASP.NET Identity", "http://www.w3.org/2001/XMLSchema#string"),
new Claim(ClaimTypes.Name,username),
// optionally you could add roles if any
new Claim(ClaimTypes.Role, "RoleName"),
new Claim(ClaimTypes.Role, "AnotherRole"),
},
DefaultAuthenticationTypes.ApplicationCookie);
HttpContext.GetOwinContext().Authentication.SignIn(
new AuthenticationProperties { IsPersistent = false }, ident);
return RedirectToAction("MyAction"); // auth succeed
}
// invalid username or password
ModelState.AddModelError("", "invalid username or password");
return View();
}
你的用户管理器可以是这样的:
class UserManager
{
public bool IsValid(string username, string password)
{
using(var db=new MyDbContext()) // use your DbConext
{
// for the sake of simplicity I use plain text passwords
// in real world hashing and salting techniques must be implemented
return db.Users.Any(u=>u.Username==username
&& u.Password==password);
}
}
}
最后,您可以通过添加一个来保护您的操作或控制器Authorize
属性。
[Authorize]
public ActionResult MySecretAction()
{
// all authorized users can use this method
// we have accessed current user principal by calling also
// HttpContext.User
}
[Authorize(Roles="Admin")]
public ActionResult MySecretAction()
{
// just Admin users have access to this method
}
