在 ASP.Net MVC 中使用 OpenIdConnect 进行身份验证后重定向用户 [英] Redirect user after authentication with OpenIdConnect in ASP.Net MVC
问题描述
我在我的 asp.net mvc 应用程序中使用 OpenIdConnect 提供程序和 Owin/Katana 进行身份验证.OpenIdConnect 提供针对 Active Directory 对用户进行身份验证.我想在用户通过身份验证后进行简单的授权检查,并将用户重定向到另一个视图.
I am using OpenIdConnect provider with Owin/Katana for authentication in my asp.net mvc application. OpenIdConnect Provide authenticates users against Active Directory. I wanted to do a simple authorization check once the user is authenticated and redirect the user to another view.
app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions()
{
Authority = "url",
Scope="scopes",
ResponseType = "response",
ClientId = "clientid",
SignInAsAuthenticationType = "Cookies",
Notifications = new OpenIdConnectAuthenticationNotifications()
{
SecurityTokenValidated = (context) =>
{
var identity = context.AuthenticationTicket.Identity;
var emailClaim = identity.Claims.Where(r => r.Type == ClaimTypes.Email).FirstOrDefault();
var user = dbContext.Users.Where(u=>u.Email==emailClaim.Value);
if (user != null)
{
//add user information to claims.
identity.AddClaim(new Claim(CustomClaimTypes.PersonId, user.Name.ToString()));
}
else
{
//redirect to a page
}
return Task.FromResult(0);
}
}
});
如果用户不在我的数据库中,我如何重定向用户.
How can I redirect the user if he is not in my database.
推荐答案
我能够通过编写自定义 AuthorizeAttribute 并在我的应用程序中的每个类上使用它来实现这一点.在自定义授权属性中,我正在检查声明,如果授权检查成功,该声明将可用,如果未授权,则将用户重定向到单独的视图.
I was able to achieve this by writing custom AuthorizeAttribute and using it on every class in my application. In the custom authorize attribute I am checking for the a Claim which will be available if the authorization check is successful and redirecting the user to a separate view if not authorized.
public class CustomAuthorize : AuthorizeAttribute
{
public override void OnAuthorization(System.Web.Mvc.AuthorizationContext filterContext)
{
base.OnAuthorization(filterContext);
if (filterContext.HttpContext.User.Identity.IsAuthenticated)
{
if(UserClaims.PersonId == 0)
{
UrlHelper helper = new UrlHelper(filterContext.RequestContext);
string url = helper.Action("Unauthorized","Error",null,filterContext.HttpContext.Request.Url.Scheme);
filterContext.Result = new RedirectResult(url);
}
}
}
}
