[英]How to invalidate bearer token at server
I save all of the generated bearer tokens into a database at sign-in time.我在登录时将所有生成的不记名令牌保存到数据库中。 Now I want to check if the request bearer does not exists in database, reject it.现在我想检查数据库中是否不存在请求承载,拒绝它。 Where should I put it?我应该把它放在哪里?
Note that I want this to happen in the Owin pipeline.请注意,我希望这发生在 Owin 管道中。 ( Not in the webapi pipeline. For example inside the [Authorize]
attribute) (不在webapi 管道中。例如在[Authorize]
属性中)
Inherit from OAuthBearerAuthenticationProvider
like this :像这样从OAuthBearerAuthenticationProvider
继承:
public class ApplicationOAuthBearerAuthenticationProvider : OAuthBearerAuthenticationProvider
{
public override Task ValidateIdentity(OAuthValidateIdentityContext context)
{
var result= base.ValidateIdentity(context);
if (context.IsValidated )
{
var ticket = context.Ticket;
if (ticket != null && ticket.Identity.IsAuthenticated && ticket.Properties.ExpiresUtc > DateTime.UtcNow)
{
if (1==2)//TODO: put your server side condition here
{
context.SetError("HaHa!");
}
}
}
return result;
}
}
and use it in your startup.cs
class like this :并在您的startup.cs
类中使用它,如下所示:
public partial class Startup
{
public void Configuration(IAppBuilder app)
{
app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions
{
Provider = new ApplicationOAuthBearerAuthenticationProvider(),
});
}
}
