Valeurs de revendication complexes dans .NET Framework avec System.Security.Claims

Je développe une application Web avec un jeton porteur Asp.Net 5 MVC, Owin et Oauth2 en tant que type d’authentification.

Suite à ce guide qui ajoute une revendication complexe personnalisée Json sérialisée à une instance de Microsoft.IdentityModel.Claims.ClaimsIdentity , j’ai essayé de répliquer le même exemple à l’aide de ClaimsIdentity sur l’espace de noms System.Security.Claims .

Malheureusement, il semble que l’ajout d’une complexClaim à l’instance ClaimsIdentity la ClaimsIdentity informations de type de classe dérivée et la revendication soit stockée sous la forme d’une System.Security.Claims.Claim .

 var complexClaim = new ComplexClaim(@"http://it.test/currentpassport", passport); var claims = new List() { complexClaim }; identity.AddClaims(claims); 

Lorsque j’essaie de récupérer la revendication d’identité, le transtypage vers un type ComplexClaim donne une valeur null.

 var passportClaim = identity.Claims.FirstOrDefault(c=>c.Type == @"http://it.test/currentpassport") as ComplexClaim; 

Le même exemple fonctionne parfaitement en utilisant Microsoft.IdentityModel.Claims .

Des allusions?

Voici le code complet porté:

 using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using Newtonsoft.Json; using System.Security.Claims; namespace ConsoleApplication1 { class Program { private static ClaimsIdentity identity = new ClaimsIdentity(); static void Main(ssortingng[] args) { var oldPassport = CreatePassport(); identity.AddPassport(oldPassport); var britishCitizen = identity.IsBritishCitizen(); var hasExpired = identity.IsCurrentPassportExpired(); Console.WriteLine(hasExpired); Console.ReadLine(); } private static UKPassport CreatePassport() { var passport = new UKPassport( code: PassportCode.GBR, number: 123456789, expiryDate: DateTime.Now); return passport; } } public static class ClaimsIdentityExtensions { public static void AddPassport(this ClaimsIdentity identity, UKPassport passport) { var complexClaim = new ComplexClaim(@"http://it.test/currentpassport", passport); var claims = new List() { complexClaim }; identity.AddClaims(claims); } public static bool IsCurrentPassportExpired(this ClaimsIdentity identity) { var passport = GetPassport(identity, @"http://it.test/currentpassport"); return DateTime.Now > passport.ExpiryDate; } public static bool IsBritishCitizen(this ClaimsIdentity identity) { var passport = GetPassport(identity, @"http://it.test/currentpassport"); return passport.Code == PassportCode.GBR; } private static UKPassport GetPassport(this ClaimsIdentity identity, ssortingng passportType) { var passportClaim = identity.Claims.FirstOrDefault(c=>c.Type == @"http://it.test/currentpassport") as ComplexClaim; return passportClaim.Value; } } public enum PassportCode { GBR, GBD, GBO, GBS, GBP, GBN } public class ComplexClaim : Claim where T : ClaimValue { public ComplexClaim(ssortingng claimType, T claimValue) : this(claimType, claimValue, ssortingng.Empty) { } public ComplexClaim(ssortingng claimType, T claimValue, ssortingng issuer) : this(claimType, claimValue, issuer, ssortingng.Empty) { } public ComplexClaim(ssortingng claimType, T claimValue, ssortingng issuer, ssortingng originalIssuer) : base(claimType, claimValue.ToSsortingng(), claimValue.ValueType(), issuer, originalIssuer) { } public new T Value { get { return JsonConvert.DeserializeObject(base.Value); } } } public class UKPassport : ClaimValue { public const ssortingng Name = "UKPassport"; private readonly PassportCode code; private readonly int number; private readonly DateTime expiryDate; public UKPassport(PassportCode code, int number, DateTime expiryDate) { this.code = code; this.number = number; this.expiryDate = expiryDate; } public PassportCode Code { get { return this.code; } } public int Number { get { return this.number; } } public DateTime ExpiryDate { get { return this.expiryDate; } } public override ssortingng ValueType() { return @"http://it.test/currentpassport"; } } public abstract class ClaimValue { public abstract ssortingng ValueType(); public override ssortingng ToSsortingng() { return JsonConvert.SerializeObject(this); } } } 

 public static explicit operator UKPassport(Claim c) { return (c == null ? null:JsonConvert.DeserializeObject (c.Value)); } 

 private static UKPassport GetPassport(this ClaimsIdentity identity, ssortingng passportType) { return (UKPassport)identity.Claims.FirstOrDefault(c => c.Type == @"http://it.test/currentpassport"); }
