如何定义system . security . claims . claimprincipal作为gRPC中的请求参数?

Question

我想在。net代码下使用gRPC构建授权服务。为了做到这一点，我需要将system . security . claims . claimprincipal对象作为请求参数从调用者传递给服务器，以便服务器可以使用它来授权调用者。但我不知道如何做到这一点——我如何为一个标准库类定义一个。proto。我该怎么办?

我也在做同样的事情，使用protobuf-net grpc库。由于许多Identity/Security类(如果您正在使用它们)来自Microsoft，您需要公开它们的成员以进行序列化;你可以使用:

RuntimeTypeModel.Default.Add(typeof(SignInResult), false).Add(
nameof(SignInResult.Succeeded),
nameof(SignInResult.IsLockedOut),
nameof(SignInResult.IsNotAllowed),
nameof(SignInResult.RequiresTwoFactor)
);

并列出需要通过gRpc公开的成员。至于claimprincipal，具体来说，这是我目前正在尝试实现的。对于Claims，我使用代理类:

RuntimeTypeModel.Default.Add(typeof(Claim), true).SetSurrogate(typeof(ClaimSurrogate));
public class ClaimSurrogate
{
[DataMember, ProtoMember(1)]
public string Type { get; set; }
[DataMember, ProtoMember(2)]
public ClaimsIdentity Subject { get; set; }
[DataMember, ProtoMember(3)]
public IDictionary<string, string> Properties { get; set; }
[DataMember, ProtoMember(4)]
public string OriginalIssuer { get; set; }
[DataMember, ProtoMember(5)]
public string Issuer { get; set; }
[DataMember, ProtoMember(6)]
public string ValueType { get; set; }
[DataMember, ProtoMember(7)]
public string Value { get; set; }
public static implicit operator ClaimSurrogate(Claim claim)
{
if (claim == null)
return null;
return new ClaimSurrogate()
{
Type = claim.Type,
Subject = claim.Subject,
Properties = claim.Properties,
OriginalIssuer = claim.OriginalIssuer,
Issuer = claim.Issuer,
ValueType = claim.ValueType,
Value = claim.Value
};
}
public static implicit operator Claim(ClaimSurrogate surrogate)
{
if (surrogate == null)
return null;
return new Claim(surrogate.Type, surrogate.Value, surrogate.ValueType, surrogate.Issuer, surrogate.OriginalIssuer, surrogate.Subject);
}
}

我假设claimprincipal可以用同样的方式完成，但是，我遇到了麻烦。我就是这样看到你的问题的……实际上，通过试图提供一个答案…实际上，我刚刚意识到我忽略了什么，我还需要为ClaimsIdentity

设置代理到目前为止，我需要"第三方"类的代理。只有属性。claimprincipal具有这些类型的属性，ClaimsIdentity也具有这些类型的属性(Claim也是)。如果ClaimsIdentitySurrogate做到了，我将更新/注释

更新:

是的，可以做到。像上面的例子一样，ClaimsIdentity和IIdentity将需要代理。这些类被用作claimprincipal中的成员/属性。ClaimsIdentity:你可以混淆set代孕和Add(nameof(…))，因为它有get only和get/sets (get/sets在Add部分)。不要在ClaimsIdentity代理中包含Actor，因为它会在服务启动时创建一个永不结束的循环。如果要包含它，请确保它不是DataMember/Protomember。并且(私有)在代理操作符中设置它。Claims也一样

本质上，任何具有引用父类成员的代理，或者具有引用该父类的代理的另一类型的代理，都将创建一个循环引用，并在启动时出错。

IIdentity:这很简单，只是RuntimeTypeModel.Default.Add (typeof (IIdentity),假)。

最后(当我认为我有这个更新时，我发布了这个更新，但是，在所有UT测试和更改等中，我发布得有点早;(在对ClaimPrincipal代理类进行重大更改后)....

您需要一个IIdentity虚拟类，它将用于您的ClaimPrincipal代理，而不是IIdentity Identity {get;set;}。这个虚拟类应该继承IIdentity，例如

[DataContract]
public class IIdentityFraud : System.Security.Principal.IIdentity

并且在代理的隐式操作符中:

IIdentityFraud identityfraud = null;
if (claimPrincipal.Identity != null)
{
identityfraud = new IIdentityFraud(claimPrincipal.Identity.AuthenticationType, claimPrincipal.Identity.Name, claimPrincipal.Identity.IsAuthenticated);
}
