C# 为什么要使用；索赔类型。参与者“；return"；阿克特；？

我有以下资料：

/* create claims */
const string actorClaimValue = "actor";

SecurityToken sendToken = new JwtSecurityToken(
    claims: new List<Claim> {
        new Claim(
            type: ClaimTypes.Actor,
            value: actorClaimValue
        ),
    }
);

JwtSecurityTokenHandler sendHandler = new JwtSecurityTokenHandler();

string sendTokenString = sendHandler.WriteToken( sendToken );

Console.Out.WriteLine( sendTokenString );
// eyJ0eXAiOiJKV1QiLCJhbGciOiJub25lIn0.eyJhY3RvcnQiOiJhY3RvciJ9.

/* get claims */
JwtSecurityTokenHandler receiveHandler = new JwtSecurityTokenHandler();
JwtSecurityToken token = (JwtSecurityToken)receiveHandler.ReadToken( sendTokenString );

Claim actorClaim = token.Claims.FirstOrDefault( c => c.Type == ClaimTypes.Actor );
Console.Out.WriteLine( actorClaim == null );
// True

foreach( Claim claim in token.Claims ) {
    Console.Out.WriteLine( "{0}: {1}", claim.Type, claim.Value );
    // actort: actor
}

导致索赔类型为“actort”

编辑：

我只是尝试了

ClaimTypes.Role

而不是

ClaimTypes.Actor

，它很有效。。。可能的错误？

发现的错误与包含的错误相反

因为我使用的是

JwtSecurityToken

s，所以在过滤

claim-actorClaim=token.Claims.FirstOrDefault（c=>c.type==ClaimTypes.Actor）之前，我应该使用映射找出我得到的索赔类型值

public const string Actor = "http://schemas.xmlsoap.org/ws/2009/09/identity/claims/actor"
