推荐答案

用户属性返回 IPrincipal 实例。要访问声明，您需要将其转换为 ClaimsPrincipal 。

The User property returns an IPrincipal instance. To access the claims, you'll need to cast that to a ClaimsPrincipal.

public static class ClaimsExtensions
{
    public static Claim FindClaim(this IPrincipal user, string claimType)
    {
        if (user == null) throw new ArgumentNullException(nameof(user));
        if (string.IsNullOrEmpty(claimType)) throw new ArgumentNullException(nameof(claimType));
        
        var claimsPrincipal = user as ClaimsPrincipal;
        return claimsPrincipal?.FindFirst(claimType);
    }
    
    public static string GetEmail(this IPrincipal user)
    {
        if (user == null) throw new ArgumentNullException(nameof(user));
        return FindClaim(user, ClaimTypes.Email)?.Value;
    }
    
    public static string GetSurname(this IPrincipal user)
    {
        if (user == null) throw new ArgumentNullException(nameof(user));
        return FindClaim(user, ClaimTypes.Surname)?.Value;
    }
    
    public static int? GetUserId(this IPrincipal user)
    {
        if (user == null) throw new ArgumentNullException(nameof(user));
        
        string value = FindClaim(user, ClaimTypes.Sid)?.Value;
        if (string.IsNullOrEmpty(value)) return default(int?);
        
        int result;
        return int.TryParse(value, out result) ? result : default(int?);
    }
}
