🛡️ TL.ClaimsPrincipalExtensionsLibrary

NuGet .NET License: MIT

Strongly-typed ClaimsPrincipal extensions for ASP.NET Core: clean, safe access to user IDs, roles, emails, and authentication claims.
Extensões fortemente tipadas para ClaimsPrincipal no ASP.NET Core: acesso limpo e seguro a IDs, roles, e-mails e claims de autenticação.

O TL.ClaimsPrincipalExtensionsLibrary é uma biblioteca .NET BCL pura voltada para a simplificação e segurança na extração de dados de autenticação e autorização a partir de instâncias de System.Security.Claims.ClaimsPrincipal (HttpContext.User).

📦 Instalação

Adicione o pacote ao seu projeto através do .NET CLI:

dotnet add package TL.ClaimsPrincipalExtensionsLibrary

🚀 Funcionalidades Principais

Método Retorno Descrição
IsAuthenticated() bool Verifica se o principal possui identidade ativa e autenticada com segurança.
Id() long Extrai o identificador numérico da claim sub (Subject ID).
ClaimSub() string? Retorna o valor original em texto da claim sub.
Email() string? Retorna o endereço de email autenticado (email ou ClaimTypes.Email).
FullName() string? Retorna o nome completo do usuário autenticado (name ou ClaimTypes.Name).
HasRole(role) bool Valida se o usuário possui determinado papel/permissão de acesso.
ClaimRoles() IEnumerable<string> Retorna todas as roles associadas ao usuário no token.
Roles<T>() IEnumerable<T> Faz o parse tipado das roles do usuário para um tipo enum de autorização.
Claim(claimType) Claim? Obtém a primeira ocorrência da claim especificada.

💡 Exemplos de Uso

using ClaimsPrincipalExtensionsLibrary;
using Microsoft.AspNetCore.Http;

public class PedidoController
{
    public void Processar(HttpContext context)
    {
        var user = context.User;

        // 1. Verificação de Autenticação Segura
        if (!user.IsAuthenticated())
        {
            throw new UnauthorizedAccessException("Usuário não autenticado.");
        }

        // 2. Extração Simplificada de Dados de Identidade
        long usuarioId = user.Id();
        string email = user.Email() ?? "desconhecido@empresa.com";
        string nome = user.FullName() ?? "Usuário";

        // 3. Validação de Papel/Role
        if (user.HasRole("Administrador"))
        {
            Console.WriteLine($"Acesso prioritário liberado para {nome} (ID: {usuarioId})");
        }
    }
}
