c# – 充分利用具有n(3)层架构的MVC Owin身份

我一直在学习开箱即用的 Owin Identity,我喜欢它为我们提供用户管理的易用性.然后我遇到的问题是它通过ApplicationDbContext直接与EF(貌似)进行交互,这是我不想要的.我更喜欢使用我的3层架构,IE它与服务层(BLL)交互,后者与EF交互.我找不到模板,教程,甚至起点来维护所提供的所有功能并实现我想要的分离.

那么有没有办法在MVC Identity包中使用服务层代替ApplicationDbContext.

解决方法

如果要使用现有数据库/表,则不必使用整个ASP.Net标识.相反,您可以使用Owin Cookie身份验证中间件.

我在GitHub处有示例代码.如果要测试它,只需在AccountController.cs设置一个断点,然后返回true.

以下是配置中间件和登录的两个主要类别.

Startup.cs

public class Startup
{
   public void Configuration(IAppBuilder app)
   {
      app.UseCookieAuthentication(new CookieAuthenticationoptions
      {
        AuthenticationType = "ApplicationCookie",LoginPath = new PathString("/Account/Login")
      });
   }
}

OwinAuthenticationService.cs

public class OwinAuthenticationService : IAuthenticationService
{
    private readonly HttpContextBase _context;
    private const string AuthenticationType = "ApplicationCookie";

    public OwinAuthenticationService(HttpContextBase context)
    {
        _context = context;
    }

    public void SignIn(User user)
    {
        IList<Claim> claims = new List<Claim>
            {
                new Claim(ClaimTypes.Name,user.UserName),new Claim(ClaimTypes.Givenname,user.FirstName),new Claim(ClaimTypes.Surname,user.LastName),};

        ClaimsIdentity identity = new ClaimsIdentity(claims,AuthenticationType);

        IOwinContext context = _context.Request.GetowinContext();
        IAuthenticationManager authenticationManager = context.Authentication;

        authenticationManager.SignIn(identity);
    }

    public void SignOut()
    {
        IOwinContext context = _context.Request.GetowinContext();
        IAuthenticationManager authenticationManager = context.Authentication;

        authenticationManager.SignOut(AuthenticationType);
    }
}
