我查看了ASP.NET身份,它看起来非常复杂且难以理解。基本上我想知道的是在登录时授权用户的最简单方法,因此[授权]数据注释将允许他们通过。

请按照以下步骤操作:

安装以下NuGet包

  • Microsoft.Owin
  • Microsoft.Owin.Host.SystemWeb
  • Microsoft.Owin.Security
  • Microsoft.Owin.Security.Cookies

在App_Start文件夹中,添加如下所示的AuthConfig:

public static class AuthConfig
{
    public const string DefaultAuthType = "DefaultAppCookie"; //example
    public const string LoginPath = "System/SignIn"; //example

    public static void ConfigureAuth(IAppBuilder app)
    {
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthType,
            LoginPath = new PathString(LoginPath)
        });
    }
}

在项目的根路径中,添加一个类似于此

的Startup.cs
[assembly: OwinStartup(typeof(YourPorject.Startup))]
namespace YourPorject
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            AuthConfig.ConfigureAuth(app);
        }
    }

}

验证用户(通常在登录操作中):

//user = the user that is loggin on, retrieved from database 
List<Claim> claims = new List<Claim>
            {
                new Claim(ClaimTypes.Name, user.Name),
                new Claim(ClaimTypes.Email, user.Email),
                //some other claims
            };

ClaimsIdentity identity = new ClaimsIdentity(claims, AuthConfig.DefaultAuthType);
IAuthenticationManager authManager = Request.GetOwinContext().Authentication;
authManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent }, identity);

您需要添加ClaimTypes.Role来授权特定角色。
