.Net Core:身份认证组件

类库组件

.NET Core的身份认证使用的类库如下图：常用的

Microsoft.AspNetCore.Authorization

Microsoft.AspNetCore.Authorization.Cookies

Microsoft.AspNetCore.Authorization.OpenIdConnect

Microsoft.AspNetCore.Authorization.OAuth

演示下基于Cookies的

Startup.cs添加管道支持：

ConfigureService:

services.AddAuthorization(); 

Configure:

 app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AuthenticationScheme = "Cookie",
        LoginPath = new PathString("/Account/Login"),
        AccessDeniedPath = new PathString("/Account/Forbidden"),
        AutomaticAuthenticate = true,
        AutomaticChallenge = true
    }); 

环境支持配置完以后；老套路简单使用一下

Controller或者Action添加[Authorize]；Claim声明一些属性,加入到ClaimIdentity(IIdentity)属性标识；通过ClaimIdentity再创建身份ClaimPrincipal（IPrincipal）出来;存入Cookie

AccountController ：

public class AccountController : Controller
    {
        [Authorize]
        // GET: /<controller>/
        public IActionResult Index()
        {
            return View();
        }

        [HttpGet]
        public IActionResult Login()
        {
            return View();
        }

        [HttpPost]
        public async Task<IActionResult> Login(LoginViewModel model)
        {
            if (model.Username.Equals("admin")&&model.Password.Equals(""))
            {
                //名片
                List<Claim> claims = new List<Claim>
                {
                    new Claim(ClaimTypes.Name,model.Username)
                };
                //身份
                ClaimsPrincipal principal = new ClaimsPrincipal(new ClaimsIdentity(claims,"Login"));

                await HttpContext.Authentication.SignInAsync("Cookie", principal, new AuthenticationProperties {
                    ExpiresUtc = DateTime.UtcNow.AddMinutes(),
                    IsPersistent=false,
                    AllowRefresh=false,
                });

                return RedirectToAction("Index","Account");

            }
            else
            {
                return Content("用户名密码错误！");
            }

        }

        public async Task<IActionResult> Logout()
        {
            await HttpContext.Authentication.SignOutAsync("Cookie");

            return RedirectToAction("Index", "Home");
        }

    public class LoginViewModel
    {
        [Required]
        public string Username { get; set; }
        [Required]
        public string Password { get; set; }

    }

@{
    ViewData["Title"] = "Login";
}
