ClaimsAuthenticationManager 与 IAuthenticationFilter 与 OWIN Forms 身份验证

使用ClaimsAuthenticationManager与IAuthenticationFilter与OWIN Forms身份验证

csharp
public class CustomClaimsAuthenticationManager : ClaimsAuthenticationManager
{
    public override ClaimsPrincipal Authenticate(string resourceName, ClaimsPrincipal incomingPrincipal)
    {
        // 自定义处理逻辑
        // 创建自定义的ClaimsPrincipal对象
        var customPrincipal = new ClaimsPrincipal();
        // 设置自定义的声明
        var customClaims = new List
        {
            new Claim(ClaimTypes.Name, "John Doe"),
            new Claim(ClaimTypes.Email, "john.doe@example.com"),
            new Claim(ClaimTypes.Role, "Admin")
        };
        // 将自定义声明添加到ClaimsIdentity中
        var customIdentity = new ClaimsIdentity(customClaims, "CustomAuthenticationType");
        customPrincipal.AddIdentity(customIdentity);
        return customPrincipal;
    }
}

csharp
public class CustomAuthenticationFilter : IAuthenticationFilter
{
    public async Task AuthenticateAsync(HttpAuthenticationContext context, CancellationToken cancellationToken)
    {
        // 自定义身份验证逻辑
        if (!context.Request.Headers.Contains("Authorization"))
        {
            context.ErrorResult = new AuthenticationFailureResult("Missing Authorization header", context.Request);
            return;
        }
        // 身份验证通过，创建ClaimsIdentity对象
        var identity = new ClaimsIdentity("CustomAuthenticationType");
        identity.AddClaim(new Claim("CustomClaim", "CustomValue"));
        // 将ClaimsIdentity对象设置到当前请求的Principal中
        context.Principal = new ClaimsPrincipal(identity);
    }
    public async Task ChallengeAsync(HttpAuthenticationChallengeContext context, CancellationToken cancellationToken)
    {
        // 空实现，不需要进行挑战
    }
    public bool AllowMultiple => false;
}

csharp
public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        // 配置Forms身份验证
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Account/Login")
        });
        // 其他中间件配置
    }
}
public class AccountController : Controller
{
    [HttpGet]
    public ActionResult Login()
    {
        return View();
    }
    [HttpPost]
    public ActionResult Login(LoginViewModel model)
    {
        // 验证用户名和密码
        // 创建ClaimsIdentity对象
        var identity = new ClaimsIdentity(DefaultAuthenticationTypes.ApplicationCookie);
        identity.AddClaim(new Claim(ClaimTypes.Name, model.Username));
        // 进行身份验证
        var context = Request.GetOwinContext();
        var authenticationManager = context.Authentication;
        authenticationManager.SignIn(identity);
        // 跳转到首页
        return RedirectToAction("Index", "Home");
    }
}
