.NET CORE cookie

.net core 有自己的cookie机制，不需要单独写js进行实现
statup.cs 文件中找到Configure方法
	//Cookie
	app.UseCookieAuthentication(new CookieAuthenticationOptions
	{
		AuthenticationScheme = "Cookie",// 验证方案名
		AutomaticAuthenticate = true,
		ExpireTimeSpan = TimeSpan.FromSeconds(30)//cookie过期时间
		AutomaticChallenge = true,
        AccessDeniedPath = new PathString("/System/Error") //访问拒绝跳到error页面
	});
	
页面选择登录状态保持，在登录成功之后设置cookie
	if (model.LoginState)
	{
		// cookie
		var identity = new ClaimsIdentity("Forms"); 
		identity.AddClaim(new Claim(ClaimTypes.Sid, model.LoginId));
		identity.AddClaim(new Claim(ClaimTypes.Rsa, model.Password)); 
		identity.AddClaim(new Claim(ClaimTypes.Name, Convert.ToString(model.LoginState)));
		var principal = new ClaimsPrincipal(identity);
		HttpContext.Authentication.SignInAsync("Cookie", principal, new AuthenticationProperties { IsPersistent = true });//是否解析
	}
	
解析cookie
	// cookie
	string loginId = CommonConstant.S_SPACE;
	string password = CommonConstant.S_SPACE;
	bool loginState = false;
	if (null != User.FindFirst(ClaimTypes.Sid)
		&& null != User.FindFirst(ClaimTypes.Rsa)
		&& null != User.FindFirst(ClaimTypes.Name))
	{
		loginId = User.FindFirst(ClaimTypes.Sid).Value; 
		password = User.FindFirst(ClaimTypes.Rsa).Value; 
		loginState = Convert.ToBoolean(User.FindFirst(ClaimTypes.Name).Value);// ログイン状態
	}
	
如果statup.cs文件中设置path
	//Cookie
	app.UseCookieAuthentication(new CookieAuthenticationOptions
	{
		AuthenticationScheme = "Cookie",
		AutomaticAuthenticate = true,
		ExpireTimeSpan = TimeSpan.FromSeconds(30)//cookie过期时间
		LoginPath = "/account/login"　　　　　      // 登录页
	});
后台login动作加入注解[AllowAnonymous],在保持状态之后页面可以直接跳转到login动作中
logout时HttpContext.Authentication.SignOutAsync("member");　　 // Startup.cs中配置的验证方案名
