Core中Cookie和Session的新用法

 public void SetCookies(string key, string value, int minutes = 30)
        {
            HttpContext.Response.Cookies.Append(key, value, new CookieOptions
            {
                Expires = DateTime.Now.AddMinutes(minutes),
                HttpOnly = true,
                Secure = true,
                IsEssential = true
            });
        }

        /// <summary>
        /// 获取cookies
        /// </summary>
        /// <param name="key">键</param>
        /// <returns>返回对应的值</returns>
        public string GetCookies(string key)
        {
            HttpContext.Request.Cookies.TryGetValue(key, out string value);
            if (string.IsNullOrEmpty(value))
                value = string.Empty;
            return value;
        }
        /// <summary>

        {

        HttpContext.Session.SetString("MyTestValue", "123456");
        string Values = HttpContext.Session.GetString("MyTestValue");
