创建一个Cookie缓存，进行接口防抖

1. 新创建一个Cookie缓存 

Name：SavePInformation

HttpCookie newCookie = new HttpCookie("request");
newCookie["SavePInformation"] = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
newCookie.Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(newCookie);

2.  获取名字为“SavePInformation”缓存的值 进行逻辑判断

HttpCookie cookie = Request.Cookies["request"];
var preRequestDate = Convert.ToDateTime(cookie["SavePInformation"]);
if ((DateTime.Now - preRequestDate).TotalSeconds < 2)
{
    return ErrorMsg("您操作得太快了，休息一下吧！");
}
