cookies的简单读写方法
一、cookie的写入
//定义COOKIES，实例化HttpCookie类并添加值
HttpCookie cookie = new HttpCookie(key, value);
//设置保存时间
cookie.Expires = DateTime.Now.AddDays(1);
//添加当前实例化的cookie
Response.Cookies.Add(cookie);
二、cookie的读取
public static string GetOwner()
{
if (HttpContext.Current.Request.Cookies[key] == null)
{
throw new Exception("您没有登录系统或会话已过期,请重新登录");
}
else
{
//得到用户数据
HttpCookie cook = HttpContext.Current.Request.Cookies[key];
return HttpUtility.UrlDecode(cook.Value);
}
}
