復制代碼 代碼如下:
public class BasePage : System.Web.UI.Page
{
private string pageName;
public BasePage()
{
this.Page.PreLoad += Page_Load;
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Uri r = this.Request.Url;
pageName = r.AbsolutePath;
if (NeedToCheck())
{
if (!HasAuthentication())
{
HttpContext.Current.Response.Redirect("NoAuthenticationPage.ASPx");
}
}
}
}
private bool NeedToCheck()
{
if (pageName.Contains("NoAuthenticationPage.ASPx") || pageName == "Login.ASPx" )
{
return false;
}
return true;
}
private bool HasAuthentication()
{
//look into the config file or database,to see whether this page is in the allow accessing list of the role or not;
//the signature of the function is like this
//QueryInConfig(m_UserRole,pageName);
if (pageName.Contains("Default3.ASPx") && UserRole == "2")
{
return false;
}
return true;
}
protected HttpCookie _RequestCookie;
protected HttpCookie _ResponseCookie;
private bool b_IsNewCookie = true;
public string UserRole
{
get
{
return GetCookieValue("UserRole");
}
set
{
SetCookieValue("UserRole", value);
}
}
public string UserName
{
get
{
return GetCookieValue("UserName");
}
set
{
SetCookieValue("UserName", value);
}
}
protected void SetCookieValue(string name, string value)
{
SetResponseCookie();
_ResponseCookie[name] = value;
}
private string GetCookieValue(string name)
{
SetReqeustCookie();
if (_RequestCookie != null)
{
return _RequestCookie[name];
}
return null;
}
protected void SetReqeustCookie()
{
_RequestCookie = HttpContext.Current.Request.Cookies["Cookie_Name"];
}
protected void SetResponseCookie()
{
if (b_IsNewCookie)
{
HttpContext.Current.Response.Cookies.Remove("Cookie_Name");
_ResponseCookie = new HttpCookie("Cookie_Name");
DateTime dtNow = DateTime.Now;
TimeSpan tsMinute = new TimeSpan(0, 2, 0, 0);
_ResponseCookie.Expires = dtNow + tsMinute;
_ResponseCookie["UserRole"] = UserRole;
_ResponseCookie["UserName"] = UserName;
HttpContext.Current.Response.Cookies.Add(_ResponseCookie);
b_IsNewCookie = false;
}
}
}
