当我使用Authorize过滤器对一个action或uplodify使用的控制器(
http://www.uploadify.com/)操作没有到达…
而且Session没有被检索。
我发现这个检索用户会话：
但是如何使用它与[授权]过滤器和检索会话？
解决方法
要纠正这个，我建议你一个解决方案…发送aify cookie值和会话id cookie值与uploadify并重新创建会话之前检索。
这里是在视图中隐含的代码：
<script>
var auth = "<% = Request.Cookies[FormsAuthentication.FormsCookieName]==null ? string.Empty : Request.Cookies[FormsAuthentication.FormsCookieName].Value %>";
var ASPSESSID = "<%= Session.SessionID %>";
$("#uploadifylogo").uploadify({
...
formData: { ASPSESSID: ASPSESSID,AUTHID: auth }
});
然后在Global.asax：
protected void Application_BeginRequest(object sender,EventArgs e)
{
/* we guess at this point session is not already retrieved by application so we recreate cookie with the session id... */
try
{
string session_param_name = "ASPSESSID";
string session_cookie_name = "ASP.NET_SessionId";
if (HttpContext.Current.Request.Form[session_param_name] != null)
{
UpdateCookie(session_cookie_name,HttpContext.Current.Request.Form[session_param_name]);
}
else if (HttpContext.Current.Request.QueryString[session_param_name] != null)
{
UpdateCookie(session_cookie_name,HttpContext.Current.Request.QueryString[session_param_name]);
}
}
catch
{
}
try
{
string auth_param_name = "AUTHID";
string auth_cookie_name = FormsAuthentication.FormsCookieName;
if (HttpContext.Current.Request.Form[auth_param_name] != null)
{
UpdateCookie(auth_cookie_name,HttpContext.Current.Request.Form[auth_param_name]);
}
else if (HttpContext.Current.Request.QueryString[auth_param_name] != null)
{
UpdateCookie(auth_cookie_name,HttpContext.Current.Request.QueryString[auth_param_name]);
}
}
catch
{
}
}
private void UpdateCookie(string cookie_name,string cookie_value)
{
HttpCookie cookie = HttpContext.Current.Request.Cookies.Get(cookie_name);
if (null == cookie)
{
cookie = new HttpCookie(cookie_name);
}
cookie.Value = cookie_value;
HttpContext.Current.Request.Cookies.Set(cookie);
}
瞧，用这种方法它是完全透明的。
希望它帮助一些！
