page - Uploadify(sesión y autenticación) con ASP.NET MVC

forms asp net core

Question

Cuando uso Authorize filter en una acción o un controlador utilizado por uplodify ( http://www.uploadify.com/ ) la acción no se alcanza ...

además, la sesión no se recupera.

Encontré esto para recuperar la sesión del usuario:

¿Pero cómo usarlo con el filtro [Authorize] y la sesión recuperada?

Answer 1

Esta solución funciona genial. Traducí el código a vb si alguien lo quiere:

    Protected Sub Application_BeginRequest(ByVal sender As Object, ByVal e As System.EventArgs)
    ''we guess at this point session is not already retrieved by application so we recreate cookie with the session id...
    Try
        Dim session_param_name = "ASPSESSID"
        Dim session_cookie_name = "ASP.NET_SessionId"

        If Not HttpContext.Current.Request.Form(session_param_name) Is Nothing Then
            UpdateCookie(session_cookie_name, HttpContext.Current.Request.Form(session_param_name))
        ElseIf Not HttpContext.Current.Request.QueryString(session_param_name) Is Nothing Then
            UpdateCookie(session_cookie_name, HttpContext.Current.Request.QueryString(session_param_name))
        End If
    Catch ex As Exception
    End Try


    Try
        Dim auth_param_name = "AUTHID"
        Dim auth_cookie_name = FormsAuthentication.FormsCookieName

        If Not HttpContext.Current.Request.Form(auth_param_name) Is Nothing Then
            UpdateCookie(auth_cookie_name, HttpContext.Current.Request.Form(auth_param_name))
        ElseIf Not HttpContext.Current.Request.QueryString(auth_param_name) Is Nothing Then
            UpdateCookie(auth_cookie_name, HttpContext.Current.Request.QueryString(auth_param_name))
        End If
    catch ex As Exception
    End Try
End Sub

Private Sub UpdateCookie(ByVal cookie_name As String, ByVal cookie_value As String)
    Dim cookie = HttpContext.Current.Request.Cookies.Get(cookie_name)
    If cookie Is Nothing Then
        cookie = New HttpCookie(cookie_name)
    End If
    cookie.Value = cookie_value
    HttpContext.Current.Request.Cookies.Set(cookie)
End Sub

Aquí está la parte para la asignación de la variable javascript:

var auth = "<%=IIf(Request.Cookies(FormsAuthentication.FormsCookieName) Is Nothing, "", Request.Cookies(FormsAuthentication.FormsCookieName).Value)%>";
var ASPSESSID = "<%=Session.SessionID%>";

Tal vez alguien que trabaje en VB pueda beneficiarse de eso.

Answer 2

Para código convertido VB * comience el bloque de código con <% # en vez de <% =

es decir

var auth=''<%# IIf(Request.Cookies(FormsAuthentication.FormsCookieName) Is Nothing, "", 
     Request.Cookies(FormsAuthentication.FormsCookieName).Value)%>'';

var ASPSESSID = ''<%# Session.SessionID%>'';

Para corregir esto, le propongo una solución ... Envíe el valor de cookie de autenticación y el valor de la cookie de id de sesión con uploadify y vuelva a crearlo antes de recuperar la sesión.

aquí está el código para implementar en la vista:

<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 }
    });

Y luego en 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);
    }

Y listo, con ese método es totalmente transparente.

Espero que ayude a algunos !! ;)

EDITADO : use formData en lugar de scriptData
