System.Web.UI.ViewStateException, Nieprawidłowy stan widoku

Question

Moja strona internetowa rzuca poniższe wyjątki codziennie i nie mogłem znaleźć rozwiązania. Zrobiłem kilka badań w Internecie i to jest to, co robię do tej pory. dodanie poniżej opcji do aspx nie rozwiąże problemu.

ValidateRequest = "false" EnableEventValidation = "false" ViewStateEncryptionMode = "nigdy" EnableViewStateMac = "false"

Również moja odsyłający URL jest prawidłowy adres URL i nie mam pojęcia jak to przekierować z dwoma (tymi samymi) parametrami. nie ma takiego linku na mojej stronie polecającej. Proszę pomóż.

UPDATE i mają stałe błędu przez sprasowanie ViewState od dołu połączenia http://www.codeproject.com/Articles/14733/ViewState-Compression

i stałe nieprawidłowej długość dla błędu podstawy tablicy-64 char zastępując oryginalna metoda z tym.

protected override object LoadPageStateFromPersistenceMedium() 
    { 
     string viewState = Request.Form["__VSTATE"]; 
     viewState = viewState.Replace(" ", "+"); 

     int mod4 = viewState.Length % 4; 
     if (mod4 > 0) 
     { 
      viewState += new string('=', 4 - mod4); 
     } 
     byte[] bytes = Convert.FromBase64String(viewState); 
     bytes = Compressor.Decompress(bytes); 
     LosFormatter formatter = new LosFormatter(); 
     return formatter.Deserialize(Convert.ToBase64String(bytes)); 
    } 

Dzięki wszystkim za pomoc :)

Answer 1

przykro mi powiedzieć, że to jednak witryna nie miał nic, i trzeba ponownie włączyć EventValidations jak najszybciej.

To, co widzisz, to an attempt to hack your site, wysyłając wiele testów numbers with your ViewState trying to find your hash key.

The IP you give have a big list of activity the last few days.

Alternatywą, która może powodować ten błąd, jest zerwanie elementu ViewState. Możesz mieć compress it and split it, jeśli masz zbyt dużą wartość ViewState. Możesz również disable all the controls that not needed. Możesz również dodać log to see from inside what's is going on right on a base page.

Answer 2

tak to działa na mnie zbyt

tutaj w vbnet

Compressor.vb

Imports System.IO 
Imports System.IO.Compression 
Public Class Compressor 

Public Shared Function Compress(ByVal data() As Byte) As Byte() 
    Dim output As MemoryStream = New MemoryStream 
    Dim gzip As GZipStream = New GZipStream(output, CompressionMode.Compress, True) 
    gzip.Write(data, 0, data.Length) 
    gzip.Close() 
    Return output.ToArray 
End Function 

Public Shared Function Decompress(ByVal data() As Byte) As Byte() 
    Dim input As MemoryStream = New MemoryStream 
    input.Write(data, 0, data.Length) 
    input.Position = 0 
    Dim gzip As GZipStream = New GZipStream(input, CompressionMode.Decompress, True) 
    Dim output As MemoryStream = New MemoryStream 
    Dim buff() As Byte = New Byte((64) - 1) {} 
    Dim read As Integer = -1 
    read = gzip.Read(buff, 0, buff.Length) 

    While (read > 0) 
     output.Write(buff, 0, read) 
     read = gzip.Read(buff, 0, buff.Length) 

    End While 

    gzip.Close() 
    Return output.ToArray 
End Function 
End Class 

i to wklejeniu wewnątrz default.aspx potrzebuje

Imports System.IO

Protected Overrides Function LoadPageStateFromPersistenceMedium() As Object 
    Dim viewState As String = Request.Form("__VSTATE") 
    Dim bytes() As Byte = Convert.FromBase64String(viewState) 
    bytes = Compressor.Decompress(bytes) 
    Dim formatter As LosFormatter = New LosFormatter 
    Return formatter.Deserialize(Convert.ToBase64String(bytes)) 
End Function 

Protected Overrides Sub SavePageStateToPersistenceMedium(ByVal viewState As Object) 
    Dim formatter As LosFormatter = New LosFormatter 
    Dim writer As StringWriter = New StringWriter 
    formatter.Serialize(writer, viewState) 
    Dim viewStateString As String = writer.ToString 
    Dim bytes() As Byte = Convert.FromBase64String(viewStateString) 
    bytes = Compressor.Compress(bytes) 
    ClientScript.RegisterHiddenField("__VSTATE", Convert.ToBase64String(bytes)) 
End Sub
