Question

Web sitem aşağıda istisnalar her gün düzenliyor ve ben çözüm bulamadım. i web kaç araştırma yaptım ve bu şimdiye kadar ne olduğunu. aspx'e aşağıdaki seçeneği eklemek sorunu çözmeyecektir.

ValidateRequest = "false" EnableEventValidation = "false" viewStateEncryptionMode

Ayrıca

UPDATE i renkli http://www.codeproject.com/Articles/14733/ViewState-Compression

alttan ViewState sıkıştırarak hata tespit ve değiştirme, bir baz-64 karakter dizisi hata için geçersiz uzunluğu sabit bununla orijinal yöntem. Yardım için

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)); 
    } 

herkese teşekkürler :)

Answer 1

Bunu ancak söylemek üzgünüm siteniz şey yoktu ve en kısa sürede EventValidations yeniden etkinleştirmeniz gerekir.

Gördükleriniz birçok testi numbers with your ViewState trying to find your hash key göndererek an attempt to hack your site olduğunu.

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

Şimdi, bu hataya neden olan alternatif ViewState'in kırılmasıdır. Eğer çok büyük ViewState varsa compress it and split it edebilirsiniz. Ayrıca disable all the controls that not needed da olabilir. Ayrıca bir log to see from inside what's is going on right on a base page ekleyebilirsiniz.

evet VBNet burada

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 

çok benim için çalışıyor ve bu onu

Imports System.IO ihtiyacı default.aspx içine yapıştırın

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
