Ciao a tutti,
sono un nuovo iscritto e vorrei fare i complimenti a tutti per questo magnifico sito e per la disponibilità di tutti gli iscritti.
Ho un piccolo problemino con un sito web che permette l'upload dei file via http.
Tale sito si trova su Windows Server 2003 con SP2 ed è composto dalla seguente pagina htm (default.asp)
<form method="POST" enctype="multipart/form-data" action="upload1.asp">
<p align="center"><font color="#000080" size="2" face="Arial">
File: </font><input type="file" name="blob" size=30>
<input type="submit" name="Enter" value="Aggiungi">
</form>
Ecco il codice della pagina upload1.asp:
'variabili di configurazione
Dim folder
'directory sul server con accesso in scrittura
folder = "documenti"
'fine variabili di configurazione
Response.Expires=0
Response.Buffer = TRUE
Response.Clear
Sub BuildUploadRequest(RequestBin)
PosBeg = 1
PosEnd = InstrB(PosBeg,RequestBin,getByteString(chr(13)))
boundary = MidB(RequestBin,PosBeg,PosEnd-PosBeg)
boundaryPos = InstrB(1,RequestBin,boundary)
Do until (boundaryPos=InstrB(RequestBin,boundary & getByteString("--")))
Dim UploadControl
Set UploadControl = CreateObject("Scripting.Dictionary")
'Get an object name
Pos = InstrB(BoundaryPos,RequestBin,getByteString("Conte nt-Disposition"))
Pos = InstrB(Pos,RequestBin,getByteString("name="))
PosBeg = Pos+6
PosEnd = InstrB(PosBeg,RequestBin,getByteString(chr(34)))
Name = getString(MidB(RequestBin,PosBeg,PosEnd-PosBeg))
PosFile = InstrB(BoundaryPos,RequestBin,getByteString("filen ame="))
PosBound = InstrB(PosEnd,RequestBin,boundary)
If PosFile<>0 AND (PosFile<PosBound) Then
PosBeg = PosFile + 10
PosEnd = InstrB(PosBeg,RequestBin,getByteString(chr(34)))
FileName = getString(MidB(RequestBin,PosBeg,PosEnd-PosBeg))
UploadControl.Add "FileName", FileName
Pos = InstrB(PosEnd,RequestBin,getByteString("Content-Type:"))
PosBeg = Pos+14
PosEnd = InstrB(PosBeg,RequestBin,getByteString(chr(13)))
ContentType = getString(MidB(RequestBin,PosBeg,PosEnd-PosBeg))
UploadControl.Add "ContentType",ContentType
PosBeg = PosEnd+4
PosEnd = InstrB(PosBeg,RequestBin,boundary)-2
Value = MidB(RequestBin,PosBeg,PosEnd-PosBeg)
Else
Pos = InstrB(Pos,RequestBin,getByteString(chr(13)))
PosBeg = Pos+4
PosEnd = InstrB(PosBeg,RequestBin,boundary)-2
Value = getString(MidB(RequestBin,PosBeg,PosEnd-PosBeg))
End If
UploadControl.Add "Value" , Value
UploadRequest.Add name, UploadControl
BoundaryPos=InstrB(BoundaryPos+LenB(boundary),Requ estBin,boundary)
Loop
End Sub
Function getByteString(StringStr)
For i = 1 to Len(StringStr)
char = Mid(StringStr,i,1)
getByteString = getByteString & chrB(AscB(char))
Next
End Function
Function getString(StringBin)
getString =""
For intCount = 1 to LenB(StringBin)
getString = getString & chr(AscB(MidB(StringBin,intCount,1)))
Next
End Function
byteCount = Request.TotalBytes
RequestBin = Request.BinaryRead(byteCount)
Dim UploadRequest
Set UploadRequest = CreateObject("Scripting.Dictionary")
BuildUploadRequest RequestBin
contentType = UploadRequest.Item("blob").Item("ContentType")
filepathname = UploadRequest.Item("blob").Item("FileName")
filename = Right(filepathname,Len(filepathname)-InstrRev(filepathname,"\"))
value = UploadRequest.Item("blob").Item("Value")
'Create FileSytemObject Component
Set ScriptObject = Server.CreateObject("Scripting.FileSystemObject")
'Create and Write to a File
Set MyFile = ScriptObject.CreateTextFile(Server.mappath(folder) &"\"&filename)
For i = 1 to LenB(value)
MyFile.Write chr(AscB(MidB(value,i,1)))
Next
MyFile.Close
Ho il seguente messaggio d'errore:
Oggetto Request error 'ASP 0104 : 80004005'
Operazione non consentita
alla riga "RequestBin = Request.BinaryRead(byteCount)"
Ho controllato i permessi di scrittura sulla cartella documenti e sono corretti...
cosa potrebbe essere? non so come fare...
grazie per l'aiuto
Nicola
