Uploading files containing 0x00

[Krisser50]

Hey

I have a funktion to upload a file. The PHP script can't work with the file then the "0x00" char is stripped from the file... And when the "0x00" char is included the file won't even be uploaded...

Here is the function:

$boundary = "------"&Chr(Random(Asc("A"), Asc("Z"), 3))&Chr(Random(Asc("a"), Asc("z"), 3))&Chr(Random(Asc("A"), Asc("Z"), 3))&Chr(Random(Asc("a"), Asc("z"), 3))&Random(1, 9, 1)&Random(1, 9, 1)&Random(1, 9, 1)
    $oHTTP = ObjCreate("winhttp.winhttprequest.5.1")
    $oHTTP.Open("POST", "http://LINK REMOVED", False)
    $oHTTP.SetRequestHeader("User-Agent", "UploadProgram")
    $oHTTP.SetRequestHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")
    $oHTTP.SetRequestHeader("Accept-Encoding", "gzip, deflate")
    $oHTTP.SetRequestHeader("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7")
    $oHTTP.SetRequestHeader("Content-Type", "multipart/form-data; boundary=" & $boundary)
    $fileopen = FileOpen($torrent,16)
    $fileread=''
    While 1
        $t = FileRead($fileopen, 1)
        If @error Then ExitLoop
        If $t <> 0x00 Then $fileread &= BinaryToString($t)
    WEnd
    FileClose($fileopen)

    $data= "--" & $boundary & @LF & 'Content-Disposition: form-data; name="torrent"; filename="' & $torrent & '"' & @LF & 'Content-Type: application/x-bittorrent' & @LF& @LF & $fileread & @LF & "--" & $boundary & "--"
    Dim $datasize = StringLen($data)
    $oHTTP.SetRequestHeader("Host", "HOST REMOVED")
    $oHTTP.SetRequestHeader("Content-Length", $datasize)
    $oHTTP.SetRequestHeader("Pragma", "no-cache")

    $oHTTP.Send($data); & @CRLF & $data2)
    $oReceived = $oHTTP.ResponseText

When i remove "If $t <> 0x00 Then" from the code, the file won't even be uploaded

I hope someone can help... Thanks in advance

By the way... The PHP-script is working, just not with this program

I'm not familiar with the Http functions, but you shouldn't convert binary data which contains 0x0 to a string because 0x0 marks the end of a string. You need to send the data as binary data. That's my guess at least.

For more about nulls embedded in strings, see the last few posts in this thread.

Anyway, Martin is right that you definitely should handle your binary data as ... binary data.

Disclaimer: I'm not used either with Http COM.

So then i have to convert the string to binary??

I will try that Thanks

[Krisser50]

When i convert the file content to Binary, the file isn't uploaded...

Even if i insert: Content-Transfer-Encoding: binary

in the $data line so it looks like this:

$data= "--" & $boundary & @LF & 'Content-Disposition: form-data; name="torrent"; filename="' & $torrent & '"' & @LF & 'Content-Type: application/x-bittorrent' & @LF& 'Content-Transfer-Encoding: binary' & @LF& @LF & $fileread & @LF & "--" & $boundary & "--"

It just won't work :S
