Uploading files containing 0x00

5 posts in this topic

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 :P

I hope someone can help... Thanks in advance :mellow:

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

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.

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

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.

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
