problems with 0x00 in string

4 posts in this topic

#1 ·  Posted (edited)

Good day!

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

$upfile = "picture.jpg";
if not FileExists($upfile) Then
    return -1
EndIf

$handle = FileOpen($upfile,16)
$fileread = ''

While 1
    $t = FileRead($handle, 1)
    If @error Then ExitLoop
    $fileread = StringToBinary($t)
    
WEnd

FileClose($handle)

$boundary = '----------Omt4atmtaOmNtmo'

$data = "--" & $boundary & @LF & _
    'Content-Disposition: form-data; name="method"' & @lf & @lf & 'post' & @lf & _
    "--" & $boundary & @lf & _
    'Content-Disposition: form-data; name="file"; filename="picture.jpg"' & @LF & _
    'Content-Type: image/pjpeg' & @LF & @LF & _
     $fileread & @lf & _
    '--'&$boundary&'--' & @lf& @lf
    
_WinHttpAddRequestHeaders($h_openRequest,"Accept-Encoding: identity")
_WinHttpAddRequestHeaders($h_openRequest,"Content-Type: multipart/form-data; boundary=" & $boundary)

_WinHttpSendRequest($h_openRequest,$WINHTTP_NO_ADDITIONAL_HEADERS, $WINHTTP_NO_REQUEST_DATA, StringLen($data), 0)

_WinHttpWriteData($h_openRequest, $data)

Can anyone show how to avoid this? Thanks!

You have to use _WinHttpWriteData with $iMode set to 1 I think.

Call me crazy, but the FileRead part of the script seems to make no sense:

I believe $t is already binary when read and the content of $fileread is constantly replaced with the binary representation of $t, instead of appending to it.

At the end of the loop $fileread will only have a binary representation of the (already binary representation) of the last byte of the file won't it?

Try to replace that part of your script with this instead:

$handle = FileOpen($upfile,16)
$fileread = FileRead($handle)
FileClose($handle)

For the binary upload I try ProgAndy's suggestion.

Thanx, ProgAndy)))

I'm idiot...

And yes, the FileReade code part was not right too...
