Send headers

[eagle00789]

i'm trying to send the following headers to get a file download active.

Content-Type: application/octet-stream
Content-Disposition: attachment; filename=<filename>
GET <location of file on server including file name> HTTP/1.1
Host: <server>
User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; MEGAUPLOAD 2.0; Alexa Toolbar)
Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5
Accept-Language: en-en,en;q=0.5
Accept-Charset: windows-1251,utf-8;q=0.7,*;q=0.7
Pragma: no-cache
Cache-Control: no-chache
Authorization: Basic <password>

 

i'm trying to do that with the following code:

$handle=fopen("files/".$_POST['FileName'], 'r');
while (!feof($handle)) {
$data .= fgets($handle);
}
$data = str_replace("\r\n", "", $data);
header($data);

this works, except the download doesn't start. where have i gone wrong?

You have request and response headers there.  Your server shouldn't be sending a GET header, or a User-Agent header, or any of the Accept headers.  Nor should it be sending an Authorization: line with a password.  With that said, your client shouldn't be sending, Content-type, Content-disposition, Pragma or Cache-Control to the server.  What exactly are these headers for?

i'm trying to start a download from a remote server. that server requires authentication. i found the method i currently use on another forum (archive of that forum to be exactly, as the forum itself doesn't exists anymore)

If you are trying to just get a file from a remote server, try something such as this:

 

$socket = fsockopen('remoteserver.com', 80, $errno, $errstr, 15);
if (!$socket)
{
    print "Socket Error [#" . $errno . "]: " . $errstr;
}
else
{
    $out = "GET /filename.zip HTTP/1.1\r\n";
    $out = "Host: remoteserver.com\r\n";
    $out = "Connection: close\r\n\r\n";
    fwrite($socket, $out);
    $file = '';
    while (!feof($socket))
    {
        $file .= fgets($socket, 128);
    }
    fclose($socket);
    // At this point, $file now contains the file contents
}

and how do i send the $file to the client without saving the file first to the server??

and what about my authorization on that server??

Sorry, forgot about those things, here you go:

 

$socket = fsockopen('remoteserver.com', 80, $errno, $errstr, 15);
if (!$socket)
{
    print "Socket Error [#" . $errno . "]: " . $errstr;
}
else
{
    $out = "GET /filename.zip HTTP/1.1\r\n";
    $out .= "Host: remoteserver.com\r\n";
    $out .= "Authorization: BASIC " . base64_encode('username:password') . "\r\n";
    $out .= "Connection: close\r\n\r\n";
    fwrite($socket, $out);
    $file = '';
    while (!feof($socket))
    {
        $file .= fgets($socket, 128);
    }
    fclose($socket);

    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename="filename.zip"');
    print $file;
}
