Hello everyone I really tried to fix this problem but this time I need his help.
This code work to download a file with little size:
use strict;
use warnings;
use Plack::Response;
use Path::Tiny;
use File::MimeInfo;
sub return_psgi {
my $self = shift;
my $path_file = shift;
my $content_type = mimetype($path_file);
$content_type = 'application/octet-stream' if not defined $content
+_type;
my $content = path($path_file);
my $content_download = $content->slurp;
require File::Spec::Unix;
my $basename = $path_file;
$basename =~ s|\\|/|g;
$basename = ( File::Spec::Unix->splitpath($basename) )[2];
$basename =~ s|[^\w\.-]+|_|g;
my $response = Plack::Response->new(200);
$response->headers(
[
'Content-Type' => $content_type,
'Content-Disposition' => qq[attachment; filename="$basename
+"],
],
);
$response->body($content_download);
return $response->finalize;
}
But I want to download big files greater of 1GB, so change to download in chunks, to this code:
open (FILE, "< $path_file") or die "can't open $path_file: $!";
binmode FILE;
local $/ = \102400;
while (<FILE>) {
my $var = scalar $_;
$response->body($var);
return $response->finalize;
}
close FILE;
Another intent, using autoflush:
use IO::Handle;
my $BLOCK_SIZE = 1024 * 1024;
open(my $fh, "<:raw", $path_file) or die "Can't read from input file $
+path_file $!\n";
while (read($fh, $buffer, $BLOCK_SIZE)) {
$response->body($buffer);
$fh->autoflush;
}
close $fh;
return $response->finalize;
The 2 previous intentions download file a size of kb, corrupt file.
can you please tell me where is my error in my code?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
