How Upload file using Mojolicious?

(First, you need some HTML form with method="post" and enctype="multipart/form-data", and a input type="file" with name="upload". Just to be sure.)

If there were no errors, $fileuploaded would be a Mojo::Upload. Then you could check its size, its headers, you could slurp it or move it, with $fileuploaded->move_to('path/file.ext').

Taken from a strange example.

To process uploading files you should use $c->req->uploads

post '/' => sub {
   my $c = shift;
   my @files;
   for my $file (@{$c->req->uploads('files')}) {
     my $size = $file->size;
     my $name = $file->filename;

     push @files, "$name ($size)";
     $file->move_to("C:\\Program Files\\Apache Software Foundation\\Apache24\\htdocs\\ProcessingFolder\\".$name);
   }
   $c->render(text => "@files");
} => 'save';
