madison.sacd has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks, I am trying to send email with pdf file via catalyst::plugin::email module.
However, after I check the email and download the attatched pdf file, I just got "file damaged" message.
I am sure the original pdf file can be opened normally.
Please help me to find what is wrong with my code. Thanks! 
    my @parts = (
        Email::MIME->create(
            attributes => {
              content_type => 'application/pdf',
              encoding     => 'quoted-printable',
              name         => 'document.pdf',
            },
            body => io( 'document.pdf' )->all,
        ),
        Email::MIME->create(
            attributes => {
              content_type => "text/plain",
              disposition  => "attachment",
              charset      => "US-ASCII",
          },
          body => "Hello there!",
        ),
    );

    my $r = $c->email(
        header => [
            From    => 's4@student.tku.edu.au',
            To      => 's3@student.tku.edu.au',
            Subject => 'Hello!'
        ],
        parts  => [ @parts ],
    );

Re: email pdf file - file damaged

    I have my reservations about IO::All, especially once you move from a hardcoded filename to anything variable because it reopens the security hole that was fixed by introducing the three argument form of open. Additionally, my guess is that you're running all of this under Windows and that IO::All doesn't know about binmode. From delving into the code of IO::All::File and IO::All, maybe you could alleviate this by using

    body => io( 'document.pdf' )->binary(1)->all,

    but I would entirely stay away from IO::All for it heaps too much magic onto magic and relies on the undocumented assumptions made by Ingy.

      Thanks for the reply but after modify, I still couldn't open the attached pdf file. I am running this under fedora 6. Any other suggestion? BTW, If you entirely stay away from IO::All, what method would you call when you want to attach a file to email?

        I would maybe use File::Slurp::slurp or write my own file slurper:

        sub slurp {
    open my $fh, "<", $_[0]
        or die "Couldn't open '$_[0]' for reading: $!";
    binmode $fh;
    local $/;
    my $result = <>;
};

        Maybe your (Content-)Encoding of quoted-printable is inappropriate for the type of file you're sending? I would think a Content-Encoding that uses base64 would be better maybe, if Email::Simple supports such. But then, I use MIME::Lite for most of my mailing needs.
