use LWP::Simple to get ftp site content in Perl

I am having some issue here using LWP::Simple to get ftp site content in Perl. It would work fine if the site used http, but not ftp, for example ftp://ftp.di.uminho.pt/pub/ctan/fonts/. But in my firefox browser, I can view the content as html.

So how 开发者_StackOverflow社区to get the html of the site in this case?


LWP returns a document of the type text/ftp-dir-listing for a FTP directory. Use File::Listing to parse it.

$ GET -USe ftp://ftp.di.uminho.pt/pub/ctan/fonts/
GET ftp://ftp.di.uminho.pt/pub/ctan/fonts/

You probably want to use Net::FTP instead:

use Net::FTP;

$ftp = Net::FTP->new("some.host.name", Debug => 0)
  or die "Cannot connect to some.host.name: $@";

$ftp->cwd("/pub")
  or die "Cannot change working directory ", $ftp->message;

$ftp->get("that.file")
  or die "get failed ", $ftp->message;

$ftp->quit;


Firefox will internally generate an HTML document when you are viewing an FTP directory. The FTP server won't provide one.

If you want one, then you will have to iterate over the files and directories and generate your own.
