Net::FTP Error Handling

When a Net::FTP operation fails, you really want to get the error details so you know what failed. It always takes me a while to find the details in the Net::FTP docs so I thought I'd post here:

Initial Connection: the connection is established when you create the object. If the connect fails, new() will return undef and the error message will be in $@:

my $ftp = Net::FTP->new($destserv) ||
  die "Connect to $destserv failed: $@";
[download]

Commands: if a command fails, the method return value will be undef. The error message can be accessed using the 'message()' method. If you're checking for a particular message, you might be better off using the 'code()' method to get the three digit FTP protocol status code which preceded the message:

$ftp->get($file) ||
  die "get($file) failed: " . $ftp->code() . ": " . $ftp->message();
[download]

Re: Net::FTP pwd bug? by mikeock (Hermit) on Oct 12, 2005 at 19:05 UTC
When using this module. I cannot get the pwd command to work. I am connected to an ftp server and am trying to use `$ftp->pwd()` and I get nothing in return. Is this dumping to a default variable that I am missing or is this really a bug?	[reply] [d/l]

Hi, If you are following the above code try something like : `#!/usr/bin/perl use Net::FTP; my $destserv="ftp.myhost.com"; my $destuser="username"; my $destpass="password"; $ftp = Net::FTP->new($destserv) or die "error connecting\n"; $ftp->login($destuser,$destpass); my $mypath = $ftp->pwd(); $ftp->quit(); print "FTP Path: $mypath";` [download] Keep in mind that this is untested, its late and I am seriously sleep deprived. Have you checked out the documentation? There is a link to examples you can also have a look at. Hope this helps Martin	[reply] [d/l]

When that variable is added `my $mypath = $ftp->pwd():` to my code, I get the same results as just trying to call `$ftp->pwd();` And by the same I mean that there is no repsonse at all. The Box that has the server on it allows me to login and type pwd so I know that it is supported on the server.	[reply] [d/l] [select]
