Hi,

I want to use LWP::Simple inside a safe compartment created with the Safe Module. But it ends up with errors like "Can't locate object method "new" via package "LWP::UserAgent" at line... or "Require trapped by operation mask..."

Here is how the code looks like (shortened ;-) ):

$codefromoutside='print wget "http://google.com";';

use LWP::Simple ();
sub wget { LWP::Simple::get $_[0] }

use Safe;
$safe=new Safe; $safe->share(qw(wget));

$safe->reval($codefromoutside);
print $@ if $@;
[download]

(There is a reason why I use "wget" instead of "get" directly because I have already a subroutine with the name "get" elsewhere)

I tried some other things but they all didn't work. Does anybody know how to use LWP::Simple::get inside a save compartment?

Thanks in advance,

best regards,

Christoph Bergmann

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).
Want more info? How to link or How to display code and escape characters are good places to start.
