How can I use cURL or Wget inside of a Perl program?

Question

I am trying to download and output to a file using cURL in a Perl script.

1) I have to pass username and password in the following below. What switch should I use?

2) When I execute Perl script, this is what I get:

Can't locate WWW/Curl.pm in @INC (@INC contains: f:/Perl/site/lib f:/Perl/lib .)
 at onesec.pl line 9.
BEGIN failed--compilation aborted at haroldonesec.pl line 9.

use WWW::Curl;
curl http://download2.emu-lochard.com/sfo1/gru?start-time=2009-08-15+00%3A00%3A00&end-time=2009-08-15+12%3A59%3A59&time-zone=GMT&metric=laeq --data --O curllaeq.txt

3) How can I use Wget to do the same?

I am using the following but getting errors:

use LWP::Simple;
wget --user=username --password=password http://download2.emu-lochard.com/sfo1/gru?start-time=2009-08-15+00%3A00%3A00&end-time=2009-08-15+12%3A59%3A59&time-zone=GMT&metric=laeq -O laeq.txt

Answer 1

As Chris Lutz points out, you do not have WWW::Curl installed.

However, even if you did, it would not matter because the way you have tried to use the library seems completely unrelated to how the module should be used.

You should try reading the documentation for WWW::Curl and LWP::Simple.

Or, if this is all you need to do, I would use the command line utilities cURL or wget.

Answer 2

Not to repeat the obvious (you don't have the WWW::Curl installed) but to address the other issue, the standard accepted way to pass htaccess user/passwords is just accessing the url like this:

http://username:[email protected]/bla.file

Curl, wget, and every other sensible program should be able to handle this form.
