Hello Monks,

I posted here a couple of weeks ago about a problem that I was having writing a simple web-scraping programme that scraped comments from the website Reddit, and allowed me to analyse them using computational linguistics methods.

Following the very helpful advice of the forum members here, I revised my code and switched from using LWP::Simple to Mojo:UserAgent.

The following code does almost exactly what I need it do (i.e. it downloads the comments and stores them in a way that is readable for my corpus software.

use Mojo::UserAgent;

my $url ='https://www.reddit.com/r/unitedkingdom/comments/58m2hs/i_dan
+ie+l_blake_is_released_today/.json';

my $ua = Mojo::UserAgent->new;
my $data = $ua->get( $url )->res->json;



foreach my $comment ( @{$data} ) {
    foreach my $child ( @{ $comment->{'data'}->{'children'} } ) {
    #output path needs changing
        open(OUT, ">>C:/Users/user/perl_tests/redresults221.txt");
        my $yprint = $child->{'data'}->{'body'} . "\n" if( $child->{'d
+ata'}->{'body'} );
        print OUT "$yprint";
        close(OUT); 

    }
}

However, I need to add two more elements to the code:

1) I need it to work so that it downloads multiple URLs either by a) letting me make a list of URLs to download within the code (e.g. through some kind of  my @URLS = command) or b) the code itself can go into a separate .txt file containing the URL's that I am interested in and then run the existing code upon them (if that makes sense!?!)

2) I need to put a delay or sleep element in the code so that my IP address does not get flagged by the site. In my original programme I used the command  sleep(int(rand(30))); should this still work with the Mojo:UserAgent library?

Thanks in advance for your help, it is really appreciated. What you guys do for us beginners is pretty extraordinary!

EDIT: In my original post I should have made it clear that the code that I posted was very kindly written by marto, I never meant to imply that I had wriiten it myself, but I can understand that my wording was very careless.

I now have a working code for my problem, based on three codes that were generously written for me by marto, Athanasius and stevieb:

use Mojo::UserAgent;

my @urls = qw(
    https://www.example1.com.json
        https://www.example2.com.json
    https://www.example3.com.json
);

for my $URL (@urls){
    my $ua = Mojo::UserAgent->new;
    my $data = $ua->get( $URL )->res->json;

sleep(int(rand(60)));

foreach my $comment ( @{$data} ) {
    foreach my $child ( @{ $comment->{'data'}->{'children'} } ) {
    #output path needs changing
        open(OUT, ">>C:/Users/user/perl_tests/redresults805.txt");
        my $yprint = $child->{'data'}->{'body'} . "\n" if( $child->{'d
+ata'}->{'body'} );
        print OUT "$yprint";
        close(OUT); 

    }
}
}
