Fetching data from YouTube using Perl
As I am trying to follow how my screencasts are doing on YouTube I keep visiting the web site checking out the number of subscribers and the number of views of the videos. It's getting a bit boring so I thought I should automate it.
I started by installing the Padre on Strawberry Perl for Windows package but it would work on any other distribution of Perl, and on any other operating system.
cpan> install WebService::GData
After brief reading of the docs, and some copy-pasting I got this script:
#!/usr/bin/perl use 5.010; use strict; use warnings; use WebService::GData::YouTube; my $yt = WebService::GData::YouTube->new(); my $p = $yt->get_user_profile('gabor529'); say $p->about_me; my $s = $p->statistics; say $s->view_count; say $s->subscriber_count; #say $s->video_watch_count; say $s->total_upload_views;
This would fetch my user profile - without even logging in to YouTube - and print out the statistics. I have 105 subscribers, when I prepared the screencast in June 2011. There are 551 in July 2014.
Then I wanted to send the resulting data to myself via Gmail. Another short search on Meta CPAN for Gmail and I found Email::Send::SMTP::Gmail. Some more copy pasting and here is the script that would send an e-mail using my gmail-account to myself. I guess I could use the same code to send to anyone else as well.
use Email::Send::SMTP::Gmail; my $mail=Email::Send::SMTP::Gmail->new( -smtp=>'gmail.com', -login=>'firstname.lastname@example.org', -pass=>'google and me'); my $text = ''; $text .= "view count " . $s->view_count . "\n"; $text .= "subscribers " . $s->subscriber_count . "\n"; $text .= "total views" . $s->total_upload_views . "\n"; $mail->send(-to=>'email@example.com', -subject=>'youtube update', -verbose=>'1', -body=> $text, # -attachments=>'full_path_to_file' ); $mail->bye;
That was all of it. It took me almost 15 minutes to write this! (And 3 more hours to prepare the screencast.
ps. That is not really my e-mail address. I was just using it for this demo.
