Is it possible to write a script in Perl that opens different URLs and saves a screenshot of each of them?

推荐答案

你可以使用 WWW::Mechanize::Firefox 控制 Firefox 实例并使用 $mech->content_as_png 转储呈现的页面.

You could use WWW::Mechanize::Firefox to control a Firefox instance and dump the rendered page with $mech->content_as_png.

请注意，设置它可能会带来相当大的挑战.

Be aware that setting it up can pose quite a challenge, though.

如果一切正常，您可以简单地使用这样的脚本来转储所需网站的图像，但您应该启动 Firefox 并手动将其调整为所需的宽度(高度无关紧要，WWW::Mechanize::Firefox 总是转储整个页面).

If all works as expected, you can simply use a script like this to dump images of the desired websites, but you should start Firefox and resize it to the desired width manually (height doesn't matter, WWW::Mechanize::Firefox always dumps the whole page).

use WWW::Mechanize::Firefox;
use Path::Class qw/file/;

my $mech = WWW::Mechanize::Firefox->new(
  bufsize => 10_000_000, # PNGs might become huge
);
$mech->get('http://www.stackoverflow.com/');

my $fh = file( 'test.png' )->open( '> :raw' );
print $fh $mech->content_as_png();
