python之如何抓取多个网站的缩略图截图

我有一个包含 2500 个网站的列表，需要抓取它们的缩略图。我该怎么做？

我可以尝试使用 Perl 或 Python 解析网站，Mechanize 会是一件好事。但我对 Perl 不是很熟悉。

请您参考如下方法:

这是 Perl 解决方案:

  use WWW::Mechanize::Firefox; 
  my $mech = WWW::Mechanize::Firefox->new(); 
  $mech->get('http://google.com'); 
 
  my $png = $mech->content_as_png(); 

来自文档:

Returns the given tab or the current page rendered as PNG image.

All parameters are optional. $tab defaults to the current tab. If the coordinates are given, that rectangle will be cut out. The coordinates should be a hash with the four usual entries, left,top,width,height.

This is specific to WWW::Mechanize::Firefox.

Currently, the data transfer between Firefox and Perl is done Base64-encoded. It would be beneficial to find what's necessary to make JSON handle binary data more gracefully.
