长期以来，我一直在尝试使用 python(2.4) 解析和运行 javascript 网页。不幸的是我不能使用 qt,webkit 所以大多数基于 python 的 headless 浏览器被排除在外。然而，我最近在 perl(使用 perl 5.8.8)中发现了 WWW::Scripter，它似乎也是 javascript 的脚本引擎。我还安装了运行它所需的 javascript 插件。
use WWW::Scripter;
$w = new WWW::Scripter;
$w->use_plugin('JavaScript'); # packaged separately
$w->get('some javascript website');
print $w->content;
好吧，它会打印出很多错误并最终终止，并且输出似乎与预期的不符。我尝试了 3-4 个站点，但结果相同。我所说的预期输出是指源代码，可以从 google chrome 浏览器的检查元素中看到。 知道我在使用 perl 脚本程序时做错了什么吗？其次，任何快速替代方法都可以让 javascript 引擎运行以解析 python2.4 或 perl 中的网站(甚至是 ruby，约束不能使用 qt) 希望我能在不引起混淆的情况下提出我的问题。

谢谢
请您参考如下方法:
如果它可能有任何用处:jsPhantom是一个单个文件 headless webkit(无需安装)。我用了好几次(只是把 exe 放在 perl 旁边)，然后让它开始工作。下一版本 (1.9)(3 月/4 月？)预计将处理标准输入以简化管道。
