如何在 Java 中下载完整的网页（及其所有内容）？

Question

Using Java, I need to save a complete webpage(with all its contents like images, css, javascript etc) like how we can do with save as-->complete webpage option with HttpClient lib. How can I do this?

Answer 1

You can try lib curl java http://curl.haxx.se/libcurl/java/

And you can refer to this discussion also curl-equivalent-in-java

Answer 2

您必须编写一个应用程序来获取 html 文件，解析它并提取所有引用，然后获取通过解析找到的所有文件。

Answer 3

It's not so easy because some CSS/JS/Images files paths might be "hidden". Just consider the following example:

<script type="...">
   document.write("&bla;script" + " type='...' src='" + blahBlah() + "'&bla;" + "&bla;/script&bla;");
</script>

However, fetching page source, parsing in the search for URLs and downloading founded URLs is pretty everything you'll probably need.
