wget下载整个网站的方法

转自: http://blog.itpub.net/29867/viewspace-716088/ 

(修改部分内容)

wget --restrict-file-name=ascii -m -c -nv -np -k -E -p http://www.w3school.com.cn/
wget --restrict-file-name=ascii -m -c -nv -np -k -E -p http://scrapy-chs.readthedocs.org

参数释义如下:

--restrict-file-name=ascii ,将文件名保存为ASCII格式。这样能避免utf-8文件名带来的麻烦(注:1.12版才支持ascii参数值)

-m 整站下载,mirror的缩写,是-N -r -l inf --no-remove-listing 这几个参数的快捷方式,具体详阅各自的说明

-c 续传

-nv 不显示详细的下载详情

-np don’t ascend to the parent directory.即下载的Web页面不越过后面指定的 http://www.xxx.com的范围。当然,如果你指定的是 http://www.xxx.com/aaa,则所有的web页面都要在 http://www.xxx.com/aaa下

-k 下载完成后,将页面文件中的链接转换为本地链接,便于离线浏览和制作chm等

-E 保存html/css文件时,使用合适的文件后缀。例如,在某些网站有些文件是服务器端动态生成的,虽然是css文件,但后缀并不是css,-E选项可以调整之

-p -np对页面文件做了限制,如果不加-p,则html所需的媒体文件也会受限于-np,-p则会下载html/css文件所需的所有媒体文件(图片、音频、视频等)

-R 拒绝下载的文件后缀列表,逗号分隔

 

至于下载到的文件的文件名变为了形如%A7这样百分号加16进制数字的形式,可以用个python程序来改变文件名:
