默认下载路径 %HOMEPATH%\AppData\Local\VirtualStore
一、下载与安装
1.1 下载
文件名：wget-1.11.4-1-setup.exe
官网：https://www.gnu.org/software/wget/
下载地址：https://www.gnu.org/software/wget/faq.html#download
windows: https://eternallybored.org/misc/wget/
1.2 安装
双击即可安装，安装到目录：D:\安装的软件\GnuWin32-Wget。
二、使用
DOS下，切换到目录：D:\安装的软件\GnuWin32-Wget\bin。
wget -S www.baidu.com --referer=m.baidu.com
-S 输出服务器的返回信息。
--referer 执行数据包中的referer。
三、修改环境变量
右键计算机 -> 属性 -> 高级系统设置 -> 环境变量 -> 系统变量(S)
3.1 新建环境变量
GNU_HOME=D:\安装的软件\GnuWin32-Wget
3.2 编辑添加path
PATH=...;;%GNU_HOME%\bin
...代表之前的路径，不变
修改环境变量后，打开DOS，可以再任何窗口下执行wget了。
