vbs结合wget 实现下载网站图片
vbs 函数过程:
1. 调用wget: 下载网站所有页面到本脚本目录 ……
2. 扫描本脚本目录中所有文件 ……
3. 读取本脚本目录中的所有网页,匹配图片 URL 地址 ……
4. 保存所有图片 URL 地址到 url-img.txt 文件 ……
5. 调用wget: 下载 url-img.txt 指定的图片到本脚本 img 目录 ……

提示:
1. 警告:请不要直接运行代码,这里的示范网址可能无法访问、或缺乏安全性,请改为其他网址再使用。
2. 请将 wget.exe 放置于脚本同一目录下,然后执行。文件结构如下:
..\wget.exe
..\wget_img.vbs
..\findstr_html.vbs
