百度空间备份脚本baidublogbak.vbs代码分析

'用法示例：
'cscript bak.vbs 百度用户名 第I页 至第n页 目录列表.htm 用户名 密码
'例如我的blgo示例：
'cscript baidublogbak.vbs myvbscript 0 3 url.htm myvbscript mima
'表示从第0页备份到第3页，blog的共有页数打开http://hi.baidu.com/用户名/blog/index/0就可以看到了。url.htm存放的是目录列表
'注意的是百度是从0页计数的
'如果用户名和密码随便写也可以备份，但是无法备份私有文档
'推荐几页几页备份，最好建单独一个目录将bak.vbs放进去，会在当前目录生成mht文档。因为有的网络原因，有的无法成mht，请对照url.htm目录列表检查
