如何利用asp来打包网站
一、遇到的权限问题。 我们在打包网站的时候经常会遇到权限问题。因为现在的虚拟主机的安全性不断的在提高,很多虚拟主机都禁用了WScript.shell。因为这个对象可以执行一些cmd命令,对虚拟主机的安全具有很大的威胁。记得前几年我在学习网络安全的时候,通过一些漏洞获得了网站的weshell后很多的虚拟主机都可以执行cmd命令,例如webshell中执行netstat -na 来查看服务器端口。可是现在由于虚拟空间销售商安全意识的提高,大多数的虚拟主机都禁用了wscript.shell。为什么要提到wscript.shell呢?因为我记得那时候程序打包利用的是rar,dos下的rar来压缩整个网站,而rar需要执行dos命令也就是利用wscript.shell来执行cmd命令。
二、 禁用了wscript.shell怎么办呢?
我最近就遇到了这样一个问题,其他网络公司的一个客户想把自己的网站(某净化工程公司)转移到我们公司来维护,但是由于网络公司拒绝提供网站的ftp,如何拿到这个网站的源代码呢,只有获得这个网站的webshell的情况下才可以拿到源代码。这个过程很简单,我给客户要了后台地址、账号和密码,进入后台后利用了一个简单的上传漏洞轻松的拿下了网站的webshell。在拿下网站权限后最后的工作是打包整个网站。问题却出现了,在没有ftp的情况下要想下载整个网站,手工一个一个文件的去下载是相当麻烦的。我发现webshell里面有个打包网站的功能,索性试了一下,但结果令我比较失望,通过检查是代码有些问题,经过修正顺利的完成了任务。分析了一下网站打包部分的功能代码,并加以修改做成了一个具有打包,解包功能的asp程序代码如下:

三、利用数据库可以存储二进制的办法打包网站
原理:通过建立一个access数据库,并在数据库中加入一个表。这个表有三个字段,一个是递增字段,一个字段来存放文件的路径,另一个字段来存放文件的二进制数据。我们知道有的时候需要在数据库中存放图片。同样我们可以在数据库中存放其他的数据。在压缩的时候吧文件的路径和文件都添加到数据库中,那么最后得到的就只是一个数据库文件。同样我们可以在数据库中利用查询语句获取二进制数据,在利用adodb.stream对象的SaveToFile方法存储为文件。
代码重点:
1.创建数据库
Set adoCatalog = Server.CreateObject("ADOX.Catalog")
C &Server.MapPath("HYTop.mdb")
adoCatalog.Create ConnStr
2.创建表
Conn.Execute("Create Table FileData(Id int IDENTITY(0,1) Primary Key Clustered, thePath VarChar, fileContent Image)")
3.CreateFolder 函数用来创建文件夹
4.文件如何插入到数据库中
Stream.LoadFromFile(Item.Path)
Rs("fileContent") = Stream.Read()
5.数据库中二进制保存为文件
Stream.Open
Stream.Type = 1
Stream.SetEos()
Stream.Write Rs("fileContent")
Stream.SaveToFile Str &Rs("thePath") , 2
四、需要的权限与组件
1.组件
ADOX.Catalog
Scripting.FileSystemObject (FSO)
Adodb.Stream
2.权限
能够创建文件夹
