[ASP通用类]替换远程文件为本地文件并保存远程文件

不知道这个是不是叫通用类呢?ASP基础知识没学扎实,不好意思





1、将下面的文本文件下载,并将.TXT改为.ASP,里面有具体设置方法

http://www.dongjidao.com/remote.txt

2、调用方法:

<!--#include file="remote.asp"-->

文章入库的地方改成下面的代码

CODE:
[Copy to clipboard]
If sSaveFileSelect=True Then
     Rs("Content")=ReplaceRemoteUrl(ArticleContent,sSaveFilePath,sFileExt)
    Else
     Rs("Content")=ArticleContent
End If

<% 
'添加资源时是否保存远程图片
Const sSaveFileSelect=True

'远程图片保存目录,结尾请不要加“/”
Const sSaveFilePath="/images/News"

'远程图片保存类型
Const sFileExt="jpg|gif|bmp|png"
