ASP替换、保存远程图片实现代码

ASP通过函数来实现替换、保存远程图片，完成自动采集图片、提取图片的功能，函数中自动判断重复图片，智能分析链接路径，并转成成相对的图片地址保存在你指定的网站目录中，我们可将此函数用在后台的编辑器中，当你复制了含有图片的内容后，本代码会自动帮你上传图片。同时本代码也是采集程序中的重要处理函数，函数代码如下：

Function ReplaceSaveRemoteFile(ConStr,strInstallDir,strChannelDir,SaveTf,TistUrl)
If ConStr="$False$" or ConStr="" or strInstallDir="" or strChannelDir="" Then
ReplaceSaveRemoteFile=ConStr
Exit Function
End If
Dim TempStr,TempStr2,TempStr3,Re,Matches,Match,Tempi,TempArray,TempArray2
Set Re = New Regexp
Re.IgnoreCase = True
Re.Global = True
Re.Pattern ="]>"
Set Matches =Re.Execute(ConStr)
For Each Match in Matches
If TempStr<>"" then
TempStr=TempStr & "$Array$" & Match.Value
Else
TempStr=Match.Value
End if
Next
If TempStr<>"" Then
TempArray=Split(TempStr,"$Array$")
TempStr=""
For Tempi=0 To Ubound(TempArray)
Re.Pattern ="src\s*=\s*.+?\.(gif|jpg|bmp|jpeg|psd|png|svg|dxf|wmf|tiff)"
Set Matches =Re.Execute(TempArray(Tempi))
For Each Match in Matches
If TempStr<>"" then
TempStr=TempStr & "$Array$" & Match.Value
Else
TempStr=Match.Value
End if
Next
Next
End if

Re.Pattern ="src\s*=\s*"
TempStr=Re.Replace(TempStr,"")
End If

函数参数说明：
ConStr：要替换的字符串
参 数：SaveTf：是否保存文件，False不保存，True保存
参 数: TistUrl：当前网页地址
