asp下实现替换远程文件为本地文件并保存远程文件的代码
1、将下面的文本文件下载,并将.TXT改为remote.asp,里面有具体设置方法
代码如下:
<%
'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"
'/////////////////////////////////////////////////////
'作 用:替换字符串中的远程文件为本地文件并保存远程文件
'参 数:
' sHTML : 要替换的字符串
' sSavePath : 保存文件的路径
' sExt : 执行替换的扩展名
Function ReplaceRemoteUrl(sHTML, sSaveFilePath, sFileExt)
Dim s_Content
s_Content = sHTML
If IsObjInstalled("Microsoft.XMLHTTP") = False then
ReplaceRemoteUrl = s_Content
Exit Function
End If
Dim re, RemoteFile, RemoteFileurl,SaveFileName,SaveFileType,arrSaveFileNameS,arrSaveFileName,sSaveFilePaths
Set re = new RegExp
re.IgnoreCase = True
re.Global = True
re.Pattern = "((http|https|ftp|rtsp|mms):(\/\/|\\\\){1}((\w)+[.]){1,}(net|com|cn|org|cc|tv|[0-9]{1,3})(\S*\/)((\S)+[.]{1}(" & sFileExt & ")))"
Set RemoteFile = re.Execute(s_Content)
For Each RemoteFileurl in RemoteFile
SaveFileType = Replace(Replace(RemoteFileurl,"/", "a"), ":", "a")
arrSaveFileName = Right(SaveFileType,12)
sSaveFilePaths=sSaveFilePath & "/"
SaveFileName = sSaveFilePaths & arrSaveFileName
Call SaveRemoteFile(SaveFileName, RemoteFileurl)
s_Content = Replace(s_Content,RemoteFileurl,SaveFileName)
Next
ReplaceRemoteUrl = s_Content
End Function
'////////////////////////////////////////
'作 用:保存远程的文件到本地
'参 数:LocalFileName ------ 本地文件名
' RemoteFileUrl ------ 远程文件URL
'返回值:True ----成功
' False ----失败
Sub SaveRemoteFile(s_LocalFileName,s_RemoteFileUrl)
Dim Ads, Retrieval, GetRemoteData
On Error Resume Next
Set Retrieval = Server.CreateObject("Microsoft.XMLHTTP")
With Retrieval
.Open "Get", s_RemoteFileUrl, False, "", ""
.Send
GetRemoteData = .ResponseBody
End With
Set Retrieval = Nothing
Set Ads = Server.CreateObject("Adodb.Stream")
With Ads
.Type = 1
.Open
.Write GetRemoteData
.SaveToFile Server.MapPath(s_LocalFileName), 2
.Cancel()
.Close()
End With
Set Ads=nothing
End Sub
'////////////////////////////////////////
'作 用:检查组件是否已经安装
'参 数:strClassString ----组件名
'返回值:True ----已经安装
' False ----没有安装
Function IsObjInstalled(s_ClassString)
On Error Resume Next
IsObjInstalled = False
Err = 0
Dim xTestObj
Set xTestObj = Server.CreateObject(s_ClassString)
If 0 = Err Then IsObjInstalled = True
Set xTestObj = Nothing
Err = 0
End Function
%>
2、调用方法:
<!--#include file="remote.asp"-->
If sSaveFileSelect=True Then
Rs("Content")=ReplaceRemoteUrl(ArticleContent,sSaveFilePath,sFileExt)
Else
Rs("Content")=ArticleContent
End If
