ASP替换、保存远程图片实现代码
投稿:lijiao
这篇文章主要分享了ASP替换、保存远程图片的函数代码,需要的朋友可以参考下
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 If TempStr<>"" Then Re.Pattern ="src\s*=\s*" TempStr=Re.Replace(TempStr,"") End If Set Matches=nothing Set Re=nothing If TempStr="" or IsNull(TempStr)=True Then ReplaceSaveRemoteFile=ConStr Exit function End if TempStr=Replace(TempStr,"""","") TempStr=Replace(TempStr,"'","") TempStr=Replace(TempStr," ","") Dim RemoteFileurl,SavePath,PathTemp,DtNow,strFileName,strFileType,ArrSaveFileName,RanNum,Arr_Path DtNow=Now() If SaveTf=True then SavePath= strChannelDir & "/" & year(DtNow) & right("0" & month(DtNow),2) & "/" response.write "链接路径:" & savepath & "" Arr_Path=Split(SavePath,"/") PathTemp="" For Tempi=0 To Ubound(Arr_Path) If Tempi=0 Then PathTemp=Arr_Path(0) & "/" ElseIf Tempi=Ubound(Arr_Path) Then Exit For Else PathTemp=PathTemp & Arr_Path(Tempi) & "/" End If If CheckDir(PathTemp)=False Then If MakeNewsDir(PathTemp)=False Then SaveTf=False Exit For End If End If Next End If '去掉重复图片 TempArray=Split(TempStr,"$Array$") TempStr="" For Tempi=0 To Ubound(TempArray) If Instr(Lcase(TempStr),Lcase(TempArray(Tempi)))<1 Then TempStr=TempStr & "$Array$" & TempArray(Tempi) End If Next TempStr=Right(TempStr,Len(TempStr)-7) TempArray=Split(TempStr,"$Array$") '转换相对图片地址 TempStr="" For Tempi=0 To Ubound(TempArray) TempStr=TempStr & "$Array$" & DefiniteUrl(TempArray(Tempi),TistUrl) Next TempStr=Right(TempStr,Len(TempStr)-7) TempStr=Replace(TempStr,Chr(0),"") TempArray2=Split(TempStr,"$Array$") TempStr="" '图片替换/保存 Set Re = New Regexp Re.IgnoreCase = True Re.Global = True For Tempi=0 To Ubound(TempArray2) RemoteFileUrl=TempArray2(Tempi) If RemoteFileUrl<>"$False$" And SaveTf=True Then'保存图片 ArrSaveFileName = Split(RemoteFileurl,".") strFileType=Lcase(ArrSaveFileName(Ubound(ArrSaveFileName)))'文件类型 If strFileType="asp" or strFileType="asa" or strFileType="aspx" or strFileType="cer" or strFileType="cdx" or strFileType="exe" or strFileType="rar" or strFileType="zip" then UploadFiles="" ReplaceSaveRemoteFile=ConStr Exit Function End If Randomize RanNum=Int(900*Rnd)+100 strFileName = year(DtNow) & right("0" & month(DtNow),2) & right("0" & day(DtNow),2) & right("0" & hour(DtNow),2) & right("0" & minute(DtNow),2) & right("0" & second(DtNow),2) & ranNum & "." & strFileType Re.Pattern =TempArray(Tempi) If SaveRemoteFile(SavePath & strFileName,RemoteFileUrl)=True Then '******************************** PathTemp=SavePath & strFileName ConStr=Re.Replace(ConStr,PathTemp) Re.Pattern=strInstallDir & strChannelDir & "/" UploadFiles=UploadFiles & "|" & Re.Replace(SavePath &strFileName,"") Else PathTemp=RemoteFileUrl ConStr=Re.Replace(ConStr,PathTemp) 'UploadFiles=UploadFiles & "|" & RemoteFileUrl End If ElseIf RemoteFileurl<>"$False$" and SaveTf=False Then'不保存图片 Re.Pattern =TempArray(Tempi) ConStr=Re.Replace(ConStr,RemoteFileUrl) UploadFiles=UploadFiles & "|" & RemoteFileUrl End If Next Set Re=nothing If UploadFiles<>"" Then UploadFiles=Right(UploadFiles,Len(UploadFiles)-1) End If ReplaceSaveRemoteFile=ConStr End function
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
以上就是ASP替换、保存远程图片函数代码,希望对大家的学习有所帮助。
