上传
一段简单的ASP文件上传源代码示例,精简实用。
以下是upload.asp代码: <form name="FORM" action="upload.asp" method="post"> <input type="submit" name="submit" value="OK"> <input type="file" name="file1" <input type=TEXT name=myface size=20 maxlength=100> </form> <% if Request.Form("file1")<>"" then Dim AllowExt_ ’允许上传类型(白名单) Dim NoAllowExt_ ’不允许上传类型(黑名单) NoAllowExt="exe;gif" ’黑名单,可以在这里预设不可上传的文件类型,以文件的后缀名来判断,不分大小写,每个每缀名用;号分开,如果黑名单为空,则判断白名单 NoAllowExt=LCase(NoAllowExt) AllowExt="" ’白名单,可以在这里预设可上传的文件类型,以文件的后缀名来判断,不分大小写,每个后缀名用;号分开 AllowExt=LCase(AllowExt) Function GetFileName(ByVal strFile) If strFile <> "" Then GetFileName = mid(strFile,InStrRev(strFile, "\")+1) Else GetFileName = "" End If End function Function isAllowExt(Ext) if NoAllowExt="" then isAllowExt=cbool(InStr(1,";"&AllowExt&";",LCase(";"&Ext&";"))) else isAllowExt=not CBool(InStr(1,";"&NoAllowExt&";",LCase(";"&Ext&";"))) end if End Function Public Function GetFileExt(FullPath) If FullPath <> "" Then GetFileExt = LCase(Mid(FullPath,InStrRev(FullPath, ".")+1)) Else GetFileExt = "" End If End function uppath="uploadfile\" strFileName = Request.Form("file1") strnum=trim(Len(strFileName)) filetype= mid(strFileName,strnum-2,3) if isAllowExt(filetype) then Set objStream = Server.CreateObject("ADODB.Stream") objStream.Type = 1 ’ adTypeBinary objStream.Open objStream.LoadFromFile strFileName objStream.SaveToFile Server.MapPath(uppath&GetFileName(strFileName)),2 objStream.Close response.write "<script>parent.document.forms[0].myface.value=’" &uppath&"/"&GetFileName(strFileName)& "’</script>" response.write "<a href=’" &uppath&GetFileName(strFileName)& "’>查看头像</a>" response.write "文件类型:"&filetype&"" else response.write"<SCRIPT language=JavaScript>alert(’头像文件只允许用GIF文件格式!’);" response.write"this.location.href=’javascript:history.back();’</SCRIPT>" response.end end if end if %> |
