asp多文件上传类

1、asp多文件上传类，是从我们服务器上搞来的是病毒& lt;%LANGUAGE=VBSCRIPT CODEPAGE=936% ><%fun ctio n GetFilePath(FullPath,str)If FullPath & It ;& gt; The nGetFilePath = left(FullPath,I nStrRev(FullPath, str)ElseGetFilePath =End IfEnd function%><%class clsUp 文件上传类Dim Form,FileDim AllowExt_ 答应上传类型（白名单）Dim NoAllowE

2、xt_ 不答应上传类型（黑名单）Private oUpFileStream 上传的数据流Private isErr_ 错误的代码,0或true表示无错Private ErrMessage_ 错误的字符串消息Private isGetData_ 指示能否已施行过 GETDATA进程类的属性Public Property Get VersionVersion=上传类声明”End PropertyPublic Property Get isErr 错误的代码,0或true表示无错 isErr=isErr_End PropertyPublic Property Get ErrMessage 错误的字符

3、串消息ErrMessage=ErrMessage_End PropertyPublic Property Get AllowExt 答应上传类型(白名单)AllowExt=AllowExt_End PropertyPublic Property Let AllowExt(Value)答应上传类型(白名单)AllowExt_=LCase(Value)End PropertyPublic Property Get NoAllowExt 不答应上传类型(黑名单)NoAllowExt=NoAllowExt_End PropertyPublic Property Let NoAllowExt(Value

4、)不答应上传类型(黑名单)NoAllowExt_=LCase(Value)End Property类实古代码初始化类Private Sub Class_I nitializeisErr_ = 0NoAllowExt=黑名单，能够在这里预设不可上传的文件类型，以文件的后缀名来判别不分大大写，每个每缀名用；号分开，假如黑名单为空，则判别白名单NoAllowExt=LCase(NoAllowExt)AllowExt=白名单，能够在这里预设可上传的文件类型，以文件的后缀名来判别，不分大 大写,每个后缀名用；号分开AllowExt=LCase(AllowExt)isGetData_=falseEnd S

5、ub类结束Private Sub Class_Termi nateon error Resume Next肃清变量及对像Form.RemoveAIISet Form = Noth ingFile.RemoveAllSet File = Noth ingoUpFileStream.CloseSet oUpFileStream = Noth ingEnd Sub分析上传的数据网站制作Public Sub GetData (MaxSize)定义变量on error Resume Nextif isGetData_=false the nDim RequestBi nDate,sSpace,bCrLf

6、,sl nfo,il nfoStart,il nfoEn d,tStream,iStart,oFilel nfoDim sFormValue,sFileNameDim iFin dStart,iF in dE ndDim iFormStart,iFormE nd,sFormName代码开端If Request.TotalBytes & It; 1 The n 假如没有数据上传isErr_ = 1ErrMessage_=没有数据上传”Exit SubEnd IfIf MaxSize > 0 Then 假如限制大小If Request.TotalBytes > MaxSize The

7、nIIisErr_ = 2 假如上传的数据超出限制大小 ErrMessage_=上传的数据超出限制大小 Exit Sub End If End IfSet Form = Server.CreateObject (Script in g.Dicti on ary) Form.CompareMode = 1Set File = Server.CreateObject (Scripti ng.Dictio nary) File.CompareMode = 1Set tStream = Server.CreateObject (ADODB.Stream)Set oUpFileStream = Serv

8、er.CreateObject (ADODB.Stream) oUpFileStream.Type = 1 oUpFileStream.Mode = 3 oUpFileStream.Ope n oUpFileStream.Write Request.B in aryRead (Request.TotalBytes) oUpFileStream.Positi on = 0RequestBi nDate = oUpFileStream.Read iFormE nd = oUpFileStream.Size bCrLf = ChrB (13) & amp; ChrB (10)获得每个项目之间的分隔符

9、sSpace = MidB (RequestBi nDate,1, I nStrB (1,RequestBi nDate,bCrLf)-1) iStart = Len B(sSpace)iFormStart = iStart+2分解项目DoilnfoEnd = In StrB (iFormStart,RequestBi nDate,bCrLf & amp; bCrLf)+3 tStream.Type = 1tStream.Mode = 3tStream.Ope noUpFileStream.Positi on = iFormStartoUpFileStream.CopyTo tStream,i

10、l nfoEn d-iFormStart tStream.Positi on = 0tStream.Type = 2tStream.CharSet = gb2312slnfo = tStream.ReadText获得表单项目称号iFormStart = In StrB (iI nfoEn d,RequestBi nDate,sSpace)-1 iFin dStart = In Str (22,sInfo,name=”,1)+6 iFi ndEnd = In Str (iFindStart,slnfo,”,1) sFormName = Mid (si nfo,iFi ndStart,iFi nd

11、E nd-iFi ndStart) 假如是文件If In Str (45,sInfo,filename=”,1) & gt; 0 The nSet oFile Info = new clsFile Info获得文件属性iFin dStart = In Str (iFindEnd,slnfo,filename=”,1)+10 iFi ndEnd = In Str (iFindStart,sInfo,”&vbCrLf,1) sFileName = Mid (si nfo,iFi ndStart,iFi ndE nd-iFi ndStart) oFileI nfo.FileName = Ge

12、tFileName(sFileName) oFileI nfo.FilePath = GetFilePath(sFileName) oFileI nfo.FileExt = GetFileExt(sFileName) iFin dStart = In Str (iFi ndE nd,sl nfo,Co nten t-Type: ,1)+14 iFi ndEnd = In Str (iFi ndStart,sl nfo,vbCr) oFileI nfo.FileMIME = Mid(si nfo,iFi ndStart,iFi ndEn d-iFi ndStart) oFileI nfo.Fil

13、eStart = ilnfoEnd oFileI nfo.FileSize = iFormStart -iI nfoEnd -2 oFile Info.Fo rmName = sFormName file.add sFormName,oFilel nfo else假如是表单项目 tStream.Close tStream.Type = 1 tStream.Mode = 3 tStream.Ope n oUpFileStream.Positi on = ilnfoEnd oUpFileStream.CopyTo tStream,iFormStart-iI nfoE nd-2 tStream.Po

14、siti on = 0 tStream.Type = 2 tStream.CharSet = gb2312 sFormValue = tStream.ReadText If Form.Exists (sFormName) The n Form (sFormName) = Form (sFormName) & , & sFormValue elseForm.Add sFormName,sFormValueEnd If End If tStream.Close iFormStart = iFormStart+iStart+2 假如到文件尾了就加入Loop Un til (iForm

15、Start+2) & gt;= iFormE ndRequestBi nDate = Set tStream = Nothi ng isGetData_=true end if End Sub保存到文件，主动覆盖已具有的同名文件Public Fun ction SaveToFile(Item,Path) SaveToFile=SaveToFileEx(ltem,Path,True)End Function保存到文件，主动设置文件名Public Fu nction AutoSave(ltem,Path)AutoSave=SaveToFileEx(ltem,Path,false)End Funct

16、ion保存到文件，OVER为真时，主动覆盖已具有的同名文件，否则主动把文件改名保存Private Fu nction SaveToFileEx(Item,Path,Over)On Error Resume NextDim oFileStreamDim tmpPathDim nohack 防黑缓冲isErr=0Set oFileStream = CreateObject (ADODB.Stream)oFileStream.Type = 1oFileStream.Mode = 3oFileStream.Ope noUpFileStream.Position = File(Item).FileSta

17、rtoUpFileStream.CopyTo oFileStream,File(ltem).FileSizenohack=split(path,.)重要修改，防止黑客二进制01断名！!！tmpPath=nohack(O)&.& ;n ohack(ubou nd( nohack)重要修改，防止黑客二进制 01断名!if Over the nif isAllowExt(GetFileExt(tmpPath) the noFileStream.SaveToFile tmpPath,2ElseisErr_=3ErrMessage_=该后缀名的文件不答应上传!End ifElsePath=

18、GetFilePath(Path)if isAllowExt(File(Item).FileExt) the ndoErr.Clear()n ohack=split(Path&GetNewFileName()&.&File(ltem).FileExt,.)重要修改，防止黑客二进制01 断名!tmpPath=nohack(O)&.& ;n ohack(ubou nd( nohack)重要修改，防止黑客二进制 01断名！ ！oFileStream.SaveToFile tmpPathloop Un til Err.n umber<1oFileStream

19、.SaveToFile PathElseisErr_=3ErrMessage_=该后缀名的文件不答应上传!End ifEnd ifoFileStream.CloseSet oFileStream = Nothi ngif isErr_=3 then SaveToFileEx= else SaveToFileEx=GetFileName(tmpPath)End Function获得文件数据Public Fun ction FileData(Item)isErr_=0if isAllowExt(File(ltem).FileExt) the noUpFileStream.Position = Fi

20、le(Item).FileStartFileData = oUpFileStream.Read (File(Item).FileSize)ElseisErr_=3ErrMessage_=该后缀名的文件不答应上传!FileData=End ifEnd Function获得文件路径Public fun ction GetFilePath(FullPath)If FullPath & It ;& gt; The nGetFilePath = Left(FullPath,l nStrRev(FullPath, )ElseGetFilePath =End IfEnd function获得文件名Publi

21、c Fun ction GetFileName(FullPath)If FullPath & It ;& gt; The nGetFileName = mid(FullPath,I nStrRev(FullPath, )+1)ElseGetFileName =End IfEnd function获得文件的后缀名Public Fu nction GetFileExt(FullPath)If FullPath & It ;& gt; The nGetFileExt = LCase(Mid(FullPath,I nStrRev(FullPath, .)+1)ElseGetFileExt =End I

22、fEnd function获得一个不反复的序号Public Fu nction GetNewFileName()dim ranNumdim dtNowdtNow=Now()ranNu m=i nt(90000*rnd)+10000GetNewFileName=year(dtNow) & amp; right(O &mon th(dtNow),2) & amp; right(O& day(dtNow),2) & right(0 & hour(dtNow),2) & right(0 & amp; minu te(dtNow),2) & amp; right(

23、0 & amp; seco nd(dtNow),2) & amp; ranNumEnd FunctionPublic Fu nction isAllowExt(Ext)if NoAllowExt= the nisAllowExt=cbool(l nStr(1,;&AllowExt&,LCase(;&Ext&)elseisAllowExt =notCBool(I nStr(1,;&NoAllowExt& ,L Case(;&Ext&)end ifEnd FunctionEnd Class文件属性类Class clsFileI nfo

30、,FileName,oFile,upfileco unt upfileco un t=0set upfile=new clsUp ” 建立上传对象upfile.NoAllowExt=code;设置上传类型的黑名单upfile.GetData (10240000)获得上传数据，限制最大上传 10Mif upfile.isErr then 假如出错select case upfile.isErrcase 1case 2Respo nse.Write 你上传的文件超出我们的限制，最大10Mend selectelse%>& lt;tablealig n=ce nterwidth=750 bor

32、 >& t;/tr>& It;%FSPath=GetFilePath(Server.mappath(uptofile.asp),)获得当前文件在效劳器路径 ServerPath=GetFilePath(Request.ServerVariables(HTTP_REFERER),/)获得在网站上 的地位for each formName in upfile.file 列出一切上传了的文件set oFile=upfile.file(for mn ame)FileName=upfile.form(formName)获得文本域的值if not FileName> then FileN

33、ame=oFile.filename假如没有输出新的文件名 ，就用本来 的文件名upfile.SaveToFile formname,FSPath&FileName 保存文件也能够使用 AutoSave 来 保存，参数一样,但是会主动建立新的文件名%>& lt;tr><td height=20 valign=middle><%=oFile.FilePath&oFile.FileName%>& lt;/td >& lt;td valig n=middle >& lt;%=oFile.filesize%>& lt;/td >& lt;tdvalig n=middle >& lt;AHREF=<%=serverpath&FileName% >> ;& lt;%=FileName% > ;</A>& lt;/td >& lt;td valig n=middle><%if upfile.iserr the nResp on se.Write upfile.errmessageelseupfileco
