缺点：安全性不是太差了，还行，只要你充分利用系统自带的工具；唯一缺点就是执行效率慢，如何进行网站优化以后，效果会比较好。无组件Example.asp
<%@LANGUAGE="VBSCRIPT"CODEPAGE="65001"%>
<!--#includefile="SundyUpload.asp"-->
<%
此例子文档编码都是UTF-8,假如是其他编码的体系，请将编码转换为响应的编码，否则表单猎取数据大概会乱码
DimobjUpload,opt
DimxmlPath
DimfileFormName,objFile,counter
opt=request.QueryString("opt")
Ifopt="Upload"Then
xmlPath=Server.MapPath(request.QueryString("xmlPath"))将假造路径转换为实践路径
SetobjUpload=newSundyUpload创建上传工具
objUpload.UploadInitxmlPath,"utf-8"
counter=1
Response.Write("一般表单："&objUpload.Form("normalForm")&"<BR><BR>")猎取表双数据
ForEachfileFormNameInobjUpload.objFile
SetobjFile=objUpload.objFile(fileFormName)
fileSize=objFile.FileSize
strTemp=objFile.FilePath
Response.WritestrTemp
fileName=mid(strTemp,InStrRev(strTemp,"")+1)
IffileSize>0Then
Response.Write("FileSize:"&fileSize&"<BR>")
Response.Write("FileName:"&objFile.FilePath&"<BR>")
Response.Write("FileDescription:"&objUpload.Form("fileDesc"&counter)&"<BR><BR>")
objFile.SaveAsServer.MapPath(".")&"upload"&fileName
Response.Write"Saveat:"&Server.MapPath(".")&"upload"&fileName&"<br><br>"
EndIf

为上载进度条数据文件（XML文件指定假造路径）
最好是随机的，由于大概多团体同时上载，必要分歧的进度数据
这个路径必要在提交的时分传进上载组件中，以便在上载过程当中变动进度数据
客户端利用javascript来读取此XML文件，显现进度

在实现ERP等高端的ASP应用时，用户需要提供核心的经营资料，需要ASP商有很高的信用度。楼上说交互性不好，太牵强了吧。在微软提供的一套框架中，利用asp做网站，开发效率高，使用人数少，减少不必要的开销。交互性是互动方式，是有开发人员决定的。 |
