关于如何使用IIS创建asp服务，请读者自行研究
根目录
filecloudEV.html 提前验证
filecloudEV.aspx 判断密码是否正确
filecloudMAIN.aspx 主界面
UpLoad.asp 上传界面
SaveFile.asp 保存文件
InputFilename.aspx 让用户输入文件名
AddPath.aspx 将当前文件加入文件清单
clsField.asp 文件上传的底层支持代码
clsUpload.asp 文件上传的底层支持代码
DownLoad.aspx 下载界面
list.txt 用户上传的文件的清单
files 用户上传的文件的储存文件夹
<html> <head> <title>filecloud early verification</title> <meta charset="UTF-8"></meta> </head> <body> <form action="filecloudEV.aspx" method="post"> <center> <p style="font-size:50px;">Password</p> <input type="password" name="password" style="font-size:50px;"></input> <input type="submit" value="Submit" style="font-size:50px;"></input> </center> </form> </body> </html>
一个文本框，将用户输入的密码传到filecloudEV.aspx里面去
<html> <head> <title>filecloud early verification</title> <meta charset="UTF-8"></meta> </head> <body> <% dim a a=Request.Form("password") response.write("<center><p style=""font-size:30px"">") if a="XXXXXXX" then ‘验证密码是否正确 response.write("Password is right!")%> <form action="filecloudMAIN.aspx" method="post"><!--只有正确才显示这个跳转按钮--> <input type="submit" value="跳转" style="font-size:30px"></input> </form> <% else response.write("Password is wrong!") response.write("Please go back") end if response.write("</p></center>") %> </body> </html>
然后进入主界面：
<html> <head> <title>FilecloudMAIN</title> <meta charset="UTF-8"></meta> </head> <body> <center> <a href="./UpLoad.asp" style="font-size:50px">UpLoad</a><br /><br /> <a href="./DownLoad.aspx" style="font-size:50px">DownLoad</a><br /><br /> </center> </body> </html>
其实就只是显示了两个超链接:
先来介绍一下上传：
<html> <head> <title>UpLoad</title> <meta charset="UTF-8"> </head> <body> <form method="post" encType="multipart/form-data" action="SaveFile.asp"> <input type="File" name="File1"> <input type="Submit" value="Upload"> </form> </body> </html>
把文件流传到SaveFile.asp中
<!--#INCLUDE FILE="clsUpload.asp"--> <!--引用clsUpLoad.asp--> <html> <head> <title>SaveFile</title> <meta charset="UTF-8"> </head> <body> <% Dim Upload Dim Folder Set Upload = New clsUpload Folder = Server.MapPath("Uploads") & "\" ‘绑定储存文件的路径 Upload("File1").SaveAs Folder & Upload("File1").FileName ‘保存文件 Set Upload = Nothing Response.Write("<script>alert(‘UpLoad Success!‘);window.location.href=‘InputFilename.aspx‘</script>") ‘跳转到InputFilename.aspx %> </body> </html>
接下来介绍一下clsUpload.asp
声明：这个文件以及下面的clsField.asp都是我从Stack Overflow中找到的

但是我们还需要把这个文件名加到文件列表中（如果说不添加，可以在服务器后端运行一个不断获取文件夹内的文件列表写入list.txt比较麻烦
于是我们就需要让用户自己输入刚才上传的文件名：

上传到此结束，接下来看下载

到此，所有文件都写完了，接下来可以http://localhost:端口/filecloudEV.html查看效果了
