Upload函数FilePath错误

Question

嘿，伙计们，这里的asp脚本有点问题。以下是我用于用户上传图像的上传功能的代码

<%
' Create the FileUploader
Dim Uploader, File, FileSys, FilePath
Set Uploader = New FileUploader

' This starts the upload process
Uploader.Upload()

' Check if any files were uploaded

If Uploader.Files.Count = 0 Then
    Response.Write "File(s) not uploaded."
Else
    ' Loop through the uploaded files
    For Each File In Uploader.Files.Items

        ' Set upload Path and Filename to check if that file already exists
        FilePath = "C:\inetpub\wwwroot\coursework2\database\uploads\"&File.FileName
        Set FileSys = CreateObject("Scripting.FileSystemObject")

        ' If intended uploaded file already exists in the specified directory do alert and redirect previous page
        If FileSys.FileExists(FilePath) then 
            Response.Write("<script>alert('Sorry FileName:"& File.FileName &" Already Used!!  Please Rename Your Local File')</script>")
            Response.Write("<script>window.location.href='index.asp'</script>")  
        else
            ' Else Save the file
            File.SaveToDisk "C:\inetpub\wwwroot\coursework2\database\uploads"
        end if
    Next
    ' Confirm file saved and redirect to previous page if more files to be uploaded
    Response.Write("<script>alert('File Saved')</script>")  
    Response.Write("<script>window.location.href='index.asp'</script>")  
End If

%>

这是到服务器的连接字符串我也在尝试上载该文件

"Provider=Microsoft.ACE.OLEDB.12.0;Data Source="& Server.MapPath("/dek0272/coursework2/database/uploads")

这就是我想要将文件路径和磁盘位置的File.save设置为

http://focserver.londonmet.ac.uk/dek0272/coursework2/database/uploads/

当我将文件路径和磁盘位置的file.save更改为此地址时。该函数不会上传任何内容。我相信我写错了路。我已经尝试了很多方法来写它，但还是没有成功。

有什么建议吗

谢谢

这是upLoadFunctions.asp文件

您是否收到任何ASP错误消息？如果是，错误代码是什么？如果不是，请尝试一个无效的文件路径，以引起错误(查看文件路径是否有问题)。

Afaik此行

 Set FileSys = CreateObject("Scripting.FileSystemObject")

应该是

Set FileSys = Server.CreateObject("Scripting.FileSystemObject")

另一个可能的错误来源:您是否检查了filepath文件夹是否具有适当的写入权限？有关如何在IIS 7.5 (=Win Server 2008R2)上设置写入权限的信息，请参阅：
