在ASP中上传文件 [英] File uploading in ASP

问题描述

我们有一个asp和javascript代码片段，我们正在使用它们通过在线应用程序上传文件.
当前，我们面临的问题是该应用程序允许我们从E/F驱动器上载文件，但不允许我们从C驱动器上载.
应用程序引发警告消息，因为文件不存在或访问被拒绝...

ASP代码片段

we have a asp and javascript code snipet which we are using to upload files via online application.
currently we are facing an issue like the application is allowing us to upload a file from E/F drive but not allowing us to upload from C drive.
application throwing an alert message as File not exist or access denied...

ASP CODE SNIPET

case "FileExist"
	sFileName	= Request.QueryString("FileName")
		Set objFSO = Server.CreateObject("Scripting.FileSystemObject")

		If objFSO.FileExists(sFileName) = true then
			sResult = "Success"
		Else
			sResult = "Not Success"
		End If
		Set objFSO = Nothing
Java script code
		for (var i=1; i<=(document.getElementById('tblFile').rows.length)-1; i++)	
		{			
			if (IsEmpty('cmdBrowse' + i, 'SELECT', 'File', 'Y') == false)
    	return false;

			sFileName = escape(document.getElementById('cmdBrowse' + i).value).replace(gSpecialChar,'%2b');
     	var sURL = "../ADO_Common.asp?PurposeName=FileExist&FileName=" + sFileName;
   //    alert(sURL);	  
			oXMLHTTP.open( "POST", sURL, false );
			oXMLHTTP.send();	     
			if (oXMLHTTP.responseText != "Success")
			{
				alert("File Does Not Exists Or Permission Denied...")
				return false;								
			}		
		}

推荐答案

使用IIS时，授予IUSR_machinename的权限对于这种情况很重要.
如果您没有对IUSR_machinename的C驱动器的写入权限，则上述脚本中将发生错误.

此处讨论/解释的内容相同:使用FileSystemObject写入文本文件 [ ^ ]

如果请求被模拟，那么您需要确保模拟的用户具有安全权限.

When you are using IIS, the permissions granted to IUSR_machinename is important for such scenarios.
If you do not have write permission to the C drive for IUSR_machinename, an error will occur in the above script.

Same thing discussed/explained here: Using the FileSystemObject to Write to Text Files [^]

In case, the requests are impersonated, then you need to make sure that the user impersonated has the security permissions.
