使用Powershell进行FTP上载文件的年月日目录结构

Question

I currently have a PowerShell script for periodically uploading certain files to an FTP server. This script dumps every file into one main folder. What I would like to have is a script that uploads the files in a (root)/year/month/day structure.

I have checked a lot of places for some script I would be able to use for this purpose, but couldn't get any of them to work.

Any suggestions? I must've tried the first 100 results on google.

'Dump it all into one folder' upload script:

$webclient = New-Object System.Net.WebClient  

$webclient.Credentials = New-Object
System.Net.NetworkCredential($user,$pass)   

foreach($item in ($checkitems)){  

    Write-host  "Uploading $item..."  -ForegroundColor Green 
    $dt = Get-Date 
    Add-Content $log3 "$dt : Uploading $item..." 

    $name=$item.Name
    $name=[System.Uri]::EscapeDataString($name)
    $uri = New-Object System.Uri($ftp+$name+"")
    $webclient.UploadFile($uri, $item.FullName) 

    if($error -ne $null) 
    { 
        Write-Host "Items will not be moved" -ForegroundColor Red 
    } 
    else 
    { 
        Write-Host "Moving $item to processed" -ForegroundColor green 
        Move-Item $item.Fullname $processed 
        $dt = Get-Date 
        Add-Content $log3 "$dt : Moving $item to processed" 
    } 
 }  

Some of the sources I already checked, for completeness sake:

This will upload the file to yy/mm/dd folder:

$uri = New-Object System.Uri($ftp + $(Get-Date -f "yyyy/MM/dd") + "/" + $name)

(assuming the $ftp already ends with a slash)

But the folder has to exist already.

If the folder does not exist, you have to create it:
Creating a directory on remote FTP using powershell

You may need to create all the levels:

• $ftp + $(Get-Date -f "yyyy")
• $ftp + $(Get-Date -f "yyyy/MM")
• $ftp + $(Get-Date -f "yyyy/MM/dd")

Obviously storing the Get-Date to a variable and reusing it, is a good idea. To protect your from problems, if a new day started in the middle of the execution.
