將文件通過 FTP 傳輸到遠程 Windows 服務器的 Powershell 腳本

Question

我一直在努力讓一個腳本可以工作，該腳本可以將文件通過 FTP 傳輸到遠程 Windows 服務器，我想看看我是否能得到一些幫助。 我在 StackOverflow 和 Google 上搜索了多個頁面，但到目前為止都沒有成功。下面是我的代碼

邏輯如下：

1. 拿起文件夾中帶有模式的最舊文件
2. 連接到 FTP 服務器
3. 將文件復制到遠程服務器
4. 將文件從 in 文件夾移動到存檔文件夾

我嘗試將文件通過 FTP 傳輸到服務器的代碼似乎失敗了 - $webclient.UploadFile($uri,$latestfile)

得到這個異常：

使用“2”個參數調用“UploadFile”的異常：“WebClient 請求期間發生異常。” 在 C:\\Downloads\\powershell\\testmove3.ps1:22 char:26 + $webclient.UploadFile <<<< ($uri,$latestfile) + CategoryInfo : NotSpecified: (:) [], MethodInvocationException +fullyQualifiedErrorId : DotNetMethodException

$source = "C:\downloads\"
$destination = "C:\dest\"
Get-ChildItem -Path C:\downloads | Where-Object { $_.name -like "TEST.CSV-PlainText*.txt" }

$latestfile=gci -path $source | Where-Object { $_.name -like "TEST.CSV-PlainText*.txt"} | sort FirstWriteTime | select -last 1

"Oldest File $latestfile"


## Get ftp object
$ftp_client = New-Object System.Net.WebClient
$user="someuser"
$pass="somepass"
$ftp_address = "ftp://ftp.testserver.com"


## Make uploads
$uri = New-Object System.Uri($ftp+$item.Name)
"Item is $latestfile"
$webclient.UploadFile($uri,$latestfile)
"File uploaded to remote servr"

Move-Item $latestfile.FullName $destination
"File $latestfile moved"

好的，一夜之間，很高興地報告我得到了一個解決方案 - yeeehaw ！

我什至添加了一個邏輯來捕獲異常並發送電子郵件通知。 希望這可以幫助任何使用 Powershell 解決 FTP 問題的人。 最后，它向調用程序返回成功或失敗代碼。

#PowerShell.exe -File "C:\temp\FTP.ps1"

trap [Exception] { 
    $recipient = "recipient@yahoo.com"
        $sender = "sender@yahoo.com"
        $server = "test.mailserver.com"
        $subject =  "FTP Test"
        $body = "Exception Title: " + $_.Exception.GetType().FullName + "`r`n`r`n" + "Exception Details: " + $_.Exception.Message
        $msg = new-object System.Net.Mail.MailMessage $sender, $recipient, $subject, $body
        $client = new-object System.Net.Mail.SmtpClient $server
        $client.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
        $client.Send($msg)

        exit 1 
        }



    $ftpuser  = "testuser"
    $ftppass =  "testpass"  
    $ftpserver =  "ftp://ftp.testserver.com/" 
    $file =  "C:\temp\one.txt"
    $filenewname = "one.txt"
    $webclient =  New-Object System.Net.WebClient
    $ftp =  $ftpserver+$filenewname
    $uri =  New-Object System.Uri($ftp)

    #Error was happening because the method call was attempting to use the HttpProxy on the Server machine. 
    #If the proxy is not set to null explicitly in your code, then you will get error - "An exception occurred during a webclient request"
    $webclient.Proxy = $NULL 

    $webclient.Credentials = New-Object System.Net.NetworkCredential($ftpuser,$ftppass)  
    "Uploading $filenewname in $ftpserver"
    $webclient.UploadFile($uri,$file)
    "Uploaded $filenewname in $ftpserver"


return 0

如果要在任何實時支持環境中使用它，我建議使用密碼提示：

$ftppass = Read-Host "Enter password" -AsSecureString
