Question

我正在开发一个FTP自动化脚本，它将某些文件从网络共享上传到FTP服务器上的特定位置。我找到了下面的内容，但无法编辑它以导航到所需的目标目录。

#ftp server 
$ftp = "ftp://SERVER/OtherUser/" 
$user = "MyUser" 
$pass = "MyPass"  

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

#list every sql server trace file 
foreach($item in (dir $Dir "*.trc")){ 
    "Uploading $item..." 
    $uri = New-Object System.Uri($ftp+$item.Name) 
    $webclient.UploadFile($uri, $item.FullName) 
 }

我有FTP服务器的凭据，但默认为/home/MyUser/，我需要直接转到/home/OtherUser/。我有权浏览并上传到该目录，但我无法弄清楚如何基本上cd到该位置。

以下是收到的当前错误：

Exception calling "UploadFile" with "2" argument(s): "The remote server returned an erro
r: (550) File unavailable (e.g., file not found, no access)."
At line:26 char:26
+     $webclient.UploadFile <<<< ($uri, $item.FullName) 
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException

您需要使用FtpWebRequest类型。 WebClient用于HTTP流量。

我编写并测试了一个参数化函数，该函数将文件上传到名为Send-FtpFile的FTP服务器。我使用sample C# code from MSDN将其转换为PowerShell代码，并且效果很好。

function Send-FtpFile {
    [CmdletBinding()]
    param (
          [ValidateScript({ Test-Path -Path $_; })]
          [string] $Path
        , [string] $Destination
        , [string] $Username
        , [string] $Password
    )
    $Credential = New-Object -TypeName System.Net.NetworkCredential -ArgumentList $Username,$Password;

    # Create the FTP request and upload the file
    $FtpRequest = [System.Net.FtpWebRequest][System.Net.WebRequest]::Create($Destination);
    $FtpRequest.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile;
    $FtpRequest.Credentials = $Credential;

    # Get the request stream, and write the file bytes to the stream
    $RequestStream = $FtpRequest.GetRequestStream();
    Get-Content -Path $Path -Encoding Byte | % { $RequestStream.WriteByte($_); };
    $RequestStream.Close();

    # Get the FTP response
    [System.Net.FtpWebResponse]$FtpRequest.GetResponse();
}

Send-FtpFile -Path 'C:\Users\Trevor\Downloads\asdf.jpg' `
    -Destination 'ftp://google.com/folder/asdf.jpg' `
    -Username MyUsername -Password MyPassword;
