尝试使用PowerShell将文件上传到FTP

Question

我正在尝试使用PowerShell将文件上传到FTP，这会给我以下错误：

  

使用2个参数“无法连接到远程服务器”的异常调用“ uploadfile”。

$dir = “dir”
$ftp = “ftp”

$user = ...
$password = ...

$webclient = New-Object System.Net.WebClient
$webclient.Credentials = New-Object System.Net.NetworkCredentials($user, $password)
foreach ($item in (dir $dir “*”)) {
    $uri = New-Object System.Uri($ftp + $item.Name)
    $webclient.UploadFile($uri, $item.FullName)
}
