Question

我有以下代码通过powershell将文件上传到FTP服务器，但这给了我这个错误：

代码：

$Directory=”C:\test”

#FTP server configuration
$ftpserver = “ftp://ftpserver/”
$username = “user”
$password = “pw”

$webclient = New-Object System.Net.WebClient

$webclient.Credentials = New-Object System.Net.NetworkCredential($username,$password)

#Copy each file which type is *.tx*
foreach($file in (dir $Directory “*.txt*”)){
“Uploading $file…”
$uri = New-Object System.Uri($ftpserver+$file.Name)
$webclient.UploadFile($uri, $file.FullName)
}

错误：

Exception calling "UploadFile" with "2" argument(s): "Excepção durante um pedido WebClient."
At C:\Users\home\Desktop\test6.ps1:16 char:1
+ $webclient.UploadFile($uri, $file.FullName)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException

尝试一下：

$Directory = "C:\test"

#FTP server configuration
$ftpserver = "ftp://ftpserver/"
$username = "user"
$password = "pw"
$ftpserverURI = New-Object -TypeName System.Uri -ArgumentList $ftpserver, [System.UriKind]::Absolute

$webclient = New-Object System.Net.WebClient
$webclient.Credentials = New-Object -TypeName System.Net.NetworkCredential -ArgumentList $username, $password

#Copy each file which type is *.tx*
Get-ChildItem $Directory -Filter *.txt* | ForEach-Object {
    Write-Host "Uploading $($_.FullName)..."
    $uri = New-Object -TypeName System.Uri -ArgumentList $ftpserverURI, $_.Name
    $webclient.UploadFile($uri, [System.Net.WebRequestMethods+Ftp]::UploadFile, $_.FullName)
}

区别在于，我正在使System.Uri结合路径而不是依赖于字符串连接，并且我告诉WebClient.UploadFile（）上载文件时要使用的方法。

如果这不起作用，那么我同意您应该检查服务器日志的评论。如果不能，请在可以查看其日志的服务器上尝试。或者，您可能想尝试使用WinSCP，它也可以通过PowerShell或自定义脚本文件编写脚本。 WinSCP还具有支持FTP，FTPS和SFTP的优势。据我所知，.Net WebClient仅本地支持纯FTP。

就智能引号而言，它们在Windows PowerShell（<= v5.x）上可以正常工作，但在PowerShell Core（v6 +）上却根本不起作用。我会避免使用它们来使您的代码更具可移植性，并为将来提供更多证明。
