我试图将文件上传到运行Linux和FTP服务器的虚拟机上。我在代码中有一个例外：

Exception calling "GetRequestStream" with "0" argument(s): "The requested FTP command is not supported when using HTTP proxy."
At D:\Users\h.yordanov\Desktop\PowerShellFtp-master\script.ps1:21 char:1
+ $Run = $FTPRequest.GetRequestStream()
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : InvalidOperationException

我用的脚本是：

# Config
$Username = "sammy"
$Password = "1111"
$LocalFile = "C:\fff\medias\1618716-maybach-exelero.jpg"
$RemoteFile = "ftp://192.168.56.101/files/1618716-maybach-exelero.jpg"

# Create FTP Rquest Object

$FTPRequest = [System.Net.FtpWebRequest]::Create("$RemoteFile")
$FTPRequest = [System.Net.FtpWebRequest]$FTPRequest
$FTPRequest.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile
    
$FTPRequest.Credentials = new-object System.Net.NetworkCredential($Username, $Password)
$FTPRequest.UseBinary = $true
$FTPRequest.UsePassive = $true
# Read the File for Upload
$FileContent = gc -en byte $LocalFile
$FTPRequest.ContentLength = $FileContent.Length
# Get Stream Request by bytes
$Run = $FTPRequest.GetRequestStream()
$Run.Write($FileContent, 0, $FileContent.Length)
# Cleanup
$Run.Close()

$Run.Dispose()

PowerShell ver为5.1。我在主机上有代理。

当尝试下载时：

# Config
$Username = "sammy"
$Password = "1111"
$LocalFile = "C:\fff\medias\1618716-maybach-exelero.jpg"
$RemoteFile = "ftp://192.168.56.101/files/1618716-maybach-exelero.jpg"

# Create a FTPWebRequest 
$FTPRequest = [System.Net.FtpWebRequest]::Create($RemoteFile) 
$FTPRequest.Credentials = New-Object System.Net.NetworkCredential($Username,$Password) 
$FTPRequest.Method = [System.Net.WebRequestMethods+Ftp]::DownloadFile 
$FTPRequest.UseBinary = $true 
$FTPRequest.KeepAlive = $false
# Send the ftp request
$FTPResponse = $FTPRequest.GetResponse() 
# Get a download stream from the server response 
$ResponseStream = $FTPResponse.GetResponseStream() 
# Create the target file on the local system and the download buffer 
$LocalFileFile = New-Object IO.FileStream ($LocalFile,[IO.FileMode]::Create) 
[byte[]]$ReadBuffer = New-Object byte[] 1024 
# Loop through the download 
do { 
    $ReadLength = $ResponseStream.Read($ReadBuffer,0,1024) 
    $LocalFileFile.Write($ReadBuffer,0,$ReadLength) 
} 
while ($ReadLength -ne 0)

我有一个错误：

Exception calling "GetResponse" with "0" argument(s): "The remote server returned an error: (403) Forbidden."
At D:\Users\h.yordanov\Desktop\PowerShellFtp-master\script.ps1:16 char:1
+ $FTPResponse = $FTPRequest.GetResponse()
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : WebException

尝试WinSCP .NET程序集时：

# Load WinSCP .NET assembly
Add-Type -Path "D:\Users\h.yordanov\Desktop\PowerShellFtp-master\WinSCPnet.dll"

# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Ftp
    HostName = "192.168.56.101"
    UserName = "sammy"
    Password = "1111"
}

# Configure proxy
$sessionOptions.AddRawSettings("ProxyMethod", "1")
$sessionOptions.AddRawSettings("ProxyHost", "proxy.abc.dfg.bg")

$session = New-Object WinSCP.Session

try
{
    # Connect
    $session.Open($sessionOptions)

    # Upload file
    $LocalFile = "C:\fff\medias\test2.txt"
    $RemoteFile = "/home/sammy/ftp/files/test2.txt"
    $session.PutFiles($LocalFile, $RemoteFile).Check()
}
finally
{
    $session.Dispose()
}

我知道这个错误：

Exception calling "Open" with "1" argument(s): "Connection failed.
Can't connect to proxy server
No connection could be made because the target machine actively refused it.
Connection failed."
At D:\Users\h.yordanov\Desktop\PowerShellFtp-master\script.ps1:21 char:5

    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : SessionRemoteException

通过FileZilla从连接中登录。(我改变了ip)

FtpWebRequest不支持某些操作(包括文件上传)的HTTP。很明显是记录在MSDN上

如果指定的代理是HTTP代理，则只支持DownloadFile、ListDirectory和ListDirectoryDetails命令。

无法使用PowerShell和标准.NET框架库通过HTTP将文件上载到FTP。

您必须使用第三方FTP库或PowerShell模块。

例如，对于WinSCP .NET组装，您可以使用：

# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"

# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Ftp
    HostName = "ftp.example.com"
    UserName = "user"
    Password = "mypassword"
}

# Configure proxy
$sessionOptions.AddRawSettings("ProxyMethod", "3")
$sessionOptions.AddRawSettings("ProxyHost", "proxy")

$session = New-Object WinSCP.Session

try
{
    # Connect
    $session.Open($sessionOptions)

    # Upload file
    $LocalFile = "C:\fff\medias\1618716-maybach-exelero.jpg"
    $RemoteFile = "/files/1618716-maybach-exelero.jpg"
    $session.PutFiles($LocalFile, $RemoteFile).Check()
}
finally
{
    $session.Dispose()
}

有关SessionOptions.AddRawSettings的选项，请参见原始设置。

你可以拥有WinSCP图形用户界面生成PowerShell FTP上传代码模板，就像上面一样，给你。

(我是WinSCP的作者)

尽管您的实际问题是您在计算机上的Internet连接选项中配置了代理，但实际上您不想使用它们。

正确的解决方案是修复这些选项。

转到控制面板>网络和Internet > Internet选项>连接> LAN设置。

或者作为解决办法，在PowerShell代码中禁用特定连接的代理：

$FTPRequest.Proxy = [System.Net.GlobalProxySelection]::GetEmptyWebProxy()

见绕过PowerShell HTTP中的系统代理设置。
