使用PowerShell從virtualbox下載/上傳ftp文件

Question

您好我正在嘗試將文件上傳到運行Linux和ftp服務器的虛擬機。 我在代碼中有一個例外：

    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

我使用的腳本是這樣的：

    # 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是5.1。 我在主機上有代理。

編輯：我現在正在使用下載命令：

# 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)

但是我有這個錯誤：

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

第二次編輯：

# 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()
}

在此之后我得到這個錯誤：

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
+     $session.Open($sessionOptions)
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : SessionRemoteException

我在這里看不到任何代理連接。

Answer 1

FtpWebRequest不支持某些操作的HTTP代理，包括文件上載。 它在MSDN上清楚地記錄在案 ：

如果指定的代理是HTTP代理，則僅支持DownloadFile，ListDirectory和ListDirectoryDe​​tails命令。

使用PowerShell和標准.NET框架庫，無法通過HTTP代理將文件上載到FTP。

您必須使用第三方FTP庫或PowerShell模塊。

例如，使用WinSCP .NET程序集 ，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()
}

有關SessionOptions.AddRawSettings的選項，請參閱原始設置 。

您可以讓WinSCP GUI為您生成PowerShell FTP上傳代碼模板 ，如上所述。

雖然您的實際問題是您在計算機上的Internet連接選項中配置了代理，但實際上您並不想使用它們。

正確的解決方案是修復選項。
轉到“ 控制面板”>“網絡和Internet”>“Internet選項”>“連接”>“LAN”設置 。

或者作為解決方法，在PowerShell代碼中禁用特定連接的代理：

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

請參閱powershell http獲取不使用代理 。
