How to upload using FTP in Powershell, behind a proxy?
ftp, powershell, proxy
Solution
Are you sure your proxy supports FTP, or is it HTTP only? See this thread:
FTP File Upload with HTTP Proxy
For WebClient I've used this in the past although it was for HTTP use, but you could give it a try:
$wc = New-Object System.Net.WebClient
$wc.Headers.Add("User-Agent","Mozilla/4.0+")
$wc.Proxy = [System.Net.WebRequest]::DefaultWebProxy
$wc.Proxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
$wc.UploadFile($uri, "C:\Test\1234567.txt")
Note that - "The UploadFile method sends a local file to a resource. This method uses the STOR command to upload an FTP resource. For an HTTP resource, the POST method is used."
Problem
I am attempting to use FTP in Powershell to upload a file. I am using `FtpWebRequest` later followed by `GetRequestStream`, but this method is returning an error: "The requested FTP command is not supported when using HTTP proxy." I am indeed behind a proxy and required to be. How can I upload via Powershell when behind a proxy? This would be solely run from a `.ps1` Powershell script. I have also tried: ``` $webclient = New-Object System.Net.WebClient $uri = New-Object System.Uri($server) $webclient.UploadFile($uri, "C:\Test\1234567.txt") ``` Where `$server` and that file are valid. But that code returns this error: ``` "An exception occurred during a WebClient request." At C:\Test\script.ps1:101 char:26 + $webclient.UploadFile <<<< ($uri, "C:\Test\1234567.txt") + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException ``` I also tried double backslashes in the file paths, didn't help. The proxy I am under only touches HTTP, and not FTP.
