我想使用PowerShell将文件与FTP一起传输到匿名FTP服务器。我不会使用任何额外的包。怎么样？
脚本必须没有挂起或崩溃的风险。
答案 0 :(得分：76)
我不确定你是否可以100％防止脚本不挂起或崩溃，因为有些东西无法控制（如果服务器在上传中途失去了什么？） - 但这应该为获取提供坚实的基础你开始了：
# create the FtpWebRequest and configure it
$ftp = [System.Net.FtpWebRequest]::Create("ftp://localhost/me.png")
$ftp = [System.Net.FtpWebRequest]$ftp
$ftp.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile
$ftp.Credentials = new-object System.Net.NetworkCredential("anonymous","anonymous@localhost")
$ftp.UseBinary = $true
$ftp.UsePassive = $true
# read in the file to upload as a byte array
$content = [System.IO.File]::ReadAllBytes("C:\me.png")
$ftp.ContentLength = $content.Length
# get the request stream, and write the bytes into it
$rs = $ftp.GetRequestStream()
$rs.Write($content, 0, $content.Length)
# be sure to clean up after ourselves
$rs.Close()
$rs.Dispose()

还有其他一些方法。我使用了以下脚本：
$File = "D:\Dev\somefilename.zip";
$ftp = "ftp://username:password@example.com/pub/incoming/somefilename.zip";
Write-Host -Object "ftp url: $ftp";
$webclient = New-Object -TypeName System.Net.WebClient;
$uri = New-Object -TypeName System.Uri -ArgumentList $ftp;
Write-Host -Object "Uploading $File...";
$webclient.UploadFile($uri, $File);
您可以使用以下命令对Windows FTP命令行实用程序运行脚本
ftp -s:script.txt
（查看this article）

我不会声称这比最高投票的解决方案更优雅......但这很酷（好吧，至少在我看来是LOL）以自己的方式：
$server = "ftp.lolcats.com"
$filelist = "file1.txt file2.txt"
"open $server
user $user $password
binary
cd $dir
" +
($filelist.split(' ') | %{ "put ""$_""`n" }) | ftp -i -in
正如您所看到的，它使用了那个极简的内置Windows FTP客户端。也更短，更直接。是的，我实际上已经使用了它并且它有效！

我最近为powershell写了几个与FTP通信的函数，请参阅https://github.com/AstralisSomnium/PowerShell-No-Library-Just-Functions/blob/master/FTPModule.ps1。下面的第二个功能，您可以将整个本地文件夹发送到FTP。在该模块中，甚至是递归删除/添加/读取文件夹和文件的功能。
#Add-FtpFile -ftpFilePath "ftp://myHost.com/folder/somewhere/uploaded.txt" -localFile "C:\temp\file.txt" -userName "User" -password "pw"
function Add-FtpFile($ftpFilePath, $localFile, $username, $password) {
$ftprequest = New-FtpRequest -sourceUri $ftpFilePath -method ([System.Net.WebRequestMethods+Ftp]::UploadFile) -username $username -password $password
Write-Host "$($ftpRequest.Method) for '$($ftpRequest.RequestUri)' complete'"
$content = $content = [System.IO.File]::ReadAllBytes($localFile)
$ftprequest.ContentLength = $content.Length
$requestStream = $ftprequest.GetRequestStream()
$requestStream.Write($content, 0, $content.Length)
$requestStream.Close()
$requestStream.Dispose()
}
#Add-FtpFolderWithFiles -sourceFolder "C:\temp\" -destinationFolder "ftp://myHost.com/folder/somewhere/" -userName "User" -password "pw"
function Add-FtpFolderWithFiles($sourceFolder, $destinationFolder, $userName, $password) {
Add-FtpDirectory $destinationFolder $userName $password
$files = Get-ChildItem $sourceFolder -File
foreach($file in $files) {
$uploadUrl ="$destinationFolder/$($file.Name)"
Add-FtpFile -ftpFilePath $uploadUrl -localFile $file.FullName -username $userName -password $password
}
}
#Add-FtpFolderWithFilesRecursive -sourceFolder "C:\temp\" -destinationFolder "ftp://myHost.com/folder/" -userName "User" -password "pw"
function Add-FtpFolderWithFilesRecursive($sourceFolder, $destinationFolder, $userName, $password) {
Add-FtpFolderWithFiles -sourceFolder $sourceFolder -destinationFolder $destinationFolder -userName $userName -password $password
$subDirectories = Get-ChildItem $sourceFolder -Directory
$fromUri = new-object System.Uri($sourceFolder)
foreach($subDirectory in $subDirectories) {
$toUri = new-object System.Uri($subDirectory.FullName)
$relativeUrl = $fromUri.MakeRelativeUri($toUri)
$relativePath = [System.Uri]::UnescapeDataString($relativeUrl.ToString())
$lastFolder = $relativePath.Substring($relativePath.LastIndexOf("/")+1)
Add-FtpFolderWithFilesRecursive -sourceFolder $subDirectory.FullName -destinationFolder "$destinationFolder/$lastFolder" -userName $userName -password $password
}
}

这是我的超酷版本，因为它有一个进步条： - ）
我知道这是一个完全无用的功能，但它仍然看起来很酷\ m / \ m /
strCorpCodeTemp.Value = "U" ' Value will equal "U "
strCorpCodeTemp.Value = "US0980" ' Value will equal "US"
PS。当我想知道＆＃34;它是否停止工作，或者只是我的ASDL连接缓慢时，它会帮助很多？＆＃34;

使用PowerShell将二进制文件上传到FTP服务器的最简单方法是使用WebClient.UploadFile：
$client = New-Object System.Net.WebClient
$client.Credentials = New-Object System.Net.NetworkCredential("username", "password")
$client.UploadFile("ftp://ftp.example.com/remote/path/file.zip", "C:\local\path\file.zip")
如果您需要更强的控件，WebClient不提供（如TLS / SSL加密等），请使用FtpWebRequest。简单的方法是使用Stream.CopyTo将FileStream复制到FTP流：
$request = [Net.WebRequest]::Create("ftp://ftp.example.com/remote/path/file.zip")
$request.Credentials = New-Object System.Net.NetworkCredential("username", "password")
$request.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile
$fileStream = [System.IO.File]::OpenRead("C:\local\path\file.zip")
$ftpStream = $request.GetRequestStream()
$fileStream.CopyTo($ftpStream)
$ftpStream.Dispose()
$fileStream.Dispose()
如果您需要监控上传进度，则必须自行复制内容：
$request = [Net.WebRequest]::Create("ftp://ftp.example.com/remote/path/file.zip")
$request.Credentials = New-Object System.Net.NetworkCredential("username", "password")
$request.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile
$fileStream = [System.IO.File]::OpenRead("C:\local\path\file.zip")
$ftpStream = $request.GetRequestStream()
$buffer = New-Object Byte[] 10240
while (($read = $fileStream.Read($buffer, 0, $buffer.Length)) -gt 0)
{
$ftpStream.Write($buffer, 0, $read)
$pct = ($fileStream.Position / $fileStream.Length)
Write-Progress `
-Activity "Uploading" -Status ("{0:P0} complete:" -f $pct) `
-PercentComplete ($pct * 100)
}
$fileStream.CopyTo($ftpStream)
$ftpStream.Dispose()
$fileStream.Dispose()

Goyuix's solution效果很好，但是如上所述它给了我这个错误：“使用HTTP代理时不支持请求的FTP命令。”
在$ftp.UsePassive = $true为我解决问题后添加此行：

您可以通过PowerShell简单地处理文件上传，就像这样。 完整的项目可以在Github https://github.com/edouardkombo/PowerShellFtp
上找到#Directory where to find pictures to upload
$Dir= 'c:\fff\medias\'
#Directory where to save uploaded pictures
$saveDir = 'c:\fff\save\'
#ftp server params
$ftp = 'ftp://10.0.1.11:21/'
$user = 'user'
$pass = 'pass'
#Connect to ftp webclient
$webclient = New-Object System.Net.WebClient
$webclient.Credentials = New-Object System.Net.NetworkCredential($user,$pass)
#Initialize var for infinite loop
$i=0
#Infinite loop
while($i -eq 0){
#Pause 1 seconde before continue
Start-Sleep -sec 1
#Search for pictures in directory
foreach($item in (dir $Dir "*.jpg"))
{
#Set default network status to 1
$onNetwork = "1"
#Get picture creation dateTime...
$pictureDateTime = (Get-ChildItem $item.fullName).CreationTime
#Convert dateTime to timeStamp
$pictureTimeStamp = (Get-Date $pictureDateTime).ToFileTime()
#Get actual timeStamp
$timeStamp = (Get-Date).ToFileTime()
#Get picture lifeTime
$pictureLifeTime = $timeStamp - $pictureTimeStamp
#We only treat pictures that are fully written on the disk
#So, we put a 2 second delay to ensure even big pictures have been fully wirtten in the disk
if($pictureLifeTime -gt "2") {
#If upload fails, we set network status at 0
try{
$uri = New-Object System.Uri($ftp+$item.Name)
$webclient.UploadFile($uri, $item.FullName)
} catch [Exception] {
$onNetwork = "0"
write-host $_.Exception.Message;
}
#If upload succeeded, we do further actions
if($onNetwork -eq "1"){
"Copying $item..."
Copy-Item -path $item.fullName -destination $saveDir$item
"Deleting $item..."

}
}

您可以使用此功能：
function SendByFTP {
param (
$userFTP = "anonymous",
$passFTP = "anonymous",
[Parameter(Mandatory=$True)]$serverFTP,
[Parameter(Mandatory=$True)]$localFile,
[Parameter(Mandatory=$True)]$remotePath
)
if(Test-Path $localFile){
$remoteFile = $localFile.Split("\")[-1]
$remotePath = Join-Path -Path $remotePath -ChildPath $remoteFile
$ftpAddr = "ftp://${userFTP}:${passFTP}@${serverFTP}/$remotePath"
$browser = New-Object System.Net.WebClient
$url = New-Object System.Uri($ftpAddr)
$browser.UploadFile($url, $localFile)
}
else{
Return "Unable to find $localFile"
}
}
此功能通过 FTP 发送指定的文件。 您必须使用以下参数调用该函数：
例如：
SendByFTP -userFTP "USERNAME" -passFTP "PASSWORD" -serverFTP "MYSERVER" -localFile "toto.zip" -remotePath "path/on/the/FTP/"
