使用 WebClient 在 PowerShell 脚本中将 FTP 从二进制更改为 ascii [英] Changing FTP from binary to ascii in PowerShell script using WebClient

问题描述

简单的 PowerShell 脚本.它下载一个文件(二进制)没有问题.我需要它在ASCII中.

Simple PowerShell script. It downloads a file (in binary) with no issues. I need it in ascii.

$File = "c:	empftpfile.txt"
$ftp = "ftp://myusername:mypass@12.345.6.78/'report'";
$webclient = New-Object -TypeName System.Net.WebClient;
$uri = New-Object -TypeName System.Uri -ArgumentList $ftp;
$webclient.DownloadFile($uri, $File);

推荐答案

WebClient不支持ascii/text FTP模式.

The WebClient does not support ascii/text FTP mode.

使用 FtpWebRequest 而是设置 .UseBinary 为假.

Use FtpWebRequest instead and set .UseBinary to false.

$File = "c:	empftpfile.txt"
$ftp = "ftp://myusername:mypass@12.345.6.78/'report'";

$ftprequest = [System.Net.FtpWebRequest]::Create($ftp)

$ftprequest.Method = [System.Net.WebRequestMethods+Ftp]::DownloadFile
$ftprequest.UseBinary = $false

$ftpresponse = $ftprequest.GetResponse()

$responsestream = $ftpresponse.GetResponseStream()

$targetfile = New-Object IO.FileStream($File, [IO.FileMode]::Create)

$responsestream.CopyTo($targetfile)

$targetfile.close()

请注意，WebClient 在内部使用 FtpWebRequest，但不公开其 .UseBinary 属性.

Note that the WebClient uses the FtpWebRequest internally, but does not expose its .UseBinary property.
