通过WebClient在FTP凭据中使用特殊字符(斜杠) [英] Using special characters (slash) in FTP credentials with WebClient

问题描述

我发现绝对是引起问题的密码.我的密码中有一个正斜杠，并且无法弄清楚该如何接受它.我已经尝试用%5B替换它.不能更改密码.

I have discovered it's definitely the password that is causing issues. I have a forward slash in my password and cannot figure out how to get this to accept it. I've already tried replacing it with %5B. Changing the password is not a possibility.

cd v:
$username = "*********"
$password = "*********"
$usrpass = $username + ":" + $password
$webclient = New-Object -TypeName System.Net.WebClient

function ftp-test 
{
    if (Test-Path v:\*.204)
    {
        $files = Get-ChildItem v:\ -name -Include *.204 | where { ! $_.PSIsContainer } #gets list of only the .204 files

        foreach ($file in $files)
        {
            $ftp = "ftp://$[e-mail]/IN/$file"
            Write-Host $ftp
            $uri = New-Object -TypeName System.Uri -ArgumentList $ftp
            $webclient.UploadFile($uri, $file)
        }
    }
}


ftp-test

运行上面的代码时，我得到

When I run the above code I get

Exception calling "UploadFile" with "2" argument(s): "An exception occurred during a WebClient request."
At line:13 char:34
+             $webclient.UploadFile <<<< ($uri, $file)
+ CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : DotNetMethodException

我不确定是什么问题.搜索带来了代理问题，但是我没有代理需要通过.

I'm not sure what the issue is. Searching has brought issue with proxies, but I have no proxy that I need to get through.

我可以使用ftp.exe手动上传文件，但是我宁愿在PowerShell中执行所有这些操作，而不是生成脚本来使用ftp.exe.

I can manually upload the file with ftp.exe, but I'd rather do all this in PowerShell if possible instead of generating a script to use ftp.exe with.

推荐答案

您必须 URL-编码特殊字符. 请注意，已编码的斜杠(/)是%2F，而不是%5B(即[).

You have to URL-encode the special characters. Note that encoded slash (/) is %2F, not %5B (that's [).

使用 :

$usrpass = $username + ":" + [System.Uri]::EscapeDataString($password)

---

或使用 WebClient.Credentials属性，并且您无需转义任何内容:

---

Or use the WebClient.Credentials property, and you do not need to escape anything:

$webclient.Credentials = New-Object System.Net.NetworkCredential($username, $password)

...

$ftp = "ftp://ftp.example.com/IN/$file"

---

与(Ftp)WebRequest类似:在我的PowerShell FTP脚本中转义@字符

---

Similarly for (Ftp)WebRequest: Escape the @ character in my PowerShell FTP script
