PowerShell与PowerShell ISE之间的不同行为

Question

I have a script like this:

Write-Host "Create RabbitMQ infrastructure..."

$rabbitHost = "http://my.company.com:15672"
$serverPort = 12345
$prefix = "unit"

$user = "test"
$pass = "test"

$secpasswd = ConvertTo-SecureString $pass -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential ($user, $secpasswd)

$exchanges = ("MyExchange")

$exchanges | foreach {
    Write-Host "Create $_"

    $body = @{
        type    = "direct"
        durable = "true"
    }

    $json = $body | ConvertTo-Json

    try{
        $url = "$rabbitHost/api/exchanges/%2f/$prefix" + "_" + "$serverPort" + "_" + $_
        Invoke-RestMethod $url -Body $json -Method Put -Credential $cred -ContentType 'application/json'
    } catch {$_.Exception}
}

Everything fine, when I launch it from PowerShell ISE, but when I run it from PowerShell I get an error:

The remote server returned an error: (405) Method Not Allowed.

I know, that it can be somehow connected with RabbitMq, but I don't see how, because it is just a simple request.

Can you help me find a root cause of these differences?

I wasn't able to reproduce this locally but after some further digging I found this post which refers to another post with more information regarding issues with the %2f URL-encoded character (/).

The first post I referenced likely is the issue you were experiencing where the %2f is decoded before the request is made therefore changing the way the URL is interpreted. Note that the %2f refers to the default virtual host (see RabbitMQ api documentation).
