用于清除消息队列的 PowerShell 脚本不起作用

Question

我从 PowerShell 库下载了一个脚本，该脚本应该用于清除 RabbitMQ 中的消息队列。但是，我遇到了一些无法修复的错误。所以我的脚本如下：

function Clear-RabbitMQQueue
{
[CmdletBinding(SupportsShouldProcess=$false, ConfirmImpact="High")]
Param
(
    # Name of RabbitMQ Virtual Host.
    [parameter(Mandatory=$false, ValueFromPipelineByPropertyName=$true, Position=0)]
    [Alias("test_test", "vhost")]
    [string]$VirtualHost = $defaultVirtualHost,

    # The name of the queue from which to receive messages
    [parameter(Mandatory=$false, ValueFromPipelineByPropertyName=$true, Position=1)]
    [Alias("test_Test", "QueueName")]
    [string]$Name,

    # Name of the computer hosting RabbitMQ server. Defalut value is localhost.
    [parameter(ValueFromPipelineByPropertyName=$true, Position=2)]
    [Alias("test_servername", "HostName")]
    [string]$BaseUri,

    # Credentials to use when logging to RabbitMQ server.
    [Parameter(Mandatory=$false)]
    [PSCredential]$Credentials
)

Begin
{
}
Process
{
    if ($pscmdlet.ShouldProcess("server: $BaseUri/$VirtualHost", "purge queue $Name"))
    {
        $url = Join-Path $BaseUri "/#/queues/$([System.Web.HttpUtility]::UrlEncode($VirtualHost))/$([System.Web.HttpUtility]::UrlEncode($Name))"
        Write-Verbose "Invoking REST API: $url"

        $result = Invoke-RestMethod $url -Credential $Credentials -AllowEscapedDotsAndSlashes -DisableKeepAlive -ErrorAction Continue -Method Delete
    }
}
End
{
}
}

Clear-RabbitMQQueue

我收到的错误是：

有人能帮我修复这些错误吗？很紧急！

更新

新代码：

Function Clear-RabbitMQQueue()
{

-virtualHost CCS_Loans2Go_DEV -Name computershare.infiniti.integration.test.Computershare.Infiniti.FormProcessing.Contracts:IFormSubmittedEvent.FormPrimedEvent.event -HostName rabbitmq-dev.emea.cshare.net

}

Clear-RabbitMQQueue

我收到的错误是：

-virtualHost : The term '-virtualHost' is not recognized as the name of a 
cmdlet, function, script file, or operable program. Check 
the spelling of the name, or if a path was included, verify that the path is 
correct and try again.
