为什么powershell http服务器代码不能工作

$listener = New-Object System.Net.HttpListener
$listener.Prefixes.Add("http://localhost:8080/")
$listener.Start()

Write-Host "Server started. Listening for requests..."

while ($listener.IsListening) {
    $context = $listener.GetContext()
    $request = $context.Request
    $response = $context.Response

    $content = [System.Text.Encoding]::UTF8.GetBytes("Hello, World!")
    $response.ContentLength64 = $content.Length
    $response.OutputStream.Write($content, 0, $content.Length)
    $response.Close()
}

$listener.Stop()
