需要修剪powershell脚本中的url

我有一个URL

www.example.com:1234/

，我需要将上面的内容精简为两个变量：

example.com

00234

• 端口的第一位数字将替换为

  00

---

这可以在PowerShell中实现吗？

这里有一种方法。。。[咧嘴笑]

[uri]$url = 'www.example.com:1234/'

$Value1 = ($url.Scheme).Replace('www.','')
$Value2 = "00" + ($url.AbsolutePath).Substring(1).TrimEnd('/')

注释掉或删除任何不需要的属性。[咧嘴笑]

根据请求，简化版本。。。[咧嘴笑]

希望有帮助，
