Question

我有一个网址www.example.com:1234/，我需要将上面的内容缩小为2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？

Answer 2

这是一种实现方法... [咧嘴]

# fake reading in a list of URLs
#    in real life, use Get-Content
$UrlList = @'
www.example.com:1234/
www3.example.net:9876
www.other.example.org:5678/
'@ -split [environment]::NewLine

$Regex = '^www.*?\.(?<Domain>.+):(?<Port>\d{1,}).*$'

$Results = foreach ($UL_Item in $UrlList)
    {
    $Null = $UL_Item -match $Regex

    [PSCustomObject]@{
        URL = $UL_Item
        Domain = $Matches.Domain
        OriginalPort = $Matches.Port
        Port = '00{0}' -f (-join $Matches.Port.ToString().SubString(1))
        }
    }

$Results

输出...

URL                        Domain           OriginalPort Port 
---                        ------           ------------ ---- 
www.example.com:1234/     example.com     1234         00234
www3.example.net:9876      example.net      9876         00876
www.other.example.org:5678/ other.example.org 5678         00678

注释掉或删除任何不需要的属性。 [咧嘴]

每个请求，一个简化的版本... [咧嘴]

$UserInput = 'www.example.com:1234/'

$Regex = '^www.*?\.(?<Domain>.+):(?<Port>\d{1,}).*$'

$Null = $UserInput -match $Regex

$Domain = $Matches.Domain
$Port = '00{0}' -f (-join $Matches.Port.SubString(1))

$Domain
$Port

输出...

example.com
00234

希望有帮助，

Answer 3

要改善James C.'s answer：

# Input URL string
$urlText = 'www.example.com:1234/'

# Prepend 'http://' and cast to [uri] (System.Uri), which
# parses the URL string into its constituent components.
$urlObj = [uri] "http://$urlText"

# Extract the information of interest
$domain = $urlObj.Host -replace '^www\.' # -> 'example.com'
$modifiedPort = '00' + $urlObj.Port.ToString().Substring(1) # -> '00234'

需要在PowerShell脚本中修剪URL
