字符串整形
从网上拿到hosts记录,然后将它整形输出成address=/www.google.com/127.0.0.1这种格式。
第一个办法有点偷懒,只找出URL列,然后手动在最后加上IP地址。误打误撞学到了Trim的特殊之处。
第二个办法老老实实把URL列和IP列交换位置,然后输出。
<#方法一#> $result = (Invoke-WebRequest -Uri 'https://raw.githubusercontent.com/vokins/yhosts/master/hosts').content -split "`n" ($result | Select-String -Pattern "^127.0.0.1").Line | foreach { 'address=/' + $_.TrimStart('.1270').TrimStart() + '/127.0.0.1' } <#方法二#> $result = (Invoke-WebRequest -Uri 'https://raw.githubusercontent.com/vokins/yhosts/master/hosts').content -split "`n" ($result | Select-String -Pattern "^127.0.0.1").Line | foreach { 'address=/' + ($_ -split " ")[1] + "/" + ($_ -split " ")[0] }
将诸如"google.com": 1,这样格式的文本整形成server=/google.com/127.0.0.1#5353输出
$result = (Invoke-WebRequest -Uri 'https://raw.githubusercontent.com/1265578519/PAC/master/abc.pac').content -split "`n" ($result | Select-String -Pattern "`".+`":\s1").Line.Trim('",1: ') | foreach { 'server=/' + $_ + "/127.0.0.1#5353" }
将诸如apnic|CN|ipv4|203.34.39.0|256|20110414|allocated这样格式的文本整形输出成192.168.1.0/24
$result = (Invoke-WebRequest -Uri 'http://ftp.apnic.net/stats/apnic/delegated-apnic-latest').content -split "`n" ($result | Select-String -Pattern ".+CN[|]ipv4[|].+").Line | foreach { '-A SHADOWSOCKS -d ' + $_.split('|')[3] + '/' + (32 - [math]::log($_.split('|')[4]) / [math]::Log(2)) + ' -j RETURN' }
