我想使用下面的代码从过滤的JSON中提取IP：
$curl = Invoke-WebRequest -Method Get -Uri "http://urltojson.com/file.json" $curl2 = $curl.Content.replace("Script", "Script_").replace("iphone", "iphone_").replace("android", "android_").replace("ipad","ipad_") | ConvertFrom-Json $curl3 = $curl2 | Where-Object {$_.Name -eq "/Common/cloudfront_nets"} | Select-Object -ExpandProperty data $curl3 [System.Collections.ArrayList]$curl3[0] = $curl3 $curl3[1] 其中返回以下内容
13.59.250.0 255.255.255.192：地区：us-east-2-service：CLOUDFRONT
52.57.254.0 255.255.255.0：地区：欧盟中心一服务：CLOUDFRONT
54.182.0.0 255.255.0.0：region：GLOBAL-service：CLOUDFRONT
52.212.248.0 255.255.255.192：地区：欧盟西部1服务：CLOUDFRONT
205.251.250.0 255.255.254.0：region：GLOBAL-service：CLOUDFRONT
35.162.63.192 255.255.255.192：地区：us-west-2-service：CLOUDFRONT
13.32.0.0 255.254.0.0：region：GLOBAL-service：CLOUDFRONT
205.251.254.0 255.255.255.0：region：GLOBAL-service：CLOUDFRONT
我努力简单地输出IP（没有子网掩码）
任何人都可以帮忙吗？
尝试：

给予@ J-barnaby积分第一个正确的答案，较短的位（假设$curl3[1]包含您需要格式化的输出数据）将如下所示：
# split the text into array of strings on line breaks and filter empty lines $output = $curl3[1] -split "`r`n" | ? {$_} # process each line $addresses = foreach ($line in $output) { # further break each line into space delimited words, selecting first word $line.Split(' ')[0] } # output the resulting list $addresses
