Let's try Qiita api v2 via curl of powershell

powershellにもcurlがあることを知りQiita apiを試してみた。
curlはInvoke-WebRequestのAliasなのでInvoke-WebRequestを試してみたといった方が正確なのだろう。
受け取ったJSON形式のデータはconvertfrom-jsonでPSCustomObjectの配列に変換する。

PS >get-command  curl

scriptにしておく。

qiita.ps1

$url = 'https://qiita.com/api/v2/items?page=1&per_page=20'
$r = curl -URI $url
$c = ($r.content | convertfrom-json )
$i = 0
foreach ( $a in $c ){
    Write-Host "[${i}]"  ${a}.title
    $i ++
}

apiの利用には「1時間に60回まで」など制限事項があるので注意方。
