Dark Sky APIを使ってみました！

PHPでリクエスト

サーバーの方はPHPを使っているので、以下のような感じでDark Sky APIにリクエストします。
JSONで返ってくるのでデコードします。

<?php
$url = "https://api.darksky.net/forecast/API_KEY/37.8267,-122.4233";
$contents = file_get_contents($url);
$decode = json_decode($contents, true);
print_r($decode);
?>

取得できるJSON

currentlyは現在の天気、minutelyは1分おきの0～60分まで、hourlyは1時間おきの0～48時間まで、dailyは1日おきの0～7日までの天気予報です。

各項目の意味

各項目の意味が分かりずらかったので翻訳を通してみました。
nearestStormDistanceやnearestStormBearing、cloudCover、ozoneは、日本ではあまり使わないですね。
