GO JSONのパース方法についての備忘録

31 min read

はじめに

ネストが深くて配列もあるJSONのパース方法に悩んだので備忘録として残します。

環境

  • macOS Monterey 12.3.1
  • Go 1.18.1

パースしようとしたJSON

YahooFinanceAPIのレスポンスを例に説明していきます。 構造としては"quoteResponse"の中に"error","result"があり、 "result"は配列でその中には"ask"〜"twoHundredDayAverageChangePercent"があります。

JSONのレスポンス例

値を出力してみる

実際に値を取り出す際の実行例を示します。 値の取り出し方については方法1、方法2共に同じです。

試してみるときはあらかじめ「JSONのレスポンス例」で示したデータをmain.goと同じ階層に「test.json」として保存しておいてください。
