【Golang】レスポンスのJsonをいじってみる

今回のゴール

Goでリクエストを投げてJson形式のレスポンスを受けとる。
ついでに任意のデータを画面に表示する

ソースコード

package main

import (
	"encoding/json"
	"fmt"
	"io/ioutil"
	"net/http"
)

func main() {
	url := "http://weather.livedoor.com/forecast/webservice/json/v1?city=110010"
	res, _ := http.Get(url)
	defer res.Body.Close()
	byteArr, _ := ioutil.ReadAll(res.Body)
	var weatherData WeatherData

	err := json.Unmarshal(byteArr, &weatherData)

	if err != nil {
		fmt.Println(err)
	}

	fmt.Println(weatherData.Description.Text)
}
