Dev*_*Dev 2 json go unmarshalling
我正在努力学习围棋。我正在编写一个简单的程序来从 GoLang 的 JSON 文件中获取值。
package main
import (
"encoding/json"
"fmt"
"io/ioutil"
"os"
)
type bands struct {
id string `json:"id"`
name string `json:"name"`
location string `json:"location"`
year string `json:"year"`
}
func main() {
bands := getBands()
fmt.Println(bands)
}
func getBands() []bands {
raw, err := ioutil.ReadFile("../data/bands.json")
if err != nil {
fmt.Println(err.Error())
os.Exit(1)
}
var c []bands
json.Unmarshal(raw, &c)
return c
}
另外,下面是我的 JSON 文件:
[{"id":"1","name": "The Beatles","location": "NY","year": "2012"},
{"id":"2","name": "Nirvana","location": "NY","year": "2010"},
{"id":"3","name": "Metallica","location": "NY","year": "1980"}]
当我运行文件时,我得到空白值。
谢谢您的帮助。
