利用Golang解析json数据的方法示例

var jsonBlob = []byte(`[ 
 {"Name": "Platypus", "Order": "Monotremata"}, 
 {"Name": "Quoll", "Order": "Dasyuromorphia"} 
]`) 
type Animal struct { 
 Name string 
 Order string 
} 
var animals []Animal 
err := json.Unmarshal(jsonBlob, &animals) 
if err != nil { 
 fmt.Println("error:", err) 
} 
fmt.Printf("%+v", animals)

func main() {
 jsonData := []byte(`{"A":3,"B":3,"C":5,"D":5}`)
 var a map[string]int
 json.Unmarshal(jsonData, &a)
 fmt.Printf("%+v\n", a)
}

func main() {
 jsonData := []byte(`["a","b","c","d","e"]`)
 var a []string
 json.Unmarshal(jsonData, &a)
 fmt.Printf("%+v\n", a)
}

[
 0=>"a",
 1=>"b",
 2=>"c",
 3=>"d",
 4=>"e"
]

func main() {
 jsonData := []byte(`["a","b","c","d","e"]`)
 var a []string
 json.Unmarshal(jsonData, &a)
 
 newData := make(map[int]string)
 for k, v := range a {
 newData[k] = v
 }
 
 fmt.Printf("%+v\n", newData)
}
