Go-json解码到结构体详解编程语言

废话不多说，直接干就得了，上代码

package main 
 
import ( 
	"encoding/json" 
	"fmt" 
) 
 
type IT struct { 
	Company  string   `json:"company"`   
	Subjects []string `json:"subjects"` 
	IsOk     bool     `json:"isok"` 
	Price    float64  `json:"price"` 
} 
 
func main() { 
	jsonBuf := ` 
	{ 
		"company": "itcast", 
		"subjects": [ 
			"Go", 
			"C++", 
			"Python", 
			"Test" 
		], 
		"isok": true, 
		"price": 666.666 
	} 
	` 
	var tmp IT 
	err := json.Unmarshal([]byte(jsonBuf), &tmp) 
	if err != nil { 
		fmt.Println("err=", err) 
		return 
	} 
	fmt.Println("tmp=", tmp) //tmp= {itcast [Go C++ Python Test] true 666.666} 
	 
        //fmt.Printf("tmp=%+v/n", tmp) //tmp={Company:itcast Subjects:[Go C++ Python Test] IsOk:true Price:666.666} 
	 
} 

package main 
 
import ( 
	"encoding/json" 
	"fmt" 
) 
 
type JsonServer struct { 
	ServerName string 
	ServerIP   string 
} 
 
type JsonServers struct { 
	Servers []JsonServer 
} 
 
func main() { 
	var s JsonServers 
	str := `{"servers":[{"serverName":"Shanghai_VPN","serverIP":"127.0.0.1"},{"serverName":"Beijing_VPN","serverIP":"127.0.0.2"}]}` 
	json.Unmarshal([]byte(str), &s) 
 
	fmt.Println(s)  //{[{Shanghai_VPN 127.0.0.1} {Beijing_VPN 127.0.0.2}]} 
}
