Go-json解码到结构体

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
", 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}]}
}
