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\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}]}
}
