如何解组 json 数组？

Question

当我解组 json 数组时出现问题。

我该如何纠正？代码是：http : //play.golang.org/p/AtU9q8Hlye

package main

import (

    "encoding/json"

    "fmt"

)

type Server struct {

    ServerName string

    ServerIP   string

}

type Serverslice struct {

    Name    string

    Servers []Server

}

func main() {

    var s []Serverslice

    str := `{"name":"dxh","servers":[{"serverName":"VPN0","serverIP":"127.0.0.1"},{"serverName":"Beijing_VPN","serverIP":"127.0.0.2"}],

        "name":"dxh1,"servers":[{"serverName":"VPN1","serverIP":"127.0.0.1"},{"serverName":"Beijing_VPN","serverIP":"127.0.0.2"}]}`

    json.Unmarshal([]byte(str), &s) //the wrong line.....................

    fmt.Println(len(s))

}
