代码实例：

package main

    "encoding/json"
)

type Server struct {
    ServerName string
    ServerIP   string
}
type Serverslice struct {
    Servers []Server
}

    str := `{

                    }
                ]
            }`

    // 解析字符串为Json
    json.Unmarshal([]byte(str), &s)

    // 遍历Json
    for key, val := range s.Servers {

        // 打印索引和其他数据
        print(`Key：`, key, "\t")
        print(`Name：`, val.ServerName, "\t")
        println(`IP：`, val.ServerIP)
    }
