map示例：value为数组

package main

import(
    "fmt"
)

func main(){
    var yk = make(map[string][]string)
    yk["one"] = []string{"a123", "a456", "a789"}

    fmt.Println("yk[one] len = ", len(yk["one"]))

    i := len(yk["one"])
    for j:=0; j<i; j++{
        fmt.Println(yk["one"][j])   
    }

    yk["two"] = []string{"b123", "b456"}

    for k,v := range yk{
        fmt.Println("key:", k)
        fmt.Println("values:", v)

        for _, vs := range v {
            fmt.Println("value:", vs)               
        }
    }
}
