英文:
How to range over nested struct in golang?
问题
我是你的中文翻译助手，以下是翻译好的内容：
我对Golang还不熟悉：
这是我定义的结构体：
type Name map[string]Infotype Info struct {Addresses string `json:"addresses"`Host map[string]Server `json:"host"`}type Server struct {Ipaddress string `json:"ip"`Status string `json:"status"`}var result Name
在解析JSON后，我得到了：
result = [user1: {192.168.98.0/26map[xx.user1.domain.com: {192.168.98.1 good}xx.user1.domain.com: {192.168.98.3 good}xx.user1.domain.com: {192.168.98.4 Bad}]}user2: {192.168.99.0/26map[xx.user2.domain.com: {192.168.99.1 good}]}]
如何遍历这个JSON，以获取特定用户的状态为"good"的ip地址？
我尝试这样做：
for j, _ := range result["user1"].Host {if a := result["user1"].Host[j].Status; a == "good" {//问题在于我不确定如何进一步扫描ip和状态//做一些操作}}
希望对你有帮助！

I am new to Golang:
These are my defined struct:
type Name map[string]Infotype Info struct {Addresses string `json:"addresses"`Host map[string]Server `json:"host"`}type Server struct {Ipaddress string `json:"ip"`Status string `json:"status"`}var result Name
after unmarshalling Json i get:
result = [user1:{192.168.98.0/26map[xx.user1.domain.com:{192.168.98.1 good}xx.user1.domain.com:{192.168.98.3 good}xx.user1.domain.com:{192.168.98.4 Bad}]}user2: {192.168.99.0/26map[xx.user2.domain.com:{192.168.99.1 good}]}]
How to range over this Json to get the ipaddress which has a status=="good" for the particular user ?
I am trying to do this way:
for j , _ := range result["user1"].Servers {if a := result["user1"].Servers[j]); a == "good" {//Problem is here I am not sure how to further scan the ip and status//do something
}
}}

我认为你想要的是：
for _ , i := range result {for _, j := range i.Host {if j.Status == "good" {server := j.Ip}}}
这段代码的作用是遍历result列表中的元素，然后遍历每个元素中的Host列表。如果某个Host的Status属性等于"good"，则将该Host的Ip属性赋值给变量server。
英文:
I think you want:
for _ , i := range result {for _, j := range i.Host {if j.Status == "good" {server := j.Ip}}}
