我有以下json哈希的json数组:
[
{
"name": "XXXX",
"address": "XXXX",
"keepalive": {
"thresholds": {
"warning": 30,
"critical": 100
},
"handlers": [
"XXXXX"
],
"refresh": 180
},
"subscriptions": [
"XXXX",
"XXXX",
"XXXX"
],
"version": "0.17.1",
"timestamp": 1486413490
},
{...},
{...},
...
]
我正在解析数组如下:
type Client struct {
Name string `json:"name"`
Address string `json:"address"`
PublicDNS string `json:"publicDNS"`
keepalive [] string `json:"keepalive"`
Subscriptions [] string `json:"subscriptions"`
Version string `json:"version"`
Timestamp int64 `json:"timestamp"`
}
type ClientResponse []Client
func getClients(body []byte) (*ClientResponse, error) {
var s = new(ClientResponse)
err := json.Unmarshal(body, &s)
if(err != nil){
fmt.Println("whoops:", err)
}
return s, err
}
func main() {
res,err := http.Get("http://xxxxx:4567/clients")
if err != nil{
panic(err.Error())
}
body,err := ioutil.ReadAll(res.Body)
if err != nil{
panic(err.Error())
}
s, err := getClients([]byte(body))
fmt.Println(s)
}
问题:变量s,包含所有数组。所以我怎么能得到所有数组的名称值?我应该做循环并获得我需要的价值吗?这是最好的方法吗?
答案 0 :(得分:1)
你必须循环它们。
names := make([]string, len(*s))
for i := range *s {
names[i] = (*s)[i].Name
}
顺便提一下,您的解组结构不正确。 keepalive
未导出,因此它不会被解组,即使它是,它也被定义为一个字符串片段,而JSON中的keepalive
字段是{{1}的对象}},thresholds
和handlers
字段
