您好,我有 json 数据,我将其解组为machines 切片。现在我正在寻找将每个hostname从 machinesslice struct 复制/附加到serviceStruct []hosts 。我尝试了几种方法,但努力迭代servicestruct 中的 []hosts 切片。
只是想知道将值从一个切片结构复制到另一个结构内的另一个切片值的最佳方法是什么。
package main
import (
"encoding/json"
"fmt"
)
type Machine struct {
hostname string
Ip string
Name string
}
type Host struct {
HostName string `json:"host_name"`
Vars Var `json:"vars"`
}
type Service struct {
ServiceName string `json:"service_name"`
Required bool `json:"required"`
Hosts []Host `json:"hosts"`
Vars Var `json:"vars"`
}
func main() {
machineInfo := `[{"dns":"1.1.1.1.eu-south-1.compute.amazonaws.com","ip":"1.1.1.1","name":"Machine-1"},{"dns":"1.1.1.2.eu-south-1.compute.amazonaws.com","ip":"1.1.1.2","name":"Machine-2"}]`
var machines []Machine
var mService *Service
//convert the json to byts slice and then
json.Unmarshal([]byte(machineInfo), &machines)
//Data is now add to the structs
for i, _ := range machines {
mService.Hosts = append(mService.Hosts, machines[i].hostname)
}
fmt.Printf("Machines : %v", mService)
data, _ := json.Marshal(mService)
fmt.Println(string(data))
}
