go的json操作

package main import ( "encoding/json" "fmt" ) type Server struct { ServerName string ServerIp string } type Serverslice struct { Servers []Server } func main() { //解析一个json var s Serverslice str := `{"servers":[{"serverName":"GZZ_VPN","serverIP":"127.0.0.3"},{"serverName":"SZ_VPN","serverIP":"127.0.0.4"}]}` //这里是json_decode json.Unmarshal([]byte(str), &s) fmt.Println(s) //添加一个json s.Servers = append(s.Servers, Server{ServerName: "Shanghai_VPN", ServerIp: "127.0.0.1"}) s.Servers = append(s.Servers, Server{ServerName: "Beijing_VPN", ServerIp: "127.0.0.2"}) //这里相当于json_encode b, err := json.Marshal(s) if err != nil { fmt.Println("json err:", err) } fmt.Println(string(b)) }
