[英]golang : Unmarshal: json: cannot unmarshal array into Go value of type main.MonitorServerInfo
json: cannot unmarshal array into Go value of type json:无法将数组解组为类型的Go值
config json: 配置json:
{
"monitor_servers_info":[
{
"server_info":{
"host":"127.0.0.1",
"port":28081,
"magic":"magic0",
"params":"all",
"interval":10000
}
},
{
"server_info":{
"host":"127.0.0.1",
"port":28080,
"magic":"magic1",
"params":"all",
"interval":10000
}
}
],
"sentry_server":{
"host":"127.0.0.1",
"port":80
},
"deadtime":"110000"
}
and my golang code like this: 和我的golang代码是这样的:
type ServerInfo struct {
Host string `json:"host"`
Port int64 `json:"port"`
Magic string `json:"magic"`
Params string `json:"params"`
Interval int64 `json:"interval"`
}
type ServerInfoStrap struct {
ConnInfo ServerInfo `json:"server_info"`
}
type MonitorServerInfo struct {
Servers []ServerInfoStrap
}
type SentryServer struct {
Host string `json:"host"`
Port int64 `json:"port"`
}
type ConfigServer struct {
ServerInfo MonitorServerInfo `json:"monitor_servers_info"`
ConnServer SentryServer `json:"sentry_server"`
DeadTime string `json:"deadtime"`
}
json parse code : json解析代码:
func readFile(filename string) (config ConfigServer, err error) {
bytes, err := ioutil.ReadFile(filename)
if err != nil {
fmt.Println("ReadFile: ", err.Error())
return
}
//bytes, err = StripComments(bytes) //去掉注释
//if err != nil {
// log.Info("Failed to strip comments from json: %s\n", err)
// return
//}
//xxx := make(map[string]interface{})
fmt.Println(string(bytes))
err = json.Unmarshal(bytes, &config)
if err != nil {
fmt.Println("Unmarshal: ", err.Error())
return
}
fmt.Println(config)
return
}
Your MonitorServerInfo
type is the cause of the problem. 原因是您的
MonitorServerInfo
类型。 Get rid of it and it works: 摆脱它,它的工作原理是:
type ConfigServer struct {
ServerInfo []ServerInfoStrap `json:"monitor_servers_info"`
ConnServer SentryServer `json:"sentry_server"`
DeadTime string `json:"deadtime"`
}
