問題の JSON 文字列は次のようになります。
{
"development":{
"connector":[
{"id":"connector-server-1", "host":"127.0.0.1", "port":4050, "wsPort":3050},
{"id":"connector-server-2", "host":"127.0.0.1", "port":4051, "wsPort":3051},
{"id":"connector-server-3", "host":"127.0.0.1", "port":4052, "wsPort":3052}
],
"chat":[
{"id":"chat-server-1", "host":"127.0.0.1", "port":6050},
{"id":"chat-server-2", "host":"127.0.0.1", "port":6051},
{"id":"chat-server-3", "host":"127.0.0.1", "port":6052}
],
"gate":[
{"id": "gate-server-1", "host": "127.0.0.1", "wsPort": 3014}
]
},
"production":{
"connector":[
{"id":"connector-server-1", "host":"127.0.0.1", "port":4050, "wsPort":3050},
{"id":"connector-server-2", "host":"127.0.0.1", "port":4051, "wsPort":3051},
{"id":"connector-server-3", "host":"127.0.0.1", "port":4052, "wsPort":3052}
],
"chat":[
{"id":"chat-server-1", "host":"127.0.0.1", "port":6050},
{"id":"chat-server-2", "host":"127.0.0.1", "port":6051},
{"id":"chat-server-3", "host":"127.0.0.1", "port":6052}
],
"gate":[
{"id": "gate-server-1", "host": "127.0.0.1", "wsPort": 3014}
]
}
}
そして、次のようなコードで解析したい:
package config
import(
"sync"
"io/ioutil"
"encoding/json"
"errors"
"log"
)
type Service struct {
Id string `json:"id"`
Host string `json:"host"`
Port uint `json:"port"`
QueryPort uint `json:"queryPort"`
WsPort uint `json:"wsPort"`
ServiceType string
}
type Config struct {
Services []Service
Master Service
Mutex sync.RWMutex
}
func LoadServers(filepath, env string) (*Config, error) {
// 读取文件
content, err := ioutil.ReadFile(filepath)
if err != nil {
return nil, err
}
configs := make(map[string]map[string][]Service, 0)
err = json.Unmarshal(content, configs)
if err != nil {
return nil, err
}
}
私のコードは、この JSON 文字列をmap[string]map[string][]Service
.
しかし、それはエラーを示しています:
json: Unmarshal(non-pointer map[string]map[string][]config.Service)
