golang读取配置文件

golang使用viper包解析配置文件

 1 package main
 2 
 3 import (
 4     "fmt"
 5 
 6     "github.com/spf13/viper"
 7 )
 8 
 9 var Conf = &Config{}
10 
11 type RemoteAddress struct {
12     TestAddr       []string `mapstructure:"test_addr"`
13     ProductionAddr []string `mapstructure:"production_addr"`
14 }
15 
16 type HTTPConfig struct {
17     Address string `mapstructure:"address"`
18     Port    string `mapstructure:"port"`
19 }
20 
21 type RPCConfig struct {
22     Address string `mapstructure:"address"`
23     Port    string `mapstructure:"port"`
24 }
25 
26 type Server struct {
27     HTTP          HTTPConfig    `mapstructure:"http"`
28     RPC           RPCConfig     `mapstructure:"rpc"`
29     RemoteAddress RemoteAddress `mapstructure:"remote_address"`
30 }
31 
32 type Client struct {
33     HTTP HTTPConfig `mapstructure:"http"`
34     RPC  RPCConfig  `mapstructure:"rpc"`
35 }
36 
37 type Config struct {
38     Server Server `mapstructure:"server"`
39     Client Client `mapstructure:"client"`
40 }
41 
42 func main() {
43     c := &Config{}
44     filename := "./conf.yaml"
45 
46     viper.SetConfigType("yaml")
47     viper.SetConfigFile(filename)
48 
49     err := viper.ReadInConfig()
50     if err != nil {
51         fmt.Println("read config is failed err:", err)
52     }
53 
54     err = viper.Unmarshal(c)
55     if err != nil {
56         fmt.Println("unmarshal config is failed, err:", err)
57     }
58 
59     fmt.Println("------", *c)
60 }
