擷取配置例子

package mainimport (    "flag"    "fmt"    "runtime"    "github.com/spf13/viper")type Config struct {    Base BaseConf `mapstructure:"base"`}type BaseConf struct {    pidfile   string `mapstructure:"pidfile"`}var (    Conf     *Config    confPath string)func init() {    flag.StringVar(&confPath, "d", "./", " set logic config file path")}func InitConfig() (err error) {    Conf = NewConfig()    viper.SetConfigName("logic") // 設定檔的名字    viper.SetConfigType("toml") // 設定檔的類型    viper.AddConfigPath(confPath) // 設定檔的路徑    if err := viper.ReadInConfig(); err != nil {        return err    }    if err := viper.Unmarshal(&Conf); err != nil {        panic(fmt.Errorf("unable to decode into struct：  %s \n", err))    }    return nil}func NewConfig() *Config {    return &Config{        Base: BaseConf{            Pidfile:   "/tmp/comet.pid",        },    }}# toml 檔案內容為[base]pidfile = "/tmp/logic.pid"
