如何获得goconfig第三方包
在git shell中使用go get github.com/Unknwon/goconfig安装goconfig包
如何使用goconfig
package main
import (
"fmt"
"github.com/Unknwon/goconfig"
"log"
)
func main() {
cfg, err := goconfig.LoadConfigFile("config.ini")
if err != nil {
log.Println("读取配置文件失败[conf.ini]")
return
}
str, _ := cfg.GetValue(goconfig.DEFAULT_SECTION, "default_key")
fmt.Printf("%s\n", str)
}
goconfig包提供如下函数：
func SaveConfigFile(c *ConfigFile, filename string) (err error)
func LoadConfigFile(fileName string, moreFiles ...string) (c *ConfigFile, err error)
func (c *ConfigFile) Bool(section, key string) (bool, error)
func (c *ConfigFile) Float64(section, key string) (float64, error)
func (c *ConfigFile) GetKeyComments(section, key string) (comments string)
func (c *ConfigFile) GetSection(section string) (map[string]string, error)
func (c *ConfigFile) GetSectionComments(section string) (comments string)
func (c *ConfigFile) GetValue(section, key string) (string, error)
func (c *ConfigFile) Int64(section, key string) (int64, error)
func (c *ConfigFile) MustBool(section, key string, defaultVal ...bool) bool
func (c *ConfigFile) MustFloat64(section, key string, defaultVal ...float64) float64
func (c *ConfigFile) MustInt(section, key string, defaultVal ...int) int
func (c *ConfigFile) MustInt64(section, key string, defaultVal ...int64) int64
func (c *ConfigFile) MustValue(section, key string, defaultVal ...string) string
func (c *ConfigFile) SetKeyComments(section, key, comments string) bool
func (c *ConfigFile) SetSectionComments(section, comments string) bool
func (c *ConfigFile) SetValue(section, key, value string) bool
总的来说，goconfig包基本满足对ini等配置文件读取需求，当然该包还提供很多其他的特性，进一步的学习，请查看
