【学习笔记】golang第三方库goconfig的使用

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：

• Variables

• func SaveConfigFile(c *ConfigFile, filename string) (err error)

• type ConfigFile

• func LoadConfigFile(fileName string, moreFiles ...string) (c *ConfigFile, err error)

• func (c *ConfigFile) AppendFiles(files ...string) error

• func (c *ConfigFile) Bool(section, key string) (bool, error)

• func (c *ConfigFile) DeleteKey(section, key string) bool

• 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) Int(section, key string) (int, 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) Reload() (err error)

• 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
