golang中读取ini配置

golang读取ini配置，推荐使用第三方库 go-ini

• 安装

go get  gopkg.in/ini.v1

• 测试代码
  简单封装下

package utils

import (
    "gopkg.in/ini.v1"
)

type IniParser struct {
    conf_reader *ini.File // config reader
}

type IniParserError struct {
    error_info string
}

func (e *IniParserError) Error() string { return e.error_info }

func (this *IniParser) Load(config_file_name string) error {
    conf, err := ini.Load(config_file_name)
    if err != nil {
        this.conf_reader = nil
        return err
    }
    this.conf_reader = conf
    return nil
}

func (this *IniParser) GetString(section string, key string) string {
    if this.conf_reader == nil {
        return ""
    }

    s := this.conf_reader.Section(section)
    if s == nil {
        return ""
    }

    return s.Key(key).String()
}

func (this *IniParser) GetInt32(section string, key string) int32 {
    if this.conf_reader == nil {
        return 0
    }

    s := this.conf_reader.Section(section)
    if s == nil {
        return 0
    }

    value_int, _ := s.Key(key).Int()

    return int32(value_int)
}

func (this *IniParser) GetUint32(section string, key string) uint32 {
    if this.conf_reader == nil {
        return 0
    }

    s := this.conf_reader.Section(section)
    if s == nil {
        return 0
    }

    value_int, _ := s.Key(key).Uint()

    return uint32(value_int)
}

func (this *IniParser) GetInt64(section string, key string) int64 {
    if this.conf_reader == nil {
        return 0
    }

    s := this.conf_reader.Section(section)
    if s == nil {
        return 0
    }

    value_int, _ := s.Key(key).Int64()
    return value_int
}

func (this *IniParser) GetUint64(section string, key string) uint64 {
    if this.conf_reader == nil {
        return 0
    }

    s := this.conf_reader.Section(section)
    if s == nil {
        return 0
    }

    value_int, _ := s.Key(key).Uint64()
    return value_int
}

func (this *IniParser) GetFloat32(section string, key string) float32 {
    if this.conf_reader == nil {
        return 0
    }

    s := this.conf_reader.Section(section)
    if s == nil {
        return 0
    }

    value_float, _ := s.Key(key).Float64()
    return float32(value_float)
}

func (this *IniParser) GetFloat64(section string, key string) float64 {
    if this.conf_reader == nil {
        return 0
    }

    s := this.conf_reader.Section(section)
    if s == nil {
        return 0
    }

    value_float, _ := s.Key(key).Float64()
    return value_float
}

测试代码

// config_read_test project main.go
package main

import (
    "fmt"
    "utils/ini"
)

func main() {
    fmt.Println("config read test!")

    ini_parser := utils.IniParser{}

    conf_file_name := "conf.ini"
    if err := ini_parser.Load("conf.ini"); err != nil {
        fmt.Printf("try load config file[%s] error[%s]\n", conf_file_name, err.Error())
        return
    }

    ip := ini_parser.GetString("", "test.ip")
    port := ini_parser.GetInt64("", "port")
    user_name := ini_parser.GetString("", "user_name")
    item_1 := ini_parser.GetInt64("", "item1")
    item_2 := ini_parser.GetInt64("", "item2")

    fmt.Printf("ip: %s, port: %d, user_name :%s, item1: %d, item2: %d\n", ip, port, user_name, item_1, item_2)

    ip = ini_parser.GetString("test", "ip")
    port = ini_parser.GetInt64("test", "port")
    user_name = ini_parser.GetString("test", "user_name")

    fmt.Printf("ip: %s, port: %d, user_name :%s\n", ip, port, user_name)
}

运行结果

config read test!
ip: , port: 0, user_name :, item1: 0, item2: 3333
ip: 127.0.0.1, port: 2202, user_name :test1
