golang基础-beego读取配置、log日志输出

beego读取配置文件

配置文件内容如下:

[server]
listen_ip = "0.0.0.0"
listen_port = 8888

[logs]
log_level=debug
log_path=./logs/logagent.log

[collect]
log_path=D:projectlogslogagent.log
topic=nginx_log
chan_size=100

通过代码读取配置文件

package main

import (
    "fmt"
    "github.com/astaxie/beego/config"
)

func main() {
    conf,err := config.NewConfig("ini","logagent.conf")
    if err != nil {
        fmt.Println("new config failed,err:",err)
        return
    }

    port,err:= conf.Int("server::listen_port")
    if err != nil {
        fmt.Println("read server:port failed,err)
        return
    }

    fmt.Println("port:",port)

    log_level := conf.String("logs::log_level")
    if len(log_level) == 0 {
        log_level = "debug"
    }

    fmt.Println("log_level:",log_level)

    log_path := conf.String("collect::log_path")
    fmt.Println("log_path:",log_path)
}

输出如下：

PS E:golanggo_prosrcsafly> go run demo.go
port: 8888
log_level: debug
log_path: D:projectlogslogagent.log
PS E:golanggo_prosrcsafly>

beego输出log文件日志

需要创建logs文件夹

package main

import (
    "encoding/json"
    "fmt"
    "github.com/astaxie/beego/logs"
)

func main() {
    //我测试如下3个路径均可
    config := make(map[string]interface{})
    // config["filename"] = "e:/golang/go_pro/logs/logcollect.log"
    // config["filename"] = "e://golang//go_pro//logs//logcollect.log"
    config["filename"] = "e:golanggo_prologslogcollect.log"
    config["level"] = logs.LevelDebug

    configStr,err := json.Marshal(config)
    if err != nil {
        fmt.Println("marshal failed,err)
        return
    }

    logs.SetLogger(logs.AdapterFile,string(configStr))

    logs.Debug("this is a test,my name is %s","stu01")
    logs.Trace("this is a trace,"stu02")
    logs.Warn("this is a warn,"stu03")
}

然后就会在logs文件夹中输出log文件logcollect.log
