棋牌项目Go的日志打印问题

• 项目使用 go work 管理
• 模块 github.com/spf13/viper 通过 application.yml 加载配置

• application.yml 配置的日志等级为 debug
  • 应用名为 user

appName: user
log:
  level: DEBUG

配置日志模块

• 安装日志模块: github.com/charmbracelet/log
• 封装日志, 以便直接调用
  • common/logs/logs.go

package logs

import (
    "common/config"
    "os"
    "time"

    "github.com/charmbracelet/log"
)

var logger *log.Logger

func InitLog(appName string) {
    logger = log.NewWithOptions(os.Stderr, log.Options{
        Prefix:          appName,
        ReportTimestamp: true,
        TimeFormat:      time.DateTime,
        Level:           log.InfoLevel,
    })
	
    if config.Conf.Log.Level == "DEBUG" {
        logger.SetLevel(log.DebugLevel)
    }
}

func Fatal(format string, values ...any) {
    if len(values) == 0 {
        logger.Fatal(format)
    } else {
        logger.Fatal(format, values...)
    }
}

func Info(format string, values ...any) {
	if len(values) == 0 {
        logger.Fatal(format)
    } else {
        logger.Fatalf(format, values...)
    }
}

func Debug(format string, values ...any) {
    if len(values) == 0 {
        logger.Debug(format)
    } else {
        logger.Debug(format, values...)
    }
}

func Error(format string, values ...any) {
    if len(values) == 0 {
        logger.Error(format)
    } else {
        logger.Error(format, values...)
    }
}

• 调用日志
  • main.go

package main

import (
	"common/config"
	"common/logs"

	"github.com/charmbracelet/log"
)

func main() {
	config.InitConfig("./application.yml")
	logs.InitLog("test")
	log.Info("Hello, World!")
	log.Error("Hello, World!")
	log.Info("Hello, World!")
	a := 1
	go func() {
		log.Info(a)
	}()
	select {}
}

• 运行命令, 可以看到日志被打印出来
