go:gin输出日志文件方式

背景

我们运行服务端程序，日志直接会打印，本文介绍如何将服务端日志输出到日志文件

代码

package main

import (
	"io"
	"os"

	"github.com/gin-gonic/gin"
)

func main() {

	// Logging to a file.
	f, _ := os.Create("gin.log")
	gin.DefaultWriter = io.MultiWriter(f)

	// Use the following code if you need to write the logs to file and console at the same time.
	// gin.DefaultWriter = io.MultiWriter(f, os.Stdout)

	router := gin.Default()
	router.GET("/ping", func(c *gin.Context) {
		c.String(200, "pong")
	})

	router.Run(":8080")
}

运行程序之后服务端没有任何信息输出

再看当前路径下。

创建出来一个gin.log的文件

查看日志文件内容

[GIN-debug] [WARNING] Creating an Engine instance with the Logger and Recovery middleware already attached.

[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
 - using env:    export GIN_MODE=release
