gin中自定义路由日志的格式

package main

import (
	"fmt"
	"github.com/gin-gonic/gin"
	"net/http"
	"time"
)

func main() {
	router := gin.New()
	// LoggerWithFormatter middleware will write the logs to gin.DefaultWriter
	// By default gin.DefaultWriter = os.Stdout
	router.Use(gin.LoggerWithFormatter(func(param gin.LogFormatterParams) string {
		// your custom format
		return fmt.Sprintf("%s - [%s] \"%s %s %s %d %s \"%s\" %s\"\n",
			param.ClientIP,  // 客户端IP
			param.TimeStamp.Format(time.RFC3339),  // 请求时间
			param.Method,  // 请求方法
			param.Path,  // 请求路径
			param.Request.Proto,  // 请求协议
			param.StatusCode,  // 请求状态码
			param.Latency,  // 请求时长
			param.Request.UserAgent(),  // 请求
			param.ErrorMessage,
		)
	}))
	router.Use(gin.Recovery())
	router.GET("/ping", func(c *gin.Context) {
		c.String(200, "pong")
	})
	router.POST("/string", func(context *gin.Context) {
		context.JSON(http.StatusOK, "OK")
	})
	router.Run("192.168.110.20:3000")
}
