一，zap库安装
$ go get -u go.uber.org/zap
go: added go.uber.org/multierr v1.11.0
go: added go.uber.org/zap v1.27.0二，代码
accesslog

}//重写 Write([]byte) (int, error) 方法
func(w responseWriter)Write(b []byte)(int, error) {//向一个bytes.buffer中写一份数据来为获取body使用w.b.Write(b)//完成gin.Context.Writer.Write()原有功能return w.ResponseWriter.Write(b)

}routes.go 启用日志中间件
package routesimport ("embed""fmt""github.com/gin-gonic/gin""html/template""io/fs""mediabank/controller""mediabank/global""mediabank/middleware""net/http""runtime/debug""time"
)func Routes(embedFs embed.FS) *gin.Engine {router := gin.Default()//全局使用访问日志//router.Use(middleware.AccessLog())//处理找不到路由router.NoRoute(HandleNotFound)router.NoMethod(HandleNotFound)//处理发生异常router.Use(Recover)//1, 加载模板文件tmpl := template.Must(template.New("").ParseFS(embedFs, "templates/**/*.html"))router.SetHTMLTemplate(tmpl)//2, 加载静态文件fp, _ := fs.Sub(embedFs, "static")router.StaticFS("/static", http.FS(fp))//3,加载favicon//static是存放favicon.ico的目录faviconHandler := http.FileServer(http.FS(fp))router.GET("/favicon.ico", func(c *gin.Context) {faviconHandler.ServeHTTP(c.Writer, c.Request)})//media,使用自定义的访问日志中间件media := controller.NewMediaController()mediaGroup := router.Group("/media").Use(middleware.AccessLog()){mediaGroup.GET("/detail", media.Detail)mediaGroup.GET("/list", media.List)mediaGroup.GET("/user", media.User)}return router
}三，测试效果
