go-gin (youtebu自学) - 第四课 --自定义logger输出到文件

自定义logger输出到文件

• 新建文件夹log
• server.go

  package main
  
  import (
  	"io"
  	"learn-gin/controller"
  	"learn-gin/middleware"
  	"learn-gin/service"
  	"net/http"
  	"os"
  
  	"github.com/gin-gonic/gin"
  )
  
  var (
  	blogService    service.BlogService       = service.New()
  	blogController controller.BlogController = controller.New(blogService)
  )
  // +
  func setupLogOutput() {
  	f, _ := os.Create("log/learn-gin.log")
  	gin.DefaultWriter = io.MultiWriter(f, os.Stdout)
  }
  
  func main() {
  	setupLogOutput() // +
  
  	server := gin.New()
  
  	server.Use(gin.Recovery(), middleware.Logger())
  
  	server.GET("blogs", func(c *gin.Context) {
  		c.JSON(http.StatusOK, blogController.FindAll())
  	})
  
  	server.POST("blogs", func(c *gin.Context) {
  		c.JSON(http.StatusCreated, blogController.Save(c))
  	})
  
  	server.Run(":8080") //启动服务端口，端口参数可选
  }
