如何使用go echo中间件？

Question

我安装回声通过go get -u github.com/labstack/echo/v4它的包装在喜欢go.modmodule appgo 1.15require (    github.com/labstack/echo v3.3.10+incompatible    github.com/labstack/echo/v4 v4.2.0) 在 中，使用中间件作为server.gopackage appimport (    "github.com/labstack/echo/v4"    "github.com/labstack/echo/middleware")func main() {    e := echo.New()    e.Use(middleware.Logger())}它提醒 .其他中间件也无法使用。too few arguments in call to middleware.Logger

Answer 1

试试这个

package main

import (

    "net/http"

    "github.com/labstack/echo/v4"

    "github.com/labstack/echo/v4/middleware"

)

func main() {

    e := echo.New()

    e.Use(middleware.Logger())

    e.GET("/", func(c echo.Context) error {

        return c.String(http.StatusOK, "Hello World")

    })

    e.Logger.Fatal(e.Start(":9000"))

}

而在go.mod中只有它

module app

go 1.15

require github.com/labstack/echo/v4 v4.2.0
