快速开始

Echo建议的使用方式是Gomod，因此我们需要把项目建立在$GOPATH之外

例子：简单的Echo服务

{% tabs %} {% tab title="main.go" %}

package main

import (
	"net/http"

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

func main() {
	// Echo instance
	e := echo.New()

	// Middleware
	e.Use(middleware.Logger())
	e.Use(middleware.Recover())

	// Routes
	e.GET("/", hello)

	// Start server
	e.Logger.Fatal(e.Start("localhost:8080"))
}

// Handler
func hello(c echo.Context) error {
	return c.String(http.StatusOK, "Hello, World!")
}
