Echo

Build Status Go Go Report Card

Echo is a fast and unfancy web framework for Go (Golang). Up to 10x faster than the rest.

This package need >= go 1.13

Features

  • Optimized HTTP router which smartly prioritize routes.
  • Build robust and scalable RESTful APIs.
  • Run with standard HTTP server or FastHTTP server.
  • Group APIs.
  • Extensible middleware framework.
  • Define middleware at root, group or route level.
  • Handy functions to send variety of HTTP responses.
  • Centralized HTTP error handling.
  • Template rendering with any template engine.
  • Define your format for the logger.
  • Highly customizable.

Quick Start

Installation
$ go get github.com/webx-top/echo
Hello, World!

Create server.go

package main

import (
	"net/http"
	"github.com/webx-top/echo"
	"github.com/webx-top/echo/engine/standard"
)

func main() {
	e := echo.New()
	e.Get("/", func(c echo.Context) error {
		return c.String("Hello, World!", http.StatusOK)
	})
	e.Run(standard.New(":1323"))
}

Start server

$ go run server.go

Browse to http://localhost:1323 and you should see Hello, World! on the page.

Routing
e.Post("/users", saveUser)
e.Get("/users/:id", getUser)
e.Put("/users/:id", updateUser)
e.Delete("/users/:id", deleteUser)
e.Get("/user/<id:[\\d]+>", getUser)
Path Parameters
func getUser(c echo.Context) error {
	// User ID from path `users/:id`
	id := c.Param("id")
	// or id := c.Paramx("id").Uint64()
}
Query Parameters

/show?team=x-men&member=wolverine

func show(c echo.Context) error {
	// Get team and member from the query string
	team := c.Query("team")
	member := c.Query("member")
	age := c.Queryx("age").Uint()
}
Form application/x-www-form-urlencoded

POST /save

name value
name Joe Smith
email joe@labstack.com 
func save(c echo.Context) error {
	// Get name and email
	name := c.Form("name")
	email := c.Form("email")
	age := c.Formx("age").Uint()
}
Form multipart/form-data

POST /save

name value
name Joe Smith
email joe@labstack.com
avatar avatar 
func save(c echo.Context) error {
	// Get name and email
	name := c.Form("name")
	email := c.Form("email")

	//------------
	// Get avatar
	//------------
	_, err := c.SaveUploadedFile("avatar","./")
	return err
}
Handling Request
  • Bind JSON or XML payload into Go struct based on Content-Type request header.
  • Render response as JSON or XML with status code.
type User struct {
	Name  string `json:"name" xml:"name"`
	Email string `json:"email" xml:"email"`
}

e.Post("/users", func(c echo.Context) error {
	u := new(User)
	if err := c.MustBind(u); err != nil {
		return err
	}
	return c.JSON(u, http.StatusCreated)
	// or
	// return c.XML(u, http.StatusCreated)
})
Static Content

Server any file from static directory for path /static/*.

e.Use(mw.Static(&mw.StaticOptions{
	Root:"static", //存放静态文件的物理路径
	Path:"/static/", //网址访问静态文件的路径
	Browse:true, //是否显示文件列表
}))
Middleware
// Root level middleware
e.Use(middleware.Log())
e.Use(middleware.Recover())

// Group level middleware
g := e.Group("/admin")
g.Use(middleware.BasicAuth(func(username, password string) bool {
	if username == "joe" && password == "secret" {
		return true
	}
	return false
}))

// Route level middleware
track := func(next echo.HandlerFunc) echo.HandlerFunc {
	return func(c echo.Context) error {
		println("request to /users")
		return next.Handle(c)
	}
}
e.Get("/users", func(c echo.Context) error {
	return c.String("/users", http.StatusOK)
}, track)

e.Get("/setcookie", func(c echo.Context) error {
	c.SetCookie("uid","1")
	return c.String("/setcookie: uid="+c.GetCookie("uid"), http.StatusOK)
})
