Echo微型 Web 框架
Echo 是一个用 Go 语言开发的快速 HTTP 路由器（零内存分配）和微型 Web 框架。
性能比较：
特性：
-
Zippy router.
-
Extensible middleware/handler, supports:
-
func(*echo.Context) -
http.Handler -
http.HandlerFunc -
func(http.ResponseWriter, *http.Request) -
func(*echo.Context) -
func(echo.HandlerFunc) echo.HandlerFunc -
func(http.Handler) http.Handler -
http.Handler -
http.HandlerFunc -
func(http.ResponseWriter, *http.Request) -
Middleware
-
Handler
-
-
Handy encoding/decoding functions.
-
支持静态文件处理
示例代码：
package main
import (
"net/http"
"github.com/labstack/echo"
mw "github.com/labstack/echo/middleware"
"github.com/rs/cors"
"github.com/thoas/stats"
)
type user struct {
ID string `json:"id"`
Name string `json:"name"`
}
var users map[string]user
func init() {
users = map[string]user{
"1": user{
ID: "1",
Name: "Wreck-It Ralph",
},
}
}
func createUser(c *echo.Context) {
u := new(user)
if c.Bind(u) {
users[u.ID] = *u
c.JSON(http.StatusCreated, u)
}
}
func getUsers(c *echo.Context) {
c.JSON(http.StatusOK, users)
}
func getUser(c *echo.Context) {
c.JSON(http.StatusOK, users[c.P(0)])
}
func main() {
e := echo.New()
//*************************//
// Built-in middleware //
//*************************//
e.Use(mw.Logger)
//****************************//
// Third-party middleware //

// https://github.com/rs/cors
e.Use(cors.Default().Handler)
// https://github.com/thoas/stats
s := stats.New()
e.Use(s.Handler)
// Route
e.Get("/stats", func(c *echo.Context) {
c.JSON(200, s.Data())
})
// Serve index file
e.Index("public/index.html")
// Serve static files
e.Static("/js", "public/js")
