echo的路由

package main

import (
	"fmt"
	"net/http"
	"strings"

	"github.com/labstack/echo"
)

type M map[string]interface{}

func main() {
	r := echo.New()

	r.GET("/", func(ctx echo.Context) error {
		data := "Hello from /index"
		return ctx.String(http.StatusOK, data)
	})

	r.GET("/html", func(ctx echo.Context) error {
		data := "Hello from /html"
		return ctx.HTML(http.StatusOK, data)
	})

	r.GET("/index", func(ctx echo.Context) error {
		return ctx.Redirect(http.StatusTemporaryRedirect, "/")
	})

	r.GET("/json", func(ctx echo.Context) error {
		data := M{"Message": "Hello", "Counter": 2}
		return ctx.JSON(http.StatusOK, data)
	})

	// http://localhost:9000/page1?name=jayce
	r.GET("/page1", func(ctx echo.Context) error {
		name := ctx.QueryParam("name")
