Group routes

路由群組(Group routes)是一種使用相同配置或參數註冊一組路由的方法，

本文參考範例之實作如下：

package main

import (
	"net/http"

	"github.com/gin-gonic/gin"
)

func main() {
	// 初始化
	router := gin.Default()
	//建立router.Group
	v1 := router.Group("/v1")
	//建立router.Group
	v2 := router.Group("/v2")
	// Define a route for the root URL
	v1.GET("/v11", Hello_World_v1) //localhost:8080/v1/v11
	v1.GET("/v12", Hello_World_v2) //localhost:8080/v1/v12
	v2.GET("/v12", Hello_World_v2) //localhost:8080/v2/v21
	router.Run(":8080") // listen and serve on 0.0.0.0:8080 (for windows "localhost:8080")
}

func Hello_World_v1(c *gin.Context) {
	c.String(http.StatusOK, "Hello, World V1!")
}

func Hello_World_v2(c *gin.Context) {
	c.String(http.StatusOK, "Hello, World v2!")
}
