    // json
	r.GET("/someJSON", func(c *gin.Context) {

	})    
    
    // 重定向
    r.GET("/test", func(c *gin.Context) {
        c.Redirect(http.StatusMovedPermanently, "http://www.google.com/")
    })    

	// By default it serves on :8080 unless a
	// PORT environment variable was defined.
	router.Run()
	// router.Run(":3000") for a hard coded port
}

build

go
go build main.go
// 上面的命令将构建一个可执行的二进制文件 main ，你可以使用 $ ./main 命令来运行构建号的应用。 哇，我们的 todo 应用现在运行在了本地的 8080 端口了。 它将在终端显示调试日志，因为 gin 默认以 debug 模式运行在 8080 端口。
