|
|
|
||
|
|
func main() {
|
||
|
|
router := gin.Default()
|
||
|
|
router.HTMLRender = createMyRender()
|
||
|
|
router.GET("/", func(c *gin.Context) {
|
||
|
|
c.HTML(200, "index", data)
|
||

func createMyRender() multitemplate.Render {

||
|
|
r := multitemplate.New()
|
||
|
|
r.AddFromFiles("index", "base.html", "base.html")
|
