代码笔记

[GIN-debug] [WARNING] Since SetHTMLTemplate() is NOT thread-safe. It should only be called
at initialization. ie. before any route is registered or the router is listening in a socket:

        router := gin.Default()
        router.SetHTMLTemplate(template) // << good place

Gin和Echo有点不一样，需要在注册路由之前注册模板

注册子目录的html文件
