静态文件

func main() {
    router := gin.Default()
    // 将指定文件夹注册到route
    router.Static("/assets", "./assets") // ./assets是文件夹目录
   //将指定文件夹中的文件注册到route
    router.StaticFS("/more_static", http.Dir("my_file_system"))
    // 将指定文件注册到route
    router.StaticFile("/favicon.ico", "./resources/favicon.ico")
    // 将指定文件注册到route
    router.GET("/local/file", func(c *gin.Context) {
        c.File("local/file.go")
    })
    // Listen and serve on 0.0.0.0:8080
    router.Run(":8080")
}
