## embed 嵌入静态文件到可执行二进制文件
# 安装go-bindata

go get -u github.com/jteeuwen/go-bindata/...

# 打包静态文件

go-bindata web/...

执行次命令之后会在项目目录下生成bindata.go文件,示例命令中模板文件都在项目的web目录下

# 使用embed注册模板示例文档

示例代码：

package main

import (
"embed"
"github.com/kataras/iris/v12"
)

//go:embed embedded/*
var embeddedFS embed.FS

func main() {
app := iris.New()

tmpl := iris.HTML(embeddedFS, ".html").RootDir("embedded/templates")

tmpl.Layout("layouts/layout.html")
tmpl.AddFunc("greet", func(s string) string {
return "Greetings " + s + "!"
})

app.RegisterView(tmpl)

app.Get("/", func(ctx iris.Context) {
if err := ctx.View("page1.html"); err != nil {
ctx.HTML("<h3>%s</h3>", err.Error())
return
}
})

// remove the layout for a specific route
app.Get("/nolayout", func(ctx iris.Context) {
ctx.ViewLayout(iris.NoLayout)
if err := ctx.View("page1.html"); err != nil {
ctx.HTML("<h3>%s</h3>", err.Error())
return
}
})

// set a layout for a party, .Layout should be BEFORE any Get or other Handle party's method
my := app.Party("/my").Layout("layouts/mylayout.html")
{ // both of these will use the layouts/mylayout.html as their layout.
my.Get("/", func(ctx iris.Context) {
if err := ctx.View("page1.html"); err != nil {
ctx.HTML("<h3>%s</h3>", err.Error())
return
}
})
my.Get("/other", func(ctx iris.Context) {
if err := ctx.View("page1.html"); err != nil {
ctx.HTML("<h3>%s</h3>", err.Error())
return
}
})
}

// http://localhost:8080
// http://localhost:8080/nolayout
// http://localhost:8080/my
// http://localhost:8080/my/other
app.Listen(":8080")
