└─embed_ui.go
└─dist
└─index.html
└─static
├─css
└─ ...
├─fonts
└─ ...
└─js

└─main.go
└─go.mod
//embed_ui.go
package ui
import (
`embed`
)
//go:embed dist
var WebUI embed.FS
//main.go
// 嵌入普通静态资源
type StaticResource struct {
// 静态资源
staticFS embed.FS
// 设置embed文件到静态资源的相对路径，也就是embed注释里的路径
path string
}
// 静态资源被访问逻辑
func (_this_ *StaticResource) Open(name string) (fs.File, error) {
var fullName string
if strings.Contains(name,`/`){
fullName = path.Join(_this_.path,"static",name)
}else{
fullName = path.Join(_this_.path,name)
}
file, err := _this_.staticFS.Open(fullName)
return file, err
}
func main() {
// 设置静态资源
static := &StaticResource{
staticFS: ui.WebUI,
path: "dist",
}
engine := gin.Default()
{
// 设置
engine.StaticFS("/static/",http.FS(static))
// 首页
engine.GET("/", func(context *gin.Context) {

context.Writer.Write(indexHTML)
context.Writer.Header().Add("Accept","text/html")
context.Writer.Flush()
})

engine.Run()
