go使用embed渲染前端静态项目

package main

import (
	"embed"
	"fmt"
	"github.com/gin-gonic/gin"
	"io/fs"
	"net/http"
)

// 嵌入static文件夹下dist的所有文件
//
//go:embed static/dist
var f embed.FS

func main() {
	r := gin.Default()
	st, _ := fs.Sub(f, "static/dist")
	r.StaticFS("/", http.FS(st))
	r.NoRoute(func(c *gin.Context) {
		data, err := f.ReadFile("static/dist/index.html")
		if err != nil {
			c.AbortWithError(http.StatusInternalServerError, err)
			return
		}
		c.Data(http.StatusOK, "text/html; charset=utf-8", data)
	})

	err := r.Run("0.0.0.0:5999")
	if err != nil {
		fmt.Println(err)
	}
}
