Gin加载history模式下打包后的Vue文件，刷新找不到页面404

import (
    "io/ioutil"

    "github.com/gin-contrib/static"
    "github.com/gin-gonic/gin"
)
app := gin.Default()
//加载静态资源
app.Use(static.Serve("/", static.LocalFile("dist", true)))
app.NoRoute(func(c *gin.Context) {
    accept := c.Request.Header.Get("Accept")
    flag := strings.Contains(accept, "text/html")
    if flag {
        content, err := ioutil.ReadFile("dist/index.html")
        if (err) != nil {
            c.Writer.WriteHeader(404)
            c.Writer.WriteString("Not Found")
            return
        }
        c.Writer.WriteHeader(200)
        c.Writer.Header().Add("Accept", "text/html")
        c.Writer.Write((content))
        c.Writer.Flush()
    }
})

亲自测试，可以实现。
