什么是注册表设置不正确？

我正在构建我的第一个Go Web项目，并且在加载页面时在浏览器控制台上收到此错误

Refused to apply style from 'http://localhost:8080/static/css/processor-auth.css' because its MIME type ('text/plain') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

我不确定自己在做什么错，因为我已经添加了此代码来加载静态文件

http.Handle("/static/",http.StripPrefix("/static/",http.FileServer(http.Dir("static"))))

这是我的main.go文件的样子：

 package main

import(
    "net/http"
    "os"
    "html/template"

    "github.com/julienschmidt/httprouter"
)


// Auth struct handler
type auth struct{}

func (auth *auth) ServeHTTP(w http.ResponseWriter, r *http.Request){
    wd,_:= os.Getwd()
    t := template.Must(template.ParseFiles(wd+"/templates/processor/auth.html"))
    err:=t.Execute(w,nil)

    if err !=nil{
        http.Error(w,"Could not execute template",500)
    }

}


func main(){

    router:= httprouter.New()
    // set the static files
    http.Handle("/static/",http.StripPrefix("/static/",http.FileServer(http.Dir("static"))))

    router.Handler("GET","/auth",&auth{})

    server := http.Server{
        Addr:"127.0.0.1:8080",
        Handler:router,
    }

    server.ListenAndServe()
}

httprouter

http.Handle("/static/",http.StripPrefix("/static/",http.FileServer(http.Dir("static"))))

router.ServeFiles("/static/*filepath",http.Dir("static"))
