视频综合管理平台EasyNVS在实现代理时调用EasyDSS接口如何携带token？

if frpc.Token == "" || time.Since(frpc.TokenTime).Seconds() > float64(conf2.GetConf().SysTokenTimeout) {
   if err := frpc.RefreshToken(); err != nil {
      log.Println(err)
   }
}
httpPort := utils.Conf().Section("http").Key("http_port").MustInt(10080)
director := func(req *http.Request) {
   req.URL.Scheme = "http"
   req.URL.Host = fmt.Sprintf("127.0.0.1:%d", httpPort)
   req.URL.Path = "/live/list"
 
   req.Header.Del("Cookie")
   req.AddCookie(&http.Cookie{
      Name:  consts.SessionSID,
      Value: frpc.Token,
   })
}
