我想创建一个等待服务器运行的websocket客户端.如果服务器关闭连接,则应重新连接.

我尝试的不起作用,我的代码退出时出现运行时错误:

panic: runtime error: invalid memory address or nil pointer dereference

func run() {
  origin := "http://localhost:8080/"
  url := "ws://localhost:8080/ws"

  ws, err := websocket.Dial(url, "", origin)

  if err != nil {
      fmt.Println("Connection fails, is being re-connection")
      main()
  }

  if _, err := ws.Write([]byte("something")); err != nil {
    log.Fatal(err)
  }
}
