   private var manager:SocketManager?

        if manager != nil {

        socketHeaders["t"] = "用户token"

        config = [
            .log(true),//打印日志
            .compress,
            .extraHeaders(socketHeaders),
            .reconnects(true), //是否重连机制
            .reconnectWaitMax(7) //重新连接等待最大秒数
