$connection有onWebSocketConnect方法吗?是不是搞错了

walkor

gatewayWorker 3.x才支持这个特性。你的2.0.3版本太老了。

    请问可以升级吗?如何升级?

  • walkor 2020-03-16

    从官网下载新版本gatewayWorker,替换。 替换前备份下

在这里打印拿到了,但是在Event.php 仍然拿不到

版本3.x

  • walkor 2020-05-22

    看看Events.php里是不是设置了onWebSocketConnect,把Events.php里的onWebSocketConnect删掉,2个地方都设置只会生效一个

  • dingdejing 2020-05-22

    @1:event 未设置onWebSocketConnect,gateway的onWebSocketConnect内打印 ip都看得到,但是 event onMessage 内 使用session 拿不到设置的key

  • dingdejing 2020-05-22

    重写过websocket
    为了加一个gzip压缩

    在这段代码的228-230 行处理的session,你可以自己debug下看下什么问题

  • dingdejing 2020-05-22

    好的

  • dingdejing 2020-06-07

    @1:是下了 Event下 得用 Gateway::getSession($clientId) 带能拿到,$_SESSION 拿不到

  • dingdejing 2020-06-07

    @5567:不是只有特定的某些情况 需要用 Gateway::getSession吗,

  • walkor 2020-06-08

    onMessage 和 onClose 可以拿到 $_SESSION['realIp'], 其它位置拿不到
