Illegal offset type in isset or empty

ray

PHPSocket.io服務啟動后，啟動通信就報錯
"Illegal offset type in isset or empty","file":"\socket\vendor\workerman\phpsocket.io\src\Event\Emitter.php","line":85
此報錯是概率性的，肯定是我的業(yè)務代碼出了問題，但是想知道下這個報錯會是因為什么原因引起，因為Chrome瀏覽器通信時候沒有這個報錯，業(yè)務代碼正常運行，偶爾會報此錯誤，使用火狐瀏覽器通信，就一定報此錯誤，希望可以提供一些提示信息，篩查了很久了沒有頭緒

看起來是這個$event_name 傳的值有問題，應該是個字符串，但是傳遞了數(shù)組或者對象。

用這個代碼調(diào)試試下，看下$event_name是什么值，調(diào)用棧是什么。

if (!is_scalar($event_name)) {
    var_dump($event_name);
    echo new \Exception('bad event_name)');
}

socket.io是早期為了兼容不支持websocket的瀏覽器的產(chǎn)物，現(xiàn)在基本上所有設備都支持websocket了，沒必要用socket.io了。

    前期是為了快速開發(fā)，socket.io封裝好的使用起來比較簡易，后期開發(fā)發(fā)現(xiàn)局限性確實是有的，那么是推薦直接用workerman么
  • walkor 2022-01-24

    如果是聊天類即時通訊推薦gatewayWorker
  • walkor 2022-01-24

    phpsocket.io項目后面可能就不維護了
  • ray 2022-01-24

    上邊的異常信息，您這邊能看出什么異常么
  • walkor 2022-01-24

    event_name 應該是字符串，但是傳給了一個閉包函數(shù)導致的，具體什么原因不清楚。
  • ray 2022-01-24

    這個是在emit里用了回調(diào)函數(shù)直接反饋數(shù)據(jù)了，一個前端頁面用一個這樣的長鏈接沒問題，用了兩三個之后就有這個問題了
    $socket->on('showDataInitNumber', function($msg, $ack) {

        //頂部數(shù)字跳動數(shù)據(jù)初始化 
    $data_nums = getTodayInfo($msg);
    $ack(json_encode($data_nums));
});
  • walkor 2022-01-24

    可能phpsocket.io ack這里有bug。
  • ray 2022-01-24

    我這邊主要是與Android設備以及瀏覽器做實時通信的，有那個框架比較方便開發(fā)這個而且長期維護的啊。。socket.io不維護了那我只能年后用新框架再重構一遍了
  • walkor 2022-01-24

    gatewayWorker 或者 webman/push插件 都可以
  • ray 2022-01-24

    謝謝解惑
  • ray 2022-02-14

    walkor大佬好，使用phpsocket.io主要是為了與java服務中的socket進行數(shù)據(jù)對接，也就是其中封裝好的emit方法以及emit方法中的ack回調(diào)，您推薦的gatewayWorker和webman/push插件中沒有找到對應的方法，里邊的封裝協(xié)議也沒有相關訊息，這個有什么現(xiàn)有的解決方案么
  • walkor 2022-02-14

    沒有
年代過于久遠，無法發(fā)表回答
