Question

我有以下代码片段，我需要扩展它来定义多个WebSockets，我对如何解决这个问题一无所知：

    var registerWebSocketHandlers = function(webSocket) {
    webSocket.onclose = function(){
        setTimeout(service.reopen, reconnectTimeout *= 2);
    };

    webSocket.onopen = function(e) {
        icc.publish('webSocket.reconnect');
        reconnectTimeout = defaultReconnectTimeout; //reset this
        deferredSend();
    };

    webSocket.onerror = function(e) {
        throw new Error("[WebSocket] An error occured " + e);
    };
    }

    var openConnection = function() {
    connectionWasOpenBefore = true;
    webSocket = new $window.WebSocket(xyz);
    webSocket.id = uniqid();
    registerWebSocketHandlers(webSocket);
    };

    var uniqid = function() {
    return (new Date().getTime()).toString(16);
    }

    service.setMessageEventHandler = function(cb) {
    webSocket.onmessage = function(msg) {
        if(msg.data.indexOf('Status: connected') === 0)
        {
            return;
        }
        var jsonObj = JSON.parse(msg.data);
        cb(jsonObj);
    };
};

如何扭曲代码以满足多个WebSockets的需要并为其附加适当的回调？

使用多重模式。

var firstWebSocket = SocketFactory.getInstance('firstSocket');
// It would probably be a good idea to add this listener in the SocketFactory instead and broadcast an event when there's a message so multiple listeners can respond to it.
firstWebSocket.onmessage = function(){...};
var secondWebSocket = SocketFactory.getInstance('secondSocket');
secondWebSocket.onmessage = function(){...};

这将按名称分隔您的不同websockets。使用getInstance（＆＃39;无论如何＆＃39;）来获得标记为＆＃39;的任何＆＃39;。

if (isset($_GET['search'])) {
    if (strpos($_SERVER['REQUEST_URI'], '?') !== false) {
       header('Location: http://'.$_SERVER['HTTP_HOST'].'/offstreams/search/'.urlencode($_GET['search']));
       exit();
    }
    echo $_GET['search'];   
}

接下来，您可以从任何其他区域按实例名称访问配置的websockets。

如何在JavaScript中定义和接收来自多个WebSockets的数据？
