如何测试使用JavaScript开发的WebSocket
我创建了WebSocket.js，但遗憾的是由于数据不可用，我无法测试它。 要求是来自各种来源的数据，所以我有多个sockets。 注意：我想特别测试我的socket.onMessage表现为不同的套接字。 请在下面找到代码段：
var webSocket; var txQueue = []; var defaultReconnectTimeout = 1000; //will be multiplied by 2 and saved into reconnectTimeout on each try var reconnectTimeout = defaultReconnectTimeout; var registerWebSocketHandlers = function(webSocket) { webSocket.onclose = function(){ setTimeout(service.reopen, reconnectTimeout *= 2); }; webSocket.onopen = function(e) { reconnectTimeout = defaultReconnectTimeout; //reset this deferredSend(); }; webSocket.onerror = function(e) { throw new Error("[WebSocket] An error occured " + e); }; } var uniqid = function() { return (new Date().getTime()).toString(16); } var deferredSend = function() { if(!service.isOpen()) { $timeout(deferredSend, 100); return; } while(txQueue.length && service.isOpen()) { var payload = txQueue.shift(); webSocket.send(typeof payload === 'string' ? payload : JSON.stringify(payload)); } }; var createNewWebSocketInstance = function(apiUrl){ var websocket = new $window.WebSocket(apiUrl); websocket.id = uniqid(); return websocket; } // TODO: this is a bit hacky since we directly bind it to the raw window event $window.onbeforeunload = function(e) { service.close(); }; var service = {}; service.setMessageEventHandler = function(name,cb) { instances[name].onmessage = function(msg) { if(msg.data.indexOf('Status: connected') === 0) { return; } var jsonObj = JSON.parse(msg.data); cb(jsonObj); }; }; service.isOpen = function() { return webSocket.readyState === 1; }; service.send = function(msg) { txQueue.push(msg); deferredSend(); }; service.close = function() { return webSocket.close(); }; service.reopen = function() { // get old message handler var msgHandler = webSocket.onmessage; // try closing the previous WebSocket service.close(); // open new WebSocket openConnection(); // re-attach old handler to new WebSocket webSocket.onmessage = msgHandler; }; service.getId = function() { return webSocket.id; } // Returns an already existing instance of the socket, if unavailable then creates a new one. service.getInstance = function(name, config) { if(!(name in instances)) { instances[name] = createNewWebSocketInstance(config); } registerWebSocketHandlers(instances[name]); return instances[name]; }; return service; 您可以在websocket.org上使用websocket.html测试WebSocket 。 回声测试创建您自己的测试
使用文本编辑器，复制以下代码并将其保存为硬盘驱动器上的某些websocket.html 。 然后只需在浏览器中打开它。 该页面将自动连接，发送消息，显示响应并关闭连接。
