我们使用WebSocket的时候,是通过new一个WebSocket对象,所以Websocket是一个类,同时在创建对象的时候,需要传递一些配置对象作为参数。由于WebSocket可以复用http握手通道,所以我们需要有一个web服务器,才能复用http的握手通道,所以如果我们已经创建好了一个web服务器,那么我们可以把这个web服务器传递给WebSocket,那么WebSocket就...
let socket = new WebSocket('ws://127.0.0.1:8081'); socket.binaryType = 'arraybuffer'; // Wait until socket is open socket.addEventListener('open', function (event) { // Send binary data const typedArray = new Uint8Array(4); socket.send(typedArray.buffer); }); // Receive binary data ...

if (ws.readyState === WebSocket.OPEN) { // 发,送 ws.send(JSON.stringify(guestInfo)); // 用随机来“装”得更像不定时推送一些 setTimeout(function() { sendGuestInfo(ws); }, (Math.random() * 5 + 3) * 1000); } } });
WebSocket可以通过ArrayBuffer,发送或接收二进制数据。 let socket = new WebSocket('ws://127.0.0.1:8081'); socket.binaryType = 'arraybuffer'; // Wait until socket is open socket.addEventListener('open', function (event) { // Send binary data ...
最近在工作中遇到了需要服务器推送消息的场景,这里总结一下收集整理WebSocket相关资料的收获。 1. 概述 1.1 服务器推送 WebSocket作为一种通信协议,属于服务器推送技术的一种,IE10+支持。 服务器推送技术不止一种,有短轮询、长轮询、WebSocket、Server-sent Events(SSE)等,他们各有优缺点: ...

关闭WebSocket连接,会触发close事件。connection.onclose = wsClose;function wsClose () { console.log(“Closed”);} connection.close();发送数据和接收数据 连接建⽴后,客户端通过send⽅法向服务器端发送数据。connection.send(message);除了发送字符串,也可以使⽤ Blob 或 ArrayBuffer 对象发送⼆进制数据...
