你需要检查在尝试发送数据之前,连接是否已经处于OPEN状态。 检查WebSocket的初始化及连接代码: 确保你的WebSocket连接代码正确无误。以下是一个基本的WebSocket连接示例: javascript const socket = new WebSocket('wss://example.com/socketserver'); socket.onopen = function(event) { console.log('Connection ...
Some protocols do not keep the connection open. And if they open again they assume to have a clean session. But because the c8ylp does not disconnect the websocket, the tcp connection on the device side remains open. Therefore the c8ylp ...

WebSocket is closed before the connection is established 最近socket.io是挺流行的,幼麟棋牌和一些好的开源项目也使用这个框架,在搭建其平台示例的出现这个错误,网上找了半天竟然没有找到解决办法,开始以为是版本socket.io版本问题,换了2.0一样,用telnet连接端口正常,但是客户端怎么都连接不上。
WebSocket 对象提供了用于创建和管理 WebSocket 连接，以及可以通过该连接发送和接收数据的 API。
