此例基于Swoole实现Websocket服务，引用依赖composer require usualtool/ut-swoole。

启动：php usualtool swoole websocket 0.0.0.0 2111
客户端JS测试：
var wsUrl = "ws://127.0.0.1:2111"; var websocket = new WebSocket(wsUrl); //onopen websocket.onopen = function(evt) { websocket.send("hello-sinwa"); console.log("conected-swoole-success"); } //onmessage websocket.onmessage = function(evt) { console.log("ws-server-return-data:" + evt.data); } //onclose websocket.onclose = function(evt) { console.log("close"); } //onerror websocket.onerror = function(evt, e) { console.log("error:" + evt.data); }
