刚安装了ws，试着库中的例子发现连接不了，也不报错，有没有人遇到过这个问题，怎么解决的 浏览器为chrome var WebSocketServer = require(’…/node_modules/ws’).Server , http = require(‘http’) , express = require(‘express’) , //app = express.createServer(); app = express();
app.use(express.static(__dirname + ‘/public’)); app.listen(8080);
var wss = new WebSocketServer({server: app}); wss.on(‘connection’, function(ws) { var id = setInterval(function() { ws.send(JSON.stringify(process.memoryUsage()), function() { /* ignore errors */ }); }, 100); console.log(‘started client interval’); ws.on(‘close’, function() { console.log(‘stopping client interval’); clearInterval(id); }); });
