我正在使用socket.io来处理当前正在制作的应用(在heroku上)并且我一直收到这些错误。似乎所有东西仍然可以正常工作,但我的日志充满了错误。

正如您所看到的,有2个heroku应用同时报告错误,这是因为' fixtrackapp'将socket.io请求代理到我的api服务器(' fixtrackapi')。
客户代码:
const socket = io('', { path: '/ws' });
这是代理代码:
const proxy = httpProxy.createProxyServer({
target: targetUrl,
changeOrigin: true,
ws: true
});
app.use('/api', (req, res) => {
proxy.web(req, res, {target: targetUrl + '/v1'});
});
app.use('/ws', (req, res) => {
proxy.web(req, res, {target: targetUrl + '/ws'});
});
Api服务器代码:
const app = express();
const server = new http.Server(app);
const io = socketio(server);
io.path('/ws');
const runnable = app.listen(port, () => console.log(`API running on port ${port}`));
io.listen(runnable);
我还尝试过使用setinterval在客户端上运行我自己的活着,然后发送了一个' ping'每8秒一次。但我仍然有错误(虽然有时看起来我的错误很少)。
知道可能导致这种情况的原因是什么?
