Question

我正在制作一个小的Heroku应用程序，该应用程序允许我通过WebSockets发送和接收数据。如标题所示，当我尝试部署该应用程序时，出现了H13错误。

这是heroku logs --tail的输出：

这是服务器端代码：

const path = require('path');
const express = require('express');
const app = express();
const https = require('https').createServer(app);
const ws = require('ws');
const server = new ws.Server({ server: https });
const port = process.env.PORT || 8080;

var htmlPath = path.join(__dirname, 'game');
app.use(express.static(htmlPath));

server.on('connection', (socket) => {
    socket.on('message', (msg) => {
        console.log('received ' + msg);
        socket.send('i can hear you!');
    });
});

https.listen(port, () => {
    console.log('listening on ' + port + ", path: " + htmlPath);
});

game目录包含多个文件和子目录，并且该目录的根目录中有一个index.html。

以前，我使用的是http节点模块而不是https，并且页面的显示效果还不错。切换到https导致应用崩溃。除了删除http和添加https之外，我没有对以前的版本进行任何更改。

我之所以切换到https的原因是，在使用net::ERR_SSL_PROTOCOL_ERROR模块时，WebSocket连接由于http而失败。

具有Express的Heroku Node.js应用-使用“ https”节点模块时，错误代码H13“连接已关闭，无响应”
