heroku 连接关闭代码=H13

我在heroku上部署一个简单的nodejs服务器，并使用ssl有效证书

var https = require('https');
var express = require('express');
var bodyParser = require('body-parser');
var fs = require('fs');

var app = express();
var cors = require('cors');

var credentials = {
    key: fs.readFileSync('./cert/key.key'),
    cert: fs.readFileSync('./cert/cert.crt'),
    ca: fs.readFileSync('./cert/bundle.crt'),
    requestCert: true,
    rejectUnauthorized: false
};

var server = https.createServer(credentials, app);

var io = require('socket.io')(server);

app.use(cors()); 
app.use(bodyParser.json({limit: '12mb'})); 
app.use(bodyParser.urlencoded({limit: '12mb', extended: true }));

io.on('connection', function(socket){
   console.log(socket);
   socket.on('authenticate', function(data){

      console.log(data);
   });
});

var port = process.env.PORT || 8080;

server.listen(port, function () {
    console.log("server listen on", this.address());
});

server.on('clientError', function(err) {
    console.log('ERROR', err);
});

问题是当我启动应用程序时收到此错误

ERROR { Error: socket hang up
at TLSSocket.<anonymous> (_tls_wrap.js:820:25)
at emitOne (events.js:101:20)
at TLSSocket.emit (events.js:188:7)

at TCP._handle.close [as _onclose] (net.js:492:12) code: 'ECONNRESET' }

当我尝试通过 chrome 连接到我的服务器时，我收到此错误 在服务器端

2017-01-05T15:03:43.465542+00:00 heroku[router]: at=error code=H13 desc="Connection closed without response" method=GET path="/socket.io/?EIO=3&transport=polling&t=LblA3JZ" host=www.myapp.com request_id=51982ce9-99e3-4677-acb4-a0f14eb88999 fwd="95.251.90.218" dyno=web.1 connect=1ms service=2ms status=503 bytes=0

以及客户端的这个错误

XMLHttpRequest cannot load https://www.myapp.com/socket.io/?EIO=3&transport=polling&t=LblDK25. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://192.168.0.8:8100' is therefore not allowed access. The response had HTTP status code 503.

一开始我以为是 socket.io，但正常 REST 操作时问题仍然存在。 现在我认为我有 SSL 问题。我与 godaddy 提供商创建了一个有效的证书，并成功将其上传到 heroku。事实上，如果我尝试通过 https 连接连接到我的应用程序，则证书是有效的。也许问题是当我尝试将此证书上传到我的 Nodejs 应用程序时。有人可以帮助我吗？提前致谢

您应该使用 HTTP 服务器而不是 HTTPS。 SSL 终止发生在 Heroku 的负载均衡器上；它们向您的应用程序发送普通（非 SSL）流量，因此您的应用程序应该创建一个非 HTTPS 服务器。

Heroku 上的 HTTPS + SSL - Node + Express
