heroku 连接关闭代码=H13

Question

我在heroku上部署了一个简单的nodejs服务器，带有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 Socket._handle.close (net.js:492:12)

at Socket.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，我收到了这个错误 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

这个错误在客户端

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，但问题仍然存在于正常的 REST 操作中。 现在我认为我是 SSL 问题。我用 godaddy 提供者创建了一个有效的证书，然后我成功地将它上传到 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；它们向您的应用发送纯（非 SSL）流量，因此您的应用应创建非 HTTPS 服务器。

HTTPS + SSL on Heroku - Node + Express
