Question

我正在使用express-ws创建一个支持websocket的express.js路由。

这是我的express.js主文件：

const express = require('express');
let expressWs = require('express-ws');
expressWs = expressWs(express());
const app = expressWs.app;
const router = express.Router();

...

const playerRouter = require('./routes/player')(router);

...

module.exports = app;

这是我的路线模块：

module.exports = (router, db) => {
  router.get('/api/player/:id', (req, res, next) => {
    res.send('hello from player route');
    res.end();
  });

  router.ws('/api/player/:id', (ws, req) => {
    ws.on('message', msg => {
      console.log('msg', msg);
    });
  });
}

Localhost：我能够使用websocket调试工具连接到此路由，并且我能够向/ console.log发送消息。

Heroku：我可以通过浏览器浏览到这条路线（成功返回“来自玩家路线的hello”），但是当我尝试使用websocket调试工具进行连接时，我收到以下服务器错误：

heroku [router]：at = error code = H13 desc =“Connection without closed without”method = GET path =“/ api / player / 1”host = shielded-river-25076.herokuapp.com request_id = 1ea0d954- 7b06-4f46-b86f-6016cb910be4fwd =“2.229.13.61”dyno = web.1 connect = 0ms service = 1ms status = 503 bytes = 0 protocol = http

express-ws route无法连接到heroku
