Heroku上的WebSocket ERR_CONNECTION_REFUSED [英] WebSocket on Heroku ERR_CONNECTION_REFUSED

问题描述

我正在尝试使用 WebSockets 在Heroku上运行节点js应用程序。但是，我无法解决此错误（如在Chrome浏览器中看到的那样）

I am trying to run a node js app on Heroku using WebSockets. However, I am not able to resolve this error (As seen in conosle of Chrome browser)

WebSocket连接到'wss：// myappname .herokuapp.com:27225 /'失败：连接建立错误：net :: ERR_CONNECTION_REFUSED

WebSocket connection to 'wss://myappname.herokuapp.com:27225/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

自从Heroku使用'wss'在HTTPS上运行。

I am using 'wss' since Heroku runs on HTTPS.

我的客户端代码是：

$.get("https://myappname.herokuapp.com/port",function(data){
    port = data;
    console.log(data);
    host = 'wss://myappname.herokuapp.com:' + port + '/';
    ws = new WebSocket(host);
  });

我的服务器端代码是：

var WebSocketServer = require("ws").Server
var fs = require('fs');
var express = require('express'); 
var app = express();
var http = require('http');
var port = process.env.PORT || 5000;
var request = require('request');

var server = http.createServer(app);
var serverOnPort = server.listen(port);

console.log("Server listening on port ",port);

var wss = new WebSocketServer({server: serverOnPort});
console.log("websocket server created");

任何帮助将不胜感激。

Any help would be appreciated.

谢谢。

推荐答案

所以好像我在尝试用端口号覆盖它。只需将主机用作 wss：//myappname.herokuapp.com/ 效果很好。

So it seems like I was trying to over-do it with the port number. Just using the host as wss://myappname.herokuapp.com/ works well.
