端口34037已经在使用Heroku + Nodejs + Express + WebSockets
我试过了我能find的所有东西，但是我无法让我的部署工作。 我不断收到'应用程序错误'，虽然应用程序运行在我的http：// localserver：5000似乎问题是在bin / www
这是我在Heroku中得到的错误日志。 我想这个问题是“ 端口34037已经在使用 ”

**var express = require('express') var http = require("http"); var Crawler = require("simplecrawler"); var cheerio = require('cheerio'); var fs = require('fs'); var path = require('path'); var favicon = require('serve-favicon'); var logger = require('morgan'); var cookieParser = require('cookie-parser'); var bodyParser = require('body-parser'); var routes = require('./routes/index'); var app = express(); var port = process.env.PORT || 5000 var server = http.createServer(app) server.listen(port) console.log("http server listening on %d", port) var WebSocketServer = require('ws').Server var wss = new WebSocketServer({server: server}) console.log("websocket server created") wss.on("connection", function(ws) { fs.readFile('./playlist.json', 'utf-8', function(err, data){ if (err) throw err; ws.send(data); console.log(data); }); console.log("websocket connection open") ws.on("close", function() { console.log("websocket connection close") }) })**
和客户端：
var host = location.origin.replace(/^http/, 'ws') var ws = new WebSocket(host); ws.onmessage = function (event) { playthelistclient.push(event.data); };
我关于端口的bin / www文件部分：
var port = normalizePort(process.env.PORT || '3000'); app.set('port', port);
希望你们能帮忙。
在www文件中注释掉与端口有关的东西，因为你的app.js文件中已经有了这些东西：
//var port = normalizePort(process.env.PORT || '3000'); //app.set('port', port); //server.listen(port);
