Node.js Heroku应用程序上的TCP连接 [英] TCP connection on Node.js Heroku app
本文介绍了Node.js Heroku应用程序上的TCP连接的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个简单的TCP聊天应用程序，使用Node.js在本地运行。我想将这部署到Heroku。我对Heroku和Node.js都很陌生，并且立即遇到了无法远程登录到任何特定端口以访问此聊天客户端的问题。理想的情况下（用forman开始在本地工作）是我将telnet到服务器并开始发布可以通过Heroku的终端日志读取的数据。如果应用程序在本地运行，则可以使用telnet http://tcp-chat.herokuapp.com 进行连接5000通过领班启动或telnet启动时 http://tcp-chat.herokuapp.com 3000启动时通过节点index.js。在Heroku上，我无法使用任何这些端口进行连接。我见过的Heroku的每个例子都使用Express，我不想将它用于学习目的。任何人都可以解释，如果这可以纠正，为什么会发生这种情况？
I've got a simple TCP chat application below running locally using Node.js. I would like to deploy this to Heroku. I'm quite new to both Heroku and Node.js and instantly ran into issues where I could not telnet into any specific port to access this chat client. The ideal situation (which works locally with forman start) is that I would telnet into the server and start posting data that can be read out via the terminal logs for Heroku. If the app is running locally, I can connect using telnet http://tcp-chat.herokuapp.com 5000 when starting via foreman start or telnet http://tcp-chat.herokuapp.com 3000 when starting via node index.js. On Heroku, I am unable to connect using any of these ports. Every example I've seen for Heroku uses Express, which I don't want to use for my learning purposes. Would anyone be able to explain if this can be corrected and why this is happening?
index.js
index.js
var net = require('net');
//Keep track of connections
var count = 0;
var server = net.createServer(function (connection) {
connection.setEncoding('utf8');
connection.write(
'\n > welcome to \033[92mnode-chat\033[39m!' +
'\n > ' +count+ ' other people are connected at this time.' +
'\n > please write your name and press enter: '
);
count++;
connection.on('data', function (data) {
console.log(data);
});
connection.on('close', function (error) {
console.log('Error: ' + error);
count--;
});
});
var port = process.env.PORT || 3000;
server.listen(port, function () {
console.log('\033[90m server listening on *:' + port + '\033[39m');
});

推荐答案
Heroku仅允许HTTP流量传入您的服务器。你需要找到一个不同的主机。
Heroku only allows HTTP traffic incoming to your server. You'll need to find a different host.
