Question

我使用 Node.JS 创建（我复制了）聊天服务器，服务器位于我的LocalHost： 127.0.0.1 ，仅我可以使用聊天，但我希望任何人都可以使用服务器，所以我想知道如何将这个聊天服务器放在我的真实服务器中： http://sistema.agrosys.com.br/sistema/padrao/HTML5/WebSocket/ 的
并且：http://calnetaskmanager.herokuapp.com/

但我现在不知道如何将chat-server.js放入我的 Heroku 服务器。

我该怎么做才能实现。

提前致谢

如果您想了解会发生什么：client side on my server

    var myColor = false;
    // my name sent to the server
    var myName = false;

    // if user is running mozilla then use it's built-in WebSocket
    window.WebSocket = window.WebSocket || window.MozWebSocket;

    // if browser doesn't support WebSocket, just show some notification and exit
    if (!window.WebSocket) {
        content.html($('<p>', {
            text: 'Sorry, but your browser doesn\'t ' + 'support WebSockets.'
        }));

Answer 1

您需要在某个地方托管Node.js代码，例如在Heroku，他们有免费的Node.js计划，然后您将获得一个公共网址，您可以将其分发到其他

Answer 2

让每个人都可以使用......这很容易。

将代码部署到公共主机上 - 比如Heroku @dark_ruby在他的回答中提到。
为计算设备提供浏览器（nexus 7会做）全世界的每个人
将其配置为将您的服务作为默认主页

完成。

如何让每个人都可以访问我的服务器？
