像Yahoo Messenger一样写Messenger [英] Writing Messenger Like Yahoo Messenger

问题描述

大家好
我要写像Yahoo Messenger那样的信使，该信使可以在Internet上工作.
因此，我在最近的几个月中学习了套接字编程.
我编写了两种程序(C#.net 2010中的Windows应用程序)
1.客户端版本:在特定端口上发送和接收数据.
2.Server版本:侦听此端口并回答来自客户端版本的数据并将数据路由到另一个客户端.(例如yahoo Messenger)
但是这些程序可以在LAN网络中使用.

对于其他程序，我的程序具有用于对话日志和...的数据库.

我问题的重要部分是:
我如何更改程序以在Internet连接上工作?

非常感谢.

推荐答案

不需要更改，除了IP地址(无论如何，您都不应对其进行硬编码).您的服务部件及其IP地址和端口，应该对Internet可见，仅此而已.例如，如果您正在使用防火墙，则应将其配置为允许使用您的协议或端口进行通信.这些细节与您的代码本身无关.

No change is needed, except, perhaps, IP addresses (which you should never hard-code, anyway). Your service part, with its IP address and port, should be visible to Internet, that''s it. For example, if you have firewalls on the way, they should be configured to allow the traffic with your protocol or port. Those are detail not related to your code itself.
