推荐答案

它的工作方式客户端和服务器都有一个IP地址。如果两者都在同一台机器上运行，它可能会是相同的。 服务由端口号定义。 HTTP为80，SMTP为21等。



您必须同时进行TCP通信，而且 - 您使用端口8080（这是一种常见的选择）对于HTTP代理）。



这就是你所拥有的，IPAddress - 谁，端口 - 做什么。如果这些信息不够，那么你必须在TCP堆栈上面自己的角色。

The way it works is both client and server have an IP address. If both run on the same machine it will likely be the same. The 'service' is defined by the port number. 80 for HTTP, 21 for SMTP etc.

You have to have both for TCP communication, and you do - you're using port 8080 (which is a common choice for an HTTP proxy).

That's all you have, IPAddress - Who, Port - Doing What. If that information is not enough then you'll have to role your own above the TCP stack.
