类：net.Socket

¥Class: net.Socket

• 继承：<stream.Duplex>

  ¥Extends: <stream.Duplex>

此类是 TCP 套接字或流式 IPC 端点的抽象（在 Windows 上使用命名管道，否则使用 Unix 域套接字）。它也是 EventEmitter。

¥This class is an abstraction of a TCP socket or a streaming IPC endpoint (uses named pipes on Windows, and Unix domain sockets otherwise). It is also an EventEmitter.

net.Socket 可以由用户创建并直接用于与服务器交互。例如，它由 net.createConnection() 返回，因此用户可以使用它与服务器对话。

¥A net.Socket can be created by the user and used directly to interact with a server. For example, it is returned by net.createConnection(), so the user can use it to talk to the server.

它也可以由 Node.js 创建并在收到连接时传递给用户。例如，它被传递给 net.Server 上触发的 'connection' 事件的监听器，因此用户可以使用它与客户端进行交互。

¥It can also be created by Node.js and passed to the user when a connection is received. For example, it is passed to the listeners of a 'connection' event emitted on a net.Server, so the user can use it to interact with the client.
