事件：'错误'

🌐 Event: 'error'

• <Error>

当发生错误时触发。与 net.Socket 不同，'close' 事件不会在此事件之后直接触发，除非手动调用 server.close()。请参见关于 server.listen() 的示例讨论。

🌐 Emitted when an error occurs. Unlike net.Socket, the 'close' event will not be emitted directly following this event unless server.close() is manually called. See the example in discussion of server.listen().
