rl.close()

rl.close() 方法关闭 readline.Interface 实例并放弃对 input 和 output 流的控制。 当调用时，将触发 'close' 事件。

调用 rl.close() 不会立即阻止其他由 readline.Interface 实例触发的事件（包括 'line'）。

The rl.close() method closes the readline.Interface instance and relinquishes control over the input and output streams. When called, the 'close' event will be emitted.

Calling rl.close() does not immediately stop other events (including 'line') from being emitted by the readline.Interface instance.
