事件:'line'


【Event: 'line'

'line' 事件会在 input 流接收到换行输入(\n\r\r\n)时触发。这通常发生在用户按下 回车Return键时。

如果从流中读取了新数据,并且该流在没有最终换行符的情况下结束,则也会触发 'line' 事件。

【The 'line' event is also emitted if new data has been read from a stream and that stream ends without a final end-of-line marker.】

监听函数会被调用,并传入一个包含收到的单行输入的字符串。

【The listener function is called with a string containing the single line of received input.】

rl.on('line', (input) => {
  console.log(`Received: ${input}`);
});
