readable.resume()


readable.resume() 方法会使显式暂停的 Readable 流恢复触发 'data' 事件,将流切换到流动模式。

【The readable.resume() method causes an explicitly paused Readable stream to resume emitting 'data' events, switching the stream into flowing mode.】

readable.resume() 方法可以用来完全读取流中的数据,而无需实际处理这些数据:

【The readable.resume() method can be used to fully consume the data from a stream without actually processing any of that data:】

getReadableStreamSomehow()
  .resume()
  .on('end', () => {
    console.log('Reached the end, but did not read anything.');
  }); 

如果存在 'readable' 事件监听器,readable.resume() 方法将不起作用。

【The readable.resume() method has no effect if there is a 'readable' event listener.】
