Node.js stream.Writable 'pipe'事件用法及代码示例

事件：'pipe'

参数

• src <stream.Readable> 管道传输到此可写对象的源流

'pipe' 事件在可读流上调用 stream.pipe() 方法时发出，将此可写添加到其目标集。

const writer = getWritableStreamSomehow();
const reader = getReadableStreamSomehow();
writer.on('pipe', (src) => {
  console.log('Something is piping into the writer.');
  assert.equal(src, reader);
});
reader.pipe(writer);
