Question

我正在使用growing-file读取音频文件并将其传送到可写流，如下所示：

var GrowingFile = require('growing-file')
var audio = GrowingFile.open('test.wav')
audio.pipe(<some writable stream>);

几分钟后，我想改变流传输到的位置。

我试图创建第二个audio.pipe(<new writable stream>)但是现在只写入两个流。我将如何杀死第一个流？

Answer 1

不确定这是否是最佳解决方案，但这对我有用：

var GrowingFile = require('growing-file')
var unpipe = require('unpipe');
var audio = GrowingFile.open('test.wav')
audio.pipe(<some writable stream>);

//later in code
unpipe(audio);
audio.pipe(<some new writable stream>);

Answer 2

请参阅readable.unpipe([destination])

var GrowingFile = require('growing-file')
var audio = GrowingFile.open('test.wav')
var writeableStream = <some writable stream>
audio.pipe(writeableStream);

setTimeout(() => {
  audio.unpipe(writeableStream)
  writeableStream = <some other writable stream>
  audio.pipe(writeableStream)
}, 60000)

将文件管道到不同的流
