检查流是否为process.stdout [英] Check if a stream is process.stdout

问题描述

是否有一种优雅的方法来确定流是否为process.stdout

Is there an elegant way to determine if a stream is process.stdout

我正在使用流，并且希望结束流，但是发现如果流是process.stdout，则会抛出错误，因为process.stdout是

I am working with streams and will like to end the stream, but found out that if the stream is process.stdout an error is thrown because process.stdout is a special stream that cannot be closed. So want to end all streams except it's process.stdout

我尝试使用try and catch，但是process.stdout错误结束了节点进程，忽略了try and catch.

I tried using a try and catch, but the process.stdout error ends the node process, ignoring the try and catch.

推荐答案

也许这对我来说太幼稚了，但我认为您可以使用!==进行检查:

Perhaps this is naive of me, but I'd think you can just check with !==:

if (theStream !== process.stdout) {
    theStream.end();
}

流是对象，只有一个process.stdout，所以...

Streams are objects, and there's only one process.stdout, so...
