从 node.js shell 获取我的操作系统

问题描述

如何从节点外壳访问我的操作系统?

How can I access my OS from the node shell?

上下文:我正在节点中编写一个脚本，我想用默认程序打开一个文件，执行此操作的命令因操作系统而异.

Context: I'm writing a script in node that I want to open a file with the default program, and the commands for doing this vary across OS.

我已经尝试过获取操作系统的标准 javascript 方法，但它们没有奏效(出于显而易见的原因，节点中没有 navigator).

I've tried standard javascript ways of getting the OS, but they haven't worked (for obvious reasons, there is no navigator in node).

是否可以在不安装非标准模块的情况下做到这一点?

Is it possible to do this without installing nonstandard modules?

推荐答案

警告:这可能已经过时了

node.js 中没有 navigator 对象，因为它不在浏览器中运行.它在系统中运行.等价于"导航器是 process.该对象包含许多信息，例如

there is no navigator object in node.js, because it does not run in the browser. it runs in the system. "equivalent" to navigator is process. this object holds many information, e.g.

process.platform // linux

如果你想运行一个网络浏览器，你必须执行它..

if you want to run a web browser, you have to execute it..

var sys = require('sys')
// open google in default browser
// (at least in ubuntu-like systems)
sys.exec('x-www-browser google.com')

这可能不适用于较新的 node.js 版本(我有 2.x)，您可能必须使用

this might not work in newer node.js versions (i have 2.x), you might have to use

var child_process = require('child_process')
child_process.exec('x-www-browser google.com')

我想没有简单的方法可以使用其默认应用程序"在多平台上运行"任何文件，您必须了解如何在每个操作系统/桌面环境中执行此操作，并在操作系统检测后执行此操作.

i guess there is no simple way how to multiplatform "run" any file with its "default app", you would have to find out how to do it in each OS / desktop environment, and do it after OS detection.
