Node.js process.platform 属性

process.platform 属性是进程模块的内置应用程序编程接口,用于获取操作系统平台信息。

句法:

process.platform

返回值:此属性返回一个表示操作系统平台的字符串。返回值可以是“aix”、“android”、“darwin”、“freebsd”、“linux”、“openbsd”、“sunprocess”和“win32”之一。此值在编译时设置。

下面的例子说明了在 Node.js 中process.platform 属性的使用:

示例 1:

Javascript
// Node.js program to demonstrate the
// process.platform Property
   
// Include process module
const process = require('process');
  
// Printing process.platform property value
console.log(process.platform);


Javascript
// Node.js program to demonstrate the
// process.platform Property
   
// Include process module
const process = require('process');
  
// Printing process.platform property value
var platform = process.platform;
switch(platform) {
    case 'aix': 
        console.log("IBM AIX platform");
        break;
    case 'darwin': 
        console.log("Darwin platform(MacOS, IOS etc)");
        break;
    case 'freebsd': 
        console.log("FreeBSD Platform");
        break;
    case 'linux': 
        console.log("Linux Platform");
        break;
    case 'openbsd': 
        console.log("OpenBSD platform");
        break;
    case 'sunos': 
        console.log("SunOS platform");
        break;
    case 'win32':
        console.log("windows platform");
        break;    
    default: 
        console.log("unknown platform");
}


输出:

win32

示例 2:

Javascript

// Node.js program to demonstrate the
// process.platform Property
   
// Include process module
const process = require('process');
  
// Printing process.platform property value
var platform = process.platform;
switch(platform) {
    case 'aix': 
        console.log("IBM AIX platform");
        break;
    case 'darwin': 
        console.log("Darwin platform(MacOS, IOS etc)");
        break;
    case 'freebsd': 
        console.log("FreeBSD Platform");
        break;
    case 'linux': 
        console.log("Linux Platform");
        break;
    case 'openbsd': 
        console.log("OpenBSD platform");
        break;
    case 'sunos': 
        console.log("SunOS platform");
        break;
    case 'win32':
        console.log("windows platform");
        break;    
    default: 
        console.log("unknown platform");
}

输出:

windows platform

注意:上面的程序将使用 node filename.js 命令编译和运行。
