node.js 的 os 模块

 

　　Node.js的os module 提供了一系列跟操作系统相关的操作函数，比较简单，所以功能也就十分有限。我们可以去官网看各个函数的介绍：

　　http://nodejs.org/api/os.html 

 2 var os = require('os');  3 

 4 console.log('the os tmpdir is: ' + os.tmpdir());  5 console.log('the endianness of this os is: ' + os.endianness());  6 console.log('the hostname of this os is: ' + os.hostname());  7 console.log('the type of this os is: ' + os.type());  8 console.log('the platform of this os is: ' + os.platform());  9 console.log('the arch of this os is: ' + os.arch()); 10 console.log('the release of the os is: ' + os.release()); 11 console.log('the uptime os the os is: ' + os.uptime()); 12 

13 

14 console.log('the end of line of this os is: ' + os.EOL); //os.EOL：操作系统的换行符 15 console.log('................................................'); 16 console.log('................................................'); 17 showObj(os.cpus()); 18 console.log('................................................'); 19 console.log('................................................'); 20 showObj(os.networkInterfaces()); 21 console.log('................................................'); 22 console.log('................................................'); 23 showObj(os.loadavg()); 24

28 function showObj(obj){ 29     if (obj == null) { 30         console.log('error: ' + obj); 31         return false; 32  } 33     for (var key in obj) { 34         //key is a string, so we cannot use obj.key to replace obj[key] at here. For example, if name is a property of obj:
　　　　　　//(obj.name is right, but obj."name" is wrong.)
　　　　　　//(obj["name"] is right, but obj[name] is wrong.)


35         if (typeof(obj[key]) == 'array' || typeof(obj[key]) == 'object') { 36  showObj(obj[key]); 37         } else { 38             if (obj[key] != null) 39                 console.log(key + "=" + obj[key]); 40  } 41  } 42 } 43
