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 
25 
26 
27 
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
