os.arch()方法是os模块的内置应用程序编程接口,用于获取编译当前node.js的计算机的CPU体系结构。
用法:
os.arch()
参数:此方法不接受任何参数。
返回值:此方法返回为其编译当前node.js的操作系统CPU体系结构。可能的值为“ x32”,“ x64”,“ arm”,“ arm64”,“ s390”,“ s390x”,“ mipsel”,“ ia32”,“ mips”,“ ppc”和“ ppc64”。
以下示例说明了Node.js中os.arch()方法的使用:
范例1:
// Node.js program to demonstrate the    
// os.arch() method 
  
// Allocating os module 
const os = require('os'); 
  
// Printing os.arch() 
console.log(os.arch());输出:
x64
范例2:
<script> 
// Node.js program to demonstrate the    
// os.arch() method 
   
// Allocating os module 
const os = require('os'); 
   
// Printing os.arch() description 
// of the architecture 
switch(os.arch()){ 
    case 'x32':
        console.log("32-bit extended system"); 
        break; 
       
    case 'x64':
        console.log("64-bit extended system"); 
        break; 
   
    case 'arm':
        console.log("32-bit  Advanced RISC Machine"); 
        break; 
   
    case 'arm64':
        console.log("64-bit  Advanced RISC Machine"); 
        break; 
   
    case 's390':
        console.log("31-bit The IBM System/390, the"
                + " third generation of the System/360"
                + " instruction set architecture"); 
        break; 
   
    case 's390x':
        console.log("64-bit The IBM System/390, the"
                + " third generation of the System/360"
                + " instruction set architecture"); 
        break; 
   
    case 'mipsel':
        console.log("64-bit Microprocessor without"
                + " Interlocked Pipelined Stages"); 
        break; 
   
    case 'mips':
        console.log("32-bit Microprocessor without"
                + " Interlocked Pipelined Stages"); 
        break; 
   
    case 'ia32':
        console.log("32-bit Intel Architecture"); 
        break; 
   
    case 'ppc':
        console.log("PowerPC Architecture."); 
        break; 
   
    case 'ppc64':
        console.log("64-bit PowerPC Architecture."); 
        break; 
   
    default:
        console.log(" unknown processor"); 
} 
</script>输出:
64-bit extended system
注意:上面的程序将通过使用node index.js命令。
