process.arch属性是流程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:
process.arch
返回值：此属性返回为其编译当前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process.arch属性的用法：
范例1：
// Node.js program to demonstrate the
// process.arch Property
// Include process module
const process = require('process');
// Printing process.arch property value
console.log(process.arch);输出：
x64
范例2：
// Node.js program to demonstrate the
// process.arch Property
// Include process module
const process = require('process');
// Printing process.arch property value
switch(process.arch) {
case 'x32':
console.log("32-bit extended systems");
break;
case 'x64':
console.log("64-bit extended systems");
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:
colsole.log(" unknown architecture");
}输出：
64-bit extended systems
注意：上面的程序将通过使用node filename.js命令。
