node . js process . arch Property
原文:https://www . geesforgeks . org/node-js-process-arch-property/
process.arch 属性是进程模块的内置应用编程接口，用于获取当前节点. js 所编译的计算机的 CPU 架构。
语法:
process.arch
返回值:该属性返回为其编译当前 node.js 的操作系统 CPU 架构。可能的值为“x32”、“x64”、“arm”、“arm64”、“s390”、“s390x”、“mipsel”、“ia32”、“mips”、“ppc”和“ppc64”。
下面的例子说明了进程的使用。
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
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:以上程序使用node filename.js命令编译运行。
