Node.js process.arch()用法及代碼示例

process.arch() 方法用於獲取正在編譯當前 node.js 進程的計算機的 CPU 架構。一些可能的值是：'arm', 'arm64', 'ia32', 'mips', 'mipsel', 'ppc', 'ppc64', 'x32', 'x64'， 等等。

用法

process.arch()

參數

因為它返回正在編譯的代碼的體係結構。它不需要任何輸入。它隻返回架構名稱。

示例

創建一個名為 architecture.js 的文件並複製以下代碼片段。創建文件後，使用以下命令運行此代碼，如下例所示 -

node architecture.js

architecture.js

// Node.js program to demonstrate the use of process.arch

// Importing the process module
const process = require('process');

// Printing the arch of given system
console.log(process.arch);

輸出

C:\home\node>> node architecture.js
x64

示例

讓我們再看一個例子。

// Node.js program to demonstrate the use of process.arch

// Importing the process module
const process = require('process');

// Printing the value for given architecture
switch(process.arch) {
   case 'x32':
      console.log("This is a 32-bit extended systems");
      break;
   case 'x64':
      console.log("This is a 64-bit extended systems");
      break;
   case 'arm':
      console.log("This is a 32-bit Advanced RISC Machine");
      break;
   case 'arm64':
      console.log("This is a 64-bit Advanced RISC Machine");
      break;
   case 'mips':
      console.log("This is a 32-bit Microprocessor without " + "Interlocked Pipelined Stages");
      break;
   case 'ia32':
      console.log("This is a 32-bit Intel Architecture");
      break;
   case 'ppc':
      console.log("This is a PowerPC Architecture.");
      break;
   case 'ppc64':
      console.log("This is a 64-bit PowerPC Architecture.");
      break;
   // You can add more architectures if you know...
   default:
      colsole.log("This architecture is unknown.");
}

輸出

C:\home\node>> node architecture.js
This is a 64-bit extended systems
