Node.js 中的 process.arch() 方法
process.arch() 方法用于获取正在进行编译的当前 node.js 进程的计算机 CPU 架构。一些可能的值包括:'arm'、'arm64'、'ia32'、'mips'、'mipsel'、'ppc'、'ppc64'、'x32'、'x64' 等。
语法
process.arch()
参数
由于会返回进行编译的代码架构,因此不需要任何输入。仅返回架构名称。
示例
创建一个名为 – architecture.js 的文件,然后复制下面的代码段。创建文件之后,使用以下命令来运行此代码,如以下示例所示 −
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);
输出
C:\home
ode>> node architecture.js x64
示例
我们来看另一个示例。
// 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."); }
输出
C:\home
ode>> node architecture.js This is a 64-bit extended systems
