process.argv

• 类型: <string[]>

process.argv 属性返回一个数组，包含在启动 Node.js 进程时传入的命令行参数。第一个元素将是 process.execPath。如果需要访问 argv[0] 的原始值，请参阅 process.argv0。第二个元素将是正在执行的 JavaScript 文件的路径。其余的元素将是任何额外的命令行参数。

【The process.argv property returns an array containing the command-line arguments passed when the Node.js process was launched. The first element will be process.execPath. See process.argv0 if access to the original value of argv[0] is needed. The second element will be the path to the JavaScript file being executed. The remaining elements will be any additional command-line arguments.】

例如，假设 process-args.js 的以下脚本：

【For example, assuming the following script for process-args.js:】

import { argv } from 'node:process';

// print process.argv
argv.forEach((val, index) => {
  console.log(`${index}: ${val}`);
});const { argv } = require('node:process');

// print process.argv
argv.forEach((val, index) => {
  console.log(`${index}: ${val}`);
});拷贝

以如下方式启动 Node.js 进程：

【Launching the Node.js process as:】

node process-args.js one two=three four 拷贝

将生成输出：

【Would generate the output:】

0: /usr/local/bin/node
1: /Users/mjr/work/node/process-args.js
2: one
3: two=three
4: four 拷贝
