process.initgroups(user, extraGroup)

• user <string> | <number> 用户名或数字标识符。

  \user <string> | <number> The user name or numeric identifier.

• extraGroup <string> | <number> 群组名或数字标识符。

  \extraGroup <string> | <number> A group name or numeric identifier.

process.initgroups() 方法读取 /etc/group 文件并使用用户所属的所有组初始化组访问列表。这是一个特权操作,要求 Node.js 进程具有 root 访问权限或 CAP_SETGID 能力。

\The process.initgroups() method reads the /etc/group file and initializes the group access list, using all groups of which the user is a member. This is a privileged operation that requires that the Node.js process either have root access or the CAP_SETGID capability.

删除权限时要小心:

\Use care when dropping privileges:

import { getgroups, initgroups, setgid } from 'node:process';
console.log(getgroups()); // [ 0 ]
initgroups('nodeuser', 1000); // switch user
console.log(getgroups()); // [ 27, 30, 46, 1000, 0 ]
setgid(1000); // drop root gid
console.log(getgroups()); // [ 27, 30, 46, 1000 ]const { getgroups, initgroups, setgid } = require('node:process');
console.log(getgroups()); // [ 0 ]
initgroups('nodeuser', 1000); // switch user
console.log(getgroups()); // [ 27, 30, 46, 1000, 0 ]
setgid(1000); // drop root gid
console.log(getgroups()); // [ 27, 30, 46, 1000 ]拷贝
