process.seteuid(id)


process.seteuid() 方法为进程设置有效的用户标识。(参见 seteuid(2))。 id 可以传入数字 ID 或用户名字符串。 如果指定了用户名,则此方法在解析关联的数字 ID 时会阻塞。

if (process.geteuid && process.seteuid) {
  console.log(`当前的 uid: ${process.geteuid()}`);
  try {
    process.seteuid(501);
    console.log(`新的 uid: ${process.geteuid()}`);
  } catch (err) {
    console.log(`无法设置 uid: ${err}`);
  }
}

这个函数只在 POSIX 平台有效(在 Windows 或 Android 平台无效)。 此特性在 Worker 线程中不可用。

The process.seteuid() method sets the effective user identity of the process. (See seteuid(2).) The id can be passed as either a numeric ID or a username string. If a username is specified, the method blocks while resolving the associated numeric ID.

if (process.geteuid && process.seteuid) {
  console.log(`Current uid: ${process.geteuid()}`);
  try {
    process.seteuid(501);
    console.log(`New uid: ${process.geteuid()}`);
  } catch (err) {
    console.log(`Failed to set uid: ${err}`);
  }
}

This function is only available on POSIX platforms (i.e. not Windows or Android). This feature is not available in Worker threads.
