process.setuid(id)

• id <integer> | <string>

process.setuid(id) 方法设置进程的用户身份。 （请参阅 setuid(2)。） id 可以作为数字 ID 或用户名字符串传入。 如果指定了用户名，则该方法在解析关联的数字 ID 时会阻塞。

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

此功能仅适用于 POSIX 平台（即不适用于 Windows 或安卓）。 此特性在 Worker 线程中不可用。

• id <integer> | <string>

The process.setuid(id) method sets the user identity of the process. (See setuid(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.getuid && process.setuid) {
  console.log(`Current uid: ${process.getuid()}`);
  try {
    process.setuid(501);
    console.log(`New uid: ${process.getuid()}`);
  } 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.
