process.setuid(id)

process.setuid(id) 设置进程的用户ID (参阅 setuid(2).) id 可以是一个数值ID也可以是一个用户名字符串. 如果已经有一个用户名，在解析为相关的数值ID时，此方法阻塞。

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}`);
  }
}

注意: 这个方法只在POSIX平台可用(换句话说，Windows或Android不行)。

• 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.
