Question

我正在尝试正常关闭子进程，但从未触发SIGTERM事件。

父母：

const { fork } = require('child_process');

const child = fork('./worker');

child.on('exit', (code, signal) => {
  console.log(`[] Worker ${child.pid} has stopped working. Exit code: ${code}, Signal: ${signal}`);
});
process.on('SIGINT', () => {
  console.log('[] Caught SIGINT: Exiting process...');
  mongoose.disconnect();
});
mongoose.connection.on('disconnected', () => {
  console.log('[] !!! DB Connection closed !!!');
  child.kill(); // Defaults to SIGTERM (https://nodejs.org/api/child_process.html#child_process_subprocess_kill_signal)
});

孩子：

log = (msg) => {
  console.log(`[PID ${process.pid}] ${msg}`);
};
process.once('SIGTERM', () => {
  log('SIGTERM');
});
process.once('SIGINT', () => {
  log('SIGINT');
});
process.once('exit', () => {
  log('exit');
});

关闭数据库后，输出为

[] !!!数据库连接已关闭!!!

[]工作者14920已停止工作。退出代码：空，信号：SIGTERM

发送SIGINT信号时，输出为

[PID 14920] SIGINT

[]捕获SIGINT：正在退出过程...

[] !!!数据库连接已关闭!!!

[]工作者14920已停止工作。退出代码：空，信号：SIGTERM

如何在子进程中处理SIGTERM？

我正在Windows 10 Home（64位）上对其进行测试。

从未在子进程上触发SIGTERM
