Node.js Worker 'exit'事件用法及代碼示例

事件：'exit'

參數

• code <number> 退出代碼，如果它正常退出。
• signal <string> 導致進程被終止的信號的名稱(例如 'SIGHUP' )。

類似於 cluster.on('exit') 事件，但特定於該工作人員。

import cluster from 'node:cluster';

const worker = cluster.fork();
worker.on('exit', (code, signal) => {
  if (signal) {
    console.log(`worker was killed by signal: ${signal}`);
  } else if (code !== 0) {
    console.log(`worker exited with error code: ${code}`);
  } else {
    console.log('worker success!');
  }
});const cluster = require('node:cluster');

const worker = cluster.fork();
worker.on('exit', (code, signal) => {
  if (signal) {
    console.log(`worker was killed by signal: ${signal}`);
  } else if (code !== 0) {
    console.log(`worker exited with error code: ${code}`);
  } else {
    console.log('worker success!');
  }
});
