第二个节点子进程在 linux 上 运行 失败

2nd node child process fails to run on linux

所以我需要一种方法来重新启动我的机器人并最终想出了这个方法,但是当使用 ssh 在 Raspberry Pi 上进行测试时,它会在第一个子进程结束后退出,而在 Windows 不断重复这个循环

运行 使用节点 run.js

run.js

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

var bot;

function startBot() {
  bot = spawn('node', ["bot.js"]);

  bot.stdout.on('data', data => console.log(data.toString()));
  bot.stderr.on('data', data => console.error(data.toString()));

  bot.on('close', code => {
    if (code === 1234) startBot();
  });
}

startBot();

bot.js

setTimeout(() => {
  console.log("child process exiting...");
  process.exit(1234);
}, 5000)

Windows 上的输出:

PS C:\Users\[removed]\Desktop\despacito\despacito-spider\test> node run.js
child process exiting...


child process exiting...

child process exiting...

child process exiting...

child process exiting...

Raspi 上的输出

pi@raspberrypi:~/Desktop/despacito-spider/test $ node run.js
child process exiting...

pi@raspberrypi:~/Desktop/despacito-spider/test $

It is very rare for programs to exit with status codes greater than 128, in part because programmers avoid it due to the $? ambiguity.

将退出代码更改为 2 使其工作
