子进程如何配置

Question

主程序

const http=require('http'),
      fs = require('fs'),
      ch=require('child_process'),
var pr=ch.spawn('node',['child.js']),

子进程

process.write("ok")

如何才能正确连接多个进程呢

Answer 1

主程序

const http=require('http'),
      fs = require('fs'),
      ch=require('child_process')
      
var pr=ch.spawn('node',['child.js'],{stdio:'pipe'})

pr.stdout.on('data',function(data){
    //...
})

子进程

process.stdio.write("ok")

掉了stdio和监听子进程输出

Answer 2

一般开发中单线程异步事件处理足以
