[英]how to kill command line process start with child_process nodejs
how can i stop it, it keep running after i stop nodejs.我该如何停止它,它在我停止 nodejs 后继续运行。 I try process.kill() but not working我尝试 process.kill() 但不工作
const process = require('child_process')
const child = process.exec('ping 8.8.8.8 -t')
setTimeout(()=>child.kill(2),10000)
after a few hour reading nodejs docs, i found this for who have same my problem几个小时阅读 nodejs 文档后,我发现这个问题与我的问题相同
const process = require('child_process')
const child = process.execFile('ping 8.8.8.8',['-t'],{cwd:'your working direct'})
setTimeout(()=>child.kill(2),10000)//now kill() working
I modified your code as below to flush out the error:我修改了您的代码如下以清除错误:
const process = require('child_process')
const child = process.spawn('ping 8.8.8.8 -t') // instead of process.exec
setTimeout(() => {
console.log(child.kill(2)) // --> false == failed
}, 10000);
child.on('error', (code, signal) => {
console.log(`${code}`) // --> Error: spawn ping 8.8.8.8 -t ENOENT
});
The ping command requires an argument after the -t ( as per terminal: ping: option requires an argument -- t
ping 命令在 -t 之后需要一个参数(根据终端: ping: option requires an argument -- t
