demo_node.js内容
let express = require('express');
let router = express.Router();
const child_process = require('child_process');
router.post('/', function (req, res, next) {
child_process.execFile('./test.sh',null,null, function (error, stdout, stderr) {
console.log('execFile', stdout, error);
});
res.sendStatus(200)
});
module.exports = router;
使用postman请求可以看到以下错误
> node ./bin/www
execFile { Error: spawn ./test.sh ENOENT
at exports._errnoException (util.js:1016:11)
at Process.ChildProcess._handle.onexit (internal/child_process.js:189:19)
at onErrorNT (internal/child_process.js:366:16)

at process._tickCallback (internal/process/next_tick.js:161:9)
code: 'ENOENT',
errno: 'ENOENT',
syscall: 'spawn ./test.sh',
path: './test.sh',
spawnargs: [],
cmd: './test.sh' }
按照官网的文档按道理是没错的
上面的提示的意思是没找到文件的路径或者没有权限
解决方案
var path = require('path');
...
router.post('/', function (req, res, next) {
var exePath = path.resolve(__dirname, './test.sh');
child_process.execFile(exePath,null,null, function (error, stdout, stderr) {
console.log('execFile', stdout, error);
});
res.sendStatus(200)
});
再执行发现又报错了

提示来看是没有权限，查看test.sh的权限
➜ routes git:(master) ✗ ll test.sh
-rw-r--r-- 1 fangshufeng staff 32B Mar 19 14:57 test.sh
➜ routes git:(master) ✗
发现没有执行权限，修改权限,这里通过数字法修改,不熟悉的可看该篇文章
chmod 777 test.sh
➜ routes git:(master) ✗ ll test.sh
-rwxrwxrwx 1 fangshufeng staff 32B Mar 19 14:57 test.sh
再请求发现好了
POST /demo_node 200 12.843 ms - 2
execFile 这是测试
