Run shell script with node.js (childProcess)
提问by Ralf
I want to run a shell script on my node.js server, but nothing happened...
我想在我的 node.js 服务器上运行一个 shell 脚本，但什么也没发生......
childProcess.exec('~/./play.sh /media/external/' + req.params.movie, function() {}); //not working
Another childProcess works perfect, but the process above won't.
另一个 childProcess 工作完美，但上面的过程不会。
childProcess.exec('ls /media/external/', movieCallback); //works
If I run the script in terminal, then it works. Any ideas? (chmod +x is set)
如果我在终端中运行脚本，那么它就可以工作。有任何想法吗？(chmod +x 设置)

The exec function callback has error, stdout and stderr arguments passed to it. See if they can help you diagnose the problem by spitting them out to the console:
exec 函数回调有传递给它的错误、标准输出和标准错误参数。看看他们是否可以通过将它们吐出到控制台来帮助您诊断问题：
exec('~/./play.sh /media/external/' + req.params.movie,
function (error, stdout, stderr) {
console.log('stdout: ' + stdout);
console.log('stderr: ' + stderr);
if (error !== null) {
console.log('exec error: ' + error);
}
});

exec('sh ~/play.sh /media/external/' + req.params.movie ,function(err,stdout,stderr){
console.log(err,stdout,stderr);
})
Runs your play.shshellscript with /media/external/+req.params.movie as argument. The output is available through stdout,stderr variables in the callback.
play.sh使用/media/external/+req.params.movie 作为参数运行您的shellscript。输出可通过回调中的 stdout,stderr 变量获得。
OR TRY THIS
或者试试这个
var myscript = exec('sh ~/play.sh /media/external/' + req.params.movie);
myscript.stdout.on('data',function(data){
console.log(data); // process output will be displayed here
});
myscript.stderr.on('data',function(data){
console.log(data); // process error output will be displayed here
});`
