I'm trying to exec a child process in node, the name of which is coming from a post request. I'm using express, hence app.post(). My code is below.
app.post('/*', function(req, res) {
var buf = new Buffer(256);
var cont_len = buf.write(req.url, -1);
var controller = buf.toString('utf8', 0, cont_len);
var controller = controller.concat(' ')
var args = req.param('args', null);
var command = __root+__controllers+controller+args;
console.log(command);
c = exec(command,
function (error, stdout, stderr) {
res.send(stdout);
res.send(stderr);
if (error !== null) {
res.send(error);
}
});
});
The part that doesn't work is when I try and build the command string using a dynamic command. I can hardcode the command variable and it works but when i use the variable 'controller' it doesn't exec my process. Also, is there a way of responding with the return value of the child process or must I stick to only using stdout?
您可以使用req.body访问请求参数
var command = req.body.theparam;
