Script output in NodeJS

Question

I have the following code:

app.get('/scr', function(req, res) {
    var command = spawn(scripts + "/script.sh");
    command.stdout.on('data', function (data) {
        res.send(data);
    });
});

The script outputs Hello World! . I would like to have this output on my browser when going to http://localhost:XXXX/scr . However, this wants me to download a file with Hello World! inside. How can I obtain that output on my browser?

Answer 1

It's likely that the data event will be fired multiple times, but send can only be called once. Rather than using send , use write and end ; or, since command.stdout is a stream, just pipe it into the response:

command.stdout.pipe(res);

You may want to explicitly set the MIME type before that, though, eg:

res.type('text/plain');

Answer 2

您需要设置内容类型。

res.set('Content-Type', 'text/plain');
