.save（）在回调函数中不起作用

Question

I'm currently using the "request" module to get data from an external page: if i use the following code, it doesn't work:

request(SITE_URL, function (error, response, body) {
    var user = new gasStation({ id: 12345, name: 'Gustavo' });
    user.save();
});

But if i make the call outside the request function it works as expected:

var user = new gasStation({ id: 12345, name: 'Gustavo' });
user.save();
request(SITE_URL, function (error, response, body) {
  // some stuff
});

Why is this happening?

First never ignore your error handler's. Check if error is true. Also your URL might be malformed check that. Lastly make sure the mongoose model for user is initialized. I only saw initialization outside the request.
