show current user information from node to angular

Question

I want to show current user information from nodejs to angular(view).

The problem is that i don't know how to pass and how to get User Id in node and angular .

Code :

Node

router.get('/:id/api/data.json', function(req, res, next) {
    console.log(req.params.id);
    var userId = req.params.id;
    User.findById({_id:userId}, function (err, doc) {
        if (err) throw err
        if (doc){
            res.json({
                doc: doc,
                userID:req.params.id
                });
        }
    });
});

Angular :

 app.controller('profileCtrl', function($scope, $http) {
    $http.get("don't know how to get id from node").then(function (response) {
        console.log(response.data);
    });
});

What is output in your browser when you console.log(response.data)? Also, have you tried user res.jsonp() instead of res.json()? The rest looks good to me. — aikorei

Ah, sorry - I skimmed over that part too quickly. You just put in the url that Node is watching: $http.get('/' + id + '/api/data.json').then... Since Node is watching '/:id/api/data.json' this is the url you have to make the $http.get request to. — aikorei

From Angular/your browser? You would need to pass in an ID as a variable. I'll explain in an answer below so I can be a bit more thorough. — aikorei

Your Node.js router is listening to the url /:id/api/data.json. The :id part of that means Node.js is expecting a paramater there, which will get picked up by req.params.id in your Node.js file.

This means that you actually have to be passing in an id value as a part of the url. So your url would look something like /userid12345/api/data.json.

In your Angular file, that's the url you're going to be making the get request to. Which means you need to know the user's ID in your Angular file so you can get that specific url, e.g.:

var userId = 'userid12345';

$http.get('/' + userId + '/api/data.json').then(function(response) {
    console.log(response);
});

Once you pass userId in as a part of the url, then Node can grab it using req.params.id and you can make your db call.

i did this and i got error too : var id = userId i got id is not defined

aikorei Over a year ago

id and userId are just variables that I made up. Do you have an actual user ID in your database? If so, use that, then set your variable in your Angular file to the user ID in your database, i.e. var userId = 'whatever user id is in your database';

_id is in my mongo db , var userId = _id ; i got that error again

_id is set for every db entry in mongo db. What's the value associated with _id in your mongo db entry? It should look something like 574eef74555erss983290f283.
