javascript - How do I specify MongoDB key/value parameters in an $http.get with an AngularJS controller? -

i'm using mean stack web app. in controller.js, have following:

var refresh3 = function() {     $http.get('/users').success(function(response) {         console.log("i got data requested");         $scope.users = response;         $scope.contact3 = "";     }); };  refresh3(); 

this pulls every object in "users" collection mongodb. how add parameters bring back, example, objects "name" : "bob" ? have tried adding parameters in '/users' parentheses using:

$http.get('/users', {params:{"name":"bob"}}) 

i've tried variants of that, no luck. appreciated!

if server receiving data

(and should, $http.get('/users', {params:{"name":"bob"}}) correct)

on server side, make use of query string:

req.query 

like so:

app.get('/users', function(req,res){   if(req.query.name){     db.users.find({"name":req.query.name},function (err, docs) { console.log(docs); res.json(docs); });    }   else{     db.users.find(function (err, docs) { console.log(docs); res.json(docs); });   } });

what issue?

you hinted in comments server set respond app.get('/users') request so:

db.users.find(function (err, docs) {  // docs array of documents in users collection  console.log(docs); res.json(docs); }); }); 

so believe angularjs $http correct, , server receiving parameters {"name":"bob"} should; doesn't know them: set return whole collection in particular case of app.get('/users') request.

how configure server rest

you not have re-invent wheel on server.

rather, consider using middleware automate task (in present case, task issue proper mongodb request when receive query parameters client)

e.g. express-restify-mongoose middleware
