success function is not working angular - angularjs

Question

I am sending http request and when that request is finished I am trying to go to another state but the problem is it does not goes in the success callback I thought my be I'm getting an error so I wrote the error callback it does not goes in that to. Can anybody tell me what am I doing wrong
$scope.submitUpdatedData= function(user){
debugger;
// $http.post('/url',{params: value}).sucess(function(){
API.updateRecord(user).success(function(res){
$state.go('app' ,{} , {reload: true });
console.log("Hello");
});
}
The API code is given below. Here I invoke the http call
.factory('API', function($http) {
var api = {};
var baseURL = 'http://localhost:3000';
api.addRecord = function(record) {
console.log(record);
// $http.post(baseURL + '/addData', {name: record.name}.);
return $http.post(baseURL + '/addData', {rec:record});
};
api.deleteRecord = function(id){
return $http.get(baseURL +'/delete/' + id );
};
api.updateRecord = function(user){
return $http.post(baseURL + "/update/" ,{rec:user});
};
api.getAllRecord = function(){
return $http.get(baseURL+'/getAll');
};
api.getOneRecord = function(id){
return $http.get(baseURL + '/getOne/' + id)
};
return api;
})
UPDATE
I have replaced the .success part with then but it still not works
Second Update
This is my server side code
var express = require('express');
var mongoose = require('mongoose');
var util = require('util');
var bodyParser = require('body-parser')
var app = express();
var Schema = mongoose.Schema;
require('node-monkey').start({host: "127.0.0.1", port:"50500"});
var allowCrossDomain = function(req, res, next) {
res.header('Access-Control-Allow-Origin', '*');
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
res.header('Access-Control-Allow-Headers', 'Content-Type');
next();
};
app.use( bodyParser.json() );
app.use(bodyParser.urlencoded({ // to support URL-encoded bodies
extended: true
}));
// app.use(express.json()); // to support JSON-encoded bodies
// app.use(express.urlencoded()); // to support URL-encoded bodies
app.use(allowCrossDomain);
// app.use('/' , require('./index'))
mongoose.connect('mongodb://localhost:27017/myappdatabase');
var userSchema = new Schema({
name: String,
password: String
});
var Todo = mongoose.model('Todo', userSchema);
app.get('/getAll' , function(req, res){
Todo.find({} , function(err , todos){
if (err){
res.send(err);
}
console.log(todos);
res.send(todos);
});
});
app.get('/delete/:name' , function(req , res){
console.log(req.params);
console.log(req.params.name);
Todo.remove({
name : req.params.name
}, function(err, todo) {
if (err)
res.send(err);
// get and return all the todos after you create another
Todo.find(function(err, todos) {
if (err)
res.send(err)
res.json(todos);
});
});
});
app.get('/getOne/:id' , function(req , res){
Todo.find({name : req.params.id}, function(err, todo) {
if (err)
res.send(err);
res.send (todo[0]);
// get and return all the todos after you create another
});
});
app.post('/update', function(req , res){
console.log(req.param('rec').name);
Todo.update({_id:req.param('rec').id} , {$set : {name:req.param('rec').name , password:req.param('rec').password}} , function(err){
if(err)
res.send("Error occured");
res.send("true");
});
});
app.post('/addData' , function(req , res){
console.log( req.param('rec').name);
var p = new Todo({name: req.param('rec').name , password: req.param('rec').password});
p.save(function(err){
if(err){
res.send(err);
console.log(error);
}
res.json(p);
});
});
var server = app.listen(3000, function () {
var host = server.address().address;
var port = server.address().port;
console.log('Example app listening at http://%s:%s', host, port);
});
// module.exports = app;

Answer 1

Seems like success and error are deprecated, you should use then instead:
API.updateRecord(user).then(function(res){
$state.go('app' ,{} , {reload: true });
console.log("Hello");
});
The $http legacy promise methods success and error have been
deprecated. Use the standard then method instead. If
$httpProvider.useLegacyPromiseExtensions is set to false then these
methods will throw $http/legacy error.

Seems like your request is never answered by the API Server. Maybe you can set a timeout for your request. Here it says you can do:
$http.post(url, data, {timeout: 100});
That should timeout your request after 100ms.
