Question

Ionic Controller
.controller('LoginCtrl', function($scope, $ionicPopup, $state, $http) {
$scope.data = {};
$scope.login = function() {
$http.post('https://mywebsite/login', $scope.email) THIS PART IS TOTALLY WRONG
.success(function(data) {
$state.go('improvements');

I'm trying to login in a web using an ionic APP, so I used inspect element in form log-in from the website that i want login and I got this:
WEB that I want login
<form action="/login" accept-charset="UTF-8" method="post"><input name="utf8" type="hidden" value="✓"><input type="hidden" name="authenticity_token" value="+NAqH2wFj+OC3q5kX3UWLymVHDzpS9ei8a9/F5O8MM76EM6Fhf/RyOVRpCeYmGMtoxzB43Gf70WLbR+1EqD5xA==">
<label for="session_email">Email</label>
<input class="form-control" type="email" name="session[email]" id="session_email">
<label for="session_password">Password</label>
<input class="form-control" type="password" name="session[password]" id="session_password">
<label class="checkbox inline" for="session_remember_me">
<input name="session[remember_me]" type="hidden" value="0"><input type="checkbox" value="1" name="session[remember_me]" id="session_remember_me">
<span>Remember me on this computer</span>
</label>
<input type="submit" name="commit" value="Log in" class="btn btn-primary">
</form>
Anyone could help me ? and I'm so sorry for this newbie question

Answer 1

var params = {
utf8: "the utf8 value"'
authenticity_token : "token value",
session:{
email:"email#mail.com",
password : "apassword"
}
};
$http.post("https://mywebsite/login", params)
.success(function(data) {
$state.go('improvements');
}).error(function(data) {
console.log(data)
var alertPopup = $ionicPopup.alert({
title: 'Login failed!',
template: 'User/Password is Wrong'
});
});
