Cordova, how to log in to another server?

Question

PHP

Good day.
There was a task to write a mobile client, but there was a problem with authorization. Cross-domain request to do it turned out like this:

.service('$request', function($q, $http, $ionicPopup, $localStorage) {
        return {
            post: function(r, postData, urlParams) {
                var defer = $q.defer(),
                    url = $localStorage.getObject('user').hostname + r + '?'
                        + _.values(_.mapObject(urlParams || {}, function(v,k) { return k + '=' + v; })).join('&');

                $http({
                    url: url,
                    method: "POST",
                    data: postData || {},
                    headers: {
                        'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'
                    }
                }).then(function(result) {
                    if (!result.data.success) {
                        $ionicPopup.alert({
                            title: 'Ошибка',
                            template: result.data.error
                        });
                        defer.resolve(false);
                    }
                    else {
                        defer.resolve(result.data);
                    }
                });
...

Everything works here and in case of an incorrect password, it displays an error. If you can log in, go to the dashboard and there is an error, the next request requires authorization. I looked at the cookies, it's empty, although there should be a php session identifier. How to properly implement authorization with remembering cookies?
PS Authorization by tokens will not work.

Answer 1

Authorization by tokens will not work.

And it will have to. Well, or shove tokens into cookies, but this makes you vulnerable to CSRF attacks, and in order to protect yourself from this, you still have to send CSRF tokens.
