How to use Auth::check or Auth::user between different domains? - laravel

I've got a question regarding Laravel framework (vers. 5.2) and the authentication. I have 2 domains which represent a software. let's call them https://azure.mydomain.com and https://azuresoftware.mydomain.com.
The Laravel application is hosted on the domain https://azuresoftware.mydomain.com. https://azure.mydomain.com is just a CMS framework which is providing some information about the website.
Now I want to display different menus, if the user is logged in or not on https://azure.mydomain.com. I thought, I can do a fetch request to https://azuresoftware.mydomain.com/ and use the Laravel methods Auth::check() to check if the user is already logged in or not. I know that this is a CORS fetch request, but this is not the issue. I've allowed in the IIS webserver requests from https://azure.mydomain.com. The request works fine and also just a simple request. But actually Auth::check() is always returning false, even when I'm logged in on the software side.
This is my code so far:
<script>
fetch('https://azuresoftware.mydomain.com/checkLogin', {
method: 'GET',
headers: {
'Content-Type': 'text/plain'
}
})
.then(function(res) {
return res.json()
})
.then(function(data) {
if(data.isLoggedIn) {
// do some stuff...
}
else
{
// do some other stuff...
}
});
</script>
routes.php:
Route::group(['middleware' => 'web'], function () {
...
Route::get('checkLogin', function() {
return json_encode(['isLoggedIn'=>\Auth::check()]);
});
...
I'm sure, I forgot something essential, why it is not working this way.

This is due to the fact that AJAX calls only send cookies if the url you're calling is on the same domain as your calling script.
See Cross domain POST request is not sending cookie Ajax Jquery for more information.

How to redirect properly after logging in in an SPA

I have a situation. I am trying to create an application that will have only one route file, api.php for both the web app (spa) and mobile app.The problem is now that the entire application is stateless (as it should be), I can't even login. Because, routes in api.php expect a token in the request header, which I don't know how to provide.I am using vue in the front-end I have this simple strategy:<button #click="login">Login</button>and the login method looks like this:
login(){
axios.post('login',this.credentials)
.then( window.location = "http://localhost:3000/app" );
}
And my route definition:
Route::group(['middleware' => ['role:admin']], function () {
Route::get('app', function () {
return view('index');
});
});
But it redirects me back to the login page. I wish I could do something like window.header = Bearer myLongToken. I am using JWT, if that helps.
Update:
It looks like there is something else going on. If I remove the role:admin middleware, then I get redirected to desired route, but if I add the middleware, I get redirected back to the login route even if the credentials are valid.
// Route::group(['middleware' => ['role:admin']], function () {
Route::get('app', function () {
return view('index');
});
// });

laravel_token is valid for first request but not subsequent requests

I have installed Laravel Passport and configured it according to the documentation. When calling axios.get from my VueJS file, the first call works as expected. the laravel_session Request Cookie is injected into the request, and the authentication passes, returning the resource.
My problem arises when I try to call the axios.get method again. My use case here is a search function. I'm making a call to /api/banking/accounts/search/{search-term} whenever the user types into a text field, using the code below:
remoteMethod(query) {
if (query !== '') {
this.loading = true;
axios.get(
`/api/banking/accounts/search/${escape(query)}`
).then(res => {
this.destinationAccountDirectory = res.data;
this.loading = false;
});
} else {
this.destinationAccountDirectory = [];
}
},
This code works fine without any auth:api middleware on the route, and for the first time with auth:api middleware. As can be seen from the screenshots below, the laravel_token value changes and is rejected on subsequent calls to the API.
**I've tried to removed the \Laravel\Passport\Http\Middleware\CreateFreshApiToken that was added to the web middleware group during passport installation, which seemed to have temporarily solved the issue, until I receive a 419 on a request shortly after. What could be causing the new laravel_tokens to be rejected? **
I solved this by removing the web middleware from my API route. Why it was there in the first place, I have no idea.
I changed my api.php from
Route::group([
'middleware' => [
'web',
'auth:api']], function() {
Route::post('/banking/transactions', 'TransactionController#store');
Route::get('/banking/accounts', 'BankAccountDirectoryController#index');
Route::get('/accounts/{account}', 'BankAccountDirectoryController#show');
Route::get('/banking/accounts/search/{term?}', 'BankAccountDirectoryController#search');
});
to
Route::group([
'middleware' => [
'auth:api']], function() {
Route::post('/banking/transactions', 'TransactionController#store');
Route::get('/banking/accounts', 'BankAccountDirectoryController#index');
Route::get('/accounts/{account}', 'BankAccountDirectoryController#show');
Route::get('/banking/accounts/search/{term?}', 'BankAccountDirectoryController#search');
});
Should the API routes be under the web group to benefit from the middleware, or is it purely for UI? Am I safe to do this?

Symfony2 send back login form on each AJAX request

I'm doing a back-office image upload form using Symfony 2.5.12 (yeah I know I'm a little out of date, but I will work on that soon :)). I want to upload the images via AJAX, but I get a 302 redirect to the login form on every AJAX request I send.
Here is the JS part on my stuff (it is simplified because for the moment I just want to do a successful AJAX call without 302 redirect to the login page, so I deleted the data related stuff) :
form.addEventListener('submit', event => {
event.preventDefault();
const url = form.getAttribute('action'); // '/admin/uploadImage'
fetch(url)
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error(error));
});
And here is my action in my controller, bound to /admin/uploadImage URL :
public function uploadAction() {
return new JsonResponse(array('test' => 'hello world'));
}
Every /admin URL requires ROLE_ADMIN role, I defined it in security.yml :
security:
#...
access_control:
- { path: ^/admin, roles: ROLE_ADMIN }
This way, it is normal that a login form shows when I want to access to this kind of URL. But when I trigger my AJAX call, I'm already logged in because I'm on /admin/gallery page.
Does anybody can figure out what is wrong with what I'm doing ?
Thank you very much.
I absolutely don't know why, but it seems the issue was related to whatwg-fetch fetch implementation. I replaced it with axios and the problem is gone.

How to use Passport-Facebook login without redirection?

I'm building a phonegap application which will have nodejs at the server side. I wanted to implement login using passport-facebook strategy but their callbacks specify two routes, /successcallback and /failurecallback. Having a single page application, this makes it very confusing to have users redirected to so and so page.
I don't want to serve static files (index.html, login.html) from the server but rather have them on the client and ask the client to make ajax calls. So far, I'm able to make /auth/facebook call as an AJAX request but I can't receive any response on the same request because the login strategy requires the user to be redirected. I'd rather want to send a user_id or name back to the user on successful login or show him the login form (which is also on the www directory in phonegap) on failure. But the redirection and CORS errors are preventing me from doing this. Is there any way I can implement this? I've looked for this since a few weeks now, but no success. I'd really appreciate your help!
PS: I'd rather avoid having to send all html and static content from the node server.
EDIT: Adding login code for better understanding:
app.get('/userpage', utility.isLoggedIn, function(req, res)
{
res.send('User:'+req.user);
});
app.get('/', utility.isLoggedIn, function(req, res)
{
res.redirect('/userpage');
});
app.get('/auth/facebook', passport.authenticate('facebook'));
app.get('/auth/facebook/callback',passport.authenticate('facebook',
{
successRedirect : '/',
failureRedirect : '/login'
}));
app.get('/logout', function(req, res)
{
req.logout();
res.redirect('/login');
});
utility.isLoggedIn:
function isLoggedIn(req, res, next)
{
if (req.isAuthenticated())
return next();
res.redirect('/login');
}
You can't do that with facebook oAuth, but Facebook provides another login solution where you can code your client app to request a token, that you can later validate on the server with passport-facebook-token.
This way you can use the advantages of passport for persistent sessions, without that annoying redirection.
Instead of using the standard redirections offered by passport, you can define your own function which will be executed instead of the redirection. Here's an example of what that code would look like
passport.authenticate('login', function(err, user, info) {
if (err) { return next(err); }
if (!user) { return res.json({ status:"failed", "error": "Invalid credentials" }); }
// req / res held in closure
req.logIn(user, function(err) {
if (err) { return next(err); }
return res.json({ "status":"success"});
})
})(req, res, next);

Django Posts Not Working:

I am using Django 1.2.3 to develop a site. My ajax get requests work fine but the post requests work in development mode (127.0.0.1:8000) but not when I push the site into production using apache + nginx.
Here is an example
urls.py:
(r'api/newdoc/$', 'mysite.documents.views.newdoc'),
views.py
def newdoc(request):
# only process POST request
if request.is_ajax():
data= dict(request.POST)
# save data to db
return HttpResponse(simplejson.dumps([True]))
in javascript:
$.post("/api/newdoc/", {data : mydata}, function(data) { alert(data);}, "json");
my alert is never called .... this is a problem because i want to sanitize this data via a django form and the post requests do not seem to making it to the server (in production only).
what am i doing wrong?
UPDATES:
solution: crsf tokens need to be pushed ajax post requests (not gets) as of django 1.3
also, per the link provide below, the following javascript
$.ajaxSetup({
beforeSend: function(xhr, settings) {
if (!(/^http:.*/.test(settings.url) || /^https:.*/.test(settings.url))) {
// Only send the token to relative URLs i.e. locally.
xhr.setRequestHeader("X-CSRFToken",
$("#csrfmiddlewaretoken").val());
}
}
});
needs to be changed as follows:
$.ajaxSetup({
beforeSend: function(xhr, settings) {
if (!(/^http:.*/.test(settings.url) || /^https:.*/.test(settings.url))) {
// Only send the token to relative URLs i.e. locally.
xhr.setRequestHeader("X-CSRFToken",
$('input[name="csrfmiddlewaretoken"]').val());
}
}
});
the way the csrf token gets rendered in the form must have changed between 1.25 - 1.3??
regardless, it works. thanks for all your help everyone
Can you directly access your javascript files from the production server? Which Django version are you using in production? If you are using 1.2.5+ in production, you will need to push the csrf token to the server during an AJAX post operation.
See the release notes in 1.2.5 and CSRF
To check your Django version:
import django
django.get_version()
Print the above in your production site or from the shell in your production server while making sure you are using the proper Python path.
Your code appears fine with a cursory glance, but I'll show you an example of my ajax form processing code in a hope it'll help with figuring out the error that's occurring. Though, what #dmitry commented should be your first debugging step - use firebug or the inspector to see if the ajax call returns an error.
// js (jQuery 1.5)
$(form).submit(function(event) {
event.preventDefault();
$.post(post_url, $(form).serialize())
.success(function(data, status, jqxhr) {
if (data.success) { // form was valid
$(form)
// other irrelevant code
.siblings('span')
.removeClass('error')
.html('Form Successful');
} else { // form was invalid
$(form).siblings('span').addClass('error').html('Error Occurred');
}
})
.error(function(jqxhr, status, error) { // server error
$(form).siblings('span').addClass('error').html("Error: " + error);
});
});
// django
class AjaxFormView(FormView):
def ajax_response(self, context, success=True):
html = render_to_string(self.template_name, context)
response = simplejson.dumps({'success': success, 'html': html})
return HttpResponse(response, content_type="application/json", mimetype='application/json')
// view deriving from AjaxFormView
def form_valid(self, form):
registration = form.save()
if self.request.is_ajax():
context = {'competition': registration.competition }
return self.ajax_response(context, success=True)
return HttpResponseRedirect(registration.competition.get_absolute_url())
def form_invalid(self, form):
if self.request.is_ajax():
context = { 'errors': 'Error Occurred'}
return self.ajax_response(context, success=False)
return render_to_response(self.template_name, {'errors':form.errors})
Actually, comparing the above to your code, you may need to set the content_type in your django view so that jQuery can understand and process the response. Note that the above is using django 1.3 class-based views, but the logic should be familiar regardless. I use context.success to signal if the form processing passed or failed - since a valid response (json) of any kind will signal the jQuery.post that the request was successful.
