How to get the csrf token "outside" laravel view? - laravel

i have a cordova app connected to a laravel api.
I need to make a post from the mobile app to that laravel, but i need the csrf token.
I cannot do the {{csrf_field}} because the view i´m using in the mobile is not provided by laravel so no blade or laravel helpers.
I tried doing a previous ajax call only to get the token, but i don´t know if this is the best way to do it.
Thank you!

In your case I wouldn't recommend to you to get the CSRF token.
Instead I'd suggest you to construct a personal authorization code (per user) or removing the corresponding URLs from the CSRF check (maybe even the whole API).

The token is linked to the currently authenticated user. What you're trying to do won't work.
Try using the API middleware to login and store the token on the mobile app, and use that to identity yourself.

While as the other answers have said, this isn't a recommended solution for your problem, Laravel has a helper function to give you the CSRF token, aptly named csrf_token().
It's listed on the helpers page of Laravel's documentation: https://laravel.com/docs/5.4/helpers#method-csrf-token

Laravel SPA (Vue) Authentication with cookie or token?

the more I read about Laravel Spa (Vue) authentication, the more I ask myself about the "best way" to authenticate with Sanctum.
Official Laravel documentation says:
For this feature, Sanctum does not use tokens of any kind. Instead,
Sanctum uses Laravel's built-in cookie based session authentication
services. This approach to authentication provides the benefits of
CSRF protection, session authentication, as well as protects against
leakage of the authentication credentials via XSS.
But a lot of videos on YouTube or other tutorials on the internet all using (bearer) tokens which sounds contradictory to me. I mean, just using a single token for authentication seems to be a bit unsafe to me.
Also, some of those people defined "login" and "register" routes directly into Laravels route file, instead of using Vue router.
I'm using Laravel 8, VueJS 3 and Vuex 4.
So, what do you think: Am I on the right way by using Vue routes and sanctum authentication using cookies or not? And why?
Thank you, I appreciate that.

How to protect laravel api route from outside access but allow unrestricted access if request comes from frontend?

I'm building the backend with laravel and then using Vue as front-end. Data is accessed over api calls using axios. Now I have this relatively simple task but I can't seem to find the proper solution. I want one of the routes to be easily consumable by Vue compoenents without the need to log in, however I don't want that route to be publicly available for anyone to use.
Things I have tried:
Using passport to protect my routes and then use passport's CreateFreshApiToken middleware. Protection works fine, unauthorized users are not able to access the routes, however I don't get laravel_token in my cookies and therefore I can't get access to that route if I'm not logged in.
Use passport's client credentials grant access. Works fine and the way I want it to work but doesn't really make sense because if I hardcode the client_secret - anyone can access it and then use it to access protected routes. If I make a proxy-like solution, to call a controller method, which would issue a valid token and thus not exposing client_secret to front-end but then anyone could just call that route which issues the token and it would be pointless once again.
Apparently the answer is pretty simple and I was overcomplicating things. I don't know if this is the right/elegant way to do this but basically. If you don't need your api to be accessible from other applications (which I didn't) we can just put routes in web.php instead of api.php. This will ensure that web middleware is used and so it will use the basic csrf token validation, which is totally sufficient for protection against outside requests. You can also leave the route in api.php and just use web middleware on that route. The outcome is exactly what I needed - application is getting data over a route without any need to login AND that route is not available over postman or anything else.

Secured web application with API backend in Laravel

I've created a web application that uses the built-in authentication method for the web, once the user is authenticated he/she is presented with a dashboard page. At this moment Ajax calls to an API need to be made to fetch data for the logged-in user. What would be the correct approach to this to make it is secure?
As a next step, I would like to be able to use the API "stand-alone" as well, so a 3rd party could access the dataset through the API as well.
Right now I am looking into Laravel Passport as well as Spatie Permission package to help me with access control.
If you are using ajax calls in same domain it won't be problem with built-in authentication to give access to authorized users only, because tokens & sessions are accessible for laravel and you can get authenticated users by default.
If you want to make external api as well the best approach will be to use Laravel Passport and pass token in Authorization header as usual.
Hope this helps you

API Security for a Laravel+Nuxt.js project

I have a website which is based on a Laravel backend api and a Nuxt.js frontend app.
The laravel app is served at api.website.com. Till now the api was open, meaning everyone can make a get request. There are almost no post requests.
I know need to implement a login mechanism for the users (Usual login+register and facebook login).
My question is about how would I go to make this process secure. Do I need Laravel Passport (or other similar mechanism)?
My thought is that, say I have an endpoint api.website.com/register (POST), I do not want anyone to be able to just make a post request and create an account. I need to have some sort of security like a csrf token. I know I can use CORS but that doesn't really provide much of security in this case.
You can use jwt like this or laravel passport.

Laravel 5.4: how to protect api routes

I have a react app that fetch datas from laravel api defined like so in routes/api.php:
// this is default route provided by laravel out of the box
Route::middleware('auth:api')->get('/user', function (Request $request) {
return $request->user();
});
// ItemController provides an index methods that list items with json
Route::resource('items', 'Api\ItemController', array('except' => array('create','edit')));
// this is to store new users
Route::resource('users', 'Api\UserController', array('only' => array('store')));
for example http://example.com/api/items returns the data as intended but it's really insecure since anyone could access it through postman.
How to make those routes only accessible inside the app?
As I'm new to it I don't understand if I need to set up api_token and how?
Do I need to setup Passport?
Is is related to auth:api middleware?
It may sounds really basic but any help or tutorial suggestions would be greatly appreciated
EDIT
End up with a classic session auth. Moved routes inside web.php. Pass csrf token in ajax request. Actually i didn't need a RESTful API. You only need token auth when your API is stateless.
As you are using Laravel 5.4 you can use Passport, but I haven't implemented yet, but i implemented lucadegasperi/oauth2-server-laravel for one of my laravel projects and it was developed in Laravel 5.1
Here is the link to github repository
lucadegasperi/oauth2-server-laravel
Here is the link to the documentation Exrensive Documentation
Just add the package to the composer json and run composer update,the package will get installed to your application , once installed add the providers array class and aliases array class as mentioned in the Laravel 5 installation part of the documentation,
you have to do a small tweak in order to work perfectly cut csrf from $middleware array and paste it into $routeMiddleware array and again run php artisan vendor:publish after publishing the migrations will be created and run the migration php artisan migrate
if you only want to secure api routes for each client like ios, android and web you can implement Client Credentials Grant, or if you need to every user with oauth the you can implement Authorization Server with the Password Grant or some other.,
Never use the client id or other credentials, generating access token in the form, but add it some where in helper and attach it in the request to the api,
Hope this answer helps you.
You could use JWT it's pretty easy to get it to work. You basically generate a token by requesting Username/Password and passing that token in every request that requires authentication, your URL would look like http://example.com/api/items?token=SOME-TOKEN. without a proper token, he doesn't have access do this endpoint.
As for
How to make those routes only accessible inside the app?
If you mean only your app can use these requests, you can't. Basically the API doesn't know who is sending these requests, he can only check if what you are giving is correct and proceed with it if everything is in order. I'd suggest you to have a look at this question
