LARAVEL5 Custom Login

LARAVEL5 Custom Login

I am working on an application that requires user login.

I have to follow this flow.

User enters login page.
The user submits the login page.
The application checks if the user is in the database 3.1 (If the user is not in the database, it will send a request to a third party and check if the login was successful) 3.2 If the user is in the database, check the password.

Now I made a class for third party and this code will work like

$third = new Libraries\ThirdParty();
$third->login($username, $password);

$third->login

will return true if login succeeded.

Now the question is how to tie this logic together. with laravel predefined functionAuth::check()

When you install laravel it comes with a default input that uses the trait:

class AuthController extends Controller {

    use AuthenticatesAndRegistersUsers;

    /**
     * Create a new authentication controller instance.
     *
     * @param  \Illuminate\Contracts\Auth\Guard  $auth
     * @param  \Illuminate\Contracts\Auth\Registrar  $registrar
     * @return void
     */
    public function __construct(Guard $auth, Registrar $registrar)
    {
        $this->auth = $auth;
        $this->registrar = $registrar;

        $this->middleware('guest', ['except' => 'getLogout']);
    }

}

this class uses the login tag stored in: vendor\laravel\framework\src\Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers.php

you can overwrite methods from this class to put your own logic, for example in the class AuthController

you can define a new one:

function postLogin(){
   //your new logic for login
}

and it will respect your feature instead of the feature function. anyway, the logic is postLogin

from auth trait

:

public function postLogin(Request $request)
    {
        $this->validate($request, [
            'email' => 'required|email', 'password' => 'required',
        ]);

        $credentials = $request->only('email', 'password');

        if ($this->auth->attempt($credentials, $request->has('remember')))
        { //this if validate if the user is on the database line 1
            return redirect()->intended($this->redirectPath());
            //this redirect if user is the db line 2
        }

        return redirect($this->loginPath())
                    ->withInput($request->only('email', 'remember'))
                    ->withErrors([
                        'email' => $this->getFailedLoginMessage(),
                    ]);
          //redirect again to login view with some errors line 3
    }

you can do two things:

edit the tag itself (bad practice) to put your own logic
define your own function postLogin

in AuthController

and copy the logic, but edit it with your own custom logic.

Edit to be more specific with your points:

User enters login page: you can use the default login page that laravel gives you, or you can overwrite the function getLogin

and redirect to your own view.
User submits login page: form action must be: {{ url('/auth/login') }}

or whatever route you specified inpostLogin()
The app checks if the user is in the database: on line 1 of code

3.1 (If the user is not in the database, it will send a request to a third party and check if the login succeeded): in code line 3

3.2 If the user is in the database, check the password: in code line 2
