How to set non-standard fields on authorization checks in laravel?

Question

Laravel

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Redirect;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;

class AuthController extends Controller
{
  

  use AuthenticatesAndRegistersUsers, ThrottlesLogins;

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


  protected function validator(array $data)
  {
    return Validator::make($data, [
      'login' => 'required|max:255',
      'email' => 'required|email|max:255|unique:users',
      'pass' => 'required|confirmed|min:6',
    ]);
  }

  
  protected function create(array $data)
  {
    $user=new User;
    $user->login= $data['login'];
    $user->email=$data['email'];
    $user->pass=bcrypt($data['pass']);
    $user->save();
  }

  public function authenticate(Request $request)

  {
    $validator = Validator::make($request->all(), [
      'login'=>'required',
      'pass'=>'required'
    ]);
    $credentials = $this->getCredentials($request);

    if ($validator->fails()) {
      return Redirect::to('auth/login')
        ->withErrors($validator)
        ->withInput();
    } else {
      if (Auth::attempt($credentials)) {
        return redirect()->intended('home');
      }
      return Redirect::to('auth/login')
        ->withErrors('Wrong login/pass');
    }
  }

  protected function getCredentials(Request $request)
  {
    return $request->only('login', 'pass');
  }

}

From here you can see that login and pass are not standard email and password, what to do? Didn't Laravel provide interfaces for this?

Answer 1

Anything can be passed to the attempt method , as long as there is a password field .
It will figure out how to validate it.
PS
If you are very interested in how it works, then you can open the Illuminate\Auth\EloquentUserProvider class and look at the methods: retrieveByCredentials and validateCredentials
