http://laravel.com/docs/5.1/validation#other-validation-approaches

and my login method becode like this :

use App\Http\Controllers\APIController;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\model\agents;
use Validator;

class AgentController extends APIController
{

 public function login(Request $request)
    {
        $validator = Validator::make($request->all(), [
            'email' => 'required|email|max:255',
            'password' => 'required|max:255',
        ]);

        if ($validator->fails()) {
            $message = $validator->errors();
            $this->SetStatusCode(404);
            return $this->RespondWithError($message);
        }

Hi Vidi,

As you know, there are many ways to accomplish same task in Laravel, and Laravel is keep evolving. When we write a Laravel application the goal is to keep controllers as clean as possible, and code reusability as much as possible (at least for me).

So with Laravel 5.1 you actually do not need to check if the validator has failed, Laravel will do that and send back all the necessary messages to the view in the $errors object. Meaning with your code you can simplify as such:

  public function login(Request $request)
       {
          $this->validate($request, [
               'email'  => 'required|email|max:255',
               'password' => 'required|max:255'
          ]);
       }

*If any of the validation fails, Laravel sends the request back to the view with $errors object *

That is all you need from your code to send back the error. Also when you're logging user, you probably want to validate for required only, everything else is not necessary for login.

Furthermore, i personally take keeping my controller very clean very serious, so instead of using default Request, i create custom request for all my forms and complete all the validation within the CustomRequest. In your case, i would have created a request called LoginRequest(), import my LoginRequest class and use it on my login method, as result, i do not have to do any validation within my controller.

I hope this helps.

You must add X-Requested-With to header like below:

Content-Type : application/json

X-Requested-With : XMLHttpRequest

With XMLHttpRequest, laravel can received data from Postman. Hope this help you
