use Illuminate\Http\Request;

class testvalidationController extends Controller {
   public function showform() {
      return view('login');
   }
   public function validateform(Request $request) {
      $test = file_get_contents('php://input');
      echo $test;
   }
}

_token=zHuIkXpqcRqvZO4vTgxH0fFk5fCmvqSavrCjHVMi&username=testing&password=abcd

Example 2

use Illuminate\Support\Facades\Input;

class testvalidationController extends Controller {
   public function showform() {
      return view('login');
   }
   public function validateform(Request $request) {
      echo Request::createFromGlobals()->getContent();
   }
}

_token=zHuIkXpqcRqvZO4vTgxH0fFk5fCmvqSavrCjHVMi&username=test&password=xya

Example 3

The all() method will return all the form data in an array.

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;

class testvalidationController extends Controller {
   public function showform() {
      return view('login');
   }
   public function validateform(Request $request) {
      $data = Request::createFromGlobals()->all();
      print_r($data);
   }
}
